Microtomy
Manual rotary microtome use in histology
laboratories requires performing many repetitive functions. In
the
course of one day, a laboratory technologist may use between 40 and 50
cassettes or blocks a day, hence turning the microtome wheel for at
least a 1000 time. This is not only repetitive work, but turning
microtome's wheel also requires force or forceful exertion. Other
repetitive microtome-related functions such as replacement of specimens
and use of trimming wheel increase the probability of acquiring MSD.

Associated Risk Factors:
Preventive
Measures:
- Place microtome on appropriate workbench
(appropriate
height). Take into consideration the way work will be performed
(standing or sitting).
- If sitting is required, make sure the workbench
allows enough clearance for leg and thighs.
- Use only adjustable chair or stool with
built-in foot and arm rest.
- Make sure sharp edges are not an issue.
- Protect wrists and forearms from contact
pressure. Pad sharp edges.
- Use less force when turning handwheel.
- Take frequent small breaks from microtome work
every 20 minute.
- If economically feasible, replace manual rotary
microtome with an automatic one.
