Objective-To compare in vitro axial compression, abaxial compression, and torsional stiffnesses of intact and plated radii from small- and large-breed dogs. Sample-Radii from 18 small-breed and 9 large-breed skeletally mature dogs. Procedures-3 groups were tested: large-breed dog radii plated with 3.5-mm limited-contact dynamic compression plates (LCDCPs), small-breed dog radii plated with 2.0-mm dynamic compression plates (DCPs), and small-breed dog radii plated with 2.0/2.7-mm cut-to-length plates (CTLPs).
The medical records of three cats that were presented with severe carpal injury requiring radiocarpal arthrodesis were reviewed. Medial plating using the Compact 2.0 LOCK™ systema was performed in all three cases. Although screw positioning may be difficult because of the large distance between the holes of the plate and the relatively large size of screws, plate loosening or metacarpal fractures did not occur. Long-term clinical and radiographic follow-up (6 months to 4.5 years) revealed excellent outcome in two cats. In the third cat, the radiocarpal joint did not undergo complete fusion.
Treatment of fractures of the distal radius and ulna in toy breed dogs with circular external skeletal fixation: a retrospective study.
Objective: To evaluate the effectiveness of circular external skeletal fixation (CESF) in treating fractures of the distal radius and ulna in toy breed dogs, and to document the type and frequency of complications associated with this technique. Methods: The medical records of small breed dogs with fractures of the distal radius and ulna admitted to the University of Turin and to the Clinica Ferretti between 2002 and 2009 were retrospectively reviewed.
Carpal canal syndrome, or carpal tunnel syndrome, is the most common entrapment neuropathy in humans and is caused by compression of the median nerve as it courses through the carpal canal. A similar condition has been reported in horses, however there have not been any reported cases of a dog showing lameness secondary to compression within the carpal canal. This report describes the case of a dog exhibiting lameness secondary to a lipoma within the carpal canal. Lameness improved after surgical removal of the mass.
In vitro comparison of proximal ulnar osteotomy and distal ulnar osteotomy with release of the interosseous ligament in a canine model.
Journal: Vet Surg
Objective: To determine the effect of proximal ulnar osteotomy (PUO), distal ulnar osteotomy (DUO), and DUO with release of the interosseous ligament (DOLR) on displacement of the proximal ulna at the radioulnar joint. Study Design: Experimental mechanical study. Sample Population: Cadaveric, skeletally mature canine thoracic limb pairs (n=11). Methods: Thoracic limbs disarticulated at the elbow were randomly assigned to 1 of 2 groups: (A) limbs were tested with no treatment (NOTX), then with PUO; (B) limbs were tested with DUO followed by DOLR.
Vascularized ulnar bone grafts for limb-sparing surgery for the treatment of distal radial osteosarcoma.
The objective of this retrospective study was to compare vascularized free or roll-in ulnar bone grafts for limb-sparing surgery in dogs with radial osteosarcoma with the cortical allograft, metal endoprosthesis, or distraction osteogenesis techniques. Overall, the ulnar graft techniques used in this study demonstrated excellent healing properties. Complications included recurrence of the tumor in 25% (2/8) of the dogs, metastasis in 50% (4/8) of the dogs, implant loosening in 37.5% (3/8) of the dogs, implant failure in 12.5% (1/8) of the dogs, and infection in 62.5% (5/8) of the dogs.
Soft-tissue injuries associated with cast application for distal limb orthopaedic conditions. A retrospective study of sixty dogs and cats.
Objectives: Casts applied for orthopaedic conditions can result in soft-tissue injuries. The purpose of our study was to describe the nature and prevalence of such complications. Methods: We performed a retrospective review of medical records of dogs and cats that had a cast placed for an orthopaedic condition between October 2003 and May 2009. The data were analysed and categorised. Results: Of the 60 animals that had a cast placed, 63% developed a soft-tissue injury (60% mild, 20% moderate and 20% severe).
Improving surgical reduction in radial fractures using a ‘dowel’ pinning technique in miniature and toy breed dogs
Objectives: A retrospective approach was used to detail and evaluate a ‘dowel’ pinning technique in distal radial fractures in miniature and toy breed dogs. Methods: Medical records and radiographs from 2003–2009 of miniature and toy breed dog radial fractures were examined. Sixty cases were divided into two groups: 51 radial fractures repaired with a ‘dowel’ pinning and external skeletal fixation (ESF) and nine radial fractures repaired with closed reduction and ESF.
