目的：探讨计算机导航技术在儿童骨桥切除手术中的作用。方法2008年8月至2011年3月，对北京积水潭医院小儿骨科42例外伤后导致畸形的儿童应用三维CT导航技术进行骨桥切除，治疗骺板部分早闭造成的下肢畸形。男26例，女16例，平均年龄9.8（5.0～13.0）岁。结果6例患儿失访，剩余36例平均随访25（15～44）个月。其中畸形完全矫正的13例，15例畸形有所改善，但尚未完全矫正。平均矫正畸形角度为14°（8°～25°）。结论计算机导航技术提高了儿童骺早闭骨桥切除手术的精确性和安全性。

Objective To report our experience of using image-guided computer navigation for bone bridge resection in children.Methods Between August 2008 and March 2011 at our hospital , computed tomography ( CT )-based navigation system for bone bridge resection was used in 42 children with lower extremity deformities due to partial physeal growth arrest.There were 26 males and 16 females with an average age of 9.8 (5.0-13.0) years.Results Six patients were lost to follow-up.In other 36 patients, the average duration of radiographic and clinical follow-up was 25 (15-44) months.Among them, 13 were corrected to neutral while 15 had insufficient correction.The average correction angle of deformities was 14 (8-25) degrees.Conclusion The image-guided computer navigation system enhances the accuracy and safety of bone bridge resection in children.
