Pediatric Mallet Deformity

- Discussion:
    - younger children will tend to have SH II fractures of the epiphysis of the distal phalanx;
    - older children tend to have SH III fractures.
    - the main epiphyseal fragment is held in place by the extensor tendon, while the distal fragment is flexed by the FDP;

- Treatment:
    - displaced SH III fracture may require ORIF w/ pinning if a stable reduction cannot be obtained
