Pearls and Pitfalls of the Described Glenohumeral Resurfacing Technique

Pearls	Pitfalls
In cases for revision Trillat, the coracohumeral distance will be significantly decreased due to the previous lateralizing coracoid osteotomy. We recommend coracoid osteotomy at its base to allow adequate access to the glenohumeral joint.	Given the revision nature of this procedure, be mindful of excessive scarring and altered anatomy. Without special care, injury may occur to the axillary nerve at the inferior aspect of the subscapularis tenotomy or during glenoid preparation.
Once the coracoid osteotomy is performed, the osteotomized bone is removed and the conjoint tendon whipstitched for later repair to the coracoid base with a suture anchor.	If the glenoid depth is not confirmed with the glenoid trial, the implant with underlying cerement may sit proud in the glenoid inlay recess.
The inlay glenoid implant should sit flush with the native glenoid or slightly recessed. This should be visualized carefully during trialing. Further, a “snowman” type implant can be used for larger glenoid lesions.
If the humeral head is flattened, the centering shaft should not be advanced the full depth, stopping 2-3 mm before the lip reaching the articular surface. This allows the centering shaft to be placed slightly proud to the surface to allow appropriate humeral implant positioning.
