Hip dislocation after total hip arthroplasty can be classifi ed into anterior and posterior dislocation, and immediate post-op and late dislocation. The most common dislocation is posterior dislocation which depends on a primary surgical approach because the resection of the posterior capsule takes part in the direction of hip dislocation. However, surgical technique, components orientation and soft tissue tension have a major role in hip stability. We report a case of a 52-year-old man who suffered from an unstable hip after having a normal hip functional score for 13 years without any traumatic events. Radiographic fi ndings did not show any sign of loosening or radiolucency. The causes of late hip dislocation and treatment are also described.
