Abstract

OBJECTIVE:

To 1) assess the bending strength and stiffness of canine cadaver spines after fixation of a lumbar spinal fracture-luxation using a novel unilateral stabilization technique with pins and polymethyl methacrylate (PMMA) and 2) compare the results to a reference standard dorsal pin and PMMA technique.

STUDY DESIGN:

A randomized non-inferiority trial.

SAMPLE POPULATION:

Cadaveric lumbar spines (L1-L6) from 20 Greyhounds.

The purpose of this study was to evaluate short-term complications associated with the tibial plateau leveling osteotomy (TPLO) procedure in dogs of small and medium sizes. These study findings could then be compared with similar studies in dogs of all sizes. Ninety-eight procedures (82 dogs) using 2 or 2.7 mm TPLO plates were included spanning a 6 yr period with a minimum of an 8 wk follow-up period. The overall complication rate was 36%.

OBJECTIVE:

Describe optimal corridors for mediolateral or lateromedial implant placement in the feline tarsus and base of the metatarsus.

METHODS:

Computed tomographic images of 20 cadaveric tarsi were used to define optimal talocalcaneal, centroquartal, distal tarsal, and metatarsal corridors characterized by medial and lateral insertion points (IP), mean height, width, length and optimal dorsomedial-plantarolateral implantation angle (OIA).

OBJECTIVES:

To determine whether the addition of recombinant human bone morphogenetic protein (rhBMP-2) to a self-crosslinkable cellulosic hydrogel/biphasic calcium phosphate (BCP) granules construct promotes bone healing in critical-size ulnar defects in dogs.

OBJECTIVES:

To compare the bending and torsional mechanical properties of mono- and bicortical locking screws in a canine cadaveric tibial gap ostectomy bridged by a locking compression plate (LCP).

Journal: VCOT

OBJECTIVES:

The purpose of this study was to compare the stiffness, yield load, ultimate load at failure, displacement at failure, and mode of failure in cantilever bending of locking compression plates (LCP) and dynamic compression plates (DCP) in an acute failure ilial fracture model. Our hypothesis was that the LCP would be superior to the DCP for all of these biomechanical properties.

OBJECTIVE:

To compare the ability of the Tightrope® (TR) cranial cruciate ligament (CCL) technique, percutaneous lateral fabella suture (pLFS) technique, and normal CCL to control cranial tibial translation (CTT).

STUDY DESIGN:

In vitro biomechanical study.

SAMPLE POPULATION:

Cadaveric canine pelvic limbs (n = 18 pairs).

OBJECTIVE:

To compare the biomechanical properties of a 10-hole 3.5 mm locking compression plate (LCP) with 2 proximal and 2 distal bicortical locked screws reinforced with either a Steinmann pin of 30-40% the medullary diameter or a poly-ether-ether-ketone (PEEK) rod of ∼75% the medullary diameter in a cadaveric tibia gap model.

STUDY DESIGN:

Ex vivo study.

SAMPLE POPULATION:

Cadaveric canine tibias (n = 8 pair).
