A Case Series Measuring Functional Outcomes in Adult Patients Who Underwent Hip Arthroplasty Using the Modified Trochanteric Slide Approach

Abstract

Background. Different trochanteric osteotomies have been developed to aid in surgical exposure and proper removal and placement of arthroplasty components. Objectives. The study aimed to measure functional outcomes of the modified trochanteric slide approach for both primary and revision hip arthroplasty with radiologic and clinical variables, identify preoperative indications for the approach and identify possible postoperative complications.

Methods. We conducted a retrospective case series of patients who underwent the modified trochanteric slide approach for hip arthroplasty at the orthopedic department of a tertiary hospital from 2012 to 2016. We reviewed patient charts and radiographs. Descriptive statistics were used to analyze data.

Results. Out of nine patients screened, seven were included. The average post-op hip range of motion was 42 degrees abduction and 98 degrees flexion. The union rate was 36% and the non-union rate was 7%.

Conclusion. The modified osteotomy is still recommended for difficult primaries and revisions to aid in exposure and hip biomechanics post-operatively.
