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.
This report describes the treatment of severe procurvatum because of distal femoral physeal fracture malunion in two skeletally immature dogs.
Ectrodactyly is a rare developmental anom-aly of the distal part of the forelimb. It is characterized by the presence of an abnormal longitudinal soft tissue and osseous separation or cleft between the digits and the metacarpal bones. It can be associated with hypoplasia, aplasia and malformation of one or more bones of the antebrachium, carpus, metacarpus and digits. Unilateral ectrodactyly and moderate lameness were diagnosed in a young female dog. The dog was treated surgically with reconstruction of soft tissues and stabilization of the metacarpal bones by two nylon cerclage sutures.
Objective: To report the signalment and clinical features of dogs with non-traumatic lateral patellar luxation and to report the complications and outcomes following surgery. Methods: A multicentre retrospective study was performed. Medical records were reviewed and the signalment, clinical features, and treatment of dogs presenting with lateral patellar luxation were recorded. In dogs treated surgically, the outcome and complications were investigated. Results: Sixty-five dogs (95 stifles) were included; 39 were male and median age at presentation was 10 months.
Objectives: To measure lateral and medial tibial plateau angle values in isolated canine tibiae and to compare lateral and medial tibial plateau angle values between dogs based on sex and breed. Methods: Tibiae of 90 dogs from 24 different breeds were used. Photographs were taken of the medial and lateral aspects of the tibiae for measurement of the medial and lateral tibial plateau angles. Additionally, the medial tibial plateau angle was measured from radiographs of the tibiae.
Skeletal malocclusions may be due to disturbances in the growth of the mandible or maxilla. In most cases, discomfort is the result of tooth-to-tooth malocclusion or tooth-to-soft-tissue contact. Currently, in veterinary medicine, these problems are treated palliatively. In humans, orthognathic surgery is indicated to correct severe skeletal malocclusions, offering aesthetic and functional benefits to the patients. This research evaluated the effects of an intra-oral mandibular sagittal split osteotomy in 20 dog cadavers with skeletal malocclusion.
Four skeletally immature, small breed dogs (five elbows) with elbow incongruency were evaluated for forelimb lameness. Findings on clinical examination included pain, effusion and decreased range of motion of the affected elbow. Radiography, computed tomography and arthroscopy demonstrated elbow incongruency in all dogs. Fragmented medial coronoid process was diagnosed arthroscopically in three dogs (four elbows). Arthroscopic subtotal coronoidectomy was performed in all cases of fragmented medial coronoid process.
Objectives: To evaluate how the inclination and torsional deformity of the hemipelvis using extra-rotation as a model affect acetabular angle (AA) and dorsal acetabular rim angle (DARA) assessment with computed tomography (CT). Methods: A normal canine hemipelvis positioned in dorsal recumbency was scanned with a 16-slice multidetector CT scanner, with different degrees of torsional deformity, using extra-rotation around the long axis (0-5-10-15°) of the hemipelvis.
To assess the precision of a novel protocol for determination of femoral varus angle (FVA) using computed tomography (CT) in dogs, and to quantify the effect of femoral rotational and sagittal plane malpositioning on measured FVA.
Femora (n = 66) from dogs that had pelvic limb CT examination for patellar instability (26) or other reasons (10).
