RESUMO
Objective To investigate different surgical treatments for femoral intertrochateric fractures. To evaluate the results of treatment of intertrochateric fractures with PFNA. Methods 37 patients with femoral intertrochateric fracture were retrospectively reviewed,of which 12 patients were treated operatively with PFNA,25 patients were treated operatively with DHS. Therapeutic efficacy were compared and analyzed. Results All the patients were followed up for 5-18 months(an average of 11 months). All fractures healed in a mean of 3 months. According to Harris'standard of hip-joint fuction,the outcome was classified into excellent,good and poor. In 25 patients with DHS,the good clinical results was 21 cases. In 12 patients with PFNA, excellent and good clinical result was 11 cases. Conclusion PFNAintemal fixation was an effective method for treating the femoral intertrochateric fractures and better than that by DHS.
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.
