What Is Medial Tibial Stress Syndrome?

Diagnosing Medial Tibial Stress Syndrome

Shin splints is a term often used to describe nearly all lower leg pain occurring below the knee in the shin region. Diagnosis is usually made based on a patient’s history and physical examination, often without needing scans or imaging. Medically known as medial tibial stress syndrome, shin splints are frequently the result of one main issue: “too much, too soon.”

This condition is common in those new to running or returning after a break. They often increase their training volume too quickly without allowing their tissues time to adapt. In more experienced runners, shin pain may follow abrupt changes in routine, such as increasing mileage too fast, switching from soft to hard surfaces, starting hill training, or changing shoes in terms of pitch or stability. All of these can contribute to overload.

With medial tibial stress syndrome, common signs include:

• Tenderness or soreness along the inside of the lower leg when touched.
• Mild swelling may also be present in the same area.

Initially, pain may only occur during activity and subside with rest. However, if left unmanaged, the pain can progress and remain even at rest. It’s important to note that not all shin pain equals medial tibial stress syndrome. Other conditions, including stress fractures, tenosynovitis, and compartment syndrome, may present similarly and should be ruled out.

• Tests such as X-rays, MRIs, bone scans, or compartment pressure testing can help confirm or exclude other causes. These are generally not required but may be helpful if symptoms are atypical or diagnosis remains uncertain after clinical examination.

Differential Diagnosis of Shin Splints

Several conditions can resemble medial tibial stress syndrome and may be misdiagnosed, leading to ineffective treatment. These include:

Anterior Compartment Syndrome: Pain at the front or outside of the lower leg could indicate compartment syndrome. During exercise, increased blood flow causes muscle swelling within a confined compartment, raising pressure and causing pain. Diagnosis typically involves a pressure test. Surgery may be required if physiotherapy fails. Pain from this condition typically builds gradually and subsides quickly after stopping activity.

Tibial Stress Fractures: These are more serious than medial tibial stress syndrome and require careful management. They can be confirmed with X-rays, MRIs, or bone scans, which help distinguish between stress fractures and other causes of shin pain.

Tenosynovitis: Inflammation of a tendon sheath can result from injury to the tendon or nearby tissue. When affecting the front of the shin, it can mimic the symptoms of medial tibial stress syndrome.

Treatment of Medial Tibial Stress Syndrome

The first step in treatment is to rest from painful activities, giving the body time to recover. This can be balanced with lower-impact activities like swimming, aqua jogging, cycling, or using an elliptical or rowing machine to maintain fitness.

• Applying ice daily to the affected area can help relieve pain and reduce swelling. Anti-inflammatory medications like ibuprofen or Voltaren may also assist during the early stages.
• Returning to sport should be gradual. Rushing back into full training too soon can cause setbacks. A physiotherapist can guide you on when and how to resume activity safely.

Following assessment, your physiotherapist may recommend changing footwear or using orthotics to optimise lower limb alignment and reduce load on irritated tissues. A program combining stretching and strengthening exercises often supports more efficient movement and helps alleviate stress on the shin. Taping techniques or wearing shin splint sleeves can also be beneficial for symptom relief.

• Dry needling and shockwave therapy are physiotherapy options frequently used at Sydney Physio Clinic to support shin splint rehabilitation, particularly in our active city-based patients.

Preventing a Recurrence of Shin Splints

If you’ve experienced shin splints, there’s a chance the pain could return, especially without proper preventative steps. These strategies may help reduce your risk:

• When resuming training after a break or modifying your program (e.g., increasing mileage, changing surfaces, or switching footwear), avoid increasing load by more than 10% per week. Gradual changes give your body time to adapt.
• If you’re prone to medial tibial stress syndrome, incorporate regular calf and Achilles stretches into your routine to minimise strain on the lower legs.
• Replace running shoes before they show excessive wear. Worn-out shoes may impair biomechanics and contribute to injury.
• A running assessment with a sports podiatrist can identify and correct movement patterns that place excessive stress on your shins and other joints.
