A condition usually occurring in middle-aged people in which the victim ﬁnds on wakening in the morning that he or she cannot straighten the ring or middle ﬁnger spontaneously, but only by a special eﬀort, when it suddenly straightens with a painful click. Hence the name. In due course the ﬁnger remains bent at all times unless a special eﬀort is made to straighten it with the other hand. The condition is due to a swelling developing in one of the tendons of the aﬀected ﬁnger. If the tendon sheath is slit open surgically, the condition is relieved. Many cases recover spontaneously if the patient is prepared to wait.
