The goal of the study is to understand how the curing characteristics of a human bone cement (HBC) and veterinary bone cement (VBC) influence the mechanical behavior of each cement and cement bonding with an implant. This study hypothesizes that the curing temperature and time influence the mechanical properties of the cement adjacent to the implant, which resulted in the variability in bonding strength between the implant and cement.

Autologous bone remains the gold standard grafting substrate for bone fusions used for small gaps and critical defects. However, significant morbidity is associated with the harvesting of autologous bone grafts and, for that reason, alternative bone graft substitutes have been developed.

OBJECTIVE: To compare precorrectional and postcorrectional femoral alignment following distal femoral osteotomy using patient-specific 3-dimensional (3D)-printed osteotomy and reduction guides in vivo and ex vivo.

STUDY DESIGN: Prospective study.

OBJECTIVE: To describe and prospectively report outcomes associated with a novel minimally invasive percutaneous osteosynthesis (MIPO) technique for the treatment of humeral fractures in dogs and cats.

STUDY DESIGN: Prospective clinical case series.

Objectives  The purpose was to compare the biomechanical properties of a 1.5 mm locking compression plate (1.5 LCP) to the 1.5 mm straight plate (1.5 P), 1.5 mm straight plate stacked (1.5 PSt) and 2.0 mm straight plate (2.0 P) in compression and torsion. We hypothesized that biomechanical properties of the 1.5 LCP would be equivalent to properties of the 1.5 P and would represent an alternative for the treatment of radial fractures in miniature breed dogs in which those plates would be used.

OBJECTIVE: To determine the biomechanical properties of plating techniques for comminuted feline ilial fractures.

STUDY DESIGN: Ex vivo study on 40 paired feline hemipelves.

SAMPLE POPULATION: Forty paired fresh-frozen hemipelves that had been collected from 20 cats aged 2-6 years and weighing 4.0-5.5 kg.

OBJECTIVE: To determine the effect of the method used to attach OrthoFiber #5 to a 1/8-in Securos toggle rod on the mechanical properties of the resulting construct.

STUDY DESIGN: Prospective bench top mechanical analysis.

SAMPLE POPULATION: One hundred twenty-eight OrthoFiber #5-toggle rod suture constructs.

OBJECTIVE: This study evaluated the proficiency in executing closed, fluoroscopic-assisted reduction of unicondylar humeral fractures. The following were hypothesised: experienced surgeons would be highly successful in performing closed reduction; body weight, time to surgery and surgeon experience would influence the reduction method; and the reduction method would not affect technical aspects of the repair.

OBJECTIVES: To describe a surgical technique using bilateral twisted string-of-pearls locking plates for lumbosacral fracture-luxation in dogs and cats.

OBJECTIVE: To report the outcome of horses after pancarpal or partial carpal arthrodesis with 3 locking compression plates (LCP).

STUDY DESIGN: Case series.
