Abstract

Introduction: Limb length discrepancy (LLD) is a recognized concern following total hip arthroplasty (THA) for various hip pathologies. THA is a common surgical intervention aiming to alleviate pain and restore function. LLD impacts patient satisfaction and functional outcomes. The main aim of this study was to detect any LLD following THA for a fractured neck or femur, and to focus on the functional outcome of THA in terms of LLD.

Methods: A retrospective study was conducted from January 2019 to December 2021, including all NOF patients eligible for THR based on mobility criteria and clinical assessment. Data were obtained from electronic patient records, postoperative notes, radiographs, and physiotherapy assessments.

Results: There were 58 patients who underwent THA for NOF fractures, average age was 75.6 years (range 62-92 years). The majority (96%) of patients were classified as ASA 2. The time of surgery (TOS) averaged 38.6 hours (range 8-266 hours), with 19 cases experiencing delays of over 36 hours due to surgeon availability. In terms of limb length discrepancy, no patients reported or were documented to have LLD postoperatively. Measurements showed a vertical offset difference mean of 0.47 cm (range 3.46-7.1 mm) and a horizontal offset difference mean of 0.51 cm (range 3.34-6.89 mm) between the operated and normal sides.

Conclusion: LLD post-THR in NOF patients did not appear clinically significant in this study's short-term follow-up. However, radiological evaluations revealed a notable disparity in leg lengths.
