The procedure for femoral callotasis is explained, and a series of 160 lengthenings is reviewed, 60 for limb length discrepancy and 100 for short stature. Callotasis was performed in 106 subjects with a mean age of 19 years. The mean healing index (HI) of 36 days per centimeter is related more to etiology than to age or extent of lengthening. There were nine complications (15%) among subjects treated for limb discrepancies and 39 (39%) in those treated for short stature. Three permanent sequelae were recorded: necrosis of the head of the femur (two cases) and permanent extension deficit of the knee (one case). The present review assesses the type of results that can be achieved with callotasis in straightforward cases of femoral lengthening when the guidelines proposed by the author are followed. It does not attempt to compare this technique with other methods of limb lengthening.
本文解释了股骨延长术的操作过程，并回顾了一系列160例延长手术，其中60例用于治疗肢体长度差异，100例用于治疗身材矮小。106名受试者接受了延长术，平均年龄为19岁。平均愈合指数（HI）为每厘米36天，这与病因的关系比与年龄或延长程度的关系更大。治疗肢体长度差异的受试者中有9例并发症（15%），治疗身材矮小的受试者中有39例并发症（39%）。记录到3例永久性后遗症：股骨头坏死（2例）和膝关节永久性伸展障碍（1例）。本综述评估了在遵循作者提出的指导原则的情况下，在简单的股骨延长病例中采用延长术所能取得的结果类型。本文并未尝试将该技术与其他肢体延长方法进行比较。
