FREIBERG DISEASE / SUBCHONDRAL FRACTURE INFRACTION / OSTEOCHONDROSIS
- Extensive oedema in the head of the 2nd metatarsal with slight flattening of the cortical margin is characteristic of what's called Freiberg's Disease in adolescents and Subchondral Fracture in adults.
- Freiberg disease occurs in adolescents with an unfused epiphysis.
- However, the same pathology occurs in adults and is called a subchondral fracture or infraction.
- An Infraction is a non displaced incomplete fracture that results in necrosis of the subchondral bone.
- Frieberg's disease or Infraction most commonly occurs in the 2nd Metatarsal Head.
- Can also occur, but is less common, in the 3rd and 4th metatarsal heads.
- Diffuse bone marrow oedema in the head of the 2nd metatarsal (Pink arrow) with,
- Slight flattening of the 2nd metatarsal head cortical margin (Blue arrow).
