A study of clinical anatomy of the safe zone for the volar approach for wrist arthroscopy.

Objective: The current study was to perform an anatomical observation of the volar approach for wrist arthroscopy and to establish the safe zone for this approach.

Methods: Eight preserved specimens and 2 fresh specimens were used to simulate the medial-to-lateral operation and to mark the volar approach. Based on anatomical measurements of the volar approach, the closest distances from the 1/2, 6R, 6U, VR, VR' and VU approaches to the adjacent important structures were established.
