Scottish fold osteochondrodysplasia (SFOCD) is a genetic disorder (incomplete dominance of dominant traits) characterized by skeletal deformations. In homozygous individuals, joint lesions progress until the cat is unable to walk. On X-rays, the metaphyses of the metatarsals and metacarpals are significantly distorted. This results in reduced length and abnormal shape of the bones and distal limbs. Clinical and radiographic evidence showed short caudal vertebrae, widened endplates, and prominent exostoses on the tarsals and metatarsals.

The picture shows a Scottish Fold cat. There was no evidence of gait change, lameness, or pain. There is smooth bone remodeling around the joint, the joint space (the two metatarsal joints) narrows, and osteophytes form. The soft tissue around the joint is swollen, which may manifest as synovial hyperplasia or non-invasive synovitis. There is mild periarticular smooth bone remodeling at the caudal end of the right elbow joint, and there are two pinpoint mineralizations from the caudal end to the supratrochlear foramen. Visible on the medial side.

This mineralization may be a feline synovial osteochondroma or signs of fractured osteophytes. X-ray showed multifocal bilateral degenerative joint disease and early ankylosis.
