Dual Mobility Total Hip Replacement

Dual Mobility Components In Total Hip Replacement Youtube A hip replacement implant is a ball in socket mechanism, designed to simulate a human hip joint. typical components include a stem that inserts into the femur (thighbone), a ball that replaces the round head of the thigh bone, and a shell that lines the hip socket. compared to a traditional prosthesis for a hip replacement, a dual mobility. Hip instability following total hip arthroplasty (tha) remains a major challenge and is one of the main causes of revision surgery. dual mobility (dm) implants have been introduced to try to overcome this problem. the dm design consists of a small femoral head captive and mobile within a polyethylene liner.

Dual Mobility Components In Total Hip Arthroplasty Recently, there has been increased interest in dual mobility articulations for total hip arthroplasty (tha) to address the issue of hip instability. dual mobility (dm) cups offer increased stability by virtue of their dual articulation resulting in larger jump distance and greater range of motion before impingement. Total hip arthroplasty (tha) is one of the most successful surgical procedures – reducing pain and providing functional improvement. however, tha instability is a disabling condition and remains the most common indication for revision tha. to combat the risk of instability, the concept of dual mobility (dm) was developed. Dual mobility (dm) total hip arthroplasty (tha) combines the stabilization advantage provided by large head articulation with the low friction advantage provided by small head articulation. there is momentum for dm to be used in a wider selection of patients, with some advocating for dm to be the routine primary total hip construct. further investigation is needed to determine whether the use. Dual mobility (dm) has been used in primary total hip arthroplasty recently for their low dislocation rates, low revision rates, and improved patient functional outcomes. we compared 2 dm systems, anatomic dual mobility (adm; stryker, mahwah, nj) and modular dual mobility (mdm; stryker, mahwah, nj), to determine differences in dislocation rates, revision rates, and patient outcome scores.
