Abstract
The implant includes a stem terminating in a head. The stem is adapted to be inserted in the metacarpus of the thumb and the head to be disposed in a space obtained particularly by removing at least a portion of the trapezium. The surface of the head is constituted by a base connected to the stem and adapted to rest on the proximal end of the metacarpus, a distal surface portion opposite the base and serving as a contact surface with the bone located facing the proximal end of the metacarpus, and a connecting portion connecting the base and the distal surface portion of the head. The distal surface portion of the head is inclined relative to a longitudinal axis of the stem by a predetermined angle, such that, when the stem is mounted straight in the metacarpus, the distal surface portion of the head can be located in varus.
