Influence of irrigation solutions on oscillating bone saw blade performance

Abstract

The influence of irrigation on bone cutting was determined by measuring the biomechanical performance of a bone cutting saw during irrigation with various solutions. Solutions of 0.9% saline and 10, 20, and 30% poloxamer-188 were used as the irrigant. A 10% solution of poloxamer-188 was judged to be the superior irrigant because it successfully maintained bone temperature at a controlled level without interfering with the rate of bone removal.

Intraosseous heat generation during sonic, ultrasonic and conventional osteotomy

“…oscillating saw osteotomy could potentially jeopardize the biological potency of the bone. Therefore, both bur and oscillating saws are usually cooled during the cutting process (Ark et al, 1998).…”

In Vitro Performance Testing of Two Arcuate Oscillating Saw Blades Designed for Use During Tibial Plateau Leveling Osteotomy

“…Previous studies measured temperature change during drilling tests using cadaveric samples of bovine mandible, and recorded reliable temperature curves when the thermocouples were positioned within 2 mm of the prospective position of the drill hole 21 . Other studies used thermocouples embedded in the cutting tools to measure the temperature at the tool‐sample interface 8–10,12,14,17,18 . While this testing method is technically less demanding, it has several disadvantages compared with our methods.…”

“…The most appropriate orthogonal cutting model allows testing of saw blade performance with a constant, measured load applied to the blade 8–11,14 . Previous studies have demonstrated an inverse relationship between applied load and temperature elevation within the test specimen 11,12,15 .…”

“…In studies that have addressed this subject, the outcome measures recorded most frequently were rate of bone removal and maximum temperature produced by the saw blade 8–13 . The latter is considered an important outcome measure because of the potential for thermal necrosis as a result of the high‐speed cutting action of the oscillating saw blade 14 . When generated heat surpasses the threshold temperature of bone tissue, the organic matrix is irreversibly damaged and necrosis of the bony ends may occur 10 .…”

“…Factors reported to influence the performance of oscillating saws during bone cutting experiments include saw blade design, 10–13 durability of the blade, 9,11 application of irrigation fluid, 12–14,17 and feed rate or force applied to the saw 8–14 . We are unaware of any previous studies which have assessed the influence of the above factors on the cutting performance of TPLO oscillating saws.…”
