Indications for Total Hip Arthroplasty
a. Originally, the primary indication for total hip arthroplasty was the alleviation of incapacitating arthritic pain in patients older than 65 years whose pain could not be relieved sufficiently by nonsurgical means and for whom the only surgical alternative was resection of the hip joint (Girdlestone resection arthroplasty).
b. Of secondary importance was the improved function of the hip. After the operation had been documented to be remarkably successful, the indications were expanded to include the other disorders.
i. “THR [total hip replacement] is an option for nearly all patients with diseases of the hip that cause chronic discomfort and significant functional impairment.”
ii. Total hip replacement includes femoral and acetabular components. Both the components can be placed with or without cement. The weakest link in THR is bone cement interface. Commonest combination that is used is metallic femoral component (chromium cobalt alloy) and highly cross linked polyethylene acetabular component.
