Abstract

PURPOSE: Proximal femoral osteotomy (PFO) with periacetabular osteotomy (PAO) improves femoral head coverage in patients with proximal femoral and acetabular dysplasia. Historically, blade plates used in the PFO cause soft-tissue irritation and often lead to implant removal. Here we present a technique using a lower profile pediatric proximal femoral locking compression plate (LCP) for the PFO in a series of adults.METHODS: The results from 13 hips in 11 patients=18years old (age 18-37) with>10months of follow-up are presented.RESULTS: All patients had improved radiographic parameters, pain, and total Merle d'Aubigne-Postel scores postoperatively. Eleven hips (85%) had the LCP removed an average of 15.8±8.6months postoperatively, often due to pain over the greater trochanter.CONCLUSION: The pediatric proximal femoral LCP is effective for PFO in combined PAO PFO procedures but has a high rate of lateral hip discomfort leading to implant removal.
