Abstract: A jig for resurfacing the head of a femur comprises a centering guide defining a centering axis. It further comprises: a support suitable for fitting on a head of the femur and defining an envelope surface forming a portion of a sphere, the centering guide being fastened to the support with the centering axis aligned on a diameter of the sphere; and at least one abutment arm for coming into abutment against a predefined portion of a neck of the femur, the abutment arm being connected to the support and having a distal end that bears against the corresponding predefined portion when the support is fitted on the head of the femur with the centering axis aligned on the central axis of the neck of the femur or with a small amount of valgus.

Abstract: An instrument including a distal receiver portion for receiving a compression staple that includes two branches interconnected by a transverse bridge. The instrument further including a holder suitable for holding a first zone of the bridge of a staple stationary relative to the receiver portion, the first zone being either the two end portions of the bridge that are connected to the branches or the central portion of the bridge. The instrument further including a deformation tool for deforming a staple from an initial configuration for implanting in a bone towards a compression-applying configuration, said deformation tool adapted to apply forces to the second zone of the bridge of the staple producing a resultant that opposes the forces applied to the first zone by the holder.

Abstract: A compression staple according to an embodiment of the present invention includes two arms connected by a transverse bridge. Each arm includes an anchor portion and a manipulation portion arranged so as to extend from one another and connected by a separation mechanism or breakaway feature. The anchor portion is used to anchor the arm in a bone while the manipulation portion is used to guide the arm in displacement relative to the bridge.
