| dc.description | Surgical procedures such as osteotomy and hip replacement involve the cutting of
bone with the aid of various manual and powered cutting instruments including
manual and powered bone saws. The basic mechanics of bone sawing processes are
consistent with most other material sawing processes such as for wood or metal.
Frictional rubbing between the blade of the saw and the bone results in the generation
of localised heating of the cut bone. Research studies have been carried out which
consider the design of the bone saw which deals with specifics of the saw teeth
geometry and research which examines the effect of drilling operations on heating of
the bone has shown that elevated temperatures will occur from frictional overheating.
This overheating in localised areas is known to have an impact on the rate of healing
of the bone post operation and the sharpness life of the blade.
The purpose of this study was to measure the temperature at three zones at fixed
intervals of 3mm, 6mm, and 9mm away from the cutting zone. It should be noted that
it was the first time that this measurement technique was used to measure the
temperature gradient through the bone specimen thereby establishing the extent to
which clinicians are experiencing thermal injury during sawing of bone while using a
reciprocating saw. The effect of various cutting feed rate on temperature elevation
was also investigated in this research.
The results showed that there will be a region of bone at least 9mm either side of the
cutting blade experiencing thermal injury as temperatures in this region exceeded the
threshold temperature of 44°C for necrosis (cell death). | en |
