Over a four year period, 20 segments in 16 patients were treated by lengthening by callotasis or chondrodiastasis. The indications for treatment were leg length discrepancy in 13 patients and short stature in three. Patients with leg length discrepancy were all treated by femoral lengthening; the mean length gained was 4.4 cm (range 2.5 to 6.Ocm). For patients with short stature, the mean femoral length gain was 10.0 cm (9.0 to 10.5 cm), and the mean tibial length gain was 8.0 cm (6.5 to 9.0 cm). The commonest problem was pin tract infection, but this always settled with antibiotic therapy. Most other complications were also successfully dealt with, and did not compromise the outcome of treatment. At the time of review, 13 of the 16 patients said they were very happy with the result; two patients were reserving judgement until completion of treatment, and, only one thought the treatment had been of no benefit. Our initial experience, with callotasis in particular, has been that it is a highly satisfactory method of limb lengthening, has an acceptable complication rate, and involves minimal hospitalization as compared with older techniques.
在四年期间，对16例患者的20个节段采用骨痂延长术或软骨扩张延长术进行治疗。治疗指征为13例患者存在下肢长度不等，3例患者身材矮小。下肢长度不等的患者均采用股骨延长术；平均延长长度为4.4厘米（范围2.5至6.0厘米）。对于身材矮小的患者，股骨平均延长长度为10.0厘米（9.0至10.5厘米），胫骨平均延长长度为8.0厘米（6.5至9.0厘米）。最常见的问题是针道感染，但通过抗生素治疗总能得到解决。大多数其他并发症也得到了成功处理，并未影响治疗结果。在复查时，16例患者中有13例表示对结果非常满意；2例患者在治疗完成前保留意见，只有1例认为治疗没有益处。我们最初的经验，尤其是骨痂延长术的经验是，它是一种非常令人满意的肢体延长方法，并发症发生率可以接受，与旧技术相比住院时间最短。
