Closed irreducible dislocation of the interphalangeal joint of the thumb: report of two cases.

Abstract

Two cases of closed dislocation of the interphalangeal joint of the thumb are presented. It was impossible to achieve manual reduction in either patient. This rare injury required open reduction with anatomical repositioning of the volar plate in both patients. We fixed the IP joint with a steel wire after reduction in both cases because of slight joint instability. At the latest follow-up, both patients do not have any problems with in daily life.
