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