Silastic arthroplasty in rheumatoid MCP-joints: 60 joints followed for 7 years

Rheumatoid arthritis of the temporomandibular joints.

Although temporomandibular-joint involvement by rheumatoid arthritis is well recognized, its incidence is unknown. Russel and Bayles (1941) estimated that the temporomandibular joints became involved in 50 per cent. of patients, Ragan (1949) 4 7 per cent., Markowitz and Gerry (1950) 8 *7 per cent., and Einaudi and Viara (1964) 29 3 per cent in 260 rheumatoid arthritics. These variations may be ...

Why does rheumatoid arthritis involve the joints?

A long-standing question in rheumatology is why inflammatory arthritides such as rheumatoid arthritis involve the joints. Many studies have addressed this question; a recent article by Lee et al.1 provides a new answer that is both obvious and intriguing. Rheumatoid arthritis affects the joints because of the essential role of the synovium in regulating inflammation. The normal synovial membran...

Sagittal laser optical tomography for imaging of rheumatoid finger joints.

We present a novel optical tomographic imaging system that was designed to determine two-dimensional spatial distribution of optical properties in a sagittal plane through finger joints. The system incorporates a single laser diode and a single silicon photodetector into a scanning device that records spatially resolved light intensities as they are transmitted through a finger. These data are ...

Does epithelial-mesenchymal transition happen in rheumatoid joints?

Ankylosis of the finger joints in rheumatoid arthritis.

The ordinary manifestations of rheumatoid arthritis are well known and readily recognized. They are subject to wide variations and, as they deviate farther from the conventional picture, diagnosis becomes difficult, doubtful, or even impossible. The aetiology is unknown and proof of diagnosis is lacking. Even the proposed diagnostic criteria for rheumatoid arthritis (Ropes, Bennett, Cobb, Jacox...
