Plain-English summary
A study looked at the bones of 1,018 Labrador retrievers that were at least one year old to find issues like elbow and hip dysplasia (abnormal development of these joints) and other bone problems. The researchers found that elbow dysplasia was the most common issue, affecting about 18% of the dogs, and it was more common in males. Hip dysplasia was the second most common, affecting about 13% of the dogs, and it was seen equally in both males and females. Some dogs had both elbow and hip dysplasia, and transitional vertebrae (abnormal vertebrae in the lower back) were more often found in females. The study suggested that some of these bone issues might be inherited.
Abstract
A radiographic study of the humeral head, elbow joint, hip joint, stifle joint, tarsal joint, and lumbosacral (LS) junction was performed in 1,018 Labrador retrievers in search for humeral head, femoral condyle, and tarsal osteochondroses; elbow and hip dysplasias; and transitional LS vertebrae. The ages of all dogs reported were one year or older. Elbow dysplasia was detected as the most common lesion (17.8%), with a higher prevalence in the male dog. Hip dysplasia was the second most common lesion (12.6%) and was found equally in the male and female. Elbows and hips were often affected in the same dog (4.2%). Transitional vertebral segments were found more frequently in the female (4.2%) than in the male (1.0%), and the condition was thought to be inherited.
