Key structures within the lower leg compartments and alterations seen with injury ^{2, 13}

Compartment	Muscle	Artery/Vein	Nerve	Alterations with injury
Anterior	Extensor muscles: • Tibialis anterior • Extensor hallicus longus (EHL) • Extensor digitorum longus (EDL)	Anterior tibial	Deep peroneal	↓/(-) Sensation of great toe web space ↓(-) Foot dorsiflexion and inversion ↓(-) Lateral four toes dorsiflexion ↓(-) Great toe dorsiflexion (EHL test) (-) Dorsalis pedis pulse
Lateral	• Fibularis longus • Fibularis brevis	Peroneal	Superficial peroneal	↓(-) Sensation anterolateral shin/dorsum foot ↓(-) Foot plantar flexion ↓(-) Foot eversion
Superficial posterior	Superficial flexor: • Soleus • Gastrocnemius • Plantaris	Posterior tibial	Tibial	↓(-) Foot plantar flexion
Deep posterior	Deep flexor: • Tibialis posterior • Fibularis hallicus longus (FHL) • Fibularis digitorum longus (FDL)	Posterior tibial and Peroneal	Tibial	↓(-) Sensation plantar aspect of the foot ↓(-) Great toe plantar flexion ↓(-) Lateral four toes plantar flexion ↓(-) Foot inversion (-) Posterior tibial pulse

Alterations with injury: ↓ depicts decrease sensation or motor function in early ACS or (-) depicts absence of sensation, motor function or pulses in late ACS.
