Computed tomography or magnetic resonance imaging-assisted partial hoof wall resection for keratoma removal.

Objectives: To (1) describe the computed tomography (CT) and magnetic resonance imaging (MRI) appearance of keratomas; (2) describe a CT- or MRI-assisted partial hoof wall resection technique for removal of keratomas; and (3) evaluate the morbidity and postoperative outcome of these horses.

Study Design: Case series.

Animals: Horses (n=10) with keratoma.

Clinical relevance of abnormal scintigraphic findings of adult equine ribs.

Horses with cranial rib abnormalities may exhibit severe acute lameness and may have unusual gait deficits characterized by forelimb abduction during protraction at the walk. Horses with caudal rib abnormalities may resent being saddled and ridden. In a retrospective evaluation of 20 horses with a documented rib lesion, 25 sites of increased radiopharmaceutical uptake were found in one or more ribs.

Surgical repair of mid-body proximal sesamoid bone fractures in 25 horses.

Objective: To describe the characteristics of unilateral mid-body proximal sesamoid bone (PSB) fractures, to determine factors associated with the outcome of horses after surgical repair, and to describe a technique for arthroscopically assisted screw fixation in lag fashion.

Study Design: Retrospective case series.

Animals: Horses (n=25) with unilateral mid-body PSB fracture.
