Can an Anomaly in Dog's Spine Cause Hip Dysplasia? New Study Unveils Surprising Link
A groundbreaking study has revealed a surprising connection between a common spine anomaly in dogs, known as asymmetric lumbosacral transitional vertebra (LTV), and hip dysplasia (CHD). Researchers analyzed ventrodorsal radiographs of 13,950 dogs across 14 breeds, finding that 18.5% of them had an LTV, with 21.4% of those being asymmetrical.
The study found that dogs with an asymmetric LTV often had a shorter sacroiliac joint on the affected side, causing a shift in the pelvis. This unevenness led to a reduced distance to the hip joint and a significant rotation of the pelvis. The result? A higher likelihood of asymmetrical hip dysplasia, which could have serious long-term effects on a dog’s mobility and health.
Key findings include that the asymmetrical LTV segment caused a compensatory vertical counter-rotation of the pelvis, potentially straightening the lower back but also promoting hip dysplasia. The study highlights the importance of identifying LTV early in dogs, particularly those predisposed to hip dysplasia, such as German Shepherds, to help manage and prevent further complications.
This research underscores how a seemingly minor spinal anomaly may significantly influence a dog's pelvic morphology, ultimately contributing to orthopedic issues like hip dysplasia. Pet owners and veterinarians alike should be aware of this potential link when diagnosing and treating hip problems in dogs.
