Avascular necrosis of the metatarsal head is known as Freiberg’s infraction and most commonly occurs in the second metatarsal. It is more prevalent in women and the condition most often manifests in the adolescent years between the ages of 11 and 17.1What is Freiberg disease?
Freiberg disease, also known as Freiberg infraction, is osteochondrosis of metatarsal heads. It typically affects the 2nd metatarsal head, although the 3rd and 4th may also be affected.Does Freiberg's disease affect the second toe?
It is not uncommon for Freiberg’s disease to be associated with a long second toe, as this can increase the repetitive force that the second metatarsal head is subject to. X-rays will usually allow Freiberg’s disease to be diagnosed. They will often show a change in the shape of the affected metatarsal head (Figure 1).What are the most common causes of Freiberg injuries?
When someone is told they have a Freiberg infraction, this often arises due to multiple reasons. One of the most common causes is a traumatic injury. Whether someone strikes their foot during an auto accident or sustains damage to the bones of the feet in a slip and fall event, a blow to the metatarsals can compromise their integrity.
