Fracture Fixation and Implants

Authors: Katherine M Neal, Hayley M Gallaher, Alexis Thompson, Mary D Kerby

Objectives: (1) To evaluate the accuracy of an aiming device on placement of humeral transcondylar screws compared to fluoroscopic methods. (2) To compare experience level on outcome.

Study design: Randomized, match pair, prospective ex-vivo study.

Sample population: A total of 68 dogs.

Authors: Lindsay A Parker, Alex D Bukoski, Cristopher Zelaya-Nunez, John R Dodam, Kelley M Varner, Bryan T Torres

Objective: To report the locoregional anesthesia and analgesia preferences of veterinary anesthesiologists for use in dogs undergoing a TPLO and determine any association with specialty college, time from board-certification, or employment sector.

Study design: Cross sectional study.

Sample population: Diplomates of the American (ACVAA) and European (ECVAA) Colleges of Veterinary Anesthesia and Analgesia.

Authors: Barbro Filliquist et al.

Objective: Determine whether dogs with well-functioning orthopedic metal implants can develop metal reactivity.

Sample: Client-owned dogs that had tibial plateau leveling osteotomy (TPLO) or total hip replacement (THR) implants for 12 months or more and control dogs with no implants.

Authors: Stavros Karydas, Alan Danielski

A seven-month-old male Shetland Sheepdog was presented for assessment of thoracic limb lameness of 3 weeks duration.

Objective: To describe and evaluate minimally invasive repair of acetabular fractures in dogs using plates contoured to 3D-printed hemipelvic models.

Study design: Ex vivo feasibility study and case report.

Sample population: Adult canine cadavers (n = 5); 8 year old male neutered Chihuahua.

Objectives: The aim of this study was to evaluate the effect of Kirschner wire insertion angle on the biomechanical characteristics following tibial tuberosity osteotomy fixation in dogs.

Authors: Haley Mascellino, Karl Maritato, Matthew Barnhart, Philip Kass

Objective: The aim of this study was to retrospectively evaluate the use, complications and outcomes of the Liberty Lock System (LLS) used to repair fractures in dogs and cats.

Methods: Medical records (October 2016-June 2019) of dog and cat fractures repaired with the LLS were reviewed. Data reviewed included signalment, fracture classification, complications and radiographic outcome.

Objectives: The aim of this study was to report the use, complications and perioperative outcome of locking compression plates (LCP) for acetabular fracture fixation in feline patients.

Authors: Zachary A Miller, Sady Y Cabrera, David Mason, Philip H Kass

Objective: To evaluate outcomes of tibial tuberosity avulsion fractures (TTAF) in dogs with implants left in situ past skeletal maturity and to compare clinical outcomes with published outcomes in dogs whose implants were removed 4 to 6 weeks postoperatively.

Animals: 47 client-owned dogs.

Authors: Logan M. Scheuermann, Stanley E. Kim, Daniel D. Lewis, Matthew D. Johnson, Adam H. Biedrzycki

Objective Assess the accuracy and efficiency of reduction provided by application of plates precontoured to 3-dimensional (3D)-printed femoral bone models using a custom fracture reduction system (FRS) or intramedullary pin (IMP) to facilitate femoral minimally invasive plate osteosynthesis (MIPO) in dogs.

Study design Experimental cadaveric study.
