# Combined Anterolateral and Posterior Approach in Total Hip Arthroplasty for Chronic Post-traumatic Hip Dislocation: A Case Report

## TL;DR

A 33-year-old man with chronic hip dislocation from a past accident underwent successful hip replacement using a combined surgical approach.

## Contribution

The paper introduces a combined anterolateral and posterior approach for total hip arthroplasty in chronic post-traumatic hip dislocation.

## Key findings

- The combined approach provided good optical visibility and soft tissue management.
- The patient had no complications during a two-year follow-up.
- The procedure is a viable option for chronic post-traumatic hip dislocation.

## Abstract

Hip dislocation is rare, and it typically results from high-energy trauma such as traffic accidents. Its management involves prompt reduction of the dislocated hip to minimize the risk of subsequent femoral head necrosis. Consequently, cases of chronic hip dislocation are extremely rare. This report presents a case of a 33-year-old male with chronic posterior hip dislocation due to a traffic accident 13 years ago. The left femoral head was completely dislocated posteriorly from the acetabulum, forming a false acetabulum with an arthritic change. The patient experienced difficulty walking and performing daily activities due to pain. We performed a total hip arthroplasty (THA) using a combined anterolateral and posterior approach. The outcome was favorable, with no complications during the two-year follow-up period. THA using a combined anterolateral and posterior approach is a valuable option for patients with chronic post-traumatic hip dislocation because it offers the advantages of optical visibility and the management of the adhered soft tissues.
