Gliederung

Text

Objectives: Due to distorted anatomy of the proximal femur, modular or custom-made femoral components were favored for total hip arthroplasty (THA) in patients who had a history of Legg-Calve-Perthes disease (LCPD). However, it is unknown whether monolithic cementless stems accommodate the distorted proximal femur with optimal stem version and the results of THA are satisfactory in those patients.

Methods: We reviewed 68 consecutive THAs in patients who were operated due to previous LCPD from June 2003 to December 2008 with a minimum of 5-year follow-up.

Results and Conclusion: Intraoperative calcar fracture occurred in 8 hips (11.8%), which were successfully treated with cerclage wire fixation. The mean stem version was 14.6° (SD; 7.3°, range; -2.3° to 30°). The mean cup abduction and anteversion were 40.2° (SD; 6.5°, range, 23.7° to 56.0°) and 28.3° (SD; 7.6° , range; 6.4° to 43.0°), respectively. The mean follow-up was 8.5 years (range, 62 to 122 months). During the follow-up no dislocations occurred and no hips were revised. At the latest follow-up, the mean Harris hip score was 91 points and the mean UCLA activity score was 3.2.

Monolithic stems reliably restore the anatomy in LCPD without the need for expensive custom implants.
