Seventeen patients were reviewed after callotasis lengthening for congenital limb length discrepancy. The average age at lengthening was 10.8 years. Length discrepancy before lengthening ranged from 4.5 cm to 12 cm for the leg, and 24 mm to 30 mm for the forearm. At completion of the lengthening process, all but one patient had their discrepancy corrected successfully. The difficulties encountered were classified into problems, obstacles and complications. All patients suffered from superficial infection, but in only one case did this become a complication, resulting in a residual femoral discrepancy of 2 cm. Of the other three patients who suffered a complication, one fractured through the newly formed bone. The fracture was treated conservatively. In two further femoral lengthenings, the fixator had to be exchanged under general anaesthesia because it had reached its maximum excursion. Callotasis appears to be a safe and reliable method for correcting congenital limb length discrepancy in children.
对17例因先天性肢体长度差异行骨痂延长术的患者进行了回顾性研究。延长时的平均年龄为10.8岁。延长术前腿部长度差异为4.5厘米至12厘米，前臂为24毫米至30毫米。在延长过程结束时，除1例患者外，所有患者的差异均得到成功矫正。所遇到的困难分为问题、障碍和并发症。所有患者均发生浅表感染，但仅1例发展为并发症，导致股骨残留差异2厘米。在另外3例发生并发症的患者中，1例在新形成的骨处发生骨折，骨折采用保守治疗。在另外2例股骨延长术中，由于固定器已达到最大行程，不得不在全身麻醉下更换固定器。骨痂延长术似乎是一种安全可靠的方法，用于矫正儿童先天性肢体长度差异。
