Assessment of Thermal Osteonecrosis during Bone Drilling Using a Three-Dimensional Finite Element Model [PDF]
BioengineeringBone drilling is a common procedure used to create pilot holes for inserting screws to secure implants for fracture fixation. However, this process can increase bone temperature and the excessive heat can lead to cell death and thermal osteonecrosis ...

Effect of thermal osteonecrosis around implants in the rat tibia: numerical and histomorphometric results in context of implant removal [PDF]
Scientific Reports, 2022 The purpose of this rat study was to explore the feasibility of in vivo temperature thresholds affecting bone contact at the implant surface. Based on these data, thermal necrosis should be used for implant removal in the subsequent in vivo study.

Thermal Management of Bone Drilling Based on Rotating Heat Pipe
Energies, 2021 Bone drilling is a common surgical operation, which often causes an increase in bone temperature. A temperature above 47 °C for 60 s is the critical temperature that can be allowed in bone drilling because of thermal bone osteonecrosis.

Experimental temperature evaluation during a robotized bone drilling process
Biotechnology & Biotechnological Equipment, 2023 A serious problem associated with orthopedic bone drilling manipulation is the so-called thermal osteonecrosis (TO). This problem occurs because the drilling manipulation generates heat, and the amount of heat depends on the drilling conditions.
