1 · SNAPSHOT
Who: Runners and military populations. Often bilateral.
What: Exertional pressure symptoms in a leg compartment — anterior and deep posterior most commonly.
How it behaves: Reproducible tightness, ache or numbness that builds with exercise at a fairly consistent time, distance or intensity, and relieves within minutes of stopping. Normal at rest.
The one thing to take from this page:
The onset-and-relief timing is the diagnosis. A pressure number without that story is not a diagnosis, and a pressure number that contradicts the story should lose.
The timing test
| Fits CECS | Ask a different question |
|---|---|
| Builds at a predictable point each session | Random, unpredictable onset |
| Settles within minutes of stopping | Doesn't settle — persists at rest |
| Normal exam at rest | Tender at rest → MTSS |
| Diffuse compartment tightness | Focal point tenderness → stress fracture |
| Reproducible with the same run | Pain out of proportion, progressive neurology → acute compartment syndrome |
⚠️ No Australian guideline exists. The strongest document is an international Delphi consensus statement — expert agreement, not trial evidence. Nothing on this page rests on a randomised comparison.
2 · SE — THE SUBJECTIVE PATTERN (the 70%)
Five stages, in your course's order. The exam can be completely normal, so the history is not the 70% here — it is closer to the 90%.
MAIN PROBLEM
"About 3km in, my shins get so tight I have to stop."
"It goes away almost as soon as I walk."
"My foot slaps and I get pins and needles when I run."
Get the number out of them. Time, distance, pace or intensity — the reproducibility is the finding.
BODY CHART
- Compartment, not a line. Diffuse through the anterior or deep posterior compartment.
- A line along the posteromedial tibial border is MTSS.
- A point you can cover with a fingertip is a stress fracture.
- Mark numbness, foot slap and weakness separately.
BEHAVIOUR
| Fits CECS | Points elsewhere | |
|---|---|---|
| Onset | Predictable — same distance or intensity | Unpredictable → reconsider |
| Relief | Minutes of rest | Doesn't settle → escalate |
| Rest | Completely normal | Sore at rest → MTSS |
| Night | Nothing | Night pain → stress fracture, screen |
| Symptoms | Tightness, ache, numbness, foot slap | Cramping with walking in an older adult → claudication |
| Sides | Often bilateral | Strictly unilateral, calf swelling → DVT question |
| Severity | VAS 0–10 at best / at worst / right now | — |
HISTORY
- Training load, surface, footwear, and what changed.
- Military or occupational marching load? It is a recognised population.
- Has anyone measured pressures already, and what were they told?
- Any previous leg injury or surgery?
SPECIAL / SCREENING QUESTIONS
- Does it ever hurt when you're not exercising?
- Calf swelling, warmth, recent immobility, long flight, or a clotting history? DVT.
- Any back pain, or symptoms going into the foot in a band? Lumbar referral.
- Do the symptoms come on with walking rather than running, in an older patient? Vascular.
- Does the timing shift with knee position or ankle position? Popliteal artery entrapment behaves differently.

3 · HYPOTHESIS RANKING
| Competing pattern | The one discriminating feature |
|---|---|
| Medial tibial stress syndrome | Diffuse tenderness present at rest. CECS is normal at rest and only reproduced by exertion. |
| Tibial stress fracture | Focal point tenderness, pain on percussion or hop, persists at rest and at night. |
| Popliteal artery entrapment | Vascular rather than compartmental — check pulses, and consider imaging if the timing doesn't fit. |
| Lumbar referral or nerve entrapment | Back-related behaviour, or a nerve distribution rather than a compartment. |
| Vascular claudication | Walking rather than running, older patient, vascular risk factors, pulses. |
The three that outrank the table
Acute compartment syndrome. Pain out of proportion, not relieved by stopping, progressive neurological signs. Same anatomy, completely different urgency. This is a limb.
DVT. Calf swelling, warmth, recent immobility, a clotting history.
Tibial stress fracture. Rule out MTSS and stress fracture first — it is the common serious mimic, and the one you can miss by accepting an exertional story too readily.
And what the consensus actually says
The Delphi consensus places exclusion of mimics inside the diagnostic process itself [1], alongside history, examination and judicious testing. The differential is not a courtesy step here — it is part of the diagnosis.
4 · RED FLAGS — DON'T MISS THIS
This section is free, on every pattern, forever. Safety is never gated.
| Finding | What it suggests | What you do |
|---|---|---|
| Pain out of proportion, not relieved by stopping | Acute compartment syndrome | EMERGENCY |
| Progressive numbness, weakness or a tense, tender compartment at rest | Acute compartment syndrome | EMERGENCY |
| Pain out of proportion after exertion — with normal pulses | Normal pulses don't clear acute exertional compartment syndrome: 6 of 7 in one series had neurological symptoms, none had a perfusion deficit, and mean time to diagnosis was 97 hours (Livingston et al. 2018) [20] | EMERGENCY |
| Unilateral calf swelling, warmth, recent immobility | DVT | Urgent medical review |
| Absent or asymmetric pulses | Vascular pathology, entrapment | Medical review |
| Focal bony tenderness, night pain, pain on hop | Tibial stress fracture — the anterior tibial shaft is the high-risk site, with more treatment complications than the posteromedial shaft (Hoenig et al. 2023) [21] | Image |
| Progressive weakness or foot drop persisting at rest | Nerve compromise | Urgent medical review |
| Fever, unwell, redness | Infection | Medical review |
| Symptoms with walking in an older patient with vascular risk | Claudication | Medical review |
The rule: exertional compartment symptoms that settle within minutes of stopping, with a normal resting exam, are yours. Anything that persists at rest, progresses, involves swelling, or changes the pulses is not.

More
Anchored to the Delphi consensus statement (Vogels et al. 2022, PMID 35904751) — the closest thing to a guideline this condition has — which places diagnosis on history, examination, exclusion of mimics and judicious testing; to the systematic review of intracompartmental pressure testing (Aweid et al. 2012, PMID 22627653) for why the number is not the diagnosis; and to the systematic review of non-operative management (Rajasekaran & Hall 2016, PMID 27172084) for the conservative trial.
The Vogels consensus is expert agreement, not trial evidence, and it is not an Australian document. The conservative evidence is a systematic review calling itself limited, one case series and one military cohort. The surgical evidence is systematic reviews of cohorts. Nothing on this page rests on a randomised comparison.
