Clinical case series shows effective bone union and functional recovery in older patients with distal femur fractures, suggesting locked plating benefits osteoporotic bone.
We treated 16 patients having fractures of the distal femur with the less-invasive stabilization system (LISS). Patients’ mean age was 75 (62–101) years. Fifteen patients had low-energy trauma. Eight fractures were type A (AO classification), three were type B and five were type C. In two cases, loosening of the proximal fixation was seen and surgical revision performed. Union time averaged 30 (16–68) weeks. There was no non-union. Average Oxford knee score was 46 (22–60). No loosening of the distal fixation was found. LISS appears to be an effective device in treating osteoporotic distal femoral fractures.
