Objectives: To determine the reliability of early passive hip laxity examination in predicting moderate and severe hip dysplasia. Methods: The passive hip laxity of 104 Estrela Mountain dogs was evaluated using the Ortolani method, conventional hip-extended radiography and the PennHIP method, when the animals were between four and 12 months of age. After the age of one, dogs were re-examined for hip dysplasia using the Fédération Cynologique Internationale scoring system.
Early hip laxity examination in predicting moderate and severe hip dysplasia in Estrela Mountain Dog.
Proximal tibial epiphysiodesis to reduce tibial plateau slope in young dogs with cranial cruciate ligament deficient stifle.
The purpose of this study was to evaluate the ability of proximal tibial epiphysiodesis to reduce the tibial plateau slope in young dogs with cranial cruciale ligament (CCL) deficient stifles. Of the 14 treated dogs, eight had a bilateral injury, for a total of 22 joints. After physical and radiographical examination and measurement of tibial plateau slope, all of the dogs underwent surgery.
Comparison of conservative management and juvenile pubic symphysiodesis in the early treatment of canine hip dysplasia.
OBJECTIVES: To evaluate the efficacy of juvenile pubic symphysiodesis (JPS) in a clinical setting for the early treatment of canine hip dysplasia (CHD), and to identify its indications and contraindications. METHODS: The final degree of CHD using the FCI (Fédération Cynologique Internationale) CHD classification in 5 Grades (A, B, C, D, E) was assessed at skeletal maturity in two homogeneous groups of dogs assessed at the age of 14 to 22 weeks and selected according to their susceptibility to CHD; one group was treated with JPS and one group was conservatively managed.

OBJECTIVE: To develop and assess clinical outcomes for osteochondral autografting for treatment of stifle osteochondrosis (OC) in dogs. STUDY DESIGN: Retrospective case series. ANIMALS: Dogs with stifle OC (n=10). METHODS: Osteochondral autografting was developed and optimized in canine cadavers and purpose-bred research dogs using the Osteochondral Autograft Transfer System (OATS). Dogs with stifle OC (n=10 dogs, 12 stifles) were then treated using the OATS system.
A four-month-old German Shepherd Dog (GSD) was admitted with bilateral non-weight bearing hindlimb lameness and pyrexia. A diagnosis of bilateral distal femoral fractures secondary to metaphyseal osteopathy was made on the basis of clinical signs, radiography and biopsy. The dog returned to normal function following conservative management. As far as the authors are aware there are no previous reports of pathological fractures secondary to this condition.
An 11-month-old neutered female crossbreed dog was admitted with left pelvic limb lameness. Radiographs and computed tomography identified an osteochondritis dissecans- (OCD) like lesion in the intercondylar fossa of the femur originating from the axial aspect of the medial femoral condyle. Stifle arthrotomy was performed in order to remove the bony fragment. It was concluded that the clinical features and location of this lesion indicate an osteochondritis dessicans-like lesion.
An extensible internal device (EID) was developed to preserve growth plate during the treatment of fracture complications or segmental bone loss from tumour resection in children. Since this type of extensible, transphyseal, internal fixation device has only been used in a few paediatric cases; the aim of this study was to evaluate an in vivo canine study, a surgical application of this device, and its interference with longitudinal growth of the non-fractured distal femur.
Validation and application of a radioimmunoassay for ovine growth hormone in the diagnosis of acromegaly in cats.
Journal: Vet Rec
The validity of an ovine growth hormone (OGH) assay for the detection of feline growth hormone (FGH) was demonstrated by the parallel displacement of radiolabelled OGH by standard concentrations of OGH and serial dilutions of pooled FGH-rich serum. The minimum detectable limit of the assay was 1.67 microg/l.
Adactyly (terminal transverse hemimelia) is a rare condition in the cat. The clinical and radiographic findings in a one-year-old cat with bilateral hindlimb adactyly are described. The cat was treated conservatively and appeared to cope well with its deformity.

This report describes an autosomal incomplete dominant pattern of inheritance for osteochondrodysplasia in the Scottish Fold cats. A three-generation pedigree was analysed. Cats with folded ears were mated with cats with normal ears. All cats with folded ears, which were presumably heterozygous for the mutated allele, developed osteochondrodysplasia in distal fore- and hindlimbs but not in other bones, including the tail in which bone deformity had been demonstrated in previous studies.
