弹性钉固定分次矫正小腿重度旋转畸形(附11例报告)

Two-stages Correction of Severe Leg Rotational Deformity(A Report of 11 Cases)

本文报告11例儿麻后道症小腿重度外旋畸形患者,其中男7例,女4例。年龄18～25岁,平均22岁。小腿外旋畸形60～70°8例,70°以上3例。采用小腿上端截骨双矩型弹性钉内固定,分次矫正的疗法进行治疗,收到良好效果,避免了一次矫正畸形所引起的神经、血管损伤并发症。本文还讨论了弹性钉的选择,弹性钉固定力学原理及神经、血管损伤机制。

Severe leg rotational deformity after poliomyelitis was treated by two-stages correction method, including a rotational osteotomy of upper leg with a flexible intramedullary nailing to correct rotational deformity not over 50 degrees, and an additional manipulative correction of residual deformity after retire of surgical reaction, usually at 1—2 weeks later. There were 11 patients, 7 men and 4 women, aged from 18—25 years, with 60—70 degrees rotational deformity in 8 cases and over 70 degrees in 8 cases. Result of 6—28 months follow-up study showed a satisfactory correction of deformity, without delay-union and no vessel and nerve complication, which is the main advantage of this method.
