Simultaneous double dislocation of the interphalangeal joint of the same finger: a report of two cases.

Seki Y - Pan Afr Med J (2014)

Bottom Line: Two patients were treated conservatively.The mechanism of the injury is believed to be hyperextension of both the DIP and PIP joints.Closed reduction is the treatment of choice and early active range of motion to prevent joint contracture should be recommended.

ABSTRACT
Simultaneous dislocation of both the proximal and distal interphalangeal (PIP and DIP) joints in a finger is uncommon. Two patients were treated conservatively. Both two patients fell from a step-ladder and X-rays revealed dorsal dislocations of both PIP and DIP joints of their right little fingers. Manual reduction was easily achieved with gentle longitudinal traction. The mechanism of the injury is believed to be hyperextension of both the DIP and PIP joints. Closed reduction is the treatment of choice and early active range of motion to prevent joint contracture should be recommended.

Figure 0001: Case 1 (A) X-rays of the little finger showing dorsal dislocation of both the proximal and distal interphalangeal joints (step-ladder deformity); (B) Post-reduction X-rays confirming that both joints are well reduced, but the PIP joint had a volar rim fracture

Mentions: Case 1: a 64-year-old man fell from a step-ladder, injuring the right little finger. On physical examination, the finger was found to be deformed, and an X-ray demonstrated a dorsal dislocation of both the PIP and DIP joints (Figure 1A). Manual reduction was easily achieved with gentle longitudinal traction; however, the X-ray after reduction (Figure 1B) revealed an avulsion fracture of the volar proximal rim of the middle phalanx. A dorsal splint was applied for three weeks and then rehabilitation was started. At the final review there was no joint instability, whereas the PIP flexion was 90 degrees and the extension deficit was 10. The range of motion had a slight limitation; however, the patient had no complaint of pain or functional deficit.
