Background and Objective: Neglected hip dislocation results in avascular necrosis and arthritis. Therefore the objective of this study was to treat neglected traumatic hip dislocation by total hip arthroplasty and regain good functional activity.

Methodology: This was a retrospective study conducted in Department of Orthopaedics, Dr.Ruth KM Pfau Civil Hospital Karachi from August 2014 to November 2021. Eleven patients were selected. Each patient was assessed clinically and radiologically and was followed up for two years. Thompson & Epstein classification was used for dislocation. Total hip arthroplasty was done in all cases however bone cementing and graft were in accordance with the specific case. Harris hip scoring was performed before and after the surgery to assess functional activity.

Results: There were 10 male and 1 female patient with a mean age of 42.7±10.1 years. Patients suffering from a traumatic accident for 2-5 months were enrolled in this study. Out of 11 patients, 10 were presented with posterior and 1 patient with anterior dislocation. The average Harris hip score preoperatively was 10 and improved to an average of 89post-operatively after two years of follow-up. All patients were treated to their satisfaction.
