The July 1985 VA examination also fails to support a finding of continuity of symptomatology or medical nexus. At that time, the Veteran related an in-service history of back pain but did not report his post-service work-related injuries in 1979. While the examiner diagnosed periodic low back pain with no limitation of motion, there was no opinion rendered as to a causal relationship between the Veteran's complaints and military service. The Board also notes that a June 1985 X-ray report showed a congenital transitional vertebra with changes - 15 - on the left related to the anomaly. Therefore, to the extent the Veteran claims osteoarthritis of the lumbar spine, it appears to be related to a congenital deformity which cannot be service-connected. Under the relevant regulations, congenital or developmental defects are not diseases or injuries within the meaning of applicable legislation. 38 C.F.R. § 3.303(c).
