DESIGN AND ANALYSIS OF FEMORAL NAIL EXTRACTION INSTRUMENT FOR HUMAN FEMUR BONE

Different conventional techniques have been noticed to remove intramedullary femur distal nail, a simple method is explained to remove a broken distal closed section intramedullary nail with nail extraction instrument. The surgical technique is described. This technique reduces physical torture of patient during surgery and headache of doctors. In this article the design procedure for nail extraction instrument is explained as well as analysis results (in ANSYS) of nail extraction instrument are discussed. This technique involves removal of distal broken femur nail by on the spot creating threads in the nail, which is one of the feasible technique & the results of this analysis are helpful for orthopedic surgeons for clinical interest
