Shin Splints & Stress Fractures: North Beach Physio

Shin splints, clinically known as medial tibial stress syndrome, are one of the most common overuse injuries in runners, dancers, and field-sport athletes. They sit on a spectrum: caught early, they're a 2–3 week deload. Pushed through, they can develop into a stress fracture that puts you out for months. The difference is accurate diagnosis and load management.

Shin Splints vs Stress Fracture

Both present as shin pain that's worse with running. The distinction matters:

Medial Tibial Stress Syndrome (Shin Splints)

Pain over a broad area of the inner shin (usually the lower third). Worse at the start of running, sometimes eases as you warm up, returns afterwards. Diffuse tenderness on palpation.

Tibial Stress Fracture

Pain localised to a specific point on the bone. Often constant: present at rest and with weight-bearing. Worse with each session. Requires imaging (MRI or bone scan) for confirmation and a much longer load-managed return.

What Causes Shin Splints?

• Sudden increase in running volume or intensity
• Change in running surface (e.g. moving from grass to road)
• Worn or inappropriate footwear
• Calf and intrinsic foot weakness
• Biomechanical issues: overpronation, hip control, stride length
• Returning to running too quickly after a break

How We Treat Shin Splints

Diagnosis first. Clinical exam to differentiate from stress fracture. Imaging if there's any clinical suspicion of bone stress.

Load management. We reduce, not eliminate, training load. Cross-training (cycling, swimming) maintains fitness while symptoms settle.

Biomechanical assessment. Running gait analysis, footwear assessment, calf and hip strength testing, addressing what set up the injury in the first place.

Progressive return-to-running plan. Structured week-by-week increases in volume and intensity, with markers for when you can step up.

When to See a Physio

• Shin pain that started after increasing your running
• Pain that's been recurring for more than 2 weeks
• Localised, point-tender pain on the bone (possible stress fracture: get assessed urgently)
• Shin pain in a teenage athlete (bone stress risk is higher)
