Warnings: •

The PRECICE STRYDE™ nail cannot withstand the stresses of full weight bearing. Patients should utilize external support and/or restrict activities as directed by the physician until consolidation occurs. • Patients with an open fracture resulting in limb length discrepancy may also have soft tissue damage as a result of severe trauma. It is important that soft tissue damage is addressed prior to lengthening to minimize the risk of infection. • Limb lengthening also involved soft tissues; it is important to allow the soft tissue to heal prior to the lengthening procedure. • Do not use if the sterile packaging has been damaged or appears to have been previously opened. • Metallic implants can loosen, fracture, corrode, migrate, or cause pain. • Due to the presence of a magnet, use of the PRECICE STRYDE™ System is not recommended in patients with pacemakers. • The PRECICE STRYDE™ System may not be appropriate for patients with poly-trauma. • Use of the PRECICE STRYDE™ System in patients with an active infection of the treated bone is not recommended. • Smoking, chronic steroid use and the use of other anti-inflammatory drugs have been determined to affect bone healing and could potentially have an adverse effect of the bone regenerate during the lengthening process. • The PRECICE STRYDE™ nail is supplied sterile and is for single-use only. The nail has not been tested to be cleaned or sterilized for multiple uses. If the nail is used more than once, the device may not be sterile and could cause a serious infection. • The Precice Screws may be provided sterile or non-sterile, take careful note to read packaging if screw is provided sterile or non-sterile. • Before removing the implants from the package, make sure that the protective packaging is unopened and undamaged. If the packaging is damaged, the implants have to be considered as NON-STERILE and may not be used. • Note the STERILE expiry date. Implants with elapsed STERILE expiry dates have to be considered as non-sterile. • Patients with implanted PRECICE STRYDE™ nail should not enter an MRI unit.

•

The PRECICE STRYDE™ System is unsafe in Magnetic Resonance Imaging environments.

•

The PRECICE STRYDE™ Nail should be retracted only by a physician. Retraction should be monitored and confirmed using radiography. There is a possibility of nerve or soft tissue damage and/or weakness related to either

surgical trauma or the presence of the implant. Advise the patient to notify the surgeon of any experienced pain, numbness, or weakness while undergoing treatment. Precautions: •

•

•

Do not use this device without proper training in both device implantation and adjustment. Refer to External Remote Controller (ERC, ERC 2P, ERC 3P, or ERC 4P) Operator’s Manual (OM0005, OM0009, OM0016, or OM0017) for operation of the External Remote Controller. During the distraction phase, patient should not participate in contact sports or other highrisk activities that will cause a load to the treated limb in excess of the maximum patient weight, as identified in the contraindications. Examine all PRECICE STRYDE™ System components carefully prior to use to assure proper working condition. If you suspect a component to be faulty or damaged, do not use.

Cautions: • • •

•

• •

The PRECICE STRYDE™ System is for prescription use only by the order of a physician. Device should be removed after implantation time of no more than one year. Utilize extreme caution when handling instruments made from magnetic materials such as stainless steel in proximity of the magnet of the PRECICE STRYDE™ nail, as materials will be attracted to each other. After the surgical procedure is complete, if retraction is needed during the lengthening or consolidation phase, retract the device no more than the amount lengthened the preceding day. Failure to follow this caution may result in pulling biologic material that may have adhered to the rod into the internal space of the Nail. Do not bend the PRECICE STRYDE™ nail or otherwise modify or damage the implant. Follow the ERC Operators Manual (OM0005, OM0009, OM0016, or OM0017) to assure proper alignment between the ERC and magnet of the PRECICE STRYDE™ nail.

Procedures Careful pre-operative diagnosis and planning, meticulous surgical technique, and extended postoperative care by experienced surgeons are essential to procedure success. Prior to use, the surgeon should be specifically trained in the use of the PRECICE STRYDE™ System along with the associated instruments to facilitate correct selection, placement and security of the implant. Implantation Procedure For fracture reduction applications: 1. Thoroughly clean the instruments according to the parameters in Table 1 or 2 prior to sterilization. 2. Inspect the instruments after cleaning to check for damage prior to sterilization. Functional check should include ensuring mating instruments can be properly assembled and instruments with moving parts are operated to ensure correct operation. 3. Sterilize locking screws (if provided non-sterile) and instrument trays prior to the procedure. The PRECICE STRYDE™ Nail is provided separately in sterile packaging. The Precice Screws are provided non-sterile or sterile, check labeling before proceeding. 4. Position patient per standard technique. 5. Check for length and rotation by comparison to the unaffected limb. 6. Intra-articular fracture components should be addressed with inter-fragmentary screw fixation prior to nail insertion. Care should be taken to place the screws in the anterior and posterior aspect of the distal long bone and safely out of the nail’s intended path. 7. Identify and access the appropriate entry point for the delivery technique chosen (i.e., antegrade or retrograde). 8. Reduce the fracture using standard surgical technique. 9. Determine the appropriate nail size and configuration to be used. • It is recommended to select an implant length that will provide a minimum of 2 cm of housing tube following total lengthening distal to the fracture/osteotomy site. 10. If using flexible reamers, insert a guide wire into the medullary canal and advance until the tip of the wire reaches the intended location. Imaging in two planes is required while advancing the guide wire. 11. Ream the intramedullary canal sequentially in half millimeter increments to a size 1.0 to 1.5 mm larger than the selected nail diameter. 12. After attaching the Drill Guide to the implant, insert the PRECICE STRYDE™ Nail into the medullary canal under image intensification. Advance the PRECICE STRYDE™ Nail until the device is properly positioned. 13. Using the Drill Guide mounted to control alignment, secure the proximal portion of the lengthener using proximal locking screws of appropriate length. The head of the screw should be flush with the bone surface. Do not drill additional holes until securing the previous locking screw. 14. Using a free hand technique and fluoroscopic imaging, secure the distal portion of the lengthener using distal locking screws of appropriate length. The head of the screw should be flush with the bone surface. 15. Remove the Drill Guide and associated accessories and carefully irrigate to remove any remaining bone fragments. Attach the End Cap to the proximal end of the PRECICE STRYDE™ Nail. Carefully irrigate the surgical site to remove any remaining bone fragments. 16. Disassemble the Drill Guide in reverse order from Step 12 prior to cleaning. Clean instruments after use, without allowing instruments to completely dry prior. 17. To provide compression to the reduced fracture, cover the ERC with sterile drape. Locate the ERC magnets over the actuator position and activate the ERC to shorten the implant. The implant may be shortened by up to 10 mm (depending on selected implant) to provide this amount of compression to the reduced fracture. Use radiography to ensure that the implant has retracted the desired amount. LC0259-L-6/2022

