Degenerative disease of the distal interphalangeal joint and sesamoid bone in calves: 9 cases (1995–2004)
Bibliographic record
Abstract
OBJECTIVE: To evaluate the clinical signs, diagnosis, treatment, and outcome associated with distal interphalangeal joint (DIJ) degenerative disease in calves. DESIGN: Retrospective case series. ANIMALS: 9 calves with degenerative disease of the DIJ. PROCEDURES: Medical records of calves with lameness for which the cause had been localized to the distal aspect of a limb but without evidence of trauma or sepsis were included. Signalment and results of physical, lameness, radiographic, and postmortem examinations were recorded. Outcomes of medical and surgical treatments were evaluated. RESULTS: All 9 calves had forelimb lameness (4 bilaterally). The medial digit was affected in 12 limbs and the lateral digit was affected in 9 limbs. Radiographic examination revealed bridging osteoproliferation along the abaxial and palmar aspects of affected DIJs (18/21), subchondral cyst-like lucencies (19/21), and sclerosis (16/21). The DIJ was resected in 3 calves (7 joints), resulting in resolution of lameness within 3 months. Medical management was attempted in 4 calves (6 joints), and 2 calves (6 joints) did not receive treatment; 5 calves had a normal stance within 5 months. Results of postmortem computed tomographic and histologic examination were in accordance with degenerative joint disease processes. CONCLUSIONS AND CLINICAL RELEVANCE: Degenerative disease of the DIJ should be considered in calves with insidious, progressive forelimb lameness. Although the etiology of this process remains undetermined, results of radiographic, computed tomographic, and histologic examinations suggested an underlying developmental anomaly, such as osteochondrosis. Surgical treatment appeared promising on the basis of postoperative resolution of lameness in all surgically treated calves.

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.
