case_images: Anteroposterior and lateral radiographs (a, b) of the index finger showing dorsal dislocation of both the proximal and distal interphalangeal joints, without any bony avulsion fracture. Postreduction anteroposterior and lateral radiographs (c, d) confirm that all joints are well reduced.

case_images: Initial plain radiographs demonstrated a dorsal dislocation of PIP and DIP joints of his little finger in a step-ladder deformity (Figure 1). Following reduction, both joints were stable and confirmed on plain radiographs with no apparent any bony avulsion fragment or fracture (Figure 1).
