TRIGEN® IM NAIL SYSTEM SURGICAL TECHNIQUE
TRIGEN IM NAIL SYSTEM SURGICAL TECHNIQUE ® Trochanteric Antegrade Nail (TAN™) As Described By Thomas A. Russell, M.D. and Roy W. Sanders, M.D. Nota Bene: The technique description herein is made available to the healthcare professional to illustrate the authors’ suggested treatment for the uncomplicated procedure. In the final analysis, the preferred treatment is that which addresses the needs of the patient. WARNING: This device is not approved for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine. TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES PATIENT PREPARATION 1 Patient is placed supine with unaffected limb extended below the affected limb and trunk. The affected limb is adducted. Flex the affected hip 15°–30°. Apply traction through a skeletal pin or the foot with the fracture table foot holder. Adjust the affected limb for length and rotation by comparison with the unaffected limb. Rotation is further checked by rotating the arm to align the femoral neck anteversion and then making the appropriate correction by foot, usually in 0°–15° of external rotation. This is best checked by visualizing the femoral anteversion proximally and matching it with correct rotation at the knee (Figure 1A). A second option is illustrated in Figure 1B. 2 Palpate the greater trochanter. Make a 1 to 3 cm incision proximal to the greater trochanter. Angle this incision posteriorly at its proximal end. Carry the incision through the fascia (Figure 2). Figure 1A Figure 1B Figure 2 ENTRY PORTAL 3 Assemble the Entry Tool and Honeycomb Insert (7163-1114). The Entry Tool/Honeycomb assembly is oriented so that the superior side of the bevel is medial (NOTE: this requires setting the Entry Tool indicator to “R” for a left nail and to “L” for a right nail which is opposite to the standard FAN technique) and advanced until it rests against the lateral aspect of the greater trochanter. Attach suction to the Entry Tool to assist in blood evacuation and minimize aerosolisation of blood to operative team (Figure 3). Figure 3 2 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES 4 Insert the 3.2 mm tip threaded guide wire through the Honeycomb and advance 1 to 2 cm into the cortex at the tip of the greater trochanter. The guide wires will snap fit into the Mini-Connector (7163-1186), which easily connects to any drill with a “Hall” connector. Once proper placement of the guide wire has been established, the “honeycomb” insert should be removed (Figure 4). Figure 4 Entry Connector 12.5 mm Entry Reamer Channel Reamer Figure 5 Figure 6 5 Tighten the Entry Reamer Connector (7163-1120) onto the 14 mm Channel Reamer (7163-1118) and insert the 12.5 mm Entry Reamer (7163-1116) until it “clicks” into the assembly (Figure 5). Attach the 12.5 mm Entry Reamer to power to ream the proximal section of the femur through the Entry Tool. After removing the first guide wire and the Honeycomb, the Channel Reamer assembly is introduced over the remaining wire and advanced 1 to 2 cm into bone. The reamer assembly is then manipulated under image guidance until the shaft axis and intended path of the reamer form an angle of approximately 5° in the AP view and are in line in the ML view. Caution should be used not to overestimate the angle, as too much insertion angle of the instrument may make advancement more difficult. Once the correct orientation is obtained, the reamer assembly is advanced to full depth. This reamer assembly enlarges the proximal femur 1.0 mm over the diameter of the head of the nail to 14 mm. Remove the 12.5 mm Entry Reamer and guide wire, keeping the Entry Tool and 14mm Channel Reamer in place (Figure 6). 3 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES FRACTURE REDUCTION 6 Snap the T-Handle (7163-1172) onto the Reducer (7163-1124) (Figure 7). Place these through the Entry Tool and 14 mm Channel Reamer to reduce the fracture (Figure 8). Once the Reducer is in the medullary canal and has captured the distal fragment, the 3.0 mm Ball-Tipped Guide Rod (7163-1126) is inserted through the Reducer into the distal femur in the region of the epiphyseal scar (Figure 9). The Gripper (7163-1100) is useful in holding onto the Guide Rod during insertion and removal (Figure 9 Inset). Figure 7 Figure 8 Figure 9 Figure 9 Inset 4 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES CANAL PREPARATION Figure 10 7 Canal preparation is dependent on surgical decision. If reaming is planned, use progressive reamers through the Entry Tool. Unreamed nails are selected based on preoperative planning, but should be of sufficient size to provide translational fill of the intramedullary canal in the mid-diaphysis. Once the Guide Rod is in place, remove the Reducer but leave the 14 mm Channel Reamer in