Fracture Fixation and Implants

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.
