Distraction osteogenesis was used to correct congenital hand deformities in 12 digits. The patients' ages at the time of distraction ranged between 2.5 and 7 years. A total of nine patients underwent lengthening of 12 bones. The average period of distraction was 31.1 +/- 17.6 days. The average length of distraction was 23.6 +/- 7.3 mm. Seventeen percent of the patients after lengthening had an angular deformity that required remodeling of the regenerate. No infections were noted. Distraction osteogenesis provides a useful tool for reliable and predictable correction of osseous defects with vascular bone in patients with congenital anomalies of the hand.
采用牵引成骨术矫正12个手指的先天性手部畸形。牵引时患者年龄在2.5至7岁之间。共有9例患者接受了12根骨头的延长术。平均牵引期为31.1 +/- 17.6天。平均牵引长度为23.6 +/- 7.3毫米。延长术后17%的患者出现成角畸形，需要对再生骨进行重塑。未发现感染情况。牵引成骨术为可靠且可预测地矫正手部先天性异常患者的伴有血管的骨缺损提供了一种有用的工具。
