Extensor Tendon Problems in Rheumatoid Arthritis

Closed Traumatic Rupture of the Extensor Digitorum Communis and Extensor Indicis Proprius at the Musculo-Tendinous Junction

“…Ruptures of extensor tendons are known to occur at the level of the wrist after undisplaced fractures of the distal radius (Anwar et al, 2006;Bonatz et al, 1996;Cheema et al, 2006;Engkvist and Lundborg, 1979;Mannerfelt et al, 1990) and in patients with rheumatoid arthritis (Vaughan-Jackson, 1948;Wilson and DeVito, 1996). In patients who have no predisposing factors, such an injury is very rare and very few cases are described in English literature.…”

Stenosing tenosynovitis of the extensor digitorum tendons of the hand: clinical and sonographic features

“…Morphologic US criteria (thickening of the ER compared by the asymptomatic side, morphologic changes of the EDC), dynamic US criteria (impingement of the EDC against the ER during simultaneous finger and wrist extension), and reproduction of the patient pain during the dynamic impingement. The synovial hypoechoic thickening observed in all our patients and synovial sheath fluid observed in 88.9% of our patients could be confusing with proliferative extensor tenosynovitis which is a common and well-described condition in patients with rheumatoid arthritis [16] that commonly affects the fourth compartment [17,18]. In rheumatic tenosynovitis, the ER remains normal and may even be used for surgical procedure [19].…”

Tendon transfer or tendon graft for ruptured finger extensor tendons in rheumatoid hands

“…Tendon transfer is used more commonly. Good results have been reported but are less reliable for multiple tendon ruptures (Leslie, 1989;Moore et al, 1987;Shannon and Barton, 1976;Williamson and Feldon, 1995;Wilson and DeVito, 1996). Results from tendon grafting are more mixed.…”
