Abstract: Techniques are described for determining a pre-morbid shape of an anatomical object. Processing circuitry may determine an aligned shape based on image data with under- or over-segmentation. The processing circuitry may utilize the aligned shape and a shape model such as a mean shape model of the anatomical object to register the aligned shape to the shape model and generate information indicative of the pre-morbid shape of the anatomical object.

Abstract: A bioactive filamentary structure includes a sheath coated with a mixture of synthetic bone graft particles and a polymer solution forming a scaffold structure. In forming such a structure, synthetic bone graft particles and a polymer solution are applied around a filamentary structure. A polymer is precipitated from the polymer solution such that the synthetic bone graft particles and the polymer coat the filamentary structure and the polymer is adhered to the synthetic bone graft particles to retain the graft particles.

Abstract: A radial head assembly is provided that includes a stem, a collar, a locking ring, and an articular member. The stem has a convex articular head on one end thereof. The locking ring has a ring wall, which has a ring opening. The ring wall has an angular outer surface and a slot configured to permit the ring wall to radially expand. The angular outer surface engages an angular portion of an interior surface of the collar. The articular member and the locking ring define an articular space within the collar. The articular space is configured to receive the convex articular head.

Abstract: A glenoid prosthesis includes a head portion and an anchor. The head portion includes a first surface adapted to contact a glenoid and an opposed second surface that is at least partially concave. The anchor extends from the first surface of the head portion and terminates at a distal end. At least one first circular member is disposed between the head portion and the distal end of the anchor and encircle the anchor. At least one second circular member is disposed between the head portion and the distal end of the anchor and encircles the anchor. The at least one first circular member is adapted to engage cortical bone of a glenoid and the at least one second circular member is adapted to engage cancellous bone of a glenoid when the glenoid prosthesis is implanted.

Abstract: Provided is a method of manufacturing a prosthesis for a fractured long bone of a patient, the method including the steps of: A) providing data representative of the fractured long bone in a patient; B) based on said data, designing the prosthesis specifically to the patient, the prosthesis including a stem part that is configured to secure fragment(s) of the fractured long bone at chosen securing position(s) that will apply chosen mechanical stress onto the bone fragments and reduce the risk of osteonecrosis of the bone fragments.
