A5-year-old, male castrated, domestic short hair cat was referred to the authors' clinic because of wound dehiscence and exposure of tendon stumps after tenorrhaphy of the Achilles tendon.

OBJECTIVE: To evaluate the use of a temporary calcaneo-tibial screw for stabilization of the tarsocrural joint in dogs with surgically treated collateral ligament injury.

OBJECTIVE: To estimate the prevalence of complications and describe the outcome associated with calcaneal fractures in non-racing dogs and in cats.

STUDY DESIGN: Retrospective multicenter clinical cohort study.

ANIMALS: Medical records of client-owned dogs and cats (2004-2013).

OBJECTIVE: To report our experience with the use of contoured mini circular transarticular external skeletal fixators for the management of traumatic tarsal luxations in 15 cats.

Fracture of the central tarsal bone is an uncommon injury in dogs and occurs predominantly in racing Greyhounds. To the authors' knowledge, this type of fracture has not been described previously in cats.

This case report describes a five-year-old Domestic Shorthair cat referred to the Centro Veterinario Luni Mare because of lameness, swelling and signs of pain in the right hindlimb caused by trauma. Clinical examination and diagnostic imaging revealed a right central tarsal bone fracture.

OBJECTIVES: To describe the normal anatomy of the soft tissues of the canine tarsus as identified on computed tomography (CT) and magnetic resonance imaging (MRI) and to evaluate specific MRI sequences and planes for observing structures of diagnostic interest.

STUDY DESIGN: Prospective descriptive study.

ANIMALS: Canine cadavers (n = 3).

OBJECTIVES:

To compare radiography and computed tomography (CT) for the evaluation of medullary cavity diameters of metacarpal and metatarsal bones in cats and to analyse their correlation with intramedullary pin size.

OBJECTIVE:

Describe optimal corridors for mediolateral or lateromedial implant placement in the feline tarsus and base of the metatarsus.

METHODS:

Computed tomographic images of 20 cadaveric tarsi were used to define optimal talocalcaneal, centroquartal, distal tarsal, and metatarsal corridors characterized by medial and lateral insertion points (IP), mean height, width, length and optimal dorsomedial-plantarolateral implantation angle (OIA).

RESULTS:

A four-year-old, male Cocker Spaniel was presented for investigation of pelvic limb stiffness. There was palpable effusion of both tarsi, and analysis of synovial fluid from these joints indicated previous haemorrhage. After further investigation a diagnosis of idiopathic immune-mediated thrombocytopenia was made. The dog responded to treatment with prednisolone and azathioprine. To the authors' knowledge, this is the first reported case of confirmed haemarthrosis as the sole presenting clinical sign for canine idiopathic immune-mediated thrombocytopenia.

OBJECTIVE:
To evaluate the technical feasibility, efficacy and potential soft tissue damage of a joint distraction technique to facilitate arthroscopy of the tibio-tarsal joint and to test the effect of joint venting on the maximum distraction achieved.
