Clinical Relevance

Clinical Notes

Foot compartment syndrome follows crush injuries, calcaneal fractures and Lisfranc injuries, and the medial compartment is released through a medial incision that can also reach the calcaneal compartment. The medial plantar nerve and tibial vessels pass close to abductor hallucis, which can compress them.

Pathology

Common Injuries & Conditions

Foot Compartment Syndrome

Raised pressure in the compartments of the foot, usually after crush or calcaneal fracture, causing severe pain and, if untreated, clawed toes from muscle scarring.
