Total hip arthroplasty (THA) with the use of a Mega prosthesis was a successful surgical procedure in the management of tumors of the hip as well as in revision THA with loss of bone stock. Passive hip motion and strength of hip muscles, walking ability, and activities of daily living in nine such cases compared well with the function following conventional THA. Limp and positive Trendelenburg sign were more common after Mega THA. Dislocation of the prosthesis occurred in 2/14 cases. Fracture of the femoral condyle occurred in one case. Another case had stem fatigue failure of a thin stem.
使用巨型假体进行全髋关节置换术（THA）在治疗髋关节肿瘤以及骨量丢失的翻修THA方面是一种成功的外科手术。9例此类病例的髋关节被动活动度、髋部肌肉力量、行走能力和日常生活活动能力与传统THA后的功能相比良好。巨型THA后跛行和阳性特伦德伦伯格征更为常见。14例中有2例发生假体脱位。1例发生股骨髁骨折。另1例出现细柄的柄部疲劳失效。
