Objectives: The aim of this study was to define landmarks of the intermetatarsal channel of the dorsal pedal artery and to assess whether damage to the dorsal pedal artery during metatarsal screw placement in dogs undergoing pan- and partial-tarsal arthrodesis (PanTA/ParTA) could be a mechanism in the development of plantar necrosis.

Objective: To describe the application and early outcome of a custom-made unipolar partial tarsal replacement in a dog with an extensive medial talar ridge OCD.

Animal: A 7-month-old, 25 kg male Rhodesian Ridgeback with progressive left hindlimb lameness (grade III-IV/IV) and diagnosis of talar OCD.

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.
