Shoulder / Glenoid Reconstruction
Shoulder / Glenoid Reconstruction
In shoulder or glenoid reconstruction procedures, allograft wedges can be used to restore the anatomy and function of a glenoid that has been deformed due to degenerative disease, traumatic injury, or previous surgery. Specifically, they can be used in procedures such as glenoid bone grafting, often performed as part of a shoulder arthroplasty or in the repair of a large Hill-Sachs lesion in the context of shoulder instability. Allograft bone wedges play a key role by providing a structural support that facilitates the restoration of normal shoulder biomechanics.
- This study presents a technique using iliac crest allograft to repair large glenoid defects in patients with recurrent anterior shoulder instability, yielding significant improvements in shoulder strength and patient self-reported outcomes over a four-year period. The method, offering a safe and clinically effective alternative to previously described procedures, exhibited an 80% osseous union rate at 6 months.
- This study presents a "hybrid" surgical technique for treating large Hill-Sachs lesions, which are humeral head fractures that can contribute to recurrent shoulder instability. The technique involves an arthroscopic capsulolabral repair, a minimally invasive procedure to restore the stability of the shoulder joint, combined with an open posterior approach to the humeral head for bone grafting. In this technique, an allograft is prepared and inserted into the reshaped defect, and secured with screws, which helps in restoring functional shoulder stability.
- This study compared the outcomes of arthroscopic tricortical iliac crest autograft and allograft bone blocks for recurrent traumatic anterior shoulder instability. Through analysis of 22 patients' data, the research found that both autograft and allograft can alleviate shoulder instability symptoms, however, autograft yielded improved Oxford Shoulder Instability Score, higher union rate, and less bone resorption.
