Vascularisation of the carpus, a systematic study.

The authors have injected the arteries and dissected 79 wrists. They propose a systematization of the vascular supply of the carpus, based on the major longitudinal and transverses axes; on the areas of arterial convergence and divergence, at the origin of 2 systems: the deep system (SAPRUC) is a vestige of the foetal morphology; it is periostal and sub-capsular. The superficial system (SASRUC) is predominant; it is constituted by the proximal and distal extracapsular pedicles.
