Posterior Arthroscopic Anatomic Glenoid Reconstruction
Bibliographic record
Abstract
Posterior bone loss following posterior instability of the shoulder can lead to poor patient outcomes and increased likelihood of subsequent dislocations. Unlike in cases of anterior instability, the critical amount of bone loss that warrants surgical intervention in posterior instability has not been established. Posterior instability and bone loss are commonly seen in traumatic settings where cumulative dislocations occur. Similar to surgical treatment of anterior instability, both arthroscopic and open procedures have been used, with the former gaining momentum as the preferred method. To address resultant bone loss, surgeons can use a variety of grafting techniques and sources for augmentation of the posterior glenoid deficit. Here we describe an adaptation of the arthroscopic anatomic glenoid reconstruction for posterior instability with bone loss using a distal tibia allograft. This arthroscopic technique allows for excellent surgical visualization, graft delivery, and anatomic reconstruction of the articular surface of the glenoid.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
