Short term analysis of the functional outcome in complex primary hip arthroplasty

M. Ravi, K. S. Raja


Background: Total hip arthroplasty is the most commonly performed reconstructive procedure that replaces the femoral head, neck and acetabular articular surface. THA is a highly successful procedure that has made numerous patients return to excellent function without pain and provides a stable, pain-free mobile joint. The purpose of this study is short term analysis (retrospective and prospective study) of the functional outcome in 30 patients who underwent complex primary hip arthroplasty.

Methods: A retrospective and prospective study was done to evaluate the functional outcome in 30 patients who underwent complex primary total hip replacement and to analyze the results. A detailed clinical examination and radiological assessment was done to assess the nature of deformity, bone stock, functional impairment and component sizes. Pre-operative templating is routinely done in all cases. Pre-operative clinical evaluation was done using modified Harris hip scoring.

Results: Most of the patient was operated by Hardinge lateral approach (22 Patients). 8 patients were operated by Posterior Southern-Moore approach. In our study the average surgical time delay was 6 days ranging from 5 to 17 days. The average surgical time was 120 minutes ranging from 60 minutes to 3 hours.

Conclusions: The surgical technique employed is unique to each complex case. Surgeon expertise is also a must to deal with complex hips. Complex primary THA is an emerging trend with better clinical and functional outcome with the presently available modular implants and improved surgical techniques.
