La vascularisation de la gaine synoviale commune et des tendons des muscles fléchisseurs dans le canal carpien

Abstract

The detailed anatomy of the tendon apparatus, the blood supply of the superficial (FDS) and profundus (FDP) flexor muscles and the blood supply of the common synovial sheath in the carpal tunnel were studied on 200 hundred upper extremities from fresh human cadavers. The injection of coloured latex or the aqueous solution of India ink and gelatin revealed a complex arterial network. Dissection of the carpal tunnel revealed the existence of different sources of the blood supply of the tendons of the flexor muscles and carpal sheath. The different sources and zones of vascularization are described. This study concerns the synovial and tendinous apparatus of the flexor muscles as well as their blood supply in the carpal tunnel. These data may be of interest hand surgeons.
