Rheumatoid Arthritis: Extensor Tendon Rupture

The fourth and fifth fingers cannot be extended because the extensor tendons to these digits have ruptured. Surgical exploration confirmed the rupture. Contributing factors included tenosynovitis of the extensor tendons and dorsal subluxation of the ulna

Rheumatoid Arthritis: Fusiform Swelling, Hand

Soft-tissue swelling is an early finding in rheumatoid arthritis and usually appears as typical fusiform or spindle-shaped enlargement of the proximal interphalangeal joints. The second and third fingers of this patient are most involved. These proximal i

Rheumatoid Arthritis: Deformities, Hands

A woman with long standing rheumatoid arthritis has soft tissue swelling and subluxation of the metacarpophalangeal joints. The right thumb shows hyperextension of the interphalangeal joint (a Z deformity). Both ring fingers have Boutonniere deformities w

Rheumatoid Arthritis: Subluxation and Muscle Atrophy, Hands

Synovitis and volar subluxations of the metacarpophalangeal joints are shown in these hands. Early ""swan-neck"" deformities, interosseous muscle atrophy, and wrist swelling are present.

Rheumatoid Arthritis: Chronic Changes, Hands

Ulnar deviation, metacarpophalangeal joint subluxation, and intrinsic muscle atrophy are present in the hands of a patient with longstanding rheumatoid arthritis. Rheumatoid nodules are seen over the proximal interphalangeal joints of the patient's right

Rheumatoid Arthritis: Telescoping Digits, Hands

This patient with longstanding rheumatoid arthritis demonstrates the ""opera-glass hand"" or main en lorgnette deformity, characterized by severe joint destruction, loss of bone substance, and shortening of the digits. These changes have resulted in teles

Rheumatoid Arthritis: Carpal Tunnel Syndrome, Hand

Compression of the median nerve in the carpal tunnel is not an unusual finding in patients with rheumatoid arthritis, although it may also occur in other disorders. In this case, thenar atrophy has resulted from damage to the median nerve caused by pressu

Rheumatoid Arthritis: Hand, “Opera Glass Hand”

Dorsal view of the hand of someone with long-standing erosive rheumatoid arthritis shows the consequence of extensive bony resorption. Loss of skeletal elements resulted in marked foreshortening of the digits, culminating in “opera glass” deformity of th

Rheumatoid Arthritis: Popliteal Cyst

This patient with longstanding rheumatoid arthritis involving multiple joints had popliteal pain bilaterally and developed pronounced swelling with pain along the posteromedial portion of the right leg. The swelling results from a ruptured popliteal cyst

Rheumatoid Arthritis: Crescent Sign, Ruptured Popliteal Cyst

A middle-aged man with classic rheumatoid arthritis developed a right knee effusion after dancing. Two days later the right calf became tender and swollen. Four days thereafter a distinct crescentic discoloration appeared below both malleoli. This crescen

Rheumatoid Arthritis: Crescent Sign, Ruptured Popliteal Cyst

A 48-year-old female with rheumatoid arthritis developed a ruptured popliteal cyst which resulted in swelling and ecchymosis of the lower extremity. Pooling of blood at the ankle and foot produces the classic “crescent sign.”

Rheumatoid Arthritis: Protruding Metatarsal Heads

A common feature in rheumatoid arthritis in the feet is prominence of the metatarsal heads due to metatarsophalangeal subluxation. Note also superimposed callosities and hammertoes.

Rheumatoid Arthritis: Foot Deformities

The most common foot deformities in rheumatoid arthritis are hallux valgus and hammertoes. The ""cock-up"" toe deformities in this patient are associated with subluxation of the metatarsophalangeal joints. Painful corns and bunions over these deformities
