High density infill in cracks and protrusions from the articular calcified cartilage in osteoarthritis in standardbred horse carpal bones.

We studied changes in articular calcified cartilage (ACC) and subchondral bone (SCB) in the third carpal bones (C3) of Standardbred racehorses with naturally-occurring repetitive loading-induced osteoarthritis (OA). Two osteochondral cores were harvested from dorsal sites from each of 15 post-mortem C3 and classified as control or as showing early or advanced OA changes from visual inspection. We re-examined X-ray micro-computed tomography (µCT) image sets for the presence of high-density mineral infill (HDMI) in ACC cracks and possible high-density mineralized protrusions (HDMP) from the ACC mineralizing (tidemark) front (MF) into hyaline articular cartilage (HAC).

Fragmentation of the proximal tubercle of the talus in horses: 9 cases (2004-2010).

Objective: To identify the prevalence of fragmentation of the proximal tubercle of the talus (FPTT) in a hospital population of horses, characterize the anatomic features of the affected area and fragments, and describe clinical findings, diagnosis, treatment, and outcome for horses with FPTT.

Design: Retrospective case series.

Animals: 9 horses with FPTT.

Equine articular synovial cysts: 16 cases.

Objective: To report the clinical findings, diagnosis, treatment and outcome of equine patients with articular synovial cysts.

Study Design: Retrospective case series.

Animals: Horses (n = 16) with articular synovial cysts.

Treatment of epiglottic entrapment by transnasal axial division in standing sedated horses using a shielded hook bistoury.

Objectives: To report use of a shielded hook bistoury developed for correction of epiglottic fold entrapment in standing sedated horses.

Study Design: Prospective clinical study.

Animals: Standardbreds (n=8), 3-19 years of age.
