Thermal osteonecrosis and bone drilling parameters revisited [PDF]

Archives of Orthopaedic and Trauma Surgery, 2007
INTRODUCTION: During the drilling of the bone, the temperature could increase above 47 degrees C and cause irreversible osteonecrosis. The result is weakened contact of implants with bone and possible loss of rigid fixation.

Osteonecrosis with the use of polymethylmethacrylate cement for hip replacement: thermal-induced damage evidenced in vivo by decreased osteocyte viability [PDF]

European Cells & Materials, 2014
Thermal damage to host bone is a possible source of compromise of fixation in patients undergoing cemented total hip replacement (THR). Data on the subject to date are derived from mathematical modelling powered by animal studies.

Thermal Osteonecrosis Caused by Bone Drilling in Orthopedic Surgery: A Literature Review [PDF]

Cureus, 2019
Thermal osteonecrosis is the in situ death of bone tissue as a result of excessively high temperatures. While the exact temperature at which thermal osteonecrosis occurs has not yet been determined, 50°C is the accepted critical value, as bone regeneration is almost completely impaired from this point on.

Cortical bone drilling and thermal osteonecrosis [PDF]

Clinical 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

Preventing thermal osteonecrosis through 3D printed ceramic grinding tool

Additive Manufacturing, 2023
Conventional grinding tools in orthopedic surgery and neurosurgery are solid in structure, leading to a limited amount of coolant that can reach the bone surgery zone, and therefore causing localized high-temperature-induced issues (infection, necrosis ...

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

Measurement, 2020
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 ...

Local heat generation during screw insertion into diaphyseal bone: a biomechanical study on different conditions (e.g. screw type, material, mode of insertion)

BMC Musculoskeletal Disorders, 2021
Background The implantation of screws is a standard procedure in musculoskeletal surgery. Heat can induce thermal osteonecrosis, damage the bone and lead to secondary problems like implant loosening and secondary fractures.

Drilling of bone: Effect of drill bit geometries on thermal osteonecrosis risk regions [PDF]

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2019
Bone-drilling operation necessitates an accurate and efficient surgical drill bit to minimize thermal damage to the bone. This article provides a methodology for predicting the bone temperature elevation during surgical bone drilling and to gain a ...
