To explore the efficacy and experience of callus distraction technique with the external fixator for valgus deformity of the knee companied with leg shortening in young patients and to provide evidence for selecting reasonable therapy.
From January 2002 to January 2009, the clinical data of 28 young patients (17 males and 11 females, aged 8 to 14, mean age 11.9 years) treated with callus distraction, who had valgus deformity of the knee, companied with leg shortening, were analyzed retrospectively. Three had bilateral total valgus deformity of the knee, with a total of 31 knees. Before the operation, the abnormal limbs shortened from 3 to 7 cm (average 4.1 cm) companied with the normal one. The tibiofemoral angle ranged from 138° to 160° (mean angle 148°) and the Condyle interval from 5 to 33 cm (mean interval 15.2 cm).
The 28 patients were followed up for 35 to 84 ( mean 62 ) months. The extent length ranged from 4.5 to 10.1 cm (average 6.8 cm). The tibiofemoral angle ranged from 169° to 175° (mean 173°) after the union. The patients resumed the normal length of limbs, and the severe valgus deformity of the knee was corrected.
Callus distraction with external fixator is effective for serious valgus deformity of the knee companied with leg shortening.
探讨采用外固定器行骨痂牵张技术治疗青少年膝关节外翻畸形伴肢体短缩的疗效及经验，为选择合理的治疗方法提供依据。
回顾性分析2002年1月至2009年1月采用骨痂牵张技术治疗的28例青少年膝关节外翻畸形伴肢体短缩患者（男17例，女11例，年龄8～14岁，平均11.9岁）的临床资料。其中3例为双侧膝关节完全外翻畸形，共31个膝关节。术前患侧肢体较健侧短缩3～7cm（平均4.1cm）。胫股角为138°～160°（平均148°），髁间距为5～33cm（平均15.2cm）。
28例患者随访35～84个月（平均62个月）。延长长度为4.5～10.1cm（平均6.8cm）。骨愈合后胫股角为169°～175°（平均173°）。患者肢体恢复正常长度，膝关节重度外翻畸形得到矫正。
外固定器骨痂牵张技术治疗青少年严重膝关节外翻畸形伴肢体短缩疗效确切。
