Introduction: Partial resurfacing of the humeral head has been reported in humans to treat humeral osteochondritis dissecans. The aim is to describe a custom-made humeral resurfacing prosthesis for treatment of severe humeral head osteochondritis disse-cans in a dog. Case report: A seven-month-old female entire St. Bernard dog was presented with a 10 week history of severe left thoracic limb lameness. Radiography, arthroscopy and magnetic resonance imaging confirmed an extensive osteochondritis dissecans lesion affecting the caudal, medial and central regions of the humeral head.

A case of non-syndromic, complete syndactyly involving all four limbs is described in a three-month-old male crossbreed dog for the first time.Syndactyly is a rare condition in most animal species, in dogs it has been infrequently reported. Findings of clinical, radiographic and cytogenetic analyses are described and demonstrate probably for the first time that numerical and structural chromosome aberrations are not involved in the pathogenesis of this case of syndactyly.
Radiographic changes of the pelvis in Labrador and Golden Retrievers after juvenile pubic symphysiodesis. Objective and subjective evaluation.
Objectives: The hypothesis of this study was that juvenile pubic symphysiodesis (JPS) results in pelvic changes that can be identified radiographically in adult dogs. Methods: The medical records at the Clinica Veterinaria Vezzoni were searched for standard ventro-dorsal views of the pelvis of adult Labrador and Golden Retrievers that had undergone JPS or had not undergone surgery. The objective assessment of radiographs included the analysis of various pelvic measurements.
Avulsion fragmentation of the tibial tuberosity apophysis and associated patellar tendon enthesopathy in a skeletally immature dog.
A 9.5-month-old, female entire, 31.3 kg crossbred dog was presented with a 12 week history of moderate weight-bearing right pelvic limb lameness. Radiographic, computed tomographic, and ultrasonographic imaging revealed progressive avulsion fragmentation of the right tibial tuberosity apophysis and a patellar tendon insertional enthesopathy without physeal involvement. Conservative management was successful in achieving a good clinical outcome.
Minimally displaced tibial tuberosity avulsion fracture in nine skeletally immature large breed dogs.
Objective: The objective of this study was to describe the clinical and radiographic features, as well as the treatment and outcome of minimally displaced tibial-tuberosity-avulsion-fractures (MDTTAF). Materials and methods: Signalment, history, diagnostics, therapy, and outcome were recorded. Follow-up was documented as re-examination, radiographic assessment or telephone conversation. Results: Nine large breed dogs that were presented with lameness originating from the proximal tibia were included. All showed signs of pain when pressure was applied to the tibial tuberosity.
A 26-week-old female Boerboel was referred for evaluation of progressive left thoracic limb lameness. Computed tomography and radiographic evaluation revealed radiolucency of the caudal region of the proximal humeral metaphysis, absence of the humeral head, and gross distortion of the glenoid. Given the severe glenohumeral deformation, arthrodesis of the left shoulder was performed using orthogonal locking bone plates, lag screw fixation, and bone grafting. Despite late implant failure, arthrodesis was successful in this case, and satisfactory limb function was restored.
To evaluate dogs diagnosed with slipped femoral capital epiphysis which were treated by total hip replacement.
Clinical and radiographic records of consecutive cases of slipped femoral capital epiphysis treated by total hip replacement were reviewed. Longer-term follow-up was by owner questionnaire.

Two kittens aged between four and five months were presented having sustained patellar fractures. In both cases, healing was subsequently documented radiographically; this has not been reported previously in the literature. One kitten had bilateral patellar fractures - the symptomatic right stifle was treated with a pin and tension-band-wire which later failed, at which point partial patellectomy was performed. The fracture of the left patella was minimally displaced and was treated conservatively.
A 10-month-old Yorkshire Terrier was referred for evaluation of an intermittent right thoracic limb lameness that acutely progressed to non-weight-bearing. A diagnosis of bilateral bone cysts of the humeral condyles with a pathologic fracture of the lateral aspect of the right humeral condyle was given following radiographic and histopathologic examination. Bilateral pathology necessitated consideration of treatment modalities other than amputation of the limb, as previously reported. Arthrodesis of the right elbow using a 2.0 mm locking bone plate was performed.
