The present invention provides a new and improved orthosis for use in effecting relative movement between bones in an arm of a patient. The apparatus includes a lower cuff gripping distal bone, such as a wrist, and an upper cuff gripping a proximal bone, such as an upper arm. The lower cuff is secured in a rotatable drive assembly substantially coincident to a longitudinal axis of a medial bone, such as the forearm, during rotational distal adjustment. The angle between the forearm and the upper arm is adjustable and can be securely fixed at a desired angle. The rotation of the rotatable drive assembly effectuates the pronation and supination of the hand and wrist relative to the patient's forearm. The orthosis of the present invention can be disassembled with interchanging parts substituted depending on the patient's needs.

La présente invention propose une nouvelle orthèse améliorée à utiliser dans l'exécution d'un déplacement relatif entre les os du bras d'un patient. L'appareil comprend une embrasse inférieure qui serre un os distal, tel qu'un poignet, et une embrasse supérieure qui serre un os proximal, tel qu'un bras. L'embrasse inférieure est fixée dans un ensemble d'entraînement rotatif de manière sensiblement coïncidente avec un axe longitudinal d'un os médian, tel que l'avant-bras, pendant un ajustement distal de rotation. L'angle entre l'avant-bras et le bras est ajustable et peut être solidement attaché à l'angle voulu. La rotation de l'ensemble d'entraînement rotatif effectue la pronation et la supination de la main et du poignet par rapport à l'avant-bras du patient. L'orthèse de la présente invention peut être désassemblée avec des parties interchangeables remplacées en fonction des besoins du patient.
