Fracture Fixation and Implants

Authors: Neil J Burton, Hannah Horsewill, Tim H Sparks, Ilaria Caruso

Objective: To design a precontoured plating system for humeral condylar fracture repair in spaniels with humeral intracondylar fissure (HIF) and quantify accuracy of fit of the system on 3D printed bone models.

Study design: Experimental on 3D printed models.

Objectives: To describe a computed tomographic (CT) methodology for planning the correction of femoral and tibial torsion and report the clinical outcomes after femoral (FDO) and tibial (TDO) detorsional osteotomy in dogs affected by torsion malalignment and patellar luxation (PL).

Study design: Multicenter retrospective study.

Animals: Eighteen client-owned dogs.

Authors: Joris Johannes et al.

Objective: The aim of this study was to report the short-term clinical and radiographic outcome for the treatment of femoral capital physeal fractures with cortical positional screws in cats.

Authors: William George Marshall et al.

Objectives: (1) To estimate the prevalence of delayed union, non-union and mal-union in canine fractures; (2) to describe fracture, demographic, and treatment characteristics for these outcomes; (3) to identify risk factors for delayed or non-union.

Study design: Retrospective study.

Sample population: Four hundred and forty two dogs (461 fractures).

Authors: John Hanlon, Caleb C Hudson, Alan S Litsky, Stephen C Jones

Objective: To assess the feasibility and mechanical stability of sacroiliac (SI) joint stabilization using 2 short 3.5 mm cortical screws, each spanning an average of 23% of the width of the sacral body.

Study design: Cadaveric experimental study.

Sample population: Twenty-four canine pelvis specimens.

Authors: Kevin A de Moya, Stanley E Kim, Laurent P Guiot

Objectives: To report the short-term clinical outcome and complications in dogs that underwent surgical repair of femoral capital physeal or neck fractures via fluoroscopic-guided percutaneous pinning (FGPP).

Study design: Retrospective case series.

Animals: Client owned dogs (n = 11) with femoral capital physeal or neck fractures (n = 13).

Authors: Maria Zurita, Andrew Craig

Practical relevance: Cats frequently present with diaphyseal fractures, which require treatment in order to achieve a good return to function. These fractures often occur due to significant trauma; for example, as a result of road traffic accidents, high-rise syndrome and dog bite wounds. The first priority is to ensure the patient is systemically well before embarking on any specific surgical treatment of a fracture.

Objective: To describe the mechanical characteristics of a novel angle-stable interlocking nail (NAS-ILN) and compare them to those of a locking compression plate (LCP) by using a gap-fracture model.

Study design: Experimental study.

Sample population: Synthetic bone models.

Authors: Aparna Arun, Stephanie J Park, Philippa R Pavia, Sarah R Kalafut, Erik Hofmeister

Objective: The aim of this study was to evaluate factors contributing to the need for non-elective explant following surgical repair of tibial tuberosity avulsion fractures.
