Abstract

This report explains typical radiographic features ofScottish Fold osteochondrodysplasia. Three Scottish Foldcats suffering from lameness were referred to theVeterinary Medical Teaching Hospital, Seoul NationalUniversity, Korea. Based on the breed predisposition,history, clinical signs, physical examination, and radiographicfindings, Scottish Fold osteochondrodysplasia was confirmedin three cases. Radiographic changes mainly includedexostosis and secondary arthritis around affected jointlesions, and defective conformation in the phalanges andcaudal vertebrae. The oral chondroprotective agents suchas glucosamine and chondroitin sulfate make the patientsalleviate their pain without adverse effects.

Figure

• 

  Fig. 1 Lateral (A) and dorsopalmar (B) radiographs of the right distal pelvic limbs of the case 1. Extensive periarticular new bone formation around the tarsus (A) and proximal portion of the metatarsus is present. The intertarsal and tarsometatarsal joint spaces and margin (B) appear indistinct compared to normal tarsus (C).

• 

  Fig. 2 Lateral (A) and dorsoplantar (B) radiographs of the right pelvic limb of the case 2. There is mild new bone formation (A) in the plantarolateral aspect of the right pelvic limb. The metatarsal bones (B) are short, thick, splayed, and misshapen compared to normal metatarsal bones (C). The phalanges appear flared and hypoplastic.

• 

  Fig. 3 Tarsal joint radiographs of the case 3. There is exuberant exostosis extending from the proximal calcaneus to the proximal metatarsal bones resulting in bony ankylosis.

• 

  Fig. 4 Dorsopalmar radiographs of the distal hindlimb (A) and forelimb (B) of the case 3. The metatarsal bones (A) are shortened, thickened, and splayed than normal. There is extensive and moderate periosteal reaction of phalanges (B) in the forelimb. The interphalangeal joint spaces are irregular and widening in both A and B.
