Distal stenosing tenosynovitis

Abstract

Three patients are described with distal stenosing tenosynovitis involving the flexor digitorum profundus and the A3 pulley. One patient had isolated distal stenosing tenosynovitis and two patients had combined distal and proximal stenosing tenosynovitis of the flexor digitorum superficialis and the A1 pulley. All three patients with four digits involved had improvement of their symptoms after release of the A3 pulley. When involved, the A1 pulley was released at the same time. Patients with proximal stenosing tenosynovitis may have an associated distal stenosing tenosynovitis that if overlooked may cause persistence of symptoms after surgical treatment.
