Representation of the possibilities of callus distraction for bridging bone defects on the basis of four typical cases successfully treated with this procedure.
The filling of large diaphyseal bone defects through the use of callus distraction is reliable, relatively simple to carry out, and in most cases can be done on an outpatient basis. After prior osteotomy, a segment of the remaining bone is forced, millimeterwise, into the defect zone. As a result of continuous distraction of the callus forning in the osteotomy, tubular bone with weight-bearing capability is formed, and the patient is spared the defect resulting at the donor site when an autologous bone graft is taken, or the implantation of exogenous material. The same principle is employed for leg lengthening, and also permits simultaneous compensation of axis malalignment.
基于4例成功采用该方法治疗的典型病例，阐述骨痂牵张术修复骨缺损的可能性。
通过骨痂牵张术填充大段骨干骨缺损可靠且操作相对简单，多数情况下可在门诊完成。先行截骨术后，将剩余骨段逐毫米地推进缺损区。由于截骨处形成的骨痂持续牵张，形成了具有负重能力的管状骨，避免了取自体骨时供区出现缺损或植入外源材料。同样原理也用于肢体延长，还可同时矫正轴线排列不齐。
