case_images: 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

case_images: 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.
