Objectives: The aim of this study was to investigate the kinetic and kinematic changes in the stifle after a modified tibial tuberosity advancement (TTA) with 9 and 12 mm cranialization of the tibial tuberosity in different standing angles.

Authors: Peter J Welsh, Devin J Thompson, Yi Chen, Lloyd V Smith, Adam M Nylund

Objective: To determine whether one larger or two smaller diameter pins used for tibial tuberosity avulsion fracture (TTAF) stabilization provides greater axial tensile strength and stiffness when subjected to monotonic mechanical load to failure in normal skeletally mature canine cadavers.

Study design: Paired ex vivo biomechanical study.

Sample population: Eleven pairs of adult cadaveric dog tibias.

The aim of this article was to report surgical and medical management, and to evaluate complications and outcome of dogs treated for refractory infection after tibial tuberosity advancement (TTA) with a one-stage revision surgery consisting of implant removal and replacement of a TTA cage. It was a retrospective case series.

Seven cases were included in this study. Loss of advancement of the tibial tuberosity or tibial crest fractures did not occur in any case.

Objective: The objective of this study was to evaluate the use of linear external skeletal fixation (ESF) applied using minimally invasive techniques in dogs and cats.

Study design: Retrospective study.

Animals: Forty-nine dogs and 6 cats.

Cryopreserved bone allografts(CBA) are susceptible to infection, nonunion, and late stress fracture. Although surgical revascularization by intramedullary implantation of an arteriovenous bundle (AV bundle) generates a neoangiogenic blood supply, there is potential for vascular ingrowth-mediated bone resorption to weaken the graft.

Objective: Our objectives were to report complications associated with stabilization of long-bone fractures in cats using a 3.5-mm titanium interlocking nail and to examine the influences of signalment, fracture type and fixation evaluations on the occurrence of complications.

Study design: Retrospective clinical study.

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.

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.

The purpose of this study was to report approaches to surgical and medical management of proximal tibial metaphyseal fractures (PTMF) and short-term case outcome.
