Abstract: An osteotome having a shaft assembly that includes a guide extending in a longitudinal direction of the shaft assembly, and a blade adjacent the guide and extending in the longitudinal direction of the shaft assembly.

Abstract: A surgical instrumentation system for a shoulder arthroplasty that includes a retractor that includes a curved section structured to wrap around and substantially engage a posterior portion of a humeral head, an alignment guide extending from the retractor. The alignment guide includes a primary alignment shaft and a resection guide attachable to the retractor, the resection guide including a guide surface for guiding a cutting tool.

Abstract: A surgical instrument system for positioning a guide pin about a glenoid cavity that includes an anterior retractor. The anterior retractor includes a tip structured to engage a scapula, a lateral retractor shaft extending from the tip, and a medial retractor shaft extending substantially transverse from the lateral retractor shaft. The system further includes an alignment guide attachable to the anterior retractor, the alignment guide including an alignment guide shaft, a guide about a distal end of the alignment guide shaft, and a fastener for connecting the alignment guide shaft to the anterior retractor such that a longitudinal axis of the alignment guide shaft is aligned with a longitudinal axis of the medial retractor shaft when fastened thereto.

Abstract: A tendon anchoring assembly that includes an anchor and a washer. The anchor includes an elongated body and a substantially circular head and the washer includes an inferior face having gripping protrusions, and a through hole sized to receive a portion of the substantially circular head. A shoulder implant assembly that can be used in conjunction with the tendon anchoring assembly is also disclosed.

Abstract: An orthopedic medical device assembly that includes a first bearing for attachment to an implant and a second bearing for attachment to an implant, such as a glenosphere.
