simultaneous dorsal dislocation of the proximal and distal interphalangeal joints in the middle finger: a case report

Introduction: dorsal dislocation of a proximal or distal interphalangeal joint is a common clinical problem. however, simultaneous dislocation of both joints in the same digit is rare. case presentation: a 32-year-old male injured his left hand third finger while biking. examination revealed a stepladder deformity. neurovascular examination was normal. radiographs revealed dorsal dislocation of both the proximal and distal interphalangeal joints. the finger was reduced easily by longitudinal manual traction under the digital block. the finger was splinted in the intrinsic plus position for 3 weeks accompanied with active range of motion. after 6 months, the patient returned to normal sporting activity without limitation of motion. conclusions: in case of simultaneous dorsal dislocation of a proximal and distal interphalangeal joint, closed reduction is the treatment of choice and it could result in good and normal range of motion.
