An active compression orthopedic screw (100, 100', 800) includes a first shaft member (160) positioned at a distal end (104) of the screw (100, 100', 800), a second shaft member (140) positioned at a proximal end (102) of the screw (100, 100', 800), and an elastic member (200) having a first (220) and a second (210) end. According to one exemplary embodiment, the first end (220) of the elastic member (200) is coupled to the first shaft member (160) and said second end (210) of the elastic member (200) is coupled to the second shaft member (140), the elastic member (200) being configured to exert a force drawing the first (160) and second (140) shaft members together.

Une vis orthopédique de compression active (100, 100', 800) comprend un premier élément de tige (160) positionné à une extrémité distale (104) de la vis (100, 100', 800), un second élément de tige (140) positionné à une extrémité proximale (102) de la vis (100, 100', 800) et un élément élastique (200) possédant une première (220) et une seconde (210) extrémité (210). Selon un mode de réalisation cité à titre d'exemple, la première extrémité (220) de l'élément élastique (200) est accouplé à au premier élément de tige (160) et à ladite seconde extrémité (210) de l'élément élastique (200) est accouplé au second élément de tige (140), l'élément élastique (200) étant configuré pour exercer une force tirant ensemble les premier (160) et second (140) éléments de tige.
