Background: The purpose of this study was to analyze the initial clinical and radiological results of a consecutive series of selected patients treated in our institution with the same design of resurfacing total hip arthroplasty. We also compared the rate of initial revision surgery with a similar age group who underwent a non-cemented total hip arthroplasty with hard bearings. Methods: Between November 2006 and July 2009, 49 Durom hip resurfacing were performed at our institution in 47 consecutive patients (2 staged bilateral). All patients were men with osteoarthritis; median age 44.5 years old (range 21 to 55). The resurfacing procedure was indicated in young or very active patients with high sports expectation after surgery and following the Schmalzried radiological selection criteria. We performed a clinical and a meticulous digital radiographic analysis in all patients. Results: Postoperative Merle D'Aubigné-Postel score averaged 17.3 points at 43 months of follow-up (range 24 to 62 months). 85% of the patients performed sports activities with an averaged UCLA test 9.5 (range 8-10). One patient (2.04%) underwent a revision femoral component at 15 months of follow-up due to late, non-traumatic femoral neck fracture. The rate of revision in both groups was similar (p = 0.55). Conclusions: Favorable initial clinical and radiological results can be achieved with the use of hip resurfacing system in properly selected young active patients.