place. Proceed to sequentially ream the femoral shaft to .5 to 1.0 mm or more above the chosen nail diameter through the 14 mm Channel Reamer. For more curved femoral shafts, .5 to 1.0 mm of over reaming may be beneficial (Figure 10). In patients that are very tall, the Flex Reamer Extender (7163-1130) may be added to extend the shaft of the flexible reamer for very distal fractures or nails longer than 42 cm. NOTE: For 13 mm nails, the 14 mm Channel Reamer must be removed before reaming with the 13.5 and 14 mm reamer diameters. NAIL SELECTION 8 Determine nail diameter from image intensifier or templating. Never insert a nail that has a larger diameter than the last reamer used. Figure 11 9 Position the tip of the guide rod at the desired level of the tip of the nail considering fracture patterns and locking screw positioning (Figure 11). Measure the nail length by positioning the open end of the Ruler (7163-1128) over the exposed end of the guide rod pushing the end down to the level of bone through the 14 mm Channel Reamer. Confirm the position on the image intensifier. The tip of the Ruler should line up with the step on the 14 mm Channel Reamer for correct length measurement. The end should be at the tip of the piriforma fossa for the TAN Recon mode. Use preop templating for correct length measurement, as excessive countersinking may require as much as a 2 cm shorter nail length adjustment. Read the nail length from the calibrations exposed at the other end of the Ruler. Leave the guide rod in place for placement of the nail. Exchange of the ball-tipped guide rod is not necessary. 5 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES DRILL GUIDE ASSEMBLY FEMORAL MODE 10 Insert the Guide Bolt (7163-1136) into the Drill Guide (7163-1134) and use the Guide Bolt Wrench (7163-1140) to secure the bolt to the nail. Screw the Impactor onto the top of the Drill Guide to drive the nail into the medullary canal (Figure 12). Insert the Skin Protector (7163-1132) in the incision parallel to the Entry Reamer Tool. Remove the Entry Reamer Tool and 14 mm Channel Reamer. The Skin Protector will assist in maintaining control of the surrounding tissues and provide continued access to the bone. Advance the nail over the guide rod and carefully past the fracture. As the nail is inserted, it is rotated so the bow is pointed lateral. During advancement, the nail may be rotated to allow proper positioning and seating of the proximal section if needed. Due to the greater trochanter entry point, it may be necessary to countersink the nail more than a FAN to ensure the proximal locking screws are positioned appropriately. At this point the standard FAN technique may be followed. Remove the guide rod after the nail is inserted and before inserting the locking screws (Figure 13). Lime = Left Rose = Right Figure 12 Figure 13 INTERLOCKING FOR FEMORAL MODE 5.0 mm (GOLD) screws are to be used to lock the 10 mm, 11.5 mm and 13 mm TAN Implants. 11 Proximal Screw: To place screws at a 45° angle from the greater to lesser trochanter, the following options are available (Figure 14): A. PREDRILLING TECHNIQUE — Make a stab incision at the entry hole and push the Gold Outer Drill Sleeve (7163-1152) through the drill guide hole until it is touching the lateral cortex. Introduce the Silver Inner Drill Sleeve (7163-1156) through the Gold Outer Drill Sleeve. Attach the Long Pilot Drill (7163-1110) to power using the Mini-Connector (7163-1186). The length measurements are taken 6 Figure 14 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES Figure 15 Figure 16 Figure 17 from the calibrations off the drill in relation to the end of the Silver Inner Drill Sleeve (Figure 15). The appropriate length 5.0 mm screw (GOLD) is selected and attached to the Screwdriver. The drill and Silver Inner Drill Sleeve are removed and the screw is inserted through the Gold Outer Drill Sleeve. Attach Screwdriver to power or use manual T-Handle (7163-1172) and place screw in bone. The Screwdriver contains a laser-marked ring. This ring should be stopped short of the Gold Outer Drill Sleeve to prevent final seating of the screw by power. It is recommended that final tightening of the 5.0 mm screw should always be under manual control using the T-Handle (7163-1172) (Figure 16). B. SCREW LENGTH GAUGE — Pre-drill through both cortices. Insert the Screw Length Gauge through the Gold Outer Drill Sleeve (7163-1152) from the far cortex to measure for proper 5.0 mm screw (GOLD) length. The appropriate length 5.0 mm screw (GOLD) is selected and attached to the Screwdriver (Figure 17). Attach Screwdriver handle to power or use manual T-handle (7163-1172) and place screws in bone. The Screwdriver contains a laser-marked ring. This ring should be stopped short of the 9 mm Drill Sleeve to prevent final seating of the screw by power. It is recommended that final tightening of the 5.0 mm screw should always be under manual control using the T-Handle (7163-1172) (Figures 18 and 19). Figure 18 Figure 19 7 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES DRILL GUIDE ASSEMBLY RECON MODE (Also Applies to Trochanteric Nail) 6.4 mm (BLUE) screws are to be used to lock the 10 mm, 11.5 mm and 13 mm diameter TAN Implants proximally in the Recon mode. 5.0 mm (GOLD) screws are to be used to distal lock 10.5 mm, 11 mm and 13 mm TAN Implants. 