MedSpark -Acetabular Shells and Trials

Total Hip Arthroplasty (replacement) or THA is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Such joint replacement orthopedic surgery is generally conducted to relieve arthritis pain or fix severe physical joint damage such as a hip fracture. During a typical THA procedure, the acetabulum (hip socket) is resurfaced in preparation to receive the outer shell (typically titanium) of the implant system`s cup. During the selection of the acetabular shell, trial shell and liner sizes are evaluated by the surgeon to determine the size that produces the most reliable fit for the patient. Once the proper shell size has been selected, the insert component is placed into the implanted shell component in preparation to receive the femoral head component previously attached to the femoral stem located in the patient`s femur.
