Fracture Fixation and Implants

Early changes in serum osteocalcin and body weight are predictive of implant fixation in a rat model of implant loosening
Authors: Wilson BM, Moran MM, Meagher MJ, Ross RD, Mashiatulla M, Virdi AS, Rick Sumner D

OBJECTIVE Biomarkers are of interest to identify patients at risk for peri-implant osteolysis and aseptic loosening. We used a rat model of particle-induced peri-implant osteolysis to investigate if early changes in biomarkers were associated with subsequent implant fixation strength.

Mechanical comparison of two small interlocking nails in torsion using a feline bone surrogate
Authors: Marturello DM, von Pfeil DJF, Déjardin LM

OBJECTIVE: To compare the torsional behavior of two small angle-stable interlocking nails (I-Loc and Targon) with that of locking compression plates (LCP). To evaluate the effect of implant removal on the torsional strength of feline bone surrogates.

STUDY DESIGN: Experimental.

SAMPLE POPULATION: Fracture gap constructs and intact explanted bone surrogates.

Biomechanical Comparison of Two Locking Plate Constructs for the Stabilization of Feline Tibial Fractures
Authors: Hottmann NM, Johnson MD, Banks SA, Tuyn D, Lewis DD

Objectives The aim of this study was to compare the biomechanical characteristics of locking compression plate (LCP) and conical coupling plate (CCP) constructs for the stabilization of experimentally induced gap fractures in cat tibiae.

Comparison of temporary epiphysiodesis with RigidTacks TM and Blount-Staples in a porcine animal model using MRI
Authors: Hillebrand H, Sattelberger J, Gosheger G, Frommer A, Moller-Madsen B, Rahbek O, Gottliebsen M, Abdul-Hussein Abood A, Roedl R, Vogt B

RigidTackTM is a newly developed implant for total temporary epiphyseodesis. The implant combines the technical advantages of the traditionally used rigid Blount-staples and the newer flexible eight-platesTM.

Influence of administration of antimicrobial medications after TPLO on surgical site infections: A retrospective study of 308 dogs
Authors: Clark AC, Greco JJ, Bergman PJ.

OBJECTIVE: To determine the influence of prophylactic administration of oral antimicrobial medications after tibial plateau leveling osteotomy (TPLO) on surgical site infections (SSI) and antimicrobial

Mechanical Performance of a Polyaxial Locking Plate and the Influence of Screw Angulation in a Fracture Gap Model
Authors: Kaczmarek J, Bartkowiak T, Schuenemann R, Paczos P, Gapinski B, Bogisch S, Unger M

OBJECTIVE: The aim of this study was to compare the locking compression plate (LCP) with polyaxial locking system (PLS) using single cycle to failure 4-point bending test and to investigate the behaviour of PLS with screws inserted mono- and polyaxially using cyclic fatigue test in two bending directions.

Effect of orthopedic implants on canine long bone compression stiffness: a combined experimental and computational approach
Authors: Laurent CP, Böhme B, Verwaerde J, Papeleux L, Ponthot JP, Balligand M.

Osteosynthesis for canine long bones is a complex process requiring knowledge of biology, surgical techniques and (bio)mechanical principles. Subject-specific finite element analysis constitutes a promising tool to evaluate the effect of surgical intervention on the global properties of a bone-implant construct, but suffers from a lack of validation.

Risk of infection after double locking plate and screw fixation of TPLO in dogs weighing greater than 50 kilograms
Authors: Tuan J, Solano MA, Danielski A.

OBJECTIVE: To compare surgical site infection (SSI) rates after double locking plate and screw fixation (DLP), standard locking plate and screw fixation (LP), and conventional nonlocking plate and scre

Safety and Accuracy of Minimally Invasive Long Bone Fracture Repair Using a 2.5-mm Interlocking Nail: A Cadaveric Feline Study
Authors: Nabholz K, Pozzi A, Schmierer PA, Smolders LA, Knell SC1

OBJECTIVES: The Targon Vet System (TVS) is a 2.5-mm interlocking nail that can be applied minimally invasively. The purpose of this study was to test if the TVS could be safely applied percutaneously to different feline long bones without fluoroscopic guidance.
