[Office workplace at a computer monitor from an occupational-orthopedic view].

Typical back problems as well as complaints in the shoulder-arm-hand system are increasing as the volume of sedentary office work at the computer screen rises. Various legal rules precisely define preventive measures. However, basic orthopedic-biomechanical principles are not being taken into consideration. Orthopedists as well as occupational physicians are equally challenged to enforce those legal guidelines by beginning to raise awareness of the principles and thus contributing towards improvement of working conditions.
