Study summary

The purpose of this study is to compare patient outcomes for the Less Invasive Stabilization System (LISS) (Synthes {USA}, Paoli, PA, USA), a minimally invasive plating system used in the treatment of supracondylar femur fractures, with patient outcomes for the Supracondylar Nail (Smith \& Nephew Inc, Memphis, TN, USA), a retrograde intramedullary nail.

Read the detailed description

All patients who meet the inclusion and exclusion criteria will be randomized into one of two treatment groups. Group A patients will be treated with retrograde intramedullary nailing of the fracture with supplemental screw fixation of the articular portion of the fracture if needed. The Richards supracondylar nail (Smith \& Nephew Richards, Memphis, TN, USA) will be utilized. Group B patients will have their fracture stabilized with the LISS plates (Synthes [USA], Paoli, PA, USA). Supplemental screw fixation of the articular portion of the fracture will occur, if needed. Postoperative care will not be any different than the postoperative care of any other patient undergoing internal fixation of a complex fracture around the knee and based on the patient's overall condition.

Surgical Protocol: After the anesthesia staff has administered general anesthesia, the patient will be positioned on the operating room table as described by the intraoperative technique guide or according to the patient's injury and the surgeon's preference. The patient will be prepped and draped in the usual and customary manner for orthopaedic procedures of the lower extremities. The image intensifier will be available for intraoperative fluoroscopy. The manufacturer's surgical technique guide will be used intraoperatively for implantation of the LISS device and the supracondylar nail. The surgical wound will be closed according to the surgeon's preference. A drainage device may be used if indicated. Routine dressings will be applied. In all instances, immediate postoperative radiographs will be taken to document adequate reduction and fixation. Neurovascular evaluation of the extremity will be performed and documented when the patient emerges from the anesthetic. The patient will be discharged from the recovery room to the postoperative unit when they have met discharge criteria. Routine postoperative orders will be followed until discharge from the hospital.

Patients will be followed in the orthopaedic clinic at predetermined intervals following surgery. The clinic visits will include anterior-posterior and lateral radiographs of the affected extremity and a clinical examination. The patient will also complete the SF-36 (Appendix 1) and a pain scale (Appendix 2). This data will be used to compare the outcomes obtained with the two devices. Clinical follow-up will occur at 2, 4, 8, 12, 18, 26, and 52 weeks following surgery. Radiographs will be obtained at 4, 8, 12, 18, 26, and 52 weeks postoperatively. Patients will complete pain scales at 4, 8, 12, 18, 26, and 52 weeks after surgery. Clinical outcomes will be evaluated at weeks 12, 26, and 52.
