Musculoskeletal problems associated with lameness and poor performance in cutting horses: 200 cases (2007-2015).

OBJECTIVE To describe the chief complaints by owners and the types and prevalences of musculoskeletal problems associated with lameness or poor performance in cutting horses. DESIGN Retrospective case series. ANIMALS 200 client-owned cutting horses examined at the Texas A&M University Veterinary Medical Teaching Hospital between January 1, 2007, and December 31, 2015, because of lameness or poor performance.

Enthesopathy and desmitis of the medial collateral ligament of the cubital joint in 4 horses.

Case Description: 4 horses with enthesopathy and desmitis of the medial collateral ligament of the cubital joint were examined.

Clinical Findings: All 4 horses had a history of acute, severe, unilateral forelimb lameness and had signs of pain during manipulation of the affected upper forelimb; 2 also had swelling in the axillary region. There was no improvement in lameness after diagnostic local analgesia below the carpal region, and 1 of 4 horses had mild improvement after cubital joint analgesia.

Tendinitis of the proximal aspect of the superficial digital flexor tendon in horses: 12 cases (2000-2006).

Objective: To determine clinical signs, ultrasonographic findings, and outcome of horses with tendinitis of the proximal portion of the superficial digital flexor tendon (SDFT; group A horses) and to compare signalment, horse use, and outcome in these horses with that of horses with tendinitis of the midmetacarpal region of the SDFT (group B horses).

Design: Retrospective case series.

Animals: 12 group A horses and 22 group B horses.

Fractures of the tuber coxa of the ilium in horses: 29 cases (1996-2007).

Objective: To determine history; clinical, radiographic, ultrasonographic, and scintigraphic abnormalities; treatment; and outcome in horses with tuber coxae fractures and to describe a useful technique for obtaining a dorsomedial-ventrolateral 50 degrees oblique radiographic view of the tuber coxa of the ilium in standing horses.

Design: Retrospective case series.

Animals: 29 horses with fractures of tuber coxa.

Fractures of the greater tubercle of the humerus in horses: 15 cases (1986-2004).

Objective: To determine clinical and radiographic abnormalities in and outcome of horses with fractures of the greater tubercle of the humerus and to develop a radiographic technique for obtaining a cranioproximal-craniodistal oblique projection of the proximal portion of the humerus in standing horses.

Design: Retrospective case series.

Animals: 15 horses.

Musculoskeletal problems associated with lameness and poor performance among horses used for barrel racing: 118 cases (2000-2003).

Objective: To identify types of musculoskeletal problems associated with lameness or poor performance in horses used for barrel racing.

Design: Retrospective case series.

Animals: 118 horses.

Lameness and poor performance in horses used for team roping: 118 cases (2000-2003).

Objective: To determine the types of musculoskeletal problems that result in lameness or poor performance in horses used for team roping and determine whether these problems are different in horses used for heading versus heeling.

Design: Retrospective study.

Animals: 118 horses.

Effects of Carolina rinse solution, dimethyl sulfoxide, and the 21-aminosteroid, U-74389G, on microvascular permeability and morphology of the equine jejunum after low-flow ischemia and reperfusion.

Objective: To evaluate effects of Carolina rinse solution, dimethyl sulfoxide (DMSO), and 21-aminosteroid, U-74389G, on microvascular permeability and morphology of the equine jejunum after low-flow ischemia and reperfusion.

Animals: 20 healthy adult horses.

Procedure: Under anesthesia, full-thickness biopsy specimens of a distal portion of the jejunum were obtained for baseline measurements.

Heel bulb lacerations in horses: 101 cases (1988-1994).

Objective: To determine clinical history, structures involved, treatment, and outcome of lacerations of the heel bulb and proximal phalangeal region (pastern) in horses.

Design: Retrospective study.

Animals: 101 horses.

Gracilis muscle injury as a cause of lameness in two horses.

Injury to the gracilis muscle can cause acute, severe lameness in horses. Two female Quarter Horses that were used for barrel racing sustained gracilis muscle tear injuries. The site of injury was localized by direct infiltration of the area with mepivacaine.

Injection of corticosteroids, hyaluronate, and amikacin into the navicular bursa in horses with signs of navicular area pain unresponsive to other treatments: 25 cases (1999-2002).

Objective: To determine history, clinical and radiographic abnormalities, and outcome in horses with signs of navicular area pain unresponsive to corrective shoeing and systemic nonsteroidal anti-inflammatory drug administration that were treated with an injection of corticosteroids, sodium hyaluronate, and amikacin into the navicular bursa.

Design: Retrospective study.

Animals: 25 horses.

Hoof wall surgery in the horse: approaches to and underlying disorders.

Because of the hoof capsule, surgery of the equine foot is often perceived to be quite difficult. Knowledge of the specific disease entities that require surgical intervention as well as an in-depth understanding of the anatomy of the tissues beneath the hoof capsule is a definite prerequisite to successful surgical treatment. This article details the surgical approaches used to treat septic navicular bursitis, septic pedal osteitis, infection of the collateral cartilages, and keratomas.

Diagnosis, treatment, and farriery for horses with chronic heel pain.

In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event.

Osteomyelitis secondary to trauma involving the proximal end of the radius in horses: five cases (1987-2001).

Objective: To determine clinical, radiographic, and scintigraphic abnormalities in and treatment and outcome of horses with trauma-induced osteomyelitis of the proximal aspect of the radius.

Design: Retrospective study.

Animals: 5 horses.
