Design-Retrospective study. Animals-Horses (n ¼ 41) with navicular syndrome (NS). Methods-Medical records (1998-2002) for horses that had NS and failed to respond to conservative management that had unilateral or bilateral forelimb, biaxial PDN were reviewed. Outcome for up to 6 years was obtained by telephone questionnaire or lameness examination. Survival analysis was used to assess time to recurrence of lameness. Results-One year after PDN, 36 horses (88%) were free of lameness. Mean survival with no lameness after surgery was estimated at 4.14 AE 0.33 years (median, 5 years). Conclusions-PT-PDN technique resulted in soundness for 88% of horses for at least 1 year. PT-PDN was easily and quickly performed without specialized equipment, and had a low incidence of complications. Clinical Relevance-The PT technique is an effective and viable alternative surgical method for PDN.

Clinical Findings—Ultrasonography of the right metacarpal area revealed hypoechoic areas in the right digital sheath and metacarpophalangeal joint consistent with synovial effusion. Radiography of the right metacarpophalangeal joint revealed lysis of the axial border of the proximal sesamoid bones. Aspergillus fumigatus was detected on fungal culture of synovial fluid. Treatment and Outcome—Regional limb perfusion (150 mg of amikacin in 60 mL of saline [0.9% NaCl] solution perfused for 30 minutes) was performed 2 and 4 days after admission. Itraconazole (5 mg/kg [2.27 mg/lb], PO, q 24 h) was administered for approximately 9 weeks. Joint lavage with amikacin (500 mg) in 1 L of saline solution was performed 4 times. Three months after discharge, the owner reported that the horse was mildly lame during trotting but was moving freely and comfortably during all gaits and ...

Research paper thumbnail of Fractures of the palmar aspect of the carpal bones in horses: 10 cases (1984–2000)

Journal of the American Veterinary Medical Association, 2001

Design—Retrospective study. Animals—10 horses. Procedure—Medical records were reviewed to obtain information on history, signalment, clinical and radiographic findings, treatment, and outcome. Follow-up information was gathered from owners and referring veterinarians. Results—7 horses became lame after recovery from general anesthesia for treatment of an unrelated problem. The remaining 3 horses developed a forelimb lameness after falling (1 horse) or being turned out in a pasture (2 horses). Fractures involved the palmar surface of the radial carpal bone in all 10 horses; in addition, the ulnar carpal bone was affected in 2 horses, the intermediate carpal bone in 2 horses, and the distal aspect of the radius in 4 horses. None of the 4 horses tr...

Fractures of the distal aspect of the radius and of the radial, intermediate, and third carpal bones are the most common and are thought to be related to chronic cyclic loading and superimposed acute compressive forces. 1-4 Progressive subchondral bone sclerosis induced by repetitive trauma predisposes to fracture of these bones. The inflammatory response that follows results in synovitis and capsulitis and, if left untreated, osteoarthritis
