Acute compartment syndrome of the foot — a surgical emergency resulting from increased pressure within the closed fascial compartments of the foot that compromises perfusion to intrinsic muscles and nerves — occurs most commonly following high-energy foot trauma (crush injuries, Lisfranc fractures, calcaneal fractures, multiple metatarsal fractures) or prolonged vascular ischemia followed by reperfusion. Missed or delayed foot compartment syndrome produces irreversible intrinsic muscle necrosis resulting in the cavus foot deformity with claw toes and intrinsic minus foot — a devastating permanent disability. The diagnosis requires a high index of clinical suspicion and does not require compartment pressure measurements to proceed to fasciotomy when clinical signs are compelling.

Anatomy and Diagnosis

Foot compartment anatomy: the foot contains 9 compartments — medial (abductor hallucis, flexor hallucis brevis), central superficial and deep (lumbricals, flexor digitorum brevis, quadratus plantae), lateral (abductor digiti minimi, flexor digiti minimi brevis), interosseous compartments (4 — dorsal interosseous muscles), and calcaneal (quadratus plantae origin). Clinical diagnosis: the 6 P’s of compartment syndrome — pain (disproportionate to the injury, characteristically burning or burning-aching quality), pressure (tense, swollen foot), paresthesias (tingling in the distribution of compressed nerves — dorsal and plantar), paresis (weakness of intrinsic muscles — inability to flex/extend toes against resistance), pallor (late sign — loss of capillary refill), pulselessness (very late sign — do not wait for this). Compartment pressure measurement: normal < 10 mmHg; fasciotomy indicated when measured pressure within 30 mmHg of diastolic blood pressure (delta-P < 30 mmHg) — this is the delta-P criterion that triggers fasciotomy in equivocal cases.

Fasciotomy Technique

Dorsal approach: two longitudinal dorsal incisions over the 2nd and 4th metatarsals release the four interosseous compartments; medial incision from the navicular to the first MTP joint releases the medial and central compartments. Medial approach: single medial longitudinal incision from the posterior calcaneus to the first metatarsal head releases the medial, central, and calcaneal compartments — recommended as the primary approach by many authors. Wound management: wounds are left open and covered with moist dressings; delayed primary closure at 48–72 hours when swelling subsides; split-thickness skin graft for wounds that cannot be primarily closed. Late complications of missed diagnosis: intrinsic muscle fibrosis producing clawing of all toes (intrinsic minus foot), cavus deformity, and chronic plantar pain from fibrosis — requiring tendon lengthening and plantar fascia release for functional improvement.

Frequently Asked Questions

When should I see a podiatrist?

See a podiatrist for any foot or ankle pain that persists more than 2 weeks, doesn’t improve with rest, limits your daily activities, or is accompanied by swelling, numbness, or skin changes. People with diabetes or circulation problems should see a podiatrist regularly even without symptoms.

What does a podiatrist treat?

Podiatrists diagnose and treat all conditions of the foot, ankle, and lower leg including plantar fasciitis, bunions, hammertoes, toenail problems, heel pain, nerve pain, diabetic foot care, sports injuries, fractures, and foot deformities — both surgically and non-surgically.

What can I expect at my first podiatry visit?

Your first visit includes a full medical history, physical examination of your feet and gait, and in-office diagnostic imaging if needed (X-rays, ultrasound). We’ll discuss your diagnosis and create a personalized treatment plan. Most visits take 30–45 minutes.
