Embodiment Construction

[0042] As noted above, the present application relates to improved devices, systems and methods for performing open Latarjet-type surgery, eg, to correct glenoid bone loss. In an exemplary embodiment of a Latarjet-type surgery, the coracoid may be secured to the glenoid, typically by screws. In particular, the surgeon may drill two or more holes into each of the coracoid and glenoid, and align the coracoid and glenoid holes. Subsequently, screws may be positioned within the bone holes for fixation. Notably, in such procedures, the likelihood of successful bony fusion may depend on the orientation and alignment of the coracoid and glenoid holes used to position the coracoid graft surface on the glenoid graft surface. For example, misalignment of the coracoid and glenoid foramina may result in poor contact between the glenoid and coracoid graft surfaces or insufficient contact pressure at the graft interface, reducing the likelihood of successful bony fusion. Accordingly, impr...

Abstract

Embodiments of the present disclosure relate to instruments that facilitate coracoid-glenoid fixation in a Latarjet procedure. For example, a single instrument, a coracoid resection tool, can be provided / utilized to prepare the coracoid bone graft for size, planarity and drilling. A glenoid drill guide may also be provided / utilized that uses a sized offset to place the coracoid graft flush with the glenoid. Further embodiments of the present disclosure relate to corresponding methods employing the apparatus. For example, the surgeon may use the coracoid resection tool as a guide to plan the inferior coracoid surface that will be the surface of the coracoid graft. The coracoid resection tool also guides the placement of coracoid holes along the length of the coracoid and orients the holes approximately perpendicular to the planed coracoid graft surface. For example, the proximal coracoid hole may be positioned toward the proximal (ie, cut end) of the resected coracoid process, while the distal coracoid hole may be positioned toward the distal (ie, tip) end of the resected coracoid process.

Description

[0001] Cross References to Related Applications [0002] This application is related to, and claims priority from, U.S. Provisional Application Serial No. 62 / 131,099, filed March 10, 2015, and also titled "OPEN LATARJET FOR CORRECTION OF ANTERIOR-INFERIOR GLENOID BONE LOSS," which is contained in This is incorporated herein in its entirety. technical field [0003] The present application relates to surgical systems and methods, and more particularly, to improved devices, systems and methods for performing open Latarjet-type surgical procedures, eg, to correct glenoid bone loss. The Latarjet procedure generally may involve the removal and transfer of a segment of the coracoid process and its attached muscles to the anterior portion of the glenoid in order to prevent further dislocation of the shoulder joint. In particular, the diverted segment of the coracoid process advantageously acts as a bone block that physically prevents the shoulder from pinching out of the socket. In...
