A four-month-old West Highland White Terrier was presented to the Small Animal Teaching Hospital at the University of Liverpool with the complaint of a bilateral angular carpal deformity. A 20° valgus deformity was present in both thoracic limbs, centred on the distal radial physes. Both distal ulnas were grossly thickened and there was concomitant thickening of the rostral mandible and calvarium. The dog exhibited signs of resentment on palpation of the mandible and signs of pain were elicited on flexion and extension of both elbow joints.
Effects of antebrachial torsion on the measurement of angulation in the frontal plane: A cadaveric radiographic analysis.
Objectives: To quantify the effect of ante- brachial torsion on the miscalculation of radial valgus measured radiographically and to assess a radiographic positioning method used to mitigate torsion-associated artifactual miscalculation of concurrent frontal plane angulation. Methods: A canine cadaveric forelimb was used to model different combinations of valgus and external torsion. Valgus was induced in the limb in increments of five degrees, radiographic images were taken at each increment, and the observed radiographic valgus was measured.

Congenital limb deformities are rarely reported in the cat. The macroscopic and radiographic features of aphalangia are described in a 2-month-old male kitten showing a shortened limb that ended, at the level of the carpus, in a stump without digits. A nail was present at the level of the first phalanx and on the palmar surface only two footpads were present. The radiographs showed an absence of phalanges. The first metacarpal and the proximal and distal phalanges of digit 1 were present. The deformed metacarpal bones were reduced in length; the carpal bones were incompletely ossified.

A 4-month-old domestic shorthair female cat weighing 1.3 kg was presented for evaluation of respiratory distress. The animal showed evident dyspnoea with exercise intolerance and a marked concave deformation of the sternum. After measurements of the fronto-sagittal and vertebral indexes, the pectus was classified as moderate and surgery was elected. Surgical correction was performed using an open approach to the sternum with osteotomy of the last sternebra and costochondral junctions of the eighth and ninth ribs bilaterally.
Development and validation of a canine radius replica for mechanical testing of orthopedic implants.
Objective-To design and fabricate fiberglass-reinforced composite (FRC) replicas of a canine radius and compare their mechanical properties with those of radii from dog cadavers. Sample-Replicas based on 3 FRC formulations with 33%, 50%, or 60% short-length discontinuous fiberglass by weight (7 replicas/group) and 5 radii from large (> 30-kg) dog cadavers. Procedures-Bones and FRC replicas underwent nondestructive mechanical testing including 4-point bending, axial loading, and torsion and destructive testing to failure during 4-point bending.

To report clinical application of intraosseous transcutaneous amputation prosthesis (ITAP) for limb salvage.
Retrospective case series.
Client owned dogs with malignant neoplasia of the distal aspect of the limb.
The double-arch modified type-1b external skeletal fixator. Technique description and functional outcome for surgical management of canine antebrachial limb deformities.
To describe acute correction of antebrachial angular and rotational limb deformities (ARLD) using a new external skeletal fixator (ESF).
Radiographic evaluation of osteotomized ulnar segments following arthroscopic treatment for canine medial coronoid disease.
To assess movement of ulnar segments radiographically, following proximal and midshaft ulnar osteotomy or ostectomy after arthroscopic treatment for dogs diagnosed with medial coronoid disease.
Fragmentation and cartilage wear were treated arthroscopically and the presence of incongruity confirmed. Osteotomies were performed at the mid-point or proximal third of the length of the ulna. The distance of separation between the ulnar segments and the adjacent radius were measured and followed by serial radiographs postoperatively until healing had occurred.
Evaluation of the effect of computed tomography scan protocols and freeform fabrication methods on bone biomodel accuracy.
Objective-To assess the effect of computed tomography (CT) scan protocols (radiation amounts) and fabrication methods on biomodel accuracy and variability. Sample-Cadaveric femur of a Basset Hound. Procedures-Retroreconstructions (n = 158) were performed of 16 original scans and were visually inspected to select 17 scans to be used for biomodel fabrication. Biomodels of the 17 scans were made in triplicate by use of 3 freeform fabrication processes (stereolithography, fused deposition modeling, and 3-D printing) for 153 models.
