Authors: Sanchez Villamil C, Phillips ASJ, Pegram CL, O'Neill DG, Meeson RL

OBJECTIVE: To report the prevalence, configuration, risk factors, fixation methods and outcomes after repair of humeral condylar fractures (HCF) in dogs.

STUDY DESIGN: Retrospective nested cohort study.

SAMPLE POPULATION: One hundred twelve dogs.

OBJECTIVE: The aim of this article was to report the surgical technique and clinical outcome of a modified cross-pin technique for the treatment of distal tibial physeal fractures in cats without postoperative external coaptation.

STUDY DESIGN: This study was a retrospective clinical study.

OBJECTIVE: To determine the effects of 2 augmentation techniques on the mechanical properties of titanium cannulated bone screws.

OBJECTIVE: The purpose of this study was to compare the load at failure and mode of failure of four constructs used to stabilize a tibial tuberosity osteotomy, including two vertically aligned pins (V), two horizontally aligned pins (H), two vertically aligned pins with a tension band wire (V-TB) and two horizontally aligned pins with a tension band wire (H-TB).

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.

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.

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.

OBJECTIVE: To report long-term outcomes of dogs treated with pantarsal arthrodesis (PTA) with medial plate fixation without external coaptation.

STUDY DESIGN: Retrospective case series.
