An instrument assembly for an orthopedic procedure is disclosed. The instrument assembly can optionally include any one or combination of a reamer and a cut guide assembly. The cut guide assembly can be configured to couple to the reamer. The cut guide assembly can optionally include any one or combination of a clamp, a carriage and a cut block. The clamp can be selectively movable along a shaft of the reamer and lockable thereto. The first arm can project from the reamer. The carriage can be selectively moveable along a longitudinal length of the first arm. The cut block can be coupled to the carriage via one or more magnets.

Instruments and systems including a humeral cut guide assembly for an orthopedic shoulder replacement

A glenoid implant is provided and may include a body portion and a stem portion. The stem portion may extend from the body portion along a longitudinal axis. The body portion may include an articular side and a bone-engaging side opposite the articular side. At least a portion of the bone-engaging side may be disposed at a non-parallel angle relative to at least a peripheral edge of the articulation side.

Glenoid implant

Disclosed herein is an implant. The implant can include a body and a plurality of fixation members. The body can define an articular surface and a bone engaging surface opposite the articular surface. The bone engaging surface can define a groove that separates a first section of the bone engaging surface from a second section of the bone engaging surface. The plurality of fixation members can extend from the bone engaging surface.

Augmented glenoid with groove

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

A system for repairing a glenoid defect of a specific patient can include a patient-specific punch and a patient-specific shaping block. The patient-specific punch can form a patient-specific glenoid implant from a bone puck. The patient-specific shaping block can shape the patient-specific glenoid implant to match and fill a glenoid defect of a specific patient.

Patient specific reconstructive glenoid systems and methods

A bone reamer is provided and may include a shaft and a cutting element. The shaft may include a proximal end, a distal end, and a flexible portion. The flexible portion may be disposed between the proximal and distal ends. The cutting element may be carried by the shaft and may include a cutting surface facing the distal end of the shaft. The distal end of the shaft may be offset from the cutting surface.

Flexible bone reamer

An offset guide can include a body, an arcuate portion, a first fin, and a second fin. The body can have a first surface. The arcuate portion can extend from the body and have a second surface. The first surface and the second surface can define an opening. The first fin can extend from the first surface into the opening. The second fin can extend from the first surface into the opening. A portion of the first surface can be located between the first fin and the second fin and arranged at an angle relative to a longitudinal axis of the offset guide.

Offset guide

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.

Reamer and guide for glenoid augment preparation

Various joint replacements are disclosed herein, as are methods of use thereof. The joint replacements can have a flexible band or multiple flexible bands that can link together a first part of the joint replacement and a second part of the joint replacement. The flexible band or bands can be tensioned to establish proper tension in the patient's joint. In certain circumstances, the joint replacement can be a shoulder joint replacement.
