Trigger wrist due to idiopathic synovial hypertrophy

The phenomenon of "trigger wrist" has been reported several times since 1961, when it was first described (Eifel, 1961). Most of these cases related to patients suffering from "triggering" at the wrist associated with carpal tunnel compression. Below is a hitherto undescribed case of trigger wrist occurring in a fit girl, without carpal tunnel syndrome, due to idiopathic synovial hypertrophy.
