摘要
[目的]探讨外固定支架行骨痂延长治疗儿童股骨化脓性骨髓炎后骨缺损及肢体短缩的疗效。[方法]采用外固定支架对27例儿童(平均12.8岁)股骨化脓性骨髓炎后骨缺损及肢体短缩的患者行骨痂延长术,术前患肢平均骨缺损长度1.2cm(1.0～1.7cm),患肢平均短缩4.3cm(3.0～6.8cm)。[结果]随访30～112个月(平均86个月),骨不连接处全部愈合,骨延长区骨生长满意。骨延长4.0～8.0cm,平均6.1cm,平均外固定指数39.2d/cm(36.8～48.4d/cm)。依据Paley的评定标准,骨愈合情况评定:优21例,良6例;功能评定:优19例,良8例。[结论]外固定支架行骨痂延长是治疗儿童股骨化脓性骨髓炎后骨缺损及肢体短缩的可靠方法。
[ Objective ] To study the effect of reconstruction for bone defect and leg shortening with external fixator. [ Methods] Twenty -seven child patients （ mean age of 12. 8 years ） with bone defect and leg shortening caused by supprative ostemomyelitis were treated by callus distraction performed with external fixator. The mean length of the bone defect was i. 2 cm （ range , 1.0 to 1.7cm） according to radiographic assessment. The mean leg - length discrepancy was 4. 3 cm （ range , 3.0 to 6. 8 cm） . [ Results] Twenty -seven patients were followed -up for a mean of 86 months （range, 30 to 112 months） . All bone were union. The mean radiographic consolidation index was 39. 2 d/cm （ range, 36. 8 to 48.4 days/cm） . [ Conclusion] Callus distraction is a reliable method for reconstructing bone defect and leg shortening caused by supprative ostemomyelitis.
