Fracture Fixation and Implants

OBJECTIVE: To determine the influence of low-intensity pulsed ultrasound (LIPUS) on radiographic healing and limb function after uncomplicated, stable osteotomies in dogs.

STUDY DESIGN: In vivo, prospective, randomized, double-blinded, placebo-control study.

SAMPLE POPULATION: Fifty client-owned dogs.

OBJECTIVES: To evaluate the clinical and radiographic outcomes following surgical stabilisation of ilial fractures in dogs and cats using a laterally applied Synthes TPLO locking compression plate.

OBJECTIVE: To determine the effects of low-level laser therapy (LLLT) on clinical outcomes in dogs with cranial cruciate ligament disease treated with tibial plateau leveling osteotomy (TPLO).

STUDY DESIGN: Randomized, placebo-controlled clinical trial. Owners and surgeons (care providers and assessors) were masked.

OBJECTIVE: To determine the influence of a stricter aseptic protocol on implant-associated infection (IAI) rates after tibial plateau leveling osteotomy (TPLO).

STUDY DESIGN: Retrospective cohort study.

SAMPLE POPULATION: Seven hundred three dogs (811 TPLO).

Objective: To investigate the influence of plate and screw hole position on the stability of simulated radial fractures stabilized with a 1.5 mm condylar locking compression plate (LCP).

Study Design: In vitro mechanical testing of paired cadaveric limbs.

Sample Population: Paired radii (n = 7) stabilized with a 1.5 mm condylar LCP with an open screw hole positioned either proximal to (PG), or over (OG), a simulated small fracture gap.

Peroneal neuropathy is one of the complications of orthopaedic leg lengthening. Methods of treatment include slowing of distraction and decompression both of which may lead to additional complications.

BACKGROUND: Cranial cruciate ligament rupture is a prevalent injury in dogs, and tibial plateau leveling osteotomy (TPLO) is one of the preferred surgical techniques. Surgical site infection is a possible complication following TPLO and measurement of serum acute phase proteins is suggested to be a way to early recognize and distinguish postoperative infectious complications from normal postoperative inflammatory conditions.

BACKGROUND: Alcohol consumption is a risk factor for impaired fracture healing, though the mechanism(s) by which this occurs are not well understood. Our laboratory has previously shown that episodic alcohol exposure of rodents negatively affects fracture callus development, callus biomechanics, and cellular signaling which regulates stem cell differentiation. Here, we examine whether alcohol alters chemokine expression and/or signaling activity in the mouse fracture callus during early fracture healing.

Polymethylmethacrylate (PMMA) is the most commonly used filler material that lacks biological properties and osteoconductivity or osteoinductivity. Platelet gel (PG) is a typical source of growth factors, cytokines and molecules efficient for bone formation and remodeling.

The aim of this study was to evaluate bone healing and regeneration of bone defect in rat model by combining PMMA with PG.

Aim: The current study was undertaken to evaluate the clinical efficacy of end-threaded intramedullary pinning for management of various long bone fractures in canines.
