title: [Evaluation and treatment of prosthetic hip dislocation].
abstract: Hip dislocation is the second most common complication of total hip arthroplasty followed by aseptic loosening, is the second most common complication of THA presenting with an incidence of 2.4-3.9% in primary procedures and an incidence of up to 28% in revision surgeries. The hip dislocations can be classified into 3 groups: Early, middle and late. Generally early dislocations respond favorably to nonsurgical treatment and have low recurrence rate. In this case the need for revision surgery is much higher. The diagnosis of a dislocated hip is relatively easy to perform because the clinical picture is very typical. Having identified a dislocated hip the first step is to make an attempt to reduce a closed manner. Among the options are the following: Change of modular components, trochanteric progress, review of component orientation and ultimately the use of constrained components. One of the most common problems for which the patient presents early recurrent instability is inadequate orientation of the prosthetic components. The THA is one of the most useful and most successful surgeries the last 100 years, however requires a refined surgical technique, proper patient selection and planning to meet the expectations of it. It currently has a range of possible treatments for problem resolution, with the intent of restoring a stable and functional hip.
