Tibial Stress Fracture (Tibial Bone Stress Injury) body chart — Illustrative, not diagnostic. Canva body chart for Tibial Stress Fracture (Tibial Bone Stress Injury).

Who: Runners, recruits, dancers, court and field athletes. Anyone who added load faster than bone could adapt.
What: Focal bony pain that outlasts the activity — and, when it is progressing, shows up at rest and at night.
How it behaves: Aggs: impact, hills, speed, hard surfaces, a training block that stepped up. Eases: nothing quickly. It does not settle between sessions the way MTSS does.

The one thing to take from this page:

Which side of the bone is loaded decides everything. Posteromedial (compression side) gets loaded back up. Anterior cortex (tension side) gets imaged and referred.

Finding	Figure
Prior stress fracture as a risk factor in runners	OR 4.99 (95% CI 2.91–8.56)
Female sex	OR 2.31 (1.24–4.29)
Each 1-point rise in the Triad cumulative risk score → trabecular-rich injury	+26% (p = .0007)
High versus low Triad risk, trabecular-rich sites	RR 4.40 (p = .025)
Asymptomatic collegiate runners with a tibial stress reaction on MRI	43% of 21

([1] [2], prospective, two NCAA institutions, up to 5 years [3].)

⚠️ No Australian guideline exists for tibial bone stress injury. Anchored to the 2025 international Delphi consensus [4] — and a Delphi is not a guideline. No GRADE, no evidence-to-recommendation process, 41 panellists across six continents, consensus on 41 of 58 statements, so seventeen did not reach it. The bone-health arm is anchored separately to the 2025 Female Athlete Triad Coalition update [5][6], which replaces the 2014 statement in full.

Pattern > Label. "Stress fracture" names a tissue. Which cortex, and why the bone was under-built for the load names the problem.

2 · SE — THE SUBJECTIVE PATTERN (the 70%)

This is where the diagnosis is actually made — the exam confirms a hypothesis you already hold.

MAIN PROBLEM

"There's a spot on my shin. It used to hurt at the end of the run, now it hurts from the start."

The trajectory is the pattern. Bone stress narrows and intensifies; MTSS spreads and grumbles.

BODY CHART

P1: one point on the tibia the patient can cover with a fingertip.
Mark it. Then mark how long the tender band is — this is the discriminator, and it is a measurement, not an impression.
"<5 cm" is not a validated threshold — don't use it as one. The only measured figure in this literature is 10 cm or less, from a prospective cohort of 429 elite infantry recruits followed 14 weeks [7]. Everything shorter than that is teaching shorthand.
↑ P at night or at rest = the finding that changes urgency.

BEHAVIOUR

Coding: starts In (intermittent, activity-linked), migrates toward P (present) as the injury progresses.
Irritability — the three parts: resting symptoms present? how much running provokes it? how long to settle? A bone stress injury that hurts at rest and takes hours to settle is a different conversation from one that appears at 8 km.
24-hr pattern: the trend is across weeks, not within a day — and within a session it does not warm up the way MTSS does.
Severity: VAS 0–10 at best / at worst / right now.
The key behavioural question is the trend across weeks, not within a session. MTSS often warms up. Bone stress usually doesn't.

HISTORY

The two questions that carry the most weight, and neither is about the shin:

Question	Why
"Have you had a stress fracture before?"	OR 4.99 (95% CI 2.91–8.56) — the strongest single risk factor in runners
"What changed in the last six weeks?"	Volume, intensity, surface, footwear, hills, a return from a break, a new gym block

Then the load-tolerance side: sleep, illness, exam block, a new job on your feet.

SPECIAL / SCREENING QUESTIONS

Screen bone health directly and without ceremony. This is not optional and it is not only for women.

