One-stage total hip arthroplasty and light-bulb procedure for bilateral non-traumatic osteonecrosis of femoral head in different stages

摘要

Clinically, it is not rare for patients with bilateral non-traumatic osteonecrosis of femoral head (NONFH) first presenting to an orthopedic surgeon with one hip that requires total hip arthroplasty (THA) and another asymptomatic or less symptomatic one that potentially needs hip preservation surgery. Theoretically, the to-be-preserved hip should be treated prior to, or at least simultaneously with, the THA side. Yet, some patients may reject treatment of the asymptomatic or less symptomatic side due to their doubt on the necessity of undergoing a surgery or concerning over its safety. We hypothesized that one-stage THA for one hip and contralateral “light-bulb” procedure for the contralateral side can yield benefits for these patients.
