Fracture Fixation and Implants

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.

OBJECTIVE: To determine factors contributing to tibial tuberosity fracture (TTF) after tibial plateau leveling osteotomy (TPLO).

STUDY DESIGN: Retrospective case-control study.

ANIMALS: Dogs (n = 2490) with cranial cruciate ligament rupture that underwent 3000 TPLO surgeries.

OBJECTIVE: To report modification of the endoprosthesis surgical limb-salvage technique to treat a locally extensive osteosarcoma in a dog and associated functional outcome.

STUDY DESIGN: Clinical case report.

ANIMALS: One client-owned dog.

Objective: To determine the effects of 6 types of transarticular immobilization techniques on tibiotarsal joint angles during stimulated weight bearing.

Study design: Canine ex vivo biomechanical study.

Sample population: Canine cadaveric pelvic limbs (n = 15).

BACKGROUND: Cranial cruciate ligament rupture is the most frequent orthopedic disorder in human and animals. An array of surgical techniques have been described to stabilize the stifle joint in dogs, including intraarticular stabilization, extraarticular stabilization, and tibial osteotomy techniques. Tibial plateau leveling osteotomy and tibial tuberosity advancement with a lot of modifications are the most common.
