Extensor Quadriga: Pathomechanics and Treatment
Bibliographic record
Abstract
The extensor tendons to the index, long, ring and small fingers are motored by the common extensor digitorum communis muscle body. Effective function of this muscle can only occur if the gliding amplitude of each of its four extensor tendons is normal. As a corollary, limitation of the excursion of any of the individual tendons by adhesions at a fracture or tendon repair site, a fixed flexion contracture at the metacarpophalangeal joint, or by rupture, attenuation or laceration of a saggital band or juncturae tendinum, will result in reduction of the excursion of the adjacent extensor tendons. This pathological state has been termed the extensor quadriga because of its similarities to the analogous pathology affecting the flexor digitorum profundus system. Improper management of this clinical entity may lead to an abnormal pathomechanical kinematic chain imbalance. Early identification and treatment is critical to address this entity appropriately.

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.
