Surgical repair of an oesophageal stricture and prestenotic dilatation in a horse.

Prestenotic oesophageal dilatation and stricture were diagnosed in a horse with a history of trauma in the cervical area and recurrent oesophageal obstruction. The diagnosis was established on the basis of the clinical examination, endoscopy, and positive contrast oesophagography. Conservative treatment was unsuccessful and surgical intervention was necessary. Oesophageal myectomy combined with myoplasty was performed, simultaneously relieving the dilatation and the stricture. No abnormalities were detected 8 weeks after surgery. The horse was on a normal diet and oesophageal obstruction did recur in the subsequent 14 months.

Impingement of the dorsal spinous processes in two hundred and fifteen horses: case selection, surgical technique and results.

The surgical treatment of impingement of dorsal spinous processes (DSPs) at 2 equine veterinary hospitals following a similar diagnostic and surgical protocol is described with special reference to the diagnosis and case selection. The diagnosis was made from clinical examination and results of radiography and diagnostic analgesia of the affected sites. Scintigraphy was also used as an aid to diagnosis at one hospital. Surgical treatment was generally recommended when conservative treatment, which included 3-9 months rest, intralesional corticosteroids and physiotherapy, had failed. The DSPs were approached through a midline incision in the skin and supraspinous ligament. They were resected using an oscillating saw. Postoperatively, horses were returned to lungeing work after 2 weeks and riding commenced at 3 months, in most cases, and by 6 months in all successful cases. From one to 6 DSPs between thoracic vertebra (T) 11 and lumbar vertebra (L) 3 were resected in individual horses. T15, 16 and 17 were the spines most commonly treated. Long-term follow-up information was obtained in 209 horses. Seventy-two percent of these horses returned to full work and a further 9% improved sufficiently to be used for some athletic work.

Outcome and racing performance after internal fixation of third and central tarsal bone slab fractures in horses. A review of 20 cases.

Twenty horses with central and third tarsal bone slab fractures, were treated internal fixation. Eighteen of the 20 cases were Standardbred trotters, one was a Thoroughbred racehorse and one a Swedish Warmblood. The central tarsal bone (CT) was involved in 12 cases and the third tarsal bone (T3) in 8 cases. The fractures were treated by lag screw fixation with one (18 cases) or two (2 cases) 3.5 or 4.5 mm cortical screws. Horses were confined to stall rest for one month and then put on a gradually increasing exercise programme. Convalescence time was 3-8 months until the fracture had healed and training could be resumed. Fifteen of the horses regained athletic soundness. Thirteen of the horses (72%) raced after surgery (12 Standardbreds and 1 Thoroughbred). Nine (69%) of these 13 horses won races after surgery.
