【Abstract】 Objective To understand the regularity of angular deformity correction and prevent the complications of limb lengthening.Methods Twenty -five patients with extremity shortening and angular deformities who underwent limb lengthening operation.The average extent of angular deformities was 17° (range, 5° to 32°).Results All patients were followed-up for 2-12 years ( average, 7.4years )with satisfactory results.The degree of angular correction to maximum was 32°.Conclusion Reconstruction of the axial line by osteotomy is a simple,easy and effective method.

肢体延长所采用的延长工具主要分为一侧单杆外固定和环形Ilizarov外固定架。两者的主要区别在于前者单纯应用于延长，易于接受，但难以矫正成角。而后者可以克服这一弊端，不但能够达到延长的目的，而且可以矫正旋转、横移及成角,尤其适于膝内外翻同时伴有肢体短缩的患儿。尽管目前肢体延长的疗效已获肯定，但肢体延长中术前、术中成角畸形如何矫正，问题仍然不少，有待进一步完善提高，本文就此报告如下,以便借鉴。
