Abstract:

Dislocation after total hip arthroplasty remains a primary concern among orthopaedic surgeons. Endeavors to decrease the incidence of dislocation, while maintaining limb function and mobility, have been painstakingly undertaken. Since their advent in the 1970s, dual mobility cups have proven again and again to be effective in reducing dislocation following total hip arthroplasty. The dual mobility cup enables the surgeon to treat patients with an increased risk for dislocation, while maintaining hip stability, favorable wear properties, and an acceptable rate of dislocation. Disadvantages are related to the potential increased wear and surgeon error. With advances in engineering and design, dual mobility cups have proven useful in providing lower dislocation rates for several pathological conditions. As a result, dual mobility cups have moved into the forefront of total hip arthroplasty.
