Cortical bone drilling and thermal osteonecrosis [PDF]

open access: possibleClinical Biomechanics, 2012
Bone drilling is a common step in operative fracture treatment and reconstructive surgery. During drilling elevated bone temperature is generated. Temperatures above 47°C cause thermal osteonecrosis which contributes to screw loosening and subsequently implant failures and refractures.The current literature on bone drilling and thermal osteonecrosis is

Drilling of bone: thermal osteonecrosis regions induced by drilling parameters

Biomedical Physics and Engineering Express, 2019
Abstract In bone-drilling research, thermal osteonecrosis regions have only begun to be investigated. This study evaluates the thermal osteonecrosis regions and bone temperature elevations induced by drilling parameters in drilling of human cortical bone.

Focal cryogen insults for inducing segmental osteonecrosis: computational and experimental assessments of thermal fields

Journal of Biomechanics, 2003
Orthopaedic management of femoral head osteonecrosis is a common clinical problem for which there presently is no good solution. Current animal models are inappropriate to study potential new solutions, since it has been difficult to replicate the natural history of structural collapse seen in the human disorder.

Thermal damage potential during hip resurfacing in osteonecrosis of the femoral head: An experimental study

Journal of Orthopaedic Research, 2008
AbstractHip resurfacing arthroplasty has become an attractive treatment option for young, active patients with femoral head necrosis. However, little information is available about the potential thermal damage to the remaining femoral head when a cemented component is used.

Fast & Injurious: Reducing thermal osteonecrosis regions in the drilling of human bone with multi-objective optimization

Measurement: Journal of the International Measurement Confederation, 2020
Abstract Excessive heat generated from wrong combinations of bone-drilling parameters could kill the bone cells (thermal osteonecrosis). This paper combines numerical, experimental, and statistical approaches to investigate the induced thermal damages by bone-drilling parameters. Bone-drilling was simulated in the finite element method (FEM) software
