Double Dislocation of the Finger: A Rare Occurrence

Simultaneous Dorsal Dislocation of the Interphalangeal Joints in Ring Finger With Proximal Interphalangeal Joint Dislocation of the Middle Finger: Case Report and Review of the Literature

“…This was thought to be because the dislocating force was thought to dissipate in one finger. 7 The little finger has almost always been the affected one especially in the young fit athlete and this was thought to be due to the fact that surrounding fingers does not protect this finger. There have been two reported cases 2,8 where the trauma has been more violent and this has involved the middle finger.…”

“…7 Surgery is required only when there is co-existent volar plate injuries or tear of the collateral ligaments.…”

Double Dislocation of Distal Interphalangeal (DIP) and Proximal Interphalangeal (PIP) Joints of the Little Finger

“…The little finger of the dominant hand is most frequently involved, followed by the ring finger [3,4]. The possible explanation is the lack of protection to the little finger, by the adjacent surrounding fingers, or due to weakness of supporting ligaments [7]. Another possible reason is that the bony anatomy of the finger itself leads to greater laxity on extension, with the shallow articular surface of the proximal phalanx resting on the spherical head of the distal phalanx [8].…”

Unusual Double Dislocation of Both Joints in a Same Finger: A Case Report

“…Little finger followed by ring finger of dominant hand is most commonly involved. This is due to its weak ligaments and unsupported environment from surrounding ( 8 - 10 ). It may be associated with volar plate fracture of middle phalanx in distal interphalangeal dislocation and buttonholing through extensor aponeurosis by condyle of proximal phalanx in proximal interphalangeal joint dislocation, which may cause difficulty in reduction and entails open reduction.…”
