Trigger thumb of de Quervain's disease.
Triggering of the thumb due to de Quervain's Disease has not been reported in an adult, and only one case in a child has been documented in the literature. Two cases of trigger thumb that were due to stenosing tenosynovitis in which the extensor pollicis brevis tendon triggered in a separate fibro-osseous tunnel within the first dorsal compartment are cited.
