RESUMO
Objective To investigate the clinical applications of the chain locking-type tension bands. Methods89 cases with patellar bone fractures,27 olecranal fractures patients,18 patients with fractures of surgical neck of humerus,16 patients with dislocation of the acromioclavicular joints and 12 patients with clavicular lateral fractures were treated with chain locking-type tension bands. ResultsTheResultsshowed that all patients wound were postoperative first intention.The healing time of the fractures were 6 ～ 18 months(average 10 months).The Kirschner's pins lapping,steel wire breaks and tension bands out of control were not found. ConclusionCompared with the traditional tension bands,the chain locking-type tension bands had stronger stability,stress distribution more even and less complications.
