Abstract: A disposable brush head cartridge for a sonic or ultrasonic skin cleaning brush, specially adapted for use in surgical skin prep. The disposable brush head cartridge has a base configured to be removably attached to a sonic motor drive handle. The disposable brush head cartridge further comprises an upper bristle head sealed with respect to the base by a surrounding disposable cover spaced from the bristles. The cover defines a reservoir of pre-surgical skin cleaning fluid, in a first form soaking or pre-moistening the brush bristles until the cover is removed, and in a second form stored in a separate fluid-tight compartment in the cover and combined with the brush bristles after the cover is removed.

Abstract: Disclosed is a positioning instrument that includes: two branches equipped at the proximal end thereof with an opposite jaw between which the graft is positioned, the two branches moving closer to one another by a translation movement; and a drill bush including a first hole and a second hole, separated by a distance and sized for the passage and guidance of a bone drill bit. Also disclosed are an instrument kit as well as a method for attaching a graft.

Abstract: A humeral anchor for a shoulder prosthesis is disclosed. The humeral anchor includes a distal portion configured to be anchored in a proximal region of a humerus and a proximal portion, the proximal portion including a proximal face, where the proximal face includes an engagement feature configured to directly couple to a reverse shoulder insert having a concave proximal portion, and wherein the proximal face is further configured to directly couple with an anatomical shoulder insert having a convex proximal portion.

Abstract: A method for fixing a bone graft on a shoulder bone includes, before selection and use of a fixation device, a preoperative plan including collecting a preoperative imaging of a shoulder of a patient; virtually 3D modeling the shoulder; identifying at least one anatomical structure; and preoperative planning by one of sizing the graft, positioning the graft on the host bone, positioning the fixation device, and/or selecting the fixation device.

Abstract: Disclosed is a bone screw fixation device including two screws and only two. The bone screw includes: a first screw provided at its proximal end with a head for compressing the bone by an end-abutment; and a second screw provided at its distal end with a bone threading having a first helix pitch and at its proximal end with a bone threading having a helix with a pitch smaller than the first helix pitch.

Abstract: A modular shoulder prosthesis is provided. The modular prosthesis includes a stem, an anatomic insert, and a reverse insert. The stem is a unitary body that includes a distal shaft portion and a proximal portion. The proximal portion includes a stem face configured to directly couple to both the anatomic insert and reverse insert. The stem face includes a first engagement feature configured to couple directly to the reverse insert and a second engagement feature configured to couple directly to the anatomic insert. The stem can also include a metaphyseal portion between the shaft portion and proximal portion designed for use in humeral fracture repair procedures. The metaphyseal portion can include a medial arm and two lateral arms extending between the shaft portion and proximal portion, A window can be defined between the medial arm and the lateral arms, and a gap can be formed between the lateral arms.

Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.
