Article Synopsis
  • - The study aims to evaluate how six different proximal tibial osteotomies affect the geometry and alignment of canine tibias with varying degrees of tibial plateau angle (TPA).
  • - Thirty canine tibias were examined, categorized into three groups based on TPA, and simulated surgeries were assessed using orthopedic planning software to measure shifts in tibial structure after correction.
  • - Results showed that the TPLO/CCWO procedure led to minimal changes in tibial structure, while the coCBLO technique caused the most significant alterations; the mCCWO option effectively balanced geometry changes with osteotomy overlap preservation.

Objectives:  The purpose of this study was to evaluate a fluoroscopic method of angle of lateral opening (ALO) categorization based on identification of the visible portion of a pre-existing, circular recess within the metal shell of the BioMedtrix BFX acetabular component, which projects as an ellipse at clinically relevant ALO values. Our hypothesis was that there will be an association between the actual ALO and the categorization of ALO based on identification of the visible portion of the elliptical recess on a lateral fluoroscopic image at clinically relevant values.

Study Design:  A custom plexiglass jig was fitted with a two-axis inclinometer and a 24 mm BFX acetabular component attached to its tabletop.

Objective: To describe long-term outcomes of cats managed medically for cranial cruciate ligament disease (CCLD) via a validated owner-based questionnaire.

Animals: 18 client-owned cats.

Procedures: Retrospective review of medical records at 2 tertiary referral hospitals was conducted for records of cats diagnosed with CCLD for which medical management was pursued.

Objective: To compare the results of the measurement of femoral torsion using the axial measurement method on three-dimensional (3D) volumetric reconstructions of computed tomography images AMM(CT), the biplanar measurement method on 3D volumetric reconstructions of computed tomography images BMM(CT) and a reference standard using the axial measurement method on stereolithographic bone models AMM (SBM).

Study Design: Ex vivo study.

Sample Populations: Three-dimensional volumetric reconstructions of computed tomography images and stereolithographic bone models from 23 femurs of 14 dogs with hind limb lameness presented for orthopedic evaluation.

Objectives:  The aim of this study was to compare measurements of angle of lateral opening (ALO) and version determined using a radioopaque cup position assessment device imaged with fluoroscopy to measurements obtained by CT and direct measurement in a cadaveric model. Our null hypothesis was that there would not be any difference in the angles measured by the techniques.

Methods:  Six cadavers were implanted with BFX acetabular components.
