ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of greater trochanteric slide osteotomy(GTSO) in total hip arthroplasty (THA) for the treatment of stiff hip, as well as the potential complications.</p><p><b>METHODS</b>There were 12 cases enrolled in the study from April 2010 to December 2014, including 9 males and 3 females. The mean age was 49.9 years old (ranged, 37 to 62 years old). The clinical result was evaluated according to the Harris evaluation system, and the radiological evaluations included the healing of the osteotomy, the stability of the prosthesis, and occurrence of heterotopic ossification (HA).</p><p><b>RESULTS</b>The mean follow-up period was 17.3 months (ranged, 15 to 22 months). The mean postoperative Harris score was 88.00±6.11, which was significantly higher than the preoperative mean score which was 43.96±8.46(=-18.34,=0.00). All the osteotomy site abtained good healing without prosthesis loosening or HA. There was 1 patient with infection and 1 patient with pain in greater trochanter.</p><p><b>CONCLUSIONS</b>GTSO is an effective exposure technique in THA for stiff hip, and no marked complication associated with the osteotomy is found in the study.</p>
