Atlanto-axial malarticulation in Angora goats
Australian Veterinary Journal
|March 1, 1982
Summary
Two Angora goats experienced hind limb weakness and ataxia due to atlanto-axial joint instability. This vertebral anomaly led to spinal cord compression and neurological deficits, impacting their mobility.
Area of Science:
- Veterinary Neurology
- Comparative Pathology
- Goat Medicine
Background:
- Atlanto-axial joint instability can cause neurological signs in animals.
- Angora goats are susceptible to various musculoskeletal and neurological conditions.
- Understanding spinal cord pathologies is crucial for animal health.
Observation:
- Two male Angora goats presented with progressive ataxia and hind limb weakness.
- Clinical signs included exercise intolerance, stumbling, and falling.
- Post-mortem examination was performed on both animals.
Findings:
- Spinal cord lesions at the atlanto-axial joint included gliosis and Wallerian degeneration.
- Myelomalacia (spinal cord tissue death) was observed in one goat.
- Vertebral anomalies, including convex atlas articular surfaces and a compressed axis odontoid process, were noted in the other goat.
Implications:
- Vertebral anomalies at the atlanto-axial joint can cause excessive joint mobility.
- This instability can lead to compressive myelopathy and neurological dysfunction in goats.
- Identifying these vertebral abnormalities is key for diagnosing and managing neurological conditions in Angora goats.
