Fracture Fixation and Implants

OBJECTIVES: This article aimed to describe olecranon fracture in dogs and cats and their stabilization with tension band wiring or plate osteosynthesis, and to evaluate complications associated with each technique.

METHODS: Medical records of cats and dogs that had been surgically treated for olecranon fractures with either tension band wiring or plate osteosynthesis were retrospectively reviewed. The surgical technique, complications and long-term outcomes were assessed.

OBJECTIVE: To describe a novel Sacroiliac Luxation Instrument System (SILIS™) and its application in minimally invasive osteosynthesis (MIO) of sacroiliac luxations/fractures (SIL/F). The SILIS was designed to provide stable SIL/F reduction and accurate sacral screw placement while reducing personnel exposure to ionizing radiation during intraoperative fluoroscopy.

STUDY DESIGN
: Descriptive, proof of concept cadaveric study.

OBJECTIVES: Retrospective evaluation of repairing distal radial and ulnar fractures in small breed dogs with the Synthes 1.5-mm locking Adaption plate system and compare results in a similar group of patients repaired with the Synthes 2.0-mm limited contact-dynamic compression plate (LC-DCP).

OBJECTIVES: To assess screw loosening and pelvic narrowing following the use of locking implants to stabilise ilial body fractures in cats and small dogs.

METHODS: Review of clinical records and post operative and follow up radiography of 12 cats and five small dogs to evaluate accuracy of fracture reduction, screw purchase and subsequent screw loosening and reduction in pelvic diameter.

RESULTS: No screw loosening or reduction in pelvic diameter was observed at follow up.

OBJECTIVE: To report the outcome of mandibular body fractures treated with a wire-reinforced interdental composite splint (WRICS) in small breed dogs.

STUDY DESIGN: Retrospective case series.

OBJECTIVE: To determine the accuracy and safety of pin placement for lateral vertebral stabilization to the reference dorsal stabilization.

STUDY DESIGN: A randomized noninferiority trial.

SAMPLE POPULATION: Twenty Greyhound cadaveric lumbar spines (L1-L6).

OBJECTIVE: To determine whether 2.0 mm cancellous screws are superior to 2.0 mm cortical screws when inserted into cancellous and bicortical bone.

STUDY DESIGN: Biomechanical study.

This retrospective study evaluated complication rates for radius and ulna fractures in small breed dogs in which 1.5 mm to 2.7 mm cuttable bone plates were used for internal fixation. The medical records of all cases from 2004 to 2011 that were presented to our clinic were reviewed. Inclusion criteria were: dogs with body weight < 9 kg, fracture of the radius and ulna with open reduction, and internal fixation utilizing a cuttable bone plate. T

OBJECTIVE: To compare the biomechanical properties of using an interfragmentary 1.6 mm Kirschner wire or a 2.7 mm reconstruction plate as adjunctive epicondylar stabilization in simulated comminuted lateral unicondylar humeral fractures stabilized with a transcondylar 4.5 mm cortical screw.

STUDY DESIGN: Cadaveric biomechanical assessment.

SAMPLE POPULATION: Paired humeri harvested from 9 young, skeletally mature dogs.

OBJECTIVE: To investigate the feasibility of placing bi-cortical cortex (B-cort) or mono-cortical locking screws (M-lock) in a plate-rod construct applied to the feline tibia in combination with different intramedullary (IM) pins.
