Oscillating cast saw
A non-surgical motorized saw with a small-toothed blade that oscillates (vibrates) back and forth over a minimal arc rather than spinning continuously; this motion breaks down rigid materials such as plaster or fiberglass but does not cut skin, which moves with the blade instead of resisting it.
How it is used
Removing casts and rigid bandages in trauma clinics, emergency departments and rehabilitation settings; the cast is cut along a line and then opened with a cast spreader, without cutting the patient's limb.
Clinical tip
Although generally safe for skin, it can cause friction burns or small lacerations over bony prominences (elbow, wrist, malleolus); advance without pressing down and let the blade cool during long casts.
