Abstract
Orthopaedic bone cutting processes such as osteotomy and hip arthroplasty involve the cutting of one with the aid of various manual and powered cutting instruments including manual and powered bone saws. The extent of surgically induced bone necrosis at the point of the cutting tool and the bone is mainly due to the frictional heat generated by bone cutting. Bone necrosis has an impact on bone regeneration, and the rate of healing of the bone post operation. The threshold temperature for impaired regeneration of bone is in the range of 44°C to 47°C. Overheating also affects the sharpness life of the blade. A review of the literature indicates that work has been completed on temperature in the immediate cutting zone. This current research focuses on the size of the overheated zone relative to the cutting position and effect of blade sharpness and cutting parameters such as cutting forces and rate of cutting on the size of the affected zone.
