摘要:

背景:目前普遍认为非骨水泥型假体适用于年龄< 65岁的患者,骨水泥假体适用高龄、骨质情况欠佳的患者。但没有明确证据表明非骨水泥假体不适用于年龄> 70岁、既往身体健康、日常活动量满意、无骨质疏松或有轻度骨质疏松的患者。
目的:观察非骨水泥型髋关节假体用于老龄初次全髋关节置换患者的效果。
方法:纳入行非骨水泥假体初次全髋关节置换、年龄> 70岁的老龄患者57例65髋,平均年龄86.3岁;其中股骨颈骨折33例33髋,股骨头缺血性坏死18例25髋,髋关节发育不良6例7髋。记录置换时间、手术出血量、住院时间、置换后初次下床活动的时间、置换前及置换后3,6,12,24个月的髋关节Harris评分、X射线片结果、置换后并发症。
结果与结论:随访6~40个月,平均19.6个月。53例完成随访,4例失访,未发现假体松动和需翻修手术病例。Harris评分由置换前的平均(40.7±18.9)分提高到置换后的(89.2±5.5)分,优良率为93.7%。置换后并发症包括术口血肿1例、脑血管意外1例几泌尿系感染1例。提示老龄患者用非骨水泥型髋关节假体行初次全髋关节置换治疗能达到满意的近期效果。

Abstract:

BACKGROUND: Non-cemented prosthesis is commonly considered applicable for patients < 65 years, and cemented prosthesis for elderly patients with poor bone condition. However, there is no evidence that non-cemented prosthesis cannot be used for patients aged > 70 years, who are healthy, able to do daily activity, with no osteoporosis or with mild osteoporosis.

OBJECTIVE: To evaluate the clinical effect of premiere non-cemented total hip arthroplasty in elderly patients.

METHODS: A total of 57 cases (65 hips) of elderly patients, aged > 70 years, with an average age of 86.3 years, underwent primary total hip arthroplasty with non-cemented prosthesis, including 33 cases (33 hips) of femoral neck fractures, 18 cases  (25 hips) of femoral head avascular necrosis, and 6 cases (7 hips) of developmental dysplasia of hip. The operation time, blood loss, hospitalization time, beginning time of getting out of bed postoperation, Harris score, X-ray result, complications in 3, 6, 12 and 24 months postoperatively.

RESULTS AND CONCLUSION: The follow-up time ranged from 6 to 40 months postoperation, with an average time of 19.6 months. A total of 53 patients were followed up and 4 cases were lost after 1 year postoperatively. No prosthesis loosening was observed, and no cases required reoperation. Harris score was increased from average 40.7±18.9 preoperatively to 89.2 ±5.5 postoperatively, with an excellent and good rate of 93.7%. Wound hematoma, cerebral vascular accident and urinary tract infection were respectively observed in 1 case. Elderly patients treated with non-cemented prosthesis in primary total hip arthroplasty obtained satisfactory short-term clinical outcomes.
