Summary

Medical records of 22 horses with humeral fractures were reviewed. The horses were from 2 to 144 months old (mean, 25.8 ± 37.3 months). Ten horses were treated with stall confinement, 3 were treated surgically, and 9 were euthanatized at the time of diagnosis. Seven of 10 horses treated nonsurgically (stall confinement) were able to be ridden 5 to 12 months after the diagnosis was made (mean, 7.5 ± 2.6 months). One horse treated nonsurgically was euthanatized 6 months after diagnosis because of laminitis in the contralateral limb. Two horses treated nonsurgically were lost to follow-up evaluation.

Two of the 3 horses treated surgically had fractures repaired with Rush pins. The fractured humerus of the third horse was repaired with lag screws. Of the 3 surgically treated horses, 1 was pasture sound 10 months after surgery, but developed varus deviation in the contralateral carpus 6 weeks after repair; 1 horse was euthanatized 2 weeks after surgery because of failure of the implant; and the other horse was sound for riding 10 months after surgery.

On the basis of these findings, young horses with humeral fractures that are treated nonsurgically can become sound for riding.

Summary:

Over a 3-year period, proventriculotomy was performed on 18 ostriches to relieve impaction of the proventriculus. Diagnosis was confirmed by abdominal palpation, abdominal radiography, and in some cases, exploratory proventriculotomy. In addition to proventriculotomy, an esophagotomy was performed in 5 birds that were debilitated to allow forcefeeding during the postoperative period. The median age of ostriches treated surgically for proventricular impaction was 7.5 months (range, 3 months to 18 years).

Impactions consisted of sand, rocks, or gravel in combination with grass, leaves, wood, or other fibrous materials. In 7 birds, small pieces of wire or nails were also removed from the proventriculus. In 1 bird, a large metal punch was removed via the proventriculotomy.

Six ostriches died at the hospital in the immediate postoperative period. Four of these died within 24 hours of surgery. All 4 birds were emaciated and in a severely weakened condition at admission, and they continued to deteriorate after surgery. One bird died 8 days after surgery as a result of complications associated with a septic joint unrelated to the proventriculotomy procedure. Another bird was euthanatized 6 days after surgery because its condition failed to improve and the owners did not want to pursue further treatment because of expense. Follow-up information was obtained for 12 surviving ostriches 1 week to 29 months (median, 5.5 months) after they were discharged from the hospital. Four of the 12 birds died within 30 days of discharge from the hospital. The remaining 8 birds (44%) were alive at follow-up evaluation (median, 10.5 months after surgery; range, 5 to 29 months). In the birds that survived long-term, complications associated with the proventriculotomy or esophagotomy were not observed.
