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.

Objective: To describe the technique of combined center of rotation of angulation (CORA)-based leveling osteotomy (CBLO) with tibial tuberosity transposition (TTT) and to compare the load to failure between CBLO combined with TTT and CBLO or TTT alone.

Study design: Ex vivo study.

Sample population: Twelve pairs of cadaveric pelvic limbs.

Authors: Lindsay C Peterson, Stanley E Kim, Adam H Biedrzycki

Objective: To evaluate the effectiveness of a novel crescent-shaped tibial plateau-leveling osteotomy (TPLO) saw guide (crescent guide) to assist with saw control in novice participants.

Study design: Ex vivo study.

Sample population: Synthetic bones (n = 54) and medium sized dog pelvic limbs (n = 36).

Numerous animal and human studies have demonstrated the benefit of controlled interfragmentary motion on fracture healing. In this study, we quantified interfragmentary motion and load transfer in tibial fractures fixed using a novel intramedullary nail (IMN) that allows controlled axial motion.

Objective: The aim of this study was to report the clinical experience with fluoroscopically guided tibial apophyseal percutaneous pinning (TAPP) for tibial tuberosity avulsion fractures (TTAF).

Study design: This is a retrospective case series.

Authors: Federico Longo, Tommaso Nicetto, Antonio Pozzi, Barbara Contiero, Maurizio Isola

Objective: To describe a three-dimensional (3D) computed tomographic (CT) methodology to measure the tibial torsion angle (TTa) and to evaluate intrarater and interrater agreements and accuracy through comparison with anatomic measurements.

Study design: Ex vivo cadaveric study.

Sample population: Thirty-six tibiae from 18 dogs.

A 9-year-old spayed female Cane Corso dog was presented with a 1-week history of an acute right hind limb non-weight-bearing lameness. Six years previously, a right tibial tuberosity advancement (TTA) procedure had been performed.

Orthogonal radiographs of the right pelvic limb taken before presentation revealed a comminuted displaced mid-diaphyseal tibial fracture. An aggressive bone lesion with osteolysis and periosteal reaction of the proximal tibia were evident that were most consistent with a primary bone tumor.
