Simultaneous bilateral total hip arthroplasties in nonagenarians.

Total hip arthroplasty (THA) is an effective and durable treatment option for hip osteoarthritis (OA). As life expectancy continues to increase, so too will the demand for joint arthroplasty in the 10th decade of life, frequently in cases involving osteoarthritis of both hips. Simultaneous bilateral total hip arthroplasty (SBTHA) is a valuable therapeutic option in appropriately selected patients with bilateral degenerative hip disease, although its use in the very elderly is poorly reported on in the literature. A case of bilateral hip OA successfully treated with SBTHA in a nonagenarian is presented and the literature is reviewed.
