[Synovitic and enthesitic changes in the hand during reflex dystrophy].

Synovial reactions do not only affect articular but also tenosynovial compartments as proven by low kV radiography in 3 views. Erosions develop in both compartments and also enthesitically at the insertions of fibrous structures. There are also localized osseous changes, which resemble localized areas of hyperparathyroidism. In cases with unilateral trauma of a lesser degree scintigraphic examination of the soft tissues and bones of the contralateral side may confirm the results. The response of the soft tissues and bones is more severe distally.
