OBJECTIVE To compare the biomechanical properties and gapping characteristics following loop modification of a 3-loop-pulley (3LP) pattern in an ex vivo canine common calcaneal tendon (CCT) avulsion repair model.

SAMPLE 56 skeletally mature hindlimbs from 28 canine cadavers.

Objective: To biomechanically evaluate an ultrahigh-molecular-weight polyethylene (UWMWPE) suture for temporary tarsocrural immobilization as a potential alternative to the existing surgical method, which uses a 4.5 AO/ASIF calcaneotibial cortical screw.

Study design: Randomized in vitro biomechanical study.

Case description: A 5-year-old 4.0-kg (8.8-lb) castrated male domestic shorthair cat was referred because of grade 4/5 left hind limb lameness and swelling in the region of the second metatarsal bone of that limb.

Clinical findings: Computed tomography revealed an expansile osteolytic lesion of the second metatarsal bone associated with a periosteal reaction on the third metatarsal bone. There was no evidence of metastases.
