Tibiotarsal arthrodesis in a Moufflon sheep
Journal of the American Veterinary Medical Association
|November 1, 1978
Summary
A Moufflon sheep experienced severe leg joint injury and underwent surgical repair. Despite successful arthrodesis, the sheep later died from a fractured ulna after rejoining its flock.
Area of Science:
- Veterinary Orthopedics
- Sheep Medicine
- Animal Surgery
Background:
- Osteoarthritis in mature Moufflon sheep can predispose joints to severe injury.
- Surgical intervention, including arthrodesis, is a potential treatment for complex joint fractures in livestock.
Observation:
- A mature Moufflon sheep with pre-existing tibiotarsal osteoarthritis suffered fracture and luxation during restraint.
- The sheep underwent internal pin fixation and external casting for arthrodesis.
Findings:
- Post-operative recovery was initially successful, with the sheep returning to its flock after 3 months.
- The sheep sustained further trauma due to flock social dynamics, leading to a fractured ulna and subsequent death from exposure 7 months after surgery.
Implications:
- This case highlights the challenges of managing severe orthopedic injuries in free-roaming livestock.
- Reintegration into social groups can pose risks for animals with compromised physical integrity.
- The long-term prognosis for arthrodesis in large animals must consider environmental and social factors.