10 Insert the Guide Bolt (7163-1136) into the Drill Guide (7163-1134) and use the Guide Bolt Wrench (7163-1140) to secure the bolt to the nail. Connect the Hip Guide (7163-1144) to the Drill Guide. The guide is keyed so that it will only fit one way. Tighten the knurled knob by hand until snug. Use the end of the Guide Bolt Wrench (7163-1140) to finish tightening the guide in place. Check the alignment of the guide to the screw holes by passing the Medium Screwdriver (7163-1166) through the Gold Outer Drill Sleeve (7163-1152) up into the holes of the nail. Screw the Impactor onto the top of the Drill Guide to drive the nail into the medullary canal (Figure 19). Insert the Skin Protector (7163-1132) in the incision parallel to the Entry Reamer Tool. Remove the Entry Reamer Tool and Channel Reamer. The Skin Protector will assist in maintaining control of the surrounding tissues and provide continued access to the bone. Advance the nail over the guide rod and carefully past the fracture. Remove the guide rod after the nail is inserted and before inserting the locking screws (Figure 20). If insertion is difficult, place the bow of the nail lateral and rotate during insertion to more easily place the nail. 8 Figure 19 Figure 20 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES INTERLOCKING FOR RECON MODE Figure 21 Figure 22 11 PROXIMAL SCREWS: Two aspects of screw placement into the femoral head must be noted before drilling into the femoral head. (1) Alignment of the anteversion, and (2) Depth of nail insertion. To begin, rotate the C-Arm proximally until a true line of the hip is visualized, this gives the correct axis of alignment for anteversion. Rotate the handle of the nail guide until it bisects the femoral head in the lateral view. This should assist in setting the correct anteversion position of the screws. Mark this position with a skin marker on the leg parallel to the driving handle. Next, rotate the C-Arm into an A/P view using the calibrated notches on the proximal attachment of the nail, which is visualized radiographically, to determine from preoperative planning what depth of nail insertion will be required to allow both screws to be centered in the head. As a rule, the inferior screw is placed first, though in situations where the neck is large enough, the proximal screw can be placed, again, approximately 4-5 mm from the superior cortical margin of the femoral neck. These screws are angled at 135° in relation to the shaft. If both screws will not seat within the femoral head, it is probable that too much varus positioning of the proximal fragment has occurred, or the proximal nail entry portal is too lateral (Figure 21). A. 6.4 mm Screw Placement Technique — Make an incision at the entry holes of the proximal screw sleeves, and then connect the two puncture wounds for approximately a 3 cm incision that will accommodate the insertion of both screws. Insert the Silver Inner Drill Sleeve (1163-1156) into the Gold Outer Drill Sleeve (7163-1152) and push to bone. Insert the Tip Threaded Guide Pin (7163-1190) into the Silver Inner Drill Sleeve (7163-1152) and connect to power using the Mini-Connector (71631186). Drill into the femoral neck and head to the desired depth and position (Figure 22). Drill the 9 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES femoral neck with the 6.4 mm Drill (7163-1160) to slightly less than the depth desired. Check the alignment in A/P and 15° lateral views again before removing the 6.4 mm drill. Use the 6.4 mm Tap (7163-1162) through the drill sleeve to prepare the bone for screw insertion (Figure 23). Measure the depth for the screw length from the calibrations on the drill or tap with respect to the Gold Outer Drill Sleeve. Attach the appropriate length 6.4 mm screw (BLUE) to the Medium Screwdriver (7163-1166). Attach Screwdriver handle T-Handle (7163-1172) and insert captured screw into the inferior proximal hole, but do not tighten. Once the first screw is inserted, do not disassemble the Screwdriver. Repeat the procedure for the suyperior screw with the Long Screwdriver (7163-1164) (Figures 24 and 24 Inset). Tighten the proximal screws when the traction is released to maximize compression at the fracture