[Current observations on the morphology and biomechanics of the human flexor tendon sheath].

Authors give a short description, based on own experimental work and literary data, of the tendon sheat biomechanics of the long fingers. The importance of the integrity of the tendon sheat--subcutis--skin unit is presented. Starting from this, a new possibility of exposing the flexor tendons, a laterobasal exposure is shown. The experimental character of their work is stressed, it is however underlined that clinical importance is attached to their aspect.
