Abstract:

Objective    To explore the short-term effects of the stemless hip prosthesis replacement on treating middle and young-aged patients with femoral head necrosis.   Methods   19 cases (middle or young-aged) suffered from femoral head necrosis received the stemless hip replacement surgery, and followed by the evaluation of clinical effects.    Results    The follow up time was about 6 to 65 months. All patients recovered, with the Harris score of 89.4± 6.5 points averagely ( excellent in 13 cases, good in 5 cases, medium in 1 case). Excellent and good rate was about 94.7%.   Conclusions    The stemless hip arthroplasty is suitable for treating middle and young-aged patients with avascular necrosis, for its excellent short-term curative effects. However, the long-term effects need to be revealed.
