Even though radiography is one of the most frequently used imaging techniques for orthopaedic disorders, it has been demonstrated that the interpretation can vary between assessors. As such, the purpose of this study was to examine the intraobserver and interobserver agreement and the influence of level of expertise on the interpretation of radiographs of the stifle in dogs with and without cranial cruciate ligament rupture (CCLR).

OBJECTIVES: To evaluate the reliability of CT measurement of canine elbow axial radioulnar congruence using a duplicated circle superimposition technique.

The formulation of appropriate postoperative strategies, following fracture repair, currently involves an understanding of radiological and clinical outcome measures. This study has evaluated several modalities used to assess the progression of bone healing in a sheep tibial segmental defect model.
OBJECTIVE: To describe a technique and normal findings for arthroscopy of the stifle in rabbits.
STUDY DESIGN: Cadaver study.
ANIMALS: Twenty cadaveric stifles from New Zealand White rabbits were examined.
METHODS: The arthroscope was placed through a medial portal, and instrument portals were created on the lateral aspect of the joint. The same portals were used for examination of the entire joint and palpation of structures with a probe.
Detection and accurate classification of traumatic tarsal fractures are important for identifying cases requiring surgical intervention. The aim of this prospective, experimental, methods comparison study was to directly compare the accuracy, sensitivity, and specificity of tarsal computed tomography (CT), ten-view and two-view digital radiographs for detecting traumatic fractures of the canine tarsus.

Canine cranial cruciate ligament rupture is often bilateral and asymmetrical, ranging from partial to complete rupture. The purpose of our diagnostic accuracy study was to assess the accuracy of 3 Tesla magnetic resonance imaging (MRI) detection of fiber loss and use of a visual analog scale in the diagnosis of complete versus partial cranial cruciate ligament rupture in 28 clinical dogs with unilateral complete rupture and contralateral partial rupture.

OBJECTIVE: To describe the arthroscopic appearance of intra-articular structures mid-term (9 months) and long-term (>12 months) after CORA-based leveling osteotomy (CBLO).
STUDY DESIGN: Case series.
ANIMALS: Dogs (n = 41) with second-look arthroscopy of the stifle after CBLO for treatment of a cranial cruciate ligament (CCL) deficiency. Both stifles were re-evaluated (stifles n = 42) in 1 dog.

Computed tomographic analysis of ventral atlantoaxial optimal safe implantation corridors in 27 dogs
OBJECTIVES: Ventral atlantoaxial stabilization techniques are challenging surgical procedures in dogs. Available surgical guidelines are based upon subjective anatomical landmarks, and limited radiographic and computed tomographic data.
OBJECTIVES: To evaluate the intra- and inter-observer measurement variability of an existing osteoarthritis (OA) stifle scoring system.
METHODS: Paired caudocranial and mediolateral canine stifle radiographs were selected randomly. A total of 15 assessment points were evaluated independently and graded twice (integer numeric scale: 1-4) at an interval of 2 weeks by three observers with different levels of experience. The grades for each of the 15 factors were summed to obtain the OA score for each patient.

Atlanto-axial (AA) instability due to ligament insufficiency is a common cause of cervical spinal cord compression in toy breeds. However, in some dogs a difference in size between the atlas and the axis leads to joint incongruence that exacerbates AA subluxation and makes surgical treatment challenging.