18. Locate the center of the implanted magnet and mark with indelible marker. 19. Close and dress the site using standard techniques. 20. Instruct the patient to maintain the indelible marker mark at the same location. For limb lengthening applications: 1. Thoroughly clean the instruments according to the parameters in Table 1 or 2 prior to sterilization. 2. Inspect the instruments after cleaning to check for damage prior to sterilization. Functional check should include ensuring mating instruments can be properly assembled and instruments with moving parts are operated to ensure correct operation. 3. Sterilize locking screws (if provided non-sterile) and instrument trays prior to the procedure. The PRECICE STRYDE™ nail is provided separately in sterile packaging. The Precice Screws are provided non-sterile or sterile, check labeling before proceding. 4. Use standard surgical techniques to provide for adequate venting of the intramedullary canal during surgery. 5. After accessing the insertion site, use an awl or sterile entry drill to open the medullary canal. Use care to keep the straight part of the shaft of the instrument parallel to the long axis of the bone shaft. 6. If using flexible reamers, insert a guide wire into the medullary canal and advance until the tip of the wire reaches the intended location. Imaging in two planes is required while advancing the guide wire. 7. Ream the intramedullary canal 2 mm greater than the diameter of the PRECICE STRYDE™ nail. The cortices must be at least 3mm thick at any location once reamed. 8. Create an osteotomy at the appropriate location in the bone. • Note: Do not perform the osteotomy in the proximal or distal metaphyseal areas where the larger intramedullary canal diameter may lead to instability of the distracted fragment, and higher bending moments may result in excessive loading of the implant. 9. For tibial cases, also create an osteotomy in the fibula. To ensure that the fibula lengthens with the tibia, consider using screws to secure the osteotomized fibula to the tibia both distally and proximally. 10. After attaching the Drill Guide to the PRECICE STRYDE™ nail and tightening down the Locking Bolt and Impactor with a tommy bar or 6mm driver, insert the device into the medullary canal under image intensification. Advance the device until it is properly positioned. 11. Use the Drill Guide to control alignment and then secure the proximal portion of PRECICE STRYDE™ nail using two proximal locking screws of appropriate length. The head of the screw should be flush with the bone surface. Do not drill a second hole until securing the first locking screw. Using a free hand technique and fluoroscopic imaging, secure the distal portion of the PRECICE STRYDE™ nail using two locking screws of appropriate length. The head of the screw should be flush with the bone surface. 12. Remove the Drill Guide and associated accessories. Attach the End Cap to the proximal end of the PRECICE STRYDE™ nail. Carefully irrigate the surgical site to remove any remaining bone fragments. 13. Disassemble the Drill Guide in reverse order from Step 10 prior to cleaning. Clean instruments after use, without allowing instruments to completely dry prior. 14. Locate the center of the implanted magnet and mark the patient’s skin with indelible marker at this location. 15. Close and dress the site using standard techniques. 16. Instruct the patient to maintain the indelible marker mark at the same location on their limb.

Post-Operative Procedures 1. Read the External Remote Controller (ERC) Operator’s Manual (OM0005, OM0009, OM0016, or OM0017) prior to performing an adjustment of the PRECICE STRYDE™ nail. 2. Determine the amount of adjustment required to compensate for any length discrepancy between the treated limb and the unaffected limb or any additional compression or distraction desired. 3. Identify the mark on the limb where the magnet in the PRECICE STRYDE™ nail is located. Carefully place the ERC firmly but comfortably over this area in the correct orientation. 4. Retract or distract the implant to the desired amount, as viewed on ERC display screen. Retraction should only be performed by a physician with the aid of radiography. 5. Carefully place the ERC back in its storage container and close. 6. The progress and efficacy of lengthening should be checked regularly against follow-up radiographic evidence of the rate of lengthening and the quality of the regenerate. While 1 mm per day is generally recommended, clinical and radiographic examination may show that lengthening should progress at a faster or slower pace. Weekly X-ray imaging to assess actual distraction length is recommended. Implant Removal Procedures 1. At the time deemed appropriate by the physician, remove the PRECICE STRYDE™ nail using standard surgical technique. 2. Follow all cleaning and sterilization procedures to prepare the instruments prior to removal. 3. Access the distal end of the PRECICE STRYDE™ nail and attach the removal instrumentation. 4. Once all of the locking screws have been removed, the PRECICE STRYDE™ nail can be removed by using the removal tool assembly which consists of the locking rod, removal rod and the slap hammer. Disassemble removal tool assembly prior to reprocessing after the removal surgery. 5. Close and dress the wound using standard surgical techniques. 6.
