Mid-term results for hip resurfacing in patients under 30 years old with childhood hip disorders.
The aim of our study was to assess survivorship and function in young patients with hip resurfacing for degenerative arthritis secondary to childhood hip diseases. Data was collected retrospectively using the institutional database and patient notes. Between 1999 and 2012, there were 156 hip resurfacings performed in 143 patients (82 females, 73 males). Mean age at the time of surgery was 21.4 years (12.3 to 30.0). The main indications for surgery included; DDH, AVN, Perthes' and SUFE. Median follow-up was 4.1 years (1.0 to 13.2). Median Oxford scores improved from 54.2 pre-op to 18.8 post-op at a minimum of 2 years follow-up. There were 14 failures. Median head size was 46 mm (45 mm in the failures) For the failures, median cup inclination was 44.4 degrees and anteversion 7.6 degrees. We report the largest single surgeon series of resurfacing hip arthroplasty in the under 30's for childhood hip disorders. 90% 5-year survivorship and good functional outcome can be achieved.
