Thermal Osteonecrosis of the Rib after Radiofrequency Ablation in the Thorax
Journal of Vascular and Interventional Radiology, 2008A patient underwent radiofrequency (RF) ablation of a pleural-based pulmonary metastasis from treated hepatocellular carcinoma. Ten months after the procedure, computed tomography and positron emission tomography findings raised the concern of tumor recurrence with invasion of the chest wall, for which the patient underwent thoracotomy with resection ...

Thermal Osteonecrosis Complicating Steinmann Pin Insertion in Plastic Surgery
Plastic and Reconstructive Surgery, 1983Two typical cases of thermal osteonecrosis due to Steinmann pin insertion are presented. Using proper technique, including predrilling or the use of a hand drill, can eliminate the high morbidity problem.

JBJS Case Connector, 2023
Case: We present a case of a female athlete who sustained a nonunion of a tibial stress fracture and was treated with intramedullary nailing (IMN). The patient developed osteomyelitis likely secondary to a thermal osteonecrosis during the index procedure and required resection of the necrotic tibia and bone transport using the ...

Drilling of bone: Effect of drill bit geometries on thermal osteonecrosis risk regions
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2018Bone-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 better understanding on the influences of the point angle, helix angle and web thickness of the drill bit.

Journal of Thermophysics and Heat Transfer, 2008
Many current bone cements have proprietary minor ingredients that affect the chemical kinetics and heat transfer modeling of the exothermic reaction during bone cement polymerization. The geometry and the method of cooling or curing the bone cement can vary by application. We applied a complete numerical model using finite volume methods to investigate

Numerical studies were performed to investigate bone cement polymerization, temperature history and thermal osteonecrosis in cemented hip replacements with finite element methods. In this paper, the effects of pre-cooling and pre-heating of the prosthesis and/or the cement prior to implantation were simulated.

Thermal osteonecrosis during drilling with two-step drills and internally cooled drills
2011Svrha rada. Bušenje kosti uzrokuje porast temperature, a temperatura iznad kriticne od 47oC dovodi do termicke nekroze kosti. Temperature iznad kriticne izražene su uporabom svrdla promjera 4.5 mm bez hladenja. Cilj istraživanja je ispitati utjecaj razlicitih parametara, kao i njihovih interakcija, na porast temperature kosti korištenjem ...
