BACKGROUND: Diagnostic imaging is essential to assess the lame patient; lesions of the elbow joint have traditionally been evaluated radiographically, however computed tomography (CT) has been suggested as a useful technique to diagnose various elbow pathologies. The primary objective of this study was to determine the sensitivity and specificity of CT to assess medial coronoid disease (MCD), using arthroscopy as gold standard. The secondary objective was to ascertain the radiographic sensitivity and specificity for MCD compared with CT.

Medial compartment erosion is an advanced stage of medial coronoid disease, an important cause of elbow lameness in dogs, with treatment and the expected prognosis depending on the extent of the cartilage lesions. The identification of specific computed tomographic (CT) findings might facilitate the nonsurgical diagnosis and add to treatment decision making. Aims of this retrospective, analytical, method comparison study were to describe CT findings in elbows of dogs arthroscopically diagnosed with medial compartment erosion and to compare CT vs. arthroscopic findings.

OBJECTIVE: To describe the use of a video telescope operating monitor (VITOM™) for ventral slot decompression and to report its clinical applications using preoperative and postoperative computed tomography (CT) myelography.

STUDY DESIGN: Prospective case series.

ANIMALS: Consecutive dogs presented with cervical intervertebral disc disease requiring surgical decompression (n = 30).

OBJECTIVES: To describe clinical, radiographic, and magnetic resonance imaging (MRI) findings in 16 dogs diagnosed with gastrocnemius musculotendinopathy.

METHODS: Retrospective evaluation of medical records, radiographs, and MRI results, as well as follow-up completed by telephone questionnaire.

RESULTS: Most dogs had chronic hindlimb lameness with no history of trauma or athletic activities. Clinical examination revealed signs of pain on palpation without stifle joint instability. Seven dogs had radiographic signs of o

OBJECTIVE: To evaluate the usefulness of laser Doppler flowmetry (LDF) to measure surface blood flow in canine cruciate ligaments, compare measurements in different sites of intact and partially ruptured canine cranial cruciate ligaments (CrCL) and intact caudal cruciate ligaments (CaCL), and investigate any association between surface blood flow in partially ruptured CrCL and synovitis or duration of clinical signs.

STUDY DESIGN: Case-controlled clinical study.

ANIMALS: Sixteen dogs with partially ruptured CrCL and five dogs with intact CrCL.

OBJECTIVES: 1) To describe a radiographic method for determination of joint orientation lines and anatomical joint angles in orthogonal planes of feline radii; 2) to establish a range of normal radial joint orientation angles and anatomical axes in a feline population; and 3) to assess the repeatability and reliability of this methodology.

OBJECTIVES: To describe a protocol for the measurement of tibial rotational alignment using CT multiplanar reconstructions. To establish the feasibility of producing general guidelines for the amount of torsional contouring to apply to a bone plate applied to the medial aspect of the tibia during repair of a non-reducible tibial fracture.

OBJECTIVE: To use micro-computed tomography (CT) to evaluate the fissure-fracture pattern in dogs affected by medial coronoid disease (MCD).

STUDY DESIGN: Prospective case-controlled study.

SAMPLE POPULATION: Client owned (n = 21) and cadaver dogs (n = 5).

OBJECTIVE: To describe the effects of internal and external femoral rotation on radiographic measurements of the anatomical lateral distal femoral angle (a-LDFA) using two methods for defining the anatomical proximal femoral axis (a-PFA).

METHODS: Digital radiographs were obtained of 14 right femora at five degree intervals from 10° external rotation to 10° internal rotation. Using freely available software, a-LDFA measurements were made using two different a-PFA by a single observer on one occasion.
