Thermological Study of Drilling Bone Tissue with a High-speed Drill

Neurosurgery, 2000
To perform a detailed quantitative analysis of the effect of intermittent drilling and irrigation to lower the temperature during high-speed drilling.We examined the thermal changes for 15 bone flaps while drilling a 7- x 7-mm area for 18 seconds and a specific point for 9 seconds, under the following conditions: continuous or intermittent drilling ...

HIGH - SPEED BONE DRILLING

2005
In the case of fracture or crack of human bones, a surgery method gives the best healing results because a traumatologist drills the bone, sets the immobilization screws and plates and with that procedure achieves an optimal immobilisation. A problem occurs if during the bone drilling, the maximal temperature of the bone tissue around the hole ...

Bone Drilling Medical Training System

2008
This chapter describes a bone drilling medical training system and the methodologies for force skill training in virtual environments (VEs). The training system aims at teaching to apply force in a certain range, thus keeping the drilling thrust velocity constant for given time. First, the issues to create the VE, such as collision detection and haptic

Fracture of a Bone Drill

2019
Abstract A stainless tool steel bone drill broke during an operation on a patient and was examined. It showed two fatigue fractures, one of which had started from a sharp-edged, coarsely milled slot (fracture A1), and the other from a point on the outer sheath surface which was not subjected to particularly high stresses (fracture A2 ...

Hollow Bone Jade Drilling Experiments

2020
The application of jade as a material for the manufacturing of various products began in the Paleolithic. When processing jade, the ancient population of Eurasia used the technique of grinding, polishing, sawing, cutting, and drilling. This work is devoted to the study of the technology of drilling jade using hollow bones.

ASEPTIC NECROSIS AND BONE DRILLING

Archives of Surgery, 1942
Bone drilling as a therapeutic procedure is not altogether modern. About a hundred years ago Daniel Brainard, 1 a professor of surgery in Chicago, experimented successfully with subcutaneous bone drilling in animals. This led him to employ it in treating pseudarthrosis in human beings. Brainard recorded his investigations in an elaborate study which he

Bone canal drilling in chondropathy

1986
The first bone canal drilling was performed in 1845 by Dieffenbach in Berlin and the next in 1929 by Beck in the United States. Both authors carried it out to treat pseudarthrosis. The first instance of bone drilling in chondropathy (osteochondrosis dissecans) was published - as far as we know - in Bone and Joint Surgery and referred to a report of ...

INFLUENCING PARAMETERS IN BONE DRILLING

2003
Since fracture or crack of human bones means disturbance of the bones integrity, it is necessary to return the bone as precisely as possible into its previous position and to immobilise it to insure maximum avoidance of motion at the fracture site. In order to achieve optimal immobilisation, i.e.
