Metatarsal fracture (4th)

Linear hypodensity

4th metatarsal proximal third non-displaced fracture.

Callus

The fracture line is difficult to visualize and partially filled by a callus. This is a stress fracture of at least 10-14 days old.

Hallux valgus

Bone deformity

Important hallux valgus with a metatarsophanlangeal angle increased to 40° (normal at 15°).

Metatarsus varus

Bone deformity

The hallux valgus is associated to a metatarsus varus with an intermetatarsal angle increased to 15° (normal at 10°). This angle is underrated because of the abnormal forefoot structure (metatarsus adductus).

Interphalangeal angle

Normal interphalangeal angle of about 5° (this angle is considered normal if smaller than 8°).

Sesamoids

The sesamoids are displaced medially.
