The medical records of all cats with tarsocrural joint instability that were treated between June 2002 and December 2008 at the Royal Veterinary College were retrospectively reviewed. A total of 32 cats were identified. Information gathered included signalment, type of injury (subluxation or luxation), concurrent fractures, presence of soft tissue wounds, transarticular external skeletal fixation (TESF) type, configuration of TESF (number of pins proximal and distal to the joint), duration of hospitalisation, duration of TESF prior to removal, complications and cost.

Objectives: To determine observer agreement on radiographic evaluation of central tarsal bone (CTB) fractures and compare this with evaluation of the same fractures using computed tomography (CT). Methods: Radiographs and CT scans were obtained of the right tarsi from limbs of Greyhounds euthanatized after sustaining severe CTB fracture during racing. Four observers described and classified each fracture. Inter- and intra-observer agreements were calculated. Results: Inter-observer agreement was higher for assessment of fractures using CT.

Objectives: To evaluate the short- and long-term outcomes of surgically repaired Achilles tendons in cats. Methods: Twenty-one cats that underwent surgical repair of Achilles tendon injuries were retrospectively examined. Signalment, type of injury, time from injury to surgery, the surgical repair, complications, and long-term outcomes were recorded. Statistical comparisons were made between traumatic and atraumatic injuries using Student's paired t-tests. Results: Both traumatic and atraumatic causes of disruption were equally represented and female cats were significantly over-represented.

Forty-five cases of canine Achilles mechanism disruption were reviewed, mostly involving medium-sized dogs, among which dobermanns, labradors and border collies were most commonly represented. Most cases were acute in onset (66.7 per cent), and were usually closed injuries (75.6 per cent). In the majority of cases, the damage involved all tendons (26.7 per cent), all tendons except the superficial digital flexor tendon (22.2 per cent), or the gastrocnemius alone (20 per cent).

An eight-month-old, 31.2 kg, entire male Golden Retriever was presented for evaluation because it had a four-week history of right hindlimb lameness and audible popping occurring in association with movement of the right hindlimb. Mild right hindlimb lameness was noted upon gait analysis. Moderate to severe effusion and pain on extension were appreciated on palpation of the right tarsus.

OBJECTIVE: To compare mechanical stability between a novel polypropylene mesh repair (Mesh), a modified 3-loop pulley suture (Suture), and a combination of the techniques (Suture+Mesh) for the repair of distal canine Achilles' tendon ruptures. STUDY DESIGN: In vitro mechanical evaluation. SAMPLE POPULATION: Cadaveric canine Achilles' tendon/calcaneus units (n=34). METHODS: Constructs were loaded under tension to failure in a materials testing machine with synchronized kinematic analysis.

Objective: To describe the use of a single-ring transarticular fixator construct for use in immobilisation of the talocrural joint in order to protect the healing of surgical repair of ruptures of the common calcaneal tendon. Methods: Ten repairs were performed in nine dogs. The age, breed, sex, details about the duration of pre-existing lameness, and the location and severity of tendon rupture at presentation were recorded for each dog. Recheck examinations were performed at one, two, four, six, eight, and 12 weeks postoperatively.

Five cats were treated for a fracture of the medial malleolus, 10 for a fracture of the lateral malleolus and 15 for fractures of both malleoli. Open reduction and internal fixation with Kirschner wires (K-wires) with or without a tension band wire was applied to 26 of the fractures. Unilateral-uniplanar or bilateral-uniplanar transarticular external skeletal fixators were applied to provide coaptation in 19 cases and appeared to be well tolerated. In 24 cases fracture healing was assessed radiographically between four and eight weeks after treatment.

Currently, there are no available anatomic descriptions of the soft tissue structures that are visible with ultrasound in the canine tarsus. Eight cadaver hindlimbs and 10 clinically normal dogs (15-37 kg) were examined with ultrasound to establish which structures could be visualized in normal dogs. The structures always identified included the long digital extensor tendon, the tibialis cranialis tendon, the joint space, and the three bellies of the extensor digitum brevis muscle on the cranial/dorsal aspect of the tarsus.

This report describes the successful use of the novel fixed-angle locking plating system ALPS (advanced locking plate system) in the case of dorsal tarsometatarsal instability in a cat. Partial arthrodesis of the tarsometatarsal joint was performed with a two hole ALPS 5 and two 2.4 mm selftapping locking screws through a small dorsal approach. Five days after the surgery the cat was walking without lameness. Radiographs made after six weeks showed uneventful healing.
