Lower Leg

Shin

Shin pain involves the tibialis anterior, tibialis posterior, and the periosteum of the tibia. Shin splints (medial tibial stress syndrome) are extremely common in runners and military recruits, typically caused by rapid increases in training load.

Common Causes

1

Shin splints (medial tibial stress syndrome) from overuse

2

Tibialis anterior strain from excessive walking or hill running

3

Compartment syndrome from increased pressure in the shin compartment

4

Tibial stress fracture from repetitive impact

5

Periostitis from running on hard surfaces

Muscles in This Area

Lower Leg

tibialis anterior

The tibialis anterior is a long, thin muscle running down the front of your shin from knee to ankle. It lifts your foot upward (dorsiflexion) and turns it inward (inversion), crucial for walking, running, and preventing your toes from dragging. Strong tibialis anterior prevents shin splints and improves ankle stability for better athletic performance.

Lower Leg

tibialis posterior

Hidden deep in the calf behind the tibia, the tibialis posterior supports your arch and stabilizes the ankle. It inverts the foot and assists plantarflexion, vital for push-off in running and preventing flat feet. Weakness leads to overpronation and foot pain during activity.

Lower Leg

extensor digitorum longus

The extensor digitorum longus runs lateral shin from knee to foot, extending toes 2-5 and dorsiflexing ankle. Builds shin definition for runners.

Lower Leg

extensor hallucis longus

The extensor hallucis longus runs down the front of the lower leg and extends the big toe while also assisting in dorsiflexion of the ankle. It's crucial for clearing the foot during the swing phase of gait in runners and athletes. Strong EHL prevents foot drop and enhances explosive movements like jumping.

Lower Leg

fibularis longus

The fibularis longus runs along the outer lower leg, crossing under the foot to evert and stabilize the arch. It powers push-off in sprinting and side-to-side movements. Crucial for runners to avoid ankle sprains and maintain foot alignment.

Broad flat muscle deep to gastrocnemius in calf, plantarflexes ankle for standing/walking. Powers propulsion in running/squats; endurance king.

When to See a Doctor

Seek medical attention if shin pain worsens despite rest, is localized to a specific spot on the bone, is accompanied by numbness or tingling in the foot, or causes swelling that feels tight and firm.

Self-Care Tips

1

Reduce running volume and avoid hard surfaces

2

Stretch the calf and shin muscles before and after activity

3

Strengthen the tibialis anterior with toe raises and heel walks

4

Ensure proper footwear with adequate support
