OBJECTIVE: to probe into the mechanism of extracorporeal shock wave in treatment of nonunion and delayed union of bone fracture and the existed unsolved problems in the clinical study.
目的：探讨体外冲击波在治疗骨折不愈合和延迟愈合的机制以及临床研究中存在的问题。
The radiographs displayed well formed atrophic non union. In Group B, after 6 weeks, all rabbits were found that fracture healing was delayed, with some also having deformity.
组中所有动物在6周内截骨端出现延迟愈合，部分伴有畸形，骨断端有大量肥大骨痂形成。
In the fresh fracture group, no delayed union or nonunion was observed, and the solid bone healing time averaged 2.3 months.
无骨折延迟愈合或骨不连患者，骨牢固愈合时间平均为2.3个月。
Conclusion the use of three pace bone-setting manipulation restoring ulna and radius benifited functional recovery and reduced the rate of fracture delayed-union and nonunion.
结论三步正骨手法治疗尺桡骨中、下段双骨折有骨折愈合时间短，功能恢复快等优点，并能减少骨折延迟愈合和不愈合等并发症。
The mean follow- up period was 13 months, and 2 fractures were mat-union, 1 fracture were delayed- union. 1 fracture had a stiff knee.
平均随访13个月。2例股骨颈疲劳骨折畸形愈合，1例股骨颈疲劳骨折延迟愈合，1例股骨干疲劳骨折出现膝关节僵直。
The mean follow- up period was 13 months, and 2 fractures were mat-union, 1 fracture were delayed- union. 1 fracture had a stiff knee.
