Abstract：
UNLABELLED:Fractures of the femur after a knee or hip arthroplasty historically have been plagued with high complication rates. The Less Invasive Stabilization System (LISS) has theoretical advantages of improved biomechanics and limited insult to the bone's vascular supply. We theorized that the LISS would have a lower complication rate than historical controls for these fractures. Patients who were treated with a LISS at two Level I trauma centers from July 2001 to July 2003 were prospectively followed up. The inclusion criteria were an acute fracture of the femur treated with a LISS in a patient with a stable ipsilateral total knee prosthesis and/or hip pros- thesis. There were 24 patients in the study group. The injury mechanism was a low-energy fall for all patients. All patients were females with an average age of 79.5 years (range. 64-93 years). Ten patients had ipsilateral hip arthroplasties, nine patients had ipsilateral total knee arthroplasties, and five patients had knee and hip arthroplasties. Followup was at an average of 48 weeks (range, 17-101 weeks). Eighteen of the 19 fractures in the surviving patients with followup healed uneventfully for a complication rate of 5.2%. One fracture was complicated by hardware pullout and was revised to a longer LISS that healed uneventfully. We think our data show that our patients had a low complication rate compared with that of historical controls, and we suggest that the LISS may be an appropriate treatment alternative for femur fractures associated with stable hip or knee prostheses. LEVEL OF EVIDENCE:Therapeutic, Level IV.
