目的探讨和总结利用轨道外固定支架进行尺骨延长治疗骨干续连症中前臂畸形的临床经验。方法回顾性分析2002年8月至2012年12月,我院收治的具有完整资料的25例骨干续连症前臂畸形病例,男9例,女16例,年龄5~11岁,平均7.3岁,均采用尺骨截骨结合轨道外固定支架延长方法治疗。临床疗效根据肌肉骨骼肿瘤学会修改的功能评估量表评定。结果本组随访时间18~96个月,平均30.2个月。尺骨延长长度15~40 mm,平均28 mm,愈合时间3.5~8个月,平均5.2个月。根据肌肉骨骼肿瘤学会修改的功能评估量表进行评定,25例中优11例,良12例,可2例。结论利用轨道外固定支架及尺骨截骨延长治疗骨干续连症的前臂畸形,是一种安全有效的方法,能在不增加新的创伤情况下自动复位桡骨头,同时改善儿童肘关节屈伸、腕关节屈伸和尺桡偏活动及前臂旋转活动功能。
Objective To discuss and summarize the clinical experience of using ulnar extension with orbital external fixation for the treatment of forearm deformity in the treatment of cadiosis. Methods From August 2002 to December 2012, 25 cases of complete forearm deformity with complete data from August 2002 to December 2012 in our hospital were retrospectively analyzed. There were 9 males and 16 females, aged from 5 to 11 years (mean, 7.3 years) All ulnar osteotomy combined with orbital external fixator extension method. Clinical efficacy was assessed according to a functional assessment scale modified by Musculoskeletal Oncology Society. Results The follow-up time ranged from 18 to 96 months with an average of 30.2 months. Ulna extension length of 15 ~ 40 mm, an average of 28 mm, healing time 3.5 to 8 months, an average of 5.2 months. According to the musculoskeletal tumor society to modify the functional assessment scale for evaluation, 25 cases of excellent in 11 cases, good in 12 cases, 2 cases. Conclusion The use of orbital external fixator and ulnar osteotomy for the treatment of forearm deformity of the backbone continous disease is a safe and effective method to automatically reposition the radial head without adding new traumatic injuries and to improve the elbow flexion and extension, Joint flexion and extension and radial deviation activities and forearm rotation activities.
