Abstract
Objective To search for a better internal fixation method in the treatment of humeral shaft fracture by comparing biomechanics and clinical results of double rectangle intramedullary nail and compressed plate.Methods Fracture models were produced in 12 wet humeral bones specimens of adult cadavers.The models were randomly divided into two groups.Three bones of each group were fixed with double rectangle intramedullary and other three bones of each group were fixed with compressed plate.Three point bending test,twisting test and stretching test were done and analysed.Results The results of bending test and torsion test revealed that the double rectangle intramedullary nail was better than the compressed plate for the fixation of humeral shaft fracture.However,in strething test,the two fixation methods showed no significant difference.Conclusion The rectangle intramedullary nail is more suitable than compressed plate for the treatment of humeral shaft fracture.关键词
