ORTHOPEDICS

apex of the posterior facet and anterior process of the calcaneus). A Bohler’s
angle of 20°–40° is normal. CT scan may be needed to determine if injury is
extensive enough to require surgery.

TREATMENT

Posterior splint, non-weight-bearing; orthopedic consult

COMPLICATIONS

■ Comminuted fractures have high rates of compartment syndrome.
■ Associated lumbar vertebrae compression fractures(10–15%)
■ Chronic pain and disability

TALUSFRACTURE

The talar neck is the most common location.

TREATMENT

■ Minor avulsion fractures can be treated with a posterior splint and crutches.
■ Major fractures of the neck and body require orthopedic consultation as
these fractures often require ORIF.

COMPLICATIONS

High rates of avascular necrosisand chronic arthritis

LISFRANC(TARSOMETATARSAL) FRACTURE

Lisfranc joint is a six-bone tarsometatarsal complex made up of the proximal
most medial (1–3) metatarsals and their adjoining tarsal bones.