site. Once an acceptable position is obtained, detach the Screwdriver from the screws, proximal locking is complete (Figure 25). Figure 23 Figure 24 Figure 24 Inset Figure 25 10 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES Proper Screw Measurement ä All TriGen locking screw measuring devices, measure from bottom of head to the last complete thread of screw. This is the working length of the screw. Thus, the screw itself is longer than the measurement and adding length is not necessary. Figure 26 Figure 27 12 DISTAL SCREWS FOR STANDARD TAN: Perform distal locking with the standard TAN with the Cole Radiolucent Drill or Freehand Technique. The Freehand technique is used with the C-Arm placed medial to the patient, allowing for proper image of the femur. Make adjustments to the C-Arm until perfect circles are visualized. For the short TAN (Blue), distal locking is performed by attaching the 8.5 mm FAN Guide (7163-1119) with the Blue Tip for targeting the distal holes. Make a stab incision over the holes of the image and then one of the following techniques may be used (Figure 26). A. Predrilling Technique — After perfect circles are confirmed, a stab incision is made over the holes. Confirm the alignment and attach the Long Drill (7163-1110) to power using the Mini-Connector (7163-1186). Insert the drill through both cortices. Remove the Mini-Connector and push the Silver Inner Drill Sleeve (7163-1156) to bone over the drill. The length measurements are taken from the calibrations off the drill in relation the Silver Inner Drill Sleeve to bone (Figure 27). The appropriate length screw is selected and attached to the Screwdriver. Remove the Drill and Silver Inner Drill Sleeve. Attach Screwdriver handle to power or use manual T-handle (7163-1172) and place screws in bone. It is recommended that final tightening of the screw should always be under manual control using the T-Handle (7163-1172) (Figure 28). Figure 28 11 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES B. Screw Length Gauge — Predrill through both cortices. Insert the Gold Outer Drill Sleeve (7163-1152) to bone. Insert the Screw Length Gauge through the Gold Outer Drill Sleeve from the far cortex to measure for proper screw length (Figure 29). The appropriate length screw is selected and attached to the Screwdriver. Attach Screwdriver handle to power or use manual T-handle (7163-1172) and place screws in bone (Figure 30). It is recommended that final tightening of the screw should always be under manual control using the T-Handle (7163-1172). C. (Optional) Power Technique — The distal interlocking technique can be performed without a guide by the freehand method. This can be done by placing the Ruler (7163-1128) on top of the leg and taking a C-arm image. Count the number of grooves between the edge of the Ruler and the far cortex. The grooves are 5 mm apart. The Ruler should be placed against the edge of the near cortex for the best measurement. The screw length should be adjusted 3-5 mm longer for magnification error correction to ensure that the far cortex is reached. The proper length screw is attached to the Screwdriver. After “perfect circles” are confirmed, insert the screw into bone through the Gold Outer Drill Sleeve (7163-1152) using power. The Screwdriver contains a laser-marked ring. This ring should be stopped short of the Gold Outer Drill Sleeve to prevent final seating of the screw by power. It is recommended that final tightening of the screw should always be under manual control using the T-Handle (7163-1172) (Figure 31). D. Targeter — The Targeter (7163-1174) may be used to assist in placing additional distal screws after the first screw has been inserted (Figure 32). Be sure to use the Medium Screwdriver (7163-1166) when placing the first screw in bone as outlined in the above options. Leave the Medium Screwdriver attached to the first screw in the bone. Choose whether you will be “statically” or “dynamically” 12 Figure 29 Figure 30 Figure 31 Figure 32 TROCHANTERIC ANTEGRADE SURGICAL TECHNIQUE FOR STANDARD FEMORAL OR RECON LOCKING MODES locking the implant. Place the appropriate labeled hole on the Targeter over the Screwdriver and push to skin. Making sure that the Targeter can freely rotate. The Short Screwdriver (7163-1168) can also be attached to the side of the Targeter. It acts as a handle to stabilize the Targeter as well as an aid in reducing exposure of the hand during imaging. Use the C-Arm to rotationally locate the second hole. Once the position is found, place the Short Drill (7163-1112) through the wire hole on the Targeter and into bone to maintain position. The MiniConnector (7163-1186) provides a convenient attachment of the drill to power. Make an incision at the tip of the barrel for the second screw