Subtrochanteric shortening and uncemented arthroplasty in hips with high dislocation - a cohort study with 13-30 years follow-up.

Introduction: The aim was to evaluate short- and long-term outcomes in patients with high hip dislocation operated with subtrochanteric shortening osteotomy and uncemented total hip arthroplasty.

Methods: Sixty-five hips operated in 1986-2001, at mean age 48 years (15-79), were followed for mean 19 years (13-30).

Results: At last follow up, there were two femoral and 35 acetabular revisions. Harris hip score was mean 86 (81-90) in unrevised, and 87 (82-90) in revised hips.

Conclusions: Our study shows favorable long-term results for a fully hydroxyapatite (HA) coated stem. Aseptic cup-loosening may be reduced by using better implants.
