To explore the efficacy of callus distraction performed by external fixtor in the reconstruction of bone defect and leg shortening of femur after osteomyelitis.
Nineteen child patients with bone defect and leg shortening after ostemomyelitis were treated by callus distraction with external fixator. The mean length of the bone defect was 1.3 cm. The mean leg-length discrepancy was 4.8 cm.
All patients were followed up for 21-82 months. The bone lengthening area grew well, the length of callus distraction was 4.5-8.0 cm, and the mean radiographic consolidation index was 39.7 d/cm. According to the Paley's criteria, the healing effect of 14 cases was excellent, and that of the rest 5 cases was good. The functional recovery of 11 cases was excellent, and that of the rest 8 cases was good.
Callus distraction is a reliable method in the reconstruction of bone defect and leg shortening caused by ostemomyelitis.
探讨外固定器行骨痂牵张术在骨髓炎后股骨骨缺损及肢体短缩重建中的疗效。
19例骨髓炎后骨缺损及肢体短缩患儿采用外固定器行骨痂牵张术治疗。骨缺损平均长度为1.3cm。肢体长度差异平均为4.8cm。
所有患者均随访21 - 82个月。骨延长区生长良好，骨痂牵张长度为4.5 - 8.0cm，平均影像学愈合指数为39.7d/cm。根据Paley标准，14例愈合效果为优，其余5例为良。11例功能恢复为优，其余8例为良。
骨痂牵张术是重建骨髓炎所致骨缺损及肢体短缩的可靠方法。