and insert the Silver Inner Drill Sleeve and Targeter to bone. Use of the standard pre-drill technique or power technique can be used to finish screw placement (Figure 33). The optional power technique can also be used for the second screw by removing the Silver Inner Drill Sleeve (Figure 34). Figure 33 Figure 34 Figure 35 Figure 36 13 DISTAL SCREWS FOR SHORT TAN (BLUE): For the short TAN, distal locking is performed by attaching the 8.5 mm Grey FAN Guide (7163-1119) with the Blue Tip. The blue tip is designed to provide guided targeting of the distal screw holes in the Short TAN implants (Figure 35). CLOSURE 14 On completion of the procedure, the proximal guide is removed with the Guide Bolt Wrench (7163-1140), wounds are irrigated and closed in a standard fashion (Figures 36, 37 and 38). Figure 37 Figure 38 13 SURGICAL TECHNIQUE FOR TRIGEN NAIL CAPS WITH TAN TriGen Nail Caps are available in 5 mm (7163-3005), 10 mm (7163-3010), 15 mm (7163-3015) and 20 mm (7163-3020) sizes to accommodate most countersinking needs. The cap length includes the external driving hex. ASSEMBLY AND PLACEMENT WITH FAN 1. The proper cap is chosen based on the amount of countersinking measured on preoperative templates or from the drill guide countersinking measurements. 2. It is recommended that the polyethylene plug be removed in nail caps being used for Trochanteric Antegrade Nails. Removing the plug allows for easier removal using a guided approach if the nail has to be removed. Use the Obturator (7163-1122) to press on and expel the polyethylene plug located inside the nail cap. 3. After removal of the plug, attach the nail cap to the Long Captured Screwdriver (7163-1164). 4. Insert the nail cap through the incision and tighten it to the nail. Be sure to properly align the nail cap to the nail to prevent cross threading. Some resistance may be felt. This is due to a pennig process to the threads designed to minimize backout. 5. Reconfirm that the nail cap is properly located all the way down to the nail. 1. Make a 1 cm to 2 cm incision in approximately the same location as the original incision used to place the nail. 2. Locate the nail cap. 3. Place a 3.2 mm Guide Wire (7163-1190) into the cannulation of the nail cap. 4. Place the 12.5 mm Entry Reamer (7163-1116) down to the nail cap and use to clear debris. 5. Remove the retaining shaft from the Long Captured Screwdriver (7163-1164). 6. Attached the T-Handle (7163-1172) to the screwdriver (7163-1164). 7. Place the screwdriver over the 3.2 mm Guide Wire (7163-1190) and secure to the external hex of the nail cap. 8. Remove the guide wire. 9. Remove the T-Handle and replace the retaining shaft back inside the screwdriver. 11. Remove the nail cap. NAIL CAPS 14 The TriGen Nail Cap was designed to allow for a percutaneous and captured approach when removing from an Antegrade Nail as follows: 10. Reattach T-Handle and secure the captured screwdriver to the nail cap. 6. Disconnect the Captured Screwdriver. Cat.

When removing a TriGen nail, the Large Extractor (7163-1178) is always used. For nails other than TriGen, the Large Extractor is designed to remove diameters greater than 10 mm. The Small Nail Extractor (7163-1176) is designed for 10 mm diameters or smaller nails. These two nail extractors are designed to remove virtually any nail. STANDARD TECHNIQUE FOR LARGE OR SMALL EXTRACTOR Standard Technique for Large or Small Extractor 1. Patient is placed in correct position on a radiolucent table for imaging. 2. Make a 1 cm to 2 cm incision in approximately the same location as the original incision used to place the nail. 3. Place the 3.2 mm Tip Threaded Guide Wire (7163-1190) into the top of the nail. 4. Insert the 12.5 mm Entry Reamer (7163-1116) to the top of the nail and use to clear debris and overgrowth. 5. After debris has been cleared, remove the guide wire and Entry Reamer and assemble the Impactor to the appropriate extractor. 6. The extractor is placed through the incision down to the top of the nail and screwed into the nail using slight, downward pressure. Be sure to check alignment of the extractor and nail to make assembly easier. 7. After the Extractor is tightened to the nail, the Guide Bolt Wrench (7163-1140) is placed into the hole on the Impactor (7163-1185) handle to provide additional leverage. OPTIONAL CANNULATED TECHNIQUE FOR LARGE EXTRACTOR ONLY MOST USEFUL WHEN REMOVING ANTEGRADE FEMORAL NAILS 1. Patient is placed lateral decubitus on a radiolucent table for imaging. 2. Make a 1 cm to 2 cm incision in approximately the same location as the original incision used to place the nail. 3. Place the 3.2 mm Tip Threaded Guide Wire (7163-1190) into the top of the nail. 4. Insert the 12.5 mm Entry Reamer (7163-1116) over the guide wire to the top of the nail and use to clear debris and overgrowth. 5. Once the debris is cleared, remove the Entry Reamer, leaving the 3.2 mm Tip Threaded Guide Wire in place. 6. Assemble the One-Piece Impactor (7163-1185) to the Large Extractor. 7. The Large Extractor is placed over the wire and guided to the top of the nail. The Extractor is screwed into the nail using slight downward pressure. 8.

