Diagnosis

Bunk bed fracture of 1st metatarsal.

Findings

XR – Nondisplaced medially impacted fracture of the base of the first metatarsal.

Discussion

Bunk bed fractures are a common injury in children but often overlooked. These fractures are produced as a result of landing on a plantar flexed foot, usually from a fall or a jump.

Plantar flexion leads to wedging of the first metatarsal between the medial cuneiform and second metatarsal. This is accentuated by the normal ventral concavity of the proximal first metatarsal and the horizontal obliquity of the medial cuneiform. Avulsion forces by the tibialis anterior and peroneus longus tendons may also contribute to bunk bed fractures.

The bunk bed fracture is associated with ligamentous injury at the tarsometarsal junction and is considered a pediatric variant of the Lisfranc injury.
