全髋关节置换术治疗僵直髋的临床疗效

The clinical efficacy of total hip arthroplasty in the treatment of stiff hip

目的探讨僵直髋患者行全髋关节置换术(THA)的临床疗效。方法采用THA治疗16例僵直髋患者(21髋),比较手术前后髋关节被动屈曲度、Harris评分。结果患者手术均顺利完成。16例患者均获得随访,时间6个月~3年。未出现术后切口感染、脂肪栓塞、下肢静脉血栓、假体松动等并发症。末次随访时,被动屈曲度由术前0°提高至62°~96°(76.5°±8.3°)(P<0.01);Harris评分由术前14~38(27.2±2.8)分提高至67~92(84.1±6.5)分(P<0.01);髋关节功能:优8髋,良9髋,可3髋,差1髋,优良率17/21。结论THA治疗僵直髋,能够减轻髋关节疼痛,增加髋关节活动度,改善髋关节功能,提高患者的生活质量。术前的充分准备及丰富的手术经验是手术成功的关键。

Objective To investigate the clinical efficacy of total hip arthroplasty(THA)in patients with stiff hip.Methods The clinical data of 16 patients with stiff hip(21 hips)were collected,who were undergone THA.The passive range of flexion,Harris score were compared in the preoperation and postoperation.Results All patients underwent successful surgery.All of 16 patients were followed up for 6 months to 3 years,there were no postoperative complications such as incision infection,fat embolism,venous thrombosis of the lower extremities,prosthesis loosening.At the last follow-up,the passive range of flexion increased from 0°preoperatively to 62°~96°(76.5°±8.3°)postoperatively(P<0.01);the Harris score increased from 14~38(27.2±2.8)points preoperatively to 67~92(84.1±6.5)points(P<0.01).The hip function was excellent in 8 hips,good 9 hips,fair 3,poor 1,the excellent and good rate was 17/21.Conclusions THA for the treatment of stiff hip joints can reduce hip pain,increase hip joint mobility,improve hip function and patients′quality of life.However,the adequate preparation before surgery and rich surgical experience are the key to successful operation.
