Experimental and finite element analysis of surgical drill bits with and without irrigation channel – A case study approach

Drilling is a highly utilized procedure in bone and joint surgery interventions. During this process, an extensive amount of heat can be generated due to the friction between the drill bit and cortical bone. More friction results in higher cutting forces and bone temperatures which can potentially cause irreversible bone tissue damage or osteonecrosis. In order to avoid thermal osteonecrosis and to ensure fast and successful postoperative healing, a surgeon must maintain the bone temperature in the drilling zone below its upper limit.
