Tibial Bone Stress Injury

Load-related tibial bone stress continuum from periosteal reaction to stress fracture, often associated with abrupt increases in running or impact.

Open Visual Atlas

Structures Involved

  • Tibial cortex and periosteum; anterior cortex and high-risk sites require particular caution.

Mechanism / Why It Happens

  • Repetitive impact exceeding bone adaptation
  • Training-volume/intensity spike
  • Low energy availability, menstrual dysfunction, low bone density or inadequate recovery may increase risk

Classification / Grades

  • Bone stress reaction to stress fracture continuum
  • Low-risk posteromedial tibia versus higher-risk anterior cortex

Symptoms

  • Focal or diffuse tibial pain with running
  • Pain may progress from exercise-only to walking/rest
  • Local bony tenderness

Clinical Signs

  • Focal tenderness
  • Pain with impact may occur but hopping is not a safe exclusion test
  • Gait change in more advanced injury

Red Flags & Referral Clues

  • Pain at rest/night or inability to bear weight
  • Anterior tibial cortex focal pain (higher-risk site)
  • Rapid symptom progression
  • Low energy availability or bone-health concerns

Diagnostic Examination

How to perform the tests — step by step

Each test includes patient setup, therapist position, hand placement, exact performance, positive finding and clinical interpretation.

Clinical Tibial Palpation and Load History

Map tenderness distribution and relate symptoms to recent impact exposure; no single field test rules out stress injury.

Patient position

Review training history and palpate tibia systematically; avoid repeated hopping if stress fracture is suspected.

Therapist position

Position yourself to observe and stabilise the relevant segment without forcing the movement.

Hand placement

Use comfortable, controlled contact appropriate to the test; avoid painful compression or excessive force.

How to perform

  1. 1Explain the test and obtain consent.
  2. 2Screen contraindications and compare sides when appropriate.
  3. 3Perform the movement slowly and apply only the required resistance or stress.
  4. 4Record familiar symptom reproduction, range, strength and side-to-side difference.

Positive sign

Focal bony tenderness with progressive impact-related pain or high-risk history.

Interpretation

Stop impact loading and arrange medical assessment/imaging when bone stress injury is suspected.

Clinical note: A special test modifies clinical probability; it does not confirm a diagnosis in isolation.

Differential Diagnosis

  • Medial tibial stress syndrome
  • Chronic exertional compartment syndrome
  • Tendon injury
  • Vascular entrapment

Investigations / Imaging

  • MRI is preferred when early bone stress injury is suspected and diagnosis affects management; radiographs may initially be normal.
  • Assess bone-health and energy-availability risk factors with appropriate clinicians.

Complete Rehabilitation Plan

From protection to full function

Phase 1 — Protection, Education & Symptom-Guided Loading

Address safety, settle excessive irritability and maintain useful movement.

What to do

  • Stop running/jumping that provokes bone pain
  • Maintain pain-free cross-training only if medically appropriate
  • Assess footwear, training error, nutrition and bone-health risk
  • Use protected weight bearing if walking is painful and clinician advises

Exercise dosage

  • Pain-free cycling/swimming if allowed: 10–30 minutes
  • No impact exercise while walking or daily activity remains painful

Progress when

  • Daily function is stable or improving.
  • No new red flags or progressive neurological deficit.
  • Exercise response returns to baseline by the following day.

Phase 2 — Mobility, Strength & Capacity

Restore the specific strength, mobility and control required by the condition.

What to do

  • Begin progressive strength and low-impact conditioning when daily walking is pain-free
  • Correct training-load and recovery contributors
  • Reintroduce impact only after clinical criteria and risk-site review

Exercise dosage

  • Calf/hip/trunk strength: 2–3 x 8–15, 2–3 days/week
  • Balance and low-impact conditioning

Progress when

  • Target movement and resistance are tolerated with good quality.
  • Functional capacity is improving without sustained symptom flare.
  • Progression is based on objective performance and patient goals.

Phase 3 — Functional Restoration & Return to Activity

Rebuild real-world, occupational or sporting capacity.

What to do

  • Graded walk-run programme with rest days
  • Progress distance before speed/hills
  • Monitor focal pain during and after loading

Exercise dosage

  • Walk-run intervals on alternate days, starting short
  • Increase one variable at a time; regress if focal bone pain returns

Progress when

  • Condition-specific return criteria are met.
  • Full task exposure is completed progressively.
  • No clinically meaningful deterioration during the following 24 hours.

Manual Therapy — Role & Application

  • Manual therapy does not heal bone stress injury and should not be applied over a suspected fracture.
  • Address only secondary mobility deficits after medical clearance.

Modalities — Use / Avoid

  • No modality substitutes for load reduction, bone-health assessment and graded return.
  • Avoid using analgesia to mask pain and continue impact.

Return / Discharge Criteria

  • Pain-free daily walking
  • No focal bony tenderness as judged clinically
  • Risk site and imaging/medical review addressed
  • Progressive running tolerated without recurrence

Common Clinical Mistakes

  • Using hop test to rule out fracture
  • Continuing impact through focal bone pain
  • Ignoring energy availability and bone-health risk
  • Returning by calendar alone

Clinical Pearls

  • Anterior tibial cortex is a higher-risk location than posteromedial tibia.
  • A normal early radiograph does not exclude bone stress injury.
