Simulated comparing experiment for Borden osteotomy with modified Borden osteotomy

OBJECTIVE To verify the stability of two different methods of Borden osteotomy. METHODS Using the left and right femora and simulated hip and knee joints in 4 sets of adult ptoma, the Borden osteotomy with two fixed methods were performed under two side of the big tuberosity. The broken four sites of left femur were fixed with L save plate and one of right femur were fixed with straight palate, and the stability was tested on the SLW 10 type Biomechanical Universal Tester. RESULTS The method fixed with straight plate by the modified Borden osteotomy had better stability than that with L save plate. CONCLUSION The modified Borden osteotomy simplified the operation and improved the stability.
