A glenoid implant comprises a body comprising: an articular surface and a scapula-engaging surface, the scapula-engaging surface including first and second portions angled relative to each other; and a fixation feature extending from the scapula-engaging surface. A method comprises: forming a planar bone surface at a glenoid using a guide pin; forming a first bore into the glenoid located near the guide pin; forming a second bore into the glenoid offset from the first bore; inserting an augment ream guide into the first and second bores; and forming an angled bone surface at the glenoid relative to the planar bone surface using the augment ream guide. A ream guide comprises: a base having first and second surfaces; a bone peg extending from the first surface; an alignment peg spaced from the bone peg; and a guide peg extending from the second surface at an oblique angle to the bone peg.

Patient-specific augmented glenoid systems and methods

Methods, systems and devices for pre-operatively planned total or partial joint surgery including, for example, anatomic and reverse shoulder surgery guides and implants. There are also methods for pre-operative planning methods for designing glenoid implants and prostheses, particularly with patient-specific augmentation, based on considerations of multiple factors affecting the outcome of a selected reverse or anatomic shoulder surgery. There are also described methods of performing total or partial joint surgery, including anatomic or reverse shoulder surgery, using surgery guides and implants in patients undergoing joint surgery.

The present disclosure provides reaming apparatuses. The reaming apparatuses can comprise a base guide, a reamer, and a reamer driver. The base guide can define a base guide through bore and a base guide articulating surface. The base guide articulating surface can be oriented at an angle relative to the base guide through bore. The reamer can define a reamer articulating surface operable to allow rotation of the reamer on the base guide articulating surface. The reamer driver can operate with the reamer to cause rotation of the reamer when the reamer driver rotates.