No. 7112-9402 23 IMPORTANT MEDICAL INFORMATION INTRAMEDULLARY NAIL SYSTEM SPECIAL NOTE The Intramedullary Nail System consists of interlocking intramedullary nails, and interlocking fusion nails, and pins. Intramedullary nails contain holes proximally and distally to accept locking screws. Components are available in many styles and sizes and are manufactured from various types of metals. The component material is provided on the outside carton label. Use only components made from the same material together. Do not mix dissimilar metals or components from different manufacturers. Refer to manufacturer literature for specific product information. All implantable devices are designed for single use only. Intramedullary Interlocking Nails are provided with a variety of screw placement options based on surgical approach, antegrade or retrograde, and indications. Interlocking Fusion Nails indicated for joint arthrodesis have screw holes for locking on either side of the joint being fused. The locking screws reduce the likelihood of shortening and rotation of the fusion site. INDICATIONS The general principles of patient selection and sound surgical judgment apply to the intramedullary nailing procedure. The size and shape of the long bones present limiting restrictions on the size and strength of implants. Indications for interlocking intramedullary nails include simple long bone fractures; severely co mminuted, spiral, large oblique and segmental fractures; nonunions and malunions; polytrauma and multiple fractures; prophylactic nailing of impending pathologic fractures; reconstruction, following tumor resection and grafting; supracondylar fractures; bone lengthening and shortening. Interlocking intramedullary nails are indicated for fixation of fractures that occur in and between the proximal and distal third of the long bones being treated. In addition to the indications for interlocking intramedullary nails, devices that contain holes/slots proximally to accept screws that thread into the femoral head for compression and rotational stability are indicated for the following: subtrochanteric fractures with lesser trochanteric involvement; ipsilateral femoral shaft/neck fractures; and intertrochanteric fractures. 2. Surgical technique information is available upon request. The surgeon should be familiar with the devices, instruments and surgical technique prior to surgery. 3. The use of locking screws is necessary for strength and compatibility. Please refer to the surgical technique or product catalogue for information on the correct size of screws for each nail. 4. The patient should be advised that a second more minor procedure for the removal of implants is usually necessary. 5. While the surgeon must make the final decision regarding implant removal, wherever possible and practical for the individual patient, fixation devices should be removed once their service as an aid to healing is accomplished. In the absence of a bursa or pain, removal of the implant in elderly or debilitated patients is not suggested. 6. Postoperative instructions to patients and appropriate nursing care are critical. Early weight bearing substantially increases implant loading and increases the risk of loos ening, bending or breaking the device. Early weight bearing should only be considered where there are stable fractures with good bone-to-bone contact. Patients who are obese and/or noncompliant, as well as patients who could be pre-disposed to delayed or non-union, must have auxiliary support. The implant may be exchanged for a larger, stronger nail subsequent to the management of soft tissue injuries. 7. Even after full healing, the patient should be cautioned that refracture is more likely with the implant in place and soon after its removal, rather than later, when voids in the bone left by implant removal have been filled in completely. 8. Patients should be cautioned against unassisted activity that requires walking or lifting. 9. Postoperative care and physical therapy should be structured to prevent loading of the operative extremity until stability is evident. 