The synovial sheaths of the flexor digitorum of 70 pieces of fresh cadavers have been studied on the whole of their length as far as the basis of the fingers: 20 have been injected with a latex or a physiologic solution, after the ablation of the palmar aponeurosis and of the superficial palmar arch. The arteries of the 50 other pieces have been injected with coloured latex solution from humeral artery. The proximal limit of the superficial sheaths is located 5 centimetres above the radiocarpal articular line and this of the deep sheaths 7 centimetres. In the metacarpal area, the superficialis central sheath presents peritendinous expansions, which realise an uninterrupted connection with each digital sheath. It is the aponeurotic and vascular extrinsic compressions, which simulate the interruption of these expansions. The proximal synovial arteries have a muscular origin. The antibrachial collateral arteries, 3 pairs in number, arise from the radial and the ulnar arteries. The distal synovial arteries come from the palmar arches and from their branches: superficial branches for the superficial sheaths and deep branches for the deep sheaths. There is many anastomoses between the different synovial arteries. Two are particularly developed and connect the proximal arteries to the palmar arches: the superficial longitudinal anastomotic artery; which runs close along the medial edge of the median nerve; the deep longitudinal anastomotic artery, which gives the nutritious branches for the tendons of the flexor digitorum. This disposition allows to create two synovial flaps of gliding and vascular help, centred on the anastomotic longitudinal arteries, pediculated on the volar archs and distal-ward rotated.(ABSTRACT TRUNCATED AT 250 WORDS)
