Thermally Induced Bone Necrosis in Rabbits

Clinical Orthopaedics and Related Research, 1984
The exposure of bone to high temperatures has become quite common, especially with the increasing use of polymethylmethacrylate (PMMA) bone cement. With particular regard to total hip arthroplasty, many authors have commented on the temperature problem induced by the curing PMMA cement mass. Polymerization temperatures at the bone-cement interface have

An investigation on thermal necrosis during bone drilling

International Journal of Machining and Machinability of Materials, 2016
Drilling through bone is an old and effective method to get rapid cure from bone injury. During orthopaedic surgery we must need to fix the bones at their appropriate position so that it can rehabilitate at its natural position. Bone needs to be fixed with implants and screws for this overall curing process and drilling through bone is a necessary ...

Ischemic Necrosis of the Intrinsic Muscles of the Hand after Thermal Injuries

The Journal of Bone & Joint Surgery, 1974
In twenty-nine consecutive autopsies after burns that involved an average of 61 per cent of the body surface, 62 per cent of the histological sections of the intrinsic muscles of both hands showed patchy or total destruction of the muscles in one or more intrinsic compartments.

Heat Generation in Bone Cutting-Implications for Thermal Necrosis

Advances in Heat and Mass Transfer in Biotechnology, 2001
Abstract A bunion is a common foot disorder caused by an abnormal outward projection of the joint and inward turning of the toe. Surgery to correct the malformation involves cutting the first metatarsal head, repositioning and setting it; the bone is then left to heal itself over time. A potentially serious by-product of the bone cutting

Thermally induced myocardial preservation and necrosis in deprived fetal mouse hearts

American Journal of Physiology-Heart and Circulatory Physiology, 1977
Cultured fetal mouse hearts deprived of oxygen and glucose were used to examine the effect of temperature on the mechanical, biochemical, and ultrastructural responses of the deprived myocardium to assess the utility of this in vitro model for studying myocardial necrosis, preservation, and repair.

Numerical simulation of thermal bone necrosis during cementation of femoral prostheses

Journal of Mathematical Biology, 1991
The implant of a femoral prosthesis is a critical process because of the relatively high temperature values reached at the bone/cement interface during the cementation of the infibulum. In fact, the cement is actually a polymer that polymerizes in situ generating heat.

Intracerebroventricular Injection of Tumor Necrosis Factor-αInduces Thermal Hyperalgesia in Rats

Neuroimmunomodulation, 1996
To investigate the role of tumor necrosis factor-α(TNF-α) in the brain in nociception, we injected recombinant human TNF-α(rhTNF-α; 1 pg–10 ng/rat) into the lateral cerebroventricle (LCV) in rats and observed the changes in paw withdrawal latency to radiant heat by using the plantar test for 90 min after injection. LCV injections of TNF-αat doses of 10

Laser Interstitial Thermal Therapy for Brain Metastases and Radiation Necrosis

2020
Laser interstitial thermal therapy (LITT) is a minimally invasive ablation technique that is emerging as a potential treatment for a wide array of surgical disorders. In the field of neurosurgery, applications range from refractory epilepsy to intracranial tumors not amenable to standard resection techniques.

Management of heat-induced bone necrosis following thermal removal of gutta-percha.

Quintessence international (Berlin, Germany : 1985), 2019
Many endodontically treated teeth require a post to improve the retention of the coronal restoration, which necessitates removal of the coronal part of the gutta-percha from the canal by thermal method, among other techniques. However, this technique carries the risk of heat conduction to the attachment unit of the periodontium and infliction of ...
