Comparison of Müller total hip replacement with and without trochanteric osteotomy. Kinesiologic measurements of 82 cases 2 years after surgery.

Function of 37 patients with osteotomy of the greater trochanter during total hip replacement (41 hips) is compared to function of 38 patients (41 hips) without osteotomy. Subjective assessments and cane force measurements were slightly more favorable in the group without osteotomy. Objective measurement of hip motion, hip abductor and adductor muscle strength, weight distribution during standing, and multiple components of free-speed and fast walking showed no statistically significant differences between performance of the groups with and without osteotomy before surgery or 6 months or 2 years after. This suggests that osteotomy provides no functional advantages to the patient beyond those obtained in total hip replacements without osteotomy.
