Internal Fixation in the Treatment of Proximal Femoral Tumor with Reversed Non-contact Bridging Plates

Abstract：Objective To evaluate the treatment efficacy of proximal femoral benign tumor with reversed non-con-tact bridging plates.Methods We retrospectively analyzed the 44 patients who suffered benign tumor in proximal fe-mur and received treatment in the department of orthopaedics of Changhai hospital.After the curettage of tumor lesion and bone grafting,26 patients in Group A received the internal fixation with reversed non-contact bridging plates,while 18 patients in Group B received the external fixation with braces.The adverse events rate,the time of weight loading af-ter operation,and Harris hip scores (one month,three months and half a year after operation respectively)between the two groups were compared.Results There was no loosening or breakage of internal fixation in Group A during the fol-low-up,while one patient in Group B suffered fracture in the bone grafting location.The time of weight loading after op-eration in Group A was shorter than that in Group B,P<0.001.The Harris hip scores of one month and three months after operation in Group A were higher than those in Group B.Differences were statistically significant as the P values were 0.009 and 0.007,respectively.Conclusion Reversed non-contact bridging plates have a good result in the treat-ment of the proximal femoral benign tumor.The plate helps to shorten the time before weight loading after operation and promote the functional recovery of hip
