Dorsal forearm plate having a three-dimensional concave shape adapted to the shape of the dorsal forearm such that the dorsal forearm may rest on the forearm plate, the dorsal forearm plate has an essentially rectangular extension having opposing long sides and opposing short sides and has a substantially rigid unitary body adapted to underlie the posterior of the patients hand, wrist and forearm, the plate is provided with two attachment bands, a distal and a proximal attachment band, adapted to attach the plate at the dorsal forearm of a patient. The shape of the side of the plate adapted to face the forearm during use, is adapted to the anatomy of the forearm in that it comprises two elongated depressions running in the longitudinal direction of the plate such that, during use of the plate, the ulnar bone and radius bone of the patient rest in the respective depression and that an elongated ridge, formed between the depressions, is adapted to extend into the softer tissue between the bones in order to orient and stabilize the forearm when attached to the plate. The invention also relates to a radial artery compression system comprising a dorsal forearm plate and a compression unit.Linvention concerne une plaque davant-bras dorsal ayant une forme tridimensionnelle concave, adaptée à la forme de lavant-bras dorsal, de telle sorte que lavant-bras dorsal puisse reposer sur la plaque davant-bras, la plaque davant-bras dorsal ayant une extension essentiellement rectangulaire qui possède de grands côtés opposés et de petits côtés opposés, ainsi quun corps unitaire sensiblement rigide, adapté pour soutenir la partie postérieure de la main, du poignet et de lavant-bras du patient, la plaque étant munie de deux bandes de fixation, une bande dattache distale et une bande dattache proximale, conçues pour fixer la plaque à lavant-bras dorsal dun patient. La forme du côté de la plaque conçue pour faire face à lavant-bras pendant lutilisation est adaptée à lanatomie de lavant-b
