Abstract：Objective To compare the effect of split interlocking intramedullary nail and locking plate on fracture of humerus of biomechanical.Methods 36 humerus specimens collected from Shandong Medical College from March 2014 to March 2017 were divided into control group(locking plate group)and experiment group(split interlocking intramedullary nail group).Three point bending,axial compression,torsion strength biomechanical,bone healing time,bleeding force,dosage of analgesics and incision length were compared in two groups with statistical software SPSS 17.0.Results The three point bending,axial compression and torsional strength were higher in experiment group than in control group(P ＜ 0.05).Conclusion Clinical bifurcate in humerus fracture internal fixation with interlocking intramedullary nail have superior biomechanical effect,simple operation,intraoperative small trauma,less blood loss,less postoperative analgesia drug dosage,lower internal fixation failure rate,small incision,and the bone healing time is short,the effect of late rehabilitation is good.Interlocking intramedullary nailing mehod may be the first choice of humerus fracture internal fixation.
