Unilateral Repair of an Avulsion Fracture of the Caudal Cruciate Ligament Origin Combined with a Ruptured Cranial Cruciate Ligament in a Dog
Bibliographic record
Abstract
Abstract Caudal cruciate ligament (CaCL) femoral avulsion fractures are rarely documented, and a true incidence is unclear. A literature search revealed very few cases of a CaCL avulsion fracture or rupture combined with a cranial cruciate ligament (CrCL) rupture. Only a single case report described surgical treatment of this combination by fragment removal and stifle stabilization with an extracapsular suture. A 1-year-old female spayed Labrador Retriever presented with a hindlimb lameness. Examination revealed cranial drawer of the stifle, consistent with CrCL rupture. Stifle effusion, as well as a bone opacity seen in the trochlear groove, was evident on radiographs. At surgery, arthrotomy revealed a torn CrCL as well as an avulsion fracture of the CaCL origin from the medial femoral condyle. The avulsion fracture was reduced, and three 0.035-inch Kirschner's wires (K-wires) were placed in a divergent fashion through the fragment into the medial femoral condyle. A tibial plateau leveling osteotomy (TPLO) was then performed. Six-week recheck radiographs showed good healing of the TPLO as well as the repaired avulsion fracture, despite breakage of one of the K-wires. The dog was mildly lame at the 6-week follow-up and subsequently improved to clinically normal on the limb at 8-month follow-up with optimal bone healing on radiographs. To the authors' knowledge, this is the first case report to describe a CaCL avulsion fracture repair with K-wires combined with a TPLO for a torn CrCL, with an excellent clinical outcome.

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.
