The purpose of the study was to examine the reliability with which a specific technique of corrective osteotomy of malunions of the distal radius combined with early mobilisation could both restore the normal anatomic parameters of the radius and achieve a functional range of motion with good strength. Corrective osteotomy of the distal radius was performed through a volar approach using a fixed angle volar plate and cancellous bone graft from the iliac crest in 19 patients of mean age 50 years with initial malunions with a mean dorsal tilt of 36 degrees and 7 mm of ulnar variance. An immediate mobilisation programme was started. All healed at a mean of less than 12 weeks (including two heavy smoking patients who required repeat cancellous bone grafting to achieve final union) to achieve a total arc of wrist motion around 120 degrees, forearm rotation of 158 degrees and grip strength which was 80% of contralateral. This treatment strategy was judged to be straightforward and effective.
本研究的目的是检验一种特定的桡骨远端畸形愈合矫正截骨术结合早期活动的技术，能否恢复桡骨的正常解剖参数并实现具有良好力量的功能性活动范围。对19例平均年龄50岁的患者采用掌侧入路，使用锁定掌侧钢板及取自髂嵴的松质骨移植进行桡骨远端矫正截骨术，这些患者最初存在畸形愈合，平均背侧倾斜36度，尺骨变异7mm。术后立即开始活动计划。所有患者平均在不到12周时愈合（包括两名重度吸烟患者，他们需要再次进行松质骨移植才能实现最终愈合），腕关节总活动弧度约为120度，前臂旋转158度，握力为对侧的80%。这种治疗策略被认为简单有效。
