Fracture Fixation and Implants

OBJECTIVE: To determine outcomes and complication rates of open reduction and cranial bone plate fixation of fractures involving the distal aspect of the radius and ulna in miniature- and toy-breed dogs. DESIGN Retrospective case series.

ANIMALS: 102 miniature- and toy-breed dogs (105 fractures) weighing ≤ 7 kg (15.4 lb) that had undergone open reduction and cranial bone plate fixation of a fracture involving the distal aspect of the radius and ulna from 2008 through 2015.

OBJECTIVES: The objective of this study was to quantify complications associated with external skeletal fixators (ESFs) in cats and to identify potential risk factors.

METHODS: A retrospective review of medical records and radiographs following ESF placement was performed.

OBJECTIVE: To determine outcome and prognostic factors after radius and ulna fracture repair with a modified IMEX miniature circular external skeletal fixation (MCESF) in small and toy breed dogs.

STUDY DESIGN: Retrospective study.

SAMPLE POPULATION: Thirty-seven young small and toy breed dogs with 41 radial and ulnar fractures.

OBJECTIVE: To evaluate the torsional properties of the Targon® Vet Nail System (TVS) in small canine femurs and to compare these properties to those of the 2.4 mm LC-DCP® plates.

OBJECTIVES: To report the use of compression resistant matrix (CRM) infused with recombinant human bone morphogenetic protein (rhBMP-2) prospectively in the healing of nonunion long-bone fractures in dogs.

METHODS: A longitudinal cohort of dogs that were presented with nonunion fractures were classified and treated with CRM soaked with rhBMP-2 and fracture fixation. They were followed with serial radiographs and evaluated for healing times and complications according to the time frame and definitions previously established for orthopaedic clinical cases.

OBJECTIVE: To assess technical feasibility and mechanical properties of 3 locking plate designs (Zero-P, Zero-P VA, and Uniplate 2) for use in the canine cervical spine.

STUDY DESIGN: Prospective ex vivo study.

ANIMALS: Cadaver cervical spines from skeletally mature large breed dogs (n = 18).

OBJECTIVE: To describe early clinical experience with a newly designed interlocking nail system (Targon(®) Vet) in diaphyseal fractures in cats and small dogs.

STUDY DESIGN: Retrospective case series.

ANIMALS: Client-owned cats (n=49) and dogs (n=8).

OBJECTIVES: To evaluate the use of Kirschner wires for treatment of fractures of the lateral aspect of the humeral condyle in growing dogs.

OBJECTIVE: To determine the stiffness and load to failure of two different ostectomy configurations using canine mandibles.

STUDY DESIGN: Cadaveric biomechanical assessment.

OBJECTIVE: To compare the biomechanical properties of 2 veterinary locking plates and monocortical screws/polymethylmethacrylate (PMMA) fixation in canine cadaveric cervical vertebral columns.

STUDY DESIGN: Biomechanical cadaveric study.
