【摘要】 目的探讨髌骨骨软骨骨折用可吸收螺钉手术固定方法及其疗效。方法我院2004年6月~2009年12月共收治了14例急性膝关节外伤患者,年龄13~21岁(男3,女11;左膝8例,右膝6例)。经CT检查8例、MRI检查6例确诊髌骨骨软骨骨折。手术发现股骨外髁软骨挫伤及划痕;髌骨内侧松弛,骨软骨骨折。所有患者均采用手术复位及可吸收螺钉固定。术后24小时开始股四头肌收缩训练,外固定保护3周膝关节无负重活动。2~3月CT或X显示骨软骨下骨折块愈合后负重功能锻炼。结果 12例获得4~9年随访,平均6.5年,使用HSS标准评价优11例,良1例。结论髌骨骨软骨骨折早期诊断、手术复位用可吸收螺钉内固定可靠;早期功能锻炼,晚负重行走,疗效良好。更多还原

【Abstract】 Objective To investigate the effect of using absorbable screws in treating acute osteochondral fracture of patella.Methods From June 2004 to December 2009,14 patients with acute knee injury,aged from 13-21 years(3 males and 11 females,8 left knees,6 right knees).Eight cases were confirmed as acute osteochondral fracture of patella by CT imaging,and six cases by MRI.All cases revealed patella subluxation,osteochondral fracture in the rearward medial part and medial retinaculum injuries of patella,.as well as cartilage contusion of condylus lateralis femoris in intraoperative finding.Osteochondral fractures of patella were treated with open reduction and fixation with absorbable screws.Knee joints exercise with contraction of quadriceps muscle began in 24 hours after operation.The patients received external fixation for 3 weeks.Weight bearing walking began in 2-3 months after CT or X-ray showed bone healing.Results Twelve patients were followed with 4-9 years,an average of 6.5 years.According to HSS evaluation,11 cases were excellent,one case was good.Conclusion Early surgical procedure,excellent reduction and fixation with absorbable screws,early active exercise were necessary for the treatment of osteochondral fracture of patellas.更多还原