Energy availability: eating enough for the training load? Deliberate restriction? Weight change?
Menstrual history where relevant — and note that the 2025 Triad update moves away from an energy-availability threshold rather than tightening it [6].
Previous bone stress injuries, fracture history, family history.
Vitamin D and calcium intake, medications, sleep, recovery.
Relative Energy Deficiency in Sport (REDs) is the systemic frame [8].

Patterns > Labels. A runner with a focal shin, a load spike and a restricted diet has a pattern. Which bone it lands in is close to arbitrary.

3 · HYPOTHESIS RANKING

Top three, one discriminating feature each. Rule out the dangerous one first.

Rank	Pattern	The one discriminating feature
1	Medial tibial stress syndrome	Diffuse posteromedial tenderness over a long band, eases with rest, no night pain. See the MTSS page — same shin, different problem.
2	Tibial bone stress injury	Focal tenderness, pain that outlasts the session, rest and night pain, and a load spike or bone-health risk sitting behind it.
3	Chronic exertional compartment syndrome	Symptoms build predictably with exercise and resolve within minutes of stopping. Firm compartment post-run, normal at rest. Often bilateral, often numbness or foot drop.

And the one that isn't a shin problem at all: referred lumbar pain — non-focal, no percussion pain, positive neural tension or lumbar provocation.

The MTSS ↔ bone stress continuum is real, and it is not a licence to wait. Catching it early is the entire clinical value of separating them.

4 · RED FLAGS — DON'T MISS THIS

Free forever. Safety is never gated.

The red flag inside the red flag: which cortex

The anterior tibial cortex is the tension side. It does not behave like the rest of the bone and it does not get managed like the rest of the bone.

Refer early — sports medicine or orthopaedic — for:

Site	Why
Anterior tibial cortex	tension side. Delayed union and non-union
Medial malleolus	44% went to surgery as the initial treatment
Navicular	trabecular-rich, notoriously slow
Base of the fifth metatarsal	tension side
Tension-side femoral neck, pubis, sacrum	not a shin, but the same rule

And be honest about what sits behind that rule. The entire "dreaded black line" convention rests on two studies and thirty-one patients at GRADE low, with no eligible study of initial surgery and no published conservative failure rate [9]. The referral is a reasoned response to an evidence vacuum. It is not a finding.

Medial malleolus — the one with real numbers. 17 studies, 68 patients: initial surgery in 44% (30/68) at a weighted mean 10.1 weeks from onset, with a further 14 patients crossing to surgery after a mean 16.8-week failed conservative trial. Complications 4/30 operative versus 2/38 non-operative. 98% (57/58 reporting) returned to their pre-injury level [10]. A smaller earlier review of 31 patients found no gold-standard treatment at all [11].

The systemic red flag: bone health

Low energy availability, disordered eating patterns, menstrual dysfunction. The 2025 Triad Coalition update states plainly that the bone health spectrum of the Triad now includes bone stress injuries [5].
Lower total-body bone density independently predicted a longer return to sport (p = .030) — it is not only a cause, it is a prognosis [12].
Escalate, don't manage alone: GP, sports physician, dietitian. This is outside a student's scope and it is outside most physios' scope.

The ordinary ones, still

Night pain that is worsening, not just present.
Pain on walking, or an antalgic gait, in someone who was running last week.
Progressive neurological symptoms or a firm, tense compartment → CECS or worse, not bone.
Systemically unwell, unexplained weight loss, night sweats → this stops being a load problem.

The rule: if you cannot tell which cortex, you image. You do not load it and see.

Guideline anchor

No Australian guideline for this presentation.

Anchored to International Delphi consensus on bone stress injuries in athletes (Hoenig et al. 2025, PMID 39638438), paired for the bone-health arm with the 2025 Female Athlete Triad Coalition consensus update, Parts 1 and 2 (PMIDs 41474493 / 41474492)

PubMed

No Australian guideline exists for tibial bone stress injury. No Australian body — ACSQHC, RACGP, Sports Medicine Australia — publishes one. The anchor is international consensus, and it is consensus rather than evidence.
