The callotasis technique of De Bastiani was used to perform 11 lower extremity lengthenings in ten pediatric and adolescent patients (aged 8.1-18 years). Average gain in length was 5.0 cm per segment (15% of original bone length). All lengthened segments healed without bone grafting or internal fixation. Healing index was 32 days per centimeter gained. The device was well tolerated and easily removed in the clinic setting. There were 13 minor complications, managed without hospitalization. Three angular deformities required manipulation under anesthesia. One angular deformity remains uncorrected, and one patient lacked 1.1 cm of achieving the desired length. All other patients gained the desired length. There were no refractures, deep infections, or other complications. Limb lengthening by the De Bastiani method is a satisfactory procedure for the pediatric and adolescent patient with moderate limb-length discrepancy.
采用德巴斯蒂亚尼（De Bastiani）的骨痂延长技术，对10例儿科和青少年患者（年龄8.1 - 18岁）的下肢进行了11次延长。每节段平均延长长度为5.0厘米（占原始骨长度的15%）。所有延长节段均未进行植骨或内固定而愈合。愈合指数为每延长1厘米需32天。该装置耐受性良好，在门诊环境中易于取出。有13例轻微并发症，无需住院治疗。3例角形畸形需要在麻醉下进行手法矫正。1例角形畸形仍未矫正，1例患者距达到预期长度还差1.1厘米。所有其他患者均达到了预期长度。未发生再骨折、深部感染或其他并发症。对于有中度肢体长度差异的儿科和青少年患者，采用德巴斯蒂亚尼方法进行肢体延长是一种令人满意的手术。
