Nine cases of locking of the metacarpo-phalangeal joint are described. The previously asymptomatic middle finger joint in an elderly person was most likely to be affected. Radiology of the joint has shown degenerative changes in all cases. In two patients, spontaneous unlocking of the joint occurred and in a further six operative release was undertaken. The important anatomical features of the condition are discussed in relation to the mechanism of locking and the surgical treatment.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
