This surgical instrumentation assembly is for positioning a shoulder prosthesis, the shoulder prosthesis comprising a patient-specific shoulder implant adapted to fit onto a glenoid cavity of the scapula of a patient. The assembly comprises a patient-specific impacting device having an underside surface congruent with the glenoid cavity of the scapula of the patient, said underside surface being provided with protrusions adapted to perforate the cortical bone of the scapula upon impact of the impacting device against the scapula by a one-sided translation movement.

Disclosed are prosthesis systems and methods that provide ways by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.

A system for sizing the resected surface to provide metaphyseal referencing and to properly guide a tool into a central portion of the canal in the diaphysis. The system can include a sizing feature to approximate the size of the metaphysis. The system can also include a base configured to contact the metaphysis and a guide feature configured to guide a tool along a central portion of the canal in the diaphysis.

Various apparatus and methods for implanting glenoid prostheses are disclosed. In various embodiments, a method for performing shoulder surgery can include guiding a guide pin into the glenoid surface along a reaming axis. A partial reaming guide can be placed in contact with the glenoid surface over the guide pin. A reamer can be guided over the guide pin to ream the glenoid surface. The reamer can be further advanced over the guide pin until the reamer contacts the partial reaming guide, whereby such contact limits reaming to only a portion of the glenoid surface.

Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.

A humeral implant system, for example, includes an implant and a cutting guide system. The implant is a spherical wedge having an elongated curved upper surface having a first edge and a spaced apart second edge, a first surface having a curved upper edge joined to the first edge of the elongated curved upper surface, and a second surface having a curved upper edge joined to the second edge of the elongated curved upper surface. A lower edge of the first surface is joined to a lower edge of the second surface. The first surface and the second surface are disposed at an angle. The cutting system has a body having a first guide and a second guide for resecting a cutout in a humeral head, in which the cutout has a first surface and a second surface corresponding to the first surface and the second surface of the implant.

A glenoid implant system, for example, includes a glenoid implant and a glenoid cutting guide. The glenoid implant includes a body having a concave surface with a first curved edge portion and a second curved edge portion, and an attachment surface having a concave edge portion joined to the second curved edge portion of the concave surface. The concave surface and the attachment surface are disposed at an angle. The glenoid cutting guide includes a body having a convex surface engageable with a surface of a glenoid cavity and a cutting guide surface for resecting a cutout in a glenoid cavity, the cutout having a curved edge portion corresponding to the second curved edge portion of the glenoid implant.

This disclosure relates to surgical devices and methods for repairing bone defects. The defect indicators disclosed herein may be utilized to indicate a precise location of the defect associated with an articular surface of a joint.

Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed. Some of the methods include inserting a guide pin into the glenoid of the patient, advancing a reciprocating surgical rasp over the guide pin, reciprocating the surgical rasp so as to abrade bone tissue to form a cavity shaped to receive the glenoid component, and implanting the glenoid component in the cavity.

A humeral head implant system includes a head component including a first articulating surface, a second bottom surface extending from the first spherical articulating surface, a first cavity extending a first distance into the head component from the second bottom surface, and a second cavity extending into the head component along a cavity axis. The head component defines a head axis extending through a center of the first articulating surface parallel to the cavity axis. A base component defines a slot extending from a first width to a second width. An insert component includes an insert body, a first engagement feature, and a slot engagement feature. The first engagement feature is received in the second cavity along the cavity axis. The insert body has an insert thickness less than the first distance, and the slot engagement feature slides into the slot in a direction transverse to the cavity axis.
