摘要
1996-03/2003-03纳入强直性脊柱炎合并股骨侧严重骨质疏松的髋关节病变患者17例（24髋）,采用自体骨嵌压植骨结合非骨水泥型全髋关节置换治疗。手术时年龄20～52岁,平均35岁;采用Harris评分方法及X射线片观察进行临床疗效评定。17例患者24髋均获得完整随访,随访时间36～120个月,平均87个月。Harris评分从置换前平均34分提高到置换后平均86.4分,优良率87.5%。X射线片见股骨假体与股骨近段紧密压配;无假体感染及脱位。1髋出现5mm的假体下沉,发生于置换后1年内,经过5年以上随访观察,假体未进一步下沉,并与骨质接触良好,目前无松动表现。提示骨质量对非骨水泥假体置换的疗效影响较大,采用自体骨嵌压植骨技术进行骨质重建,可为强直性脊柱炎合并严重骨质疏松患者全髋关节置换提供了一种良好的解决方法,临床效果满意。
A total of 17 hip joint lesion patients （24 hips） combined with ankylosing spondylitis and severe osteoporosis from March 1996 to March 2003. They received autologous impaction bone graft and cementless total hip replacement. They were 20 52 years old, averagely 35 years. Harris score and X-ray method were used to evaluate clinical outcomes. A total of 17 patients （24 hips） were followed up for 36 120 months, averagely 87 months. Harris score increased from averagely 34 points （preoperation） to averagely 86.4 points （postoperation）, resulting in an excellent and good rate of 87.5%. Radiograph showed that femoral prosthesis was closely fixed to proximal segment of the femur, without prosthetic infection or dislocation. One hip suffered from 5-mrn prosthetic subsidence within 1 year following replacement, and no further subsidence following over 5-year follow up. The prosthesis showed good contact to sclerotin, without loose. It is suggested that bone mass has great effects on cementless prosthetic replacement. Autologous impaction bone graft for bone remodeling provides a good method for total hip replacement in patients combined with ankylosing spondylitis and severe osteoporosis. The clinical outcome is satisfactory.
