Answer

Diagnosis

  • Freiberg infraction, osteonecrosis of the second metatarsal head
  • Most common in adolescent females
  • Third metatarsal head is the next most frequent site

Smillie classification

IFissure fracture
IICentral collapse
IIIFurther collapse with an intact plantar hinge
IVLoose bodies
VFlattened head with arthritis

Aetiology

  • Repetitive loading of a long, stiff second metatarsal
  • High heels and dance increase forefoot load

Management

  • Stiff soled shoe, metatarsal bar or walking boot
  • Joint debridement and loose body removal
  • Dorsal closing wedge osteotomy to rotate healthy plantar cartilage into the joint
  • Interposition arthroplasty or partial head excision for late stages
  • Most early stages settle with offloading
