OBJECTIVE:
To determine whether there is a difference between the ability of peak vertical force (PVF), vertical impulse (VI), and percentage body weight distribution (%BW(dist) ) in differentiating which leg is most affected by hip joint pain before total hip replacement (THR) surgery, and for measuring changes in limb use after THR surgery.
STUDY DESIGN:
Prospective clinical study.
ANIMALS:
Dogs (n = 47).
METHODS:

Objective: To describe the radiographic, ultrasonographic, computed tomography (CT), magnetic resonance imaging (MRI), and arthroscopic findings in eight dogs with elbow lameness caused by primary flexor enthesopathy. Study design: Clinical study. Animals: Eight client-owned dogs. Methods: In all dogs, lameness was localized to the elbow by clinical examination. Radiographic examination, ultrasound, CT and MRI were performed prior to arthroscopy. In seven dogs, surgical treatment and subsequent histopathology were performed.

Objectives: The primary objective was to determine the prevalence, spinal distribution, and association with the signalment of cats suffering from different grades of feline spondylosis deformans (spondylosis). The secondary objective was to document behavioural changes associated with spondylosis by owner observation. Methods: A cross-sectional study was performed to determine the prevalence of feline spondylosis (group 1).

OBJECTIVE:
To describe structural changes associated with osteoarthritis (OA) in cats and to quantify OA-associated disability using functional evaluations.
STUDY DESIGN:
Cross-sectional pilot study with longitudinal data.
ANIMALS:
Normal cats (n = 2) and coxofemoral joint OA cats (n = 4) were evaluated by physical examination, radiography, and magnetic resonance imaging (MRI).

OBJECTIVE:

OBJECTIVE:
To report arthroscopic findings in dogs with severe elbow incongruity combined with fragmented medial coronoid process (FCP) and compare these findings in normal joints and congruent joints affected by FCP.
STUDY DESIGN:
Clinical study.
ANIMALS:
Dogs with elbow lameness (n = 40) and purpose bred dogs (5; controls).

Objective
To assess survival times in dogs that received palliative radiation therapy (RT) alone, and in combination with chemotherapy, pamidronate, or both for primary appendicular bone tumors and determine whether the addition of these adjunctive therapies affects survival.
Study Design
Retrospective case series.
Animals
Dogs (n = 50) with primary appendicular bone tumors.

The objective of the study was to evaluate the efficacy and tolerability of robenacoxib, a selective cyclooxygenase-2 inhibitor, for the treatment of acute pain and inflammation associated with musculoskeletal disorders in cats. The study was a prospective, multi-centre, randomised, blinded, non-inferiority design clinical trial comparing robenacoxib to ketoprofen.

Objectives: To report the outcome of unilateral surgery, by a plantaromedial approach, in 15 Labrador Retrievers with osteochondrosis dissecans (OCD) of the medial trochlear ridge of the talus. To evaluate the influence on outcome of age at surgery, bilateral involvement, periarticular soft tissue increase (PSI), osteophyte size (OS), decrease of range of joint motion and follow-up. To assess the extent of tarsal hyperextension in the standing dog. Methods: A retrospective clinical and radiographic study was conducted and the post-treatment gait was analysed using a force plate.

A two-year-old, 97 kg, male neutered English Mastiff was evaluated for left pelvic limb lameness of five months duration localized to the stifle joint. Following radiographic, computed tomographic and arthroscopic examination, the lameness was subsequently diagnosed as being caused by primary synovial osteochondromatosis. In total, 194 osteochondral bodies were removed using arthroscopy in combination with a mini-arthro-tomy. Histology and immunohistochemistry of the loose osteochondral fragments confirmed the diagnosis with a moderately high degree of differentiation and low cellularity.
