Background

Periprosthetic fracture fixation can be a difficult and complex procedure. The incidence of such fractures is increasing relative to the high prevalence of elderly patients with joint arthroplasty and osteoporosis. Locking plates were introduced for the management of complex periarticular fractures in osteoporotic bone, but there is little information on the use of these plates for the management of periprosthetic fractures. The purpose of this study was to review the early experience with these plates in managing complex Vancouver B1 and C periprosthetic fractures at our academic centre to determine the effectiveness in achieving union, and to identify any potential complications associated with their use.

Methods

We evaluated the results of Vancouver B1 and type C periprosthetic fractures treated with Synthes LCP. The mean age of the patients at the time of surgery was 76 years. 5 patients were men and 10 were women. There were 8 Vancouver B1 and 7 Vancouver C fractures. 6 fractures had failed previous operative treatment. No patient was lost to follow-up. We assessed time to union, complications, and identified criteria for cortical fixation using these plates.


To assess the efficacy of a combined orthoplastic approach to the management of severe grade III fractures of the lower limb, we looked at the functional and radiological outcome of 100 consecutive fractures from a specialist centre.

A prospective analysis was performed on 100 consecutive open tibial fractures (98 patients). An early decision was made by a specialist multidisciplinary team as to whether the injured limb was reconstructable.

In the reconstruction group there were 84 Gustilo grade IIIB/C injuries. Definitive skeletal stabilisation was most commonly with a circular frame (60%) or intramedullary nail (20%). The mean time to union was 26 weeks for diaphyseal fractures, 20 weeks for metaphyseal fractures and 10 weeks for ankle fractures. There was one aseptic non-union which is still undergoing treatment. The anterolateral thigh free flap was the most common soft tissue reconstruction used (42%). There were minimal surgical complications and only one free flap failure. Mean time to follow-up was 24 months. The mean limb functional score (modified enneking) was 83% of that of the normal limb and was not influenced by the site of fracture or type of fixation. The mean SF-36 score was 75 and there was a high return to employment (70%).

In the primary amputation group there were 16 grade IIIB/C injuries. Mean time to follow-up was 38 months. The mean SF-36 score for the below knee amputees was 58 and there was again a high return to employment (58%).

In the reconstruction group there is a 99% limb salvage rate with infection-free union to date and no delayed amputations. A higher return to functional activity/employment was achieved in the reconstruction group compared to the primary amputation group. Our results demonstrate that by using a combined orthoplastic approach in a specialist centre excellent results can be achieved for all patients presenting with severe open lower limb injuries.