10. Additional postoperative precautions should be taken when the fracture line occurs within 5 cm of the nail’s screw hole, as this situation places greater stress on the nail at the location of the transverse screw hole. In addition to the indications for interlocking intramedullary nails, devices that utilize a retrograde femoral surgical approach are indicated for the following: severely co mminuted supracondylar fractures with or without difficult intra-articular extension; fractures that require opening the knee joint to stabilize the femoral condylar segment; fractures above total knee implants. POSSIBLE ADVERSE EFFECTS Indications for the Knee Nail include the following: degeneration, deformity, or trauma of both the tibiotalar and talocalcaneal articulations in the hindfoot; tibiocalcaneal arthrodesis; combined arthrodesis of the ankle and sub-talar joints; avascular necrosis of the ankle and sub-talar joints; failed total ankle replacement with sub-talar intrusion; failed ankle arthrodesis with insufficient talar body; rheumatoid arthritis; severe deformity secondary to untreated talipes equinovarus or neuromuscular disease; and severe pilon fractures with trauma to the sub-talar joint. 3. Infections, both deep and superficial, have been reported. 1. Loosening, bending, cracking or fracture of the implant components. 2. Limb shortening or loss of anatomic position with nonunion or malunion with rotation or angulation may occur. 4. Irritational injury of soft tissues, including impingement syndrome. 5. Supracondylar fractures from retrograde nailing. 6. Tissue reactions which include macrophage and foreign body reactions adjacent to implants. Knee Fusion Nails are intended for intramedullary knee arthrodesis. 7. Although rare, metal sensitivity reactions and/or allergic reactions to foreign materials have been reported in patients. CONTRAINDICATIONS PACKAGING AND LABELING 1. These systems should not be used in crossing open epiphyseal plates. 2. Insufficient quantity or quality of bone, obliterated medullary canal or conditions which tend to retard healing, also, blood supply limitations, previous infections, etc. 3. Active infection. 4. The presence of a previously inserted fracture fixation device. 5. Preexisting bone deformity. 6. Hypovolemia, hypothermia and coagulopathy. 7. Mental conditions that preclude cooperation with the rehabilitation regimen. 8. The forearm nail should not be used in children who have not reached skeletal maturity. WARNINGS 1. This device is not approved for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine. 2. Intramedullary nails are neither intended to carry the full load of the patient acutely, nor intended to carry a significant portion of the load for extended periods of time. 3. The correct selection of device components is extremely important. The appropriate type and size should be selected for the patient. Failure to use the largest possible components or improper positioning may result in loosening, bending, cracking, or fracture of the device or bone or both. 4. Do not mix dissimilar metals. Use only stainless steel screws with stainless steel devices, and Ti-6A1-4V screws with Ti-6A1-4V devices. PRECAUTIONS 1. Use care in handling and storage of implant components. Cutting, sharply bending or scratching the surface can significantly reduce the strength and fatigue resistance of the implant system. This, in turn, could induce cracks and/or noninternal stresses that could lead to fracture of the implants. 3433199 Rev. 0 24 Components should only be accepted if received by the hospital or surgeon with the fac tory packaging and labeling intact. STERILIZATION/RESTERILIZATION Most implants are supplied sterile and have been packaged in protective trays. The method of sterilization is noted on the package label. All radiation sterilized components have been exposed to a minimum of 25 kiloGrays of gamma radiation. If not specifically labeled sterile, the implants and instruments are supplied non-sterile and must be sterilized prior to use. Inspect packages for punctures or other damage prior to surgery. Metal components may be initially sterilized or resterilized, if necessary, by steam autoclaving in appropriate protective wrapping, after removal of all original packaging and labeling. Protect the devices, particularly mating surfaces, from contact with metal or other hard objects which could damage the product. The following process parameters are recommended for these devices: • Prevacuum Cycle: 4 pulses (Maximum = 26.0 psig (2.8 bars) & Minimum = 10.0 inHg (339 millibars)) with a minimum dwell time of 4 minutes at 270°F to 275°F (132°C to 135°C), followed by a 1 minute purge and at least 15 minutes of vacuum drying at 10 inHg (339 millibars) minimum. • Gravity Cycle: 270°F to 275°F (132°C to 135°C) with a minimum dwell time at temperature of 15 minutes, followed by a 1 minute purge and at least 15 minutes of vacuum drying at 10 inHg (339 millibars) minimum. Smith & Nephew does not recommend the use of low temperature gravity cycles or flash sterilization on implants.
