Anatomic osteochondral glenoid reconstruction for recurrent glenohumeral instability with glenoid deficiency using a distal tibia allograft.

Glenoid Reconstruction With Distal Tibia Allograft for Recurrent Anterior Shoulder Instability.

Anterior glenoid bone loss is present in nearly all cases of recurrent anterior glenohumeral instability. Treating glenoid bone loss in the setting of recurrent instability is challenging, and often, soft tissue stabilization procedures in isolation are inadequate. The nonanatomic, incongruous joint resulting from most bony augmentation procedures has motivated investigators to find an alternat...

Comparison of glenohumeral contact pressures and contact areas after glenoid reconstruction with latarjet or distal tibial osteochondral allografts.

BACKGROUND Glenoid reconstruction with distal tibial allografts offers the theoretical advantage over Latarjet reconstruction of improved joint congruity and a cartilaginous articulation for the humeral head. Hypothesis/ PURPOSE To investigate changes in the magnitude and location of glenohumeral contact areas, contact pressures, and peak forces after (1) the creation of a 30% anterior glenoi...

Comparison of Glenohumeral Contact Pressures and Contact Area after Glenoid Reconstruction with Latarjet or Distal Tibial Osteochondral Allograft

Allograft reconstruction for glenoid bone loss in glenohumeral instability: a systematic review.

PURPOSE The aim of this study was to assess clinical outcomes and radiological outcomes after osteochondral allograft reconstruction for glenoid bone loss. METHODS Glenoid bone loss can occur in the setting of recurrent glenohumeral instability and poses a challenge for surgeons. Reconstruction of these defects with allografts has been proposed as an alternative to both arthroscopic stabiliza...

Comparison of glenohumeral contact pressures and contact areas after posterior glenoid reconstruction with an iliac crest bone graft or distal tibial osteochondral allograft.

BACKGROUND Posterior glenoid bone deficiency in the setting of posterior glenohumeral instability is typically addressed with bone block augmentation with iliac crest bone grafts (ICBGs). Reconstruction with fresh distal tibial allograft (DTA) is an alternative option, with the theoretical advantages of restoring the glenoid articular surface, improving joint congruity, and providing the biolog...
