Things worth knowing about "Shin splints"
Shin splints is a common overuse injury causing pain along the inner edge of the shinbone, frequently affecting runners and athletes. It is also known as medial tibial stress syndrome.
What are Shin Splints?
Shin splints, medically referred to as medial tibial stress syndrome (MTSS), is a painful overuse condition affecting the inner edge of the shinbone (tibia). It is one of the most common sports-related injuries, particularly among runners, military recruits, and individuals participating in high-impact activities. The condition arises from repetitive stress on the bone, muscles, and surrounding connective tissue of the lower leg.
Causes
Shin splints typically develop when the lower leg is subjected to repeated mechanical stress that exceeds the body's ability to recover. Common contributing factors include:
- Rapid increases in training volume or intensity without adequate adaptation time
- Worn-out or inappropriate footwear that fails to provide sufficient support and cushioning
- Hard training surfaces such as concrete or asphalt
- Muscle weakness or imbalances in the lower leg, hip, or core
- Foot biomechanics issues, such as overpronation (excessive inward rolling of the foot)
- Insufficient recovery time between training sessions
- Anatomical factors such as flat feet or lower limb malalignment
Symptoms
The hallmark symptom of shin splints is pain along the inner border of the shinbone, which may extend over several centimetres. Typical symptoms include:
- Aching or dull pain on the inner edge of the shin
- Pain that appears at the start of exercise, sometimes eases during activity, but returns after training
- Tenderness to the touch along the shinbone
- Mild swelling or a sensation of warmth in the affected area
- In advanced cases: pain even at rest
Important: Persistent or severe pain should be evaluated by a healthcare professional to rule out a stress fracture of the tibia, which is a more serious condition requiring different management.
Diagnosis
Diagnosis is primarily clinical, based on patient history and physical examination. Depending on the severity and clinical picture, additional investigations may be used:
- Palpation of the shinbone to localise tenderness
- X-ray to rule out fractures or bony abnormalities
- MRI (Magnetic Resonance Imaging) for unclear presentations or suspected stress fracture
- Bone scintigraphy in selected cases to assess bone metabolism and identify stress reactions
Treatment
Conservative Treatment
The vast majority of cases respond well to conservative management. Key treatment strategies include:
- Relative rest and activity modification: Reducing or temporarily stopping high-impact activities. Low-impact alternatives such as swimming or cycling are usually well tolerated.
- Ice therapy: Applying an ice pack to the affected area helps reduce pain and local inflammation.
- Physiotherapy: Targeted strengthening of the lower leg and hip muscles, stretching exercises, and gait analysis to address biomechanical issues.
- Orthotic insoles: Custom foot orthotics may help redistribute load in individuals with foot alignment problems.
- Appropriate footwear: Well-cushioned and supportive running shoes are essential for recovery and prevention.
- Pain management: Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen may be used short-term for pain relief.
Return to Sport
A gradual return to sport should only begin once the athlete is fully pain-free. A structured progressive loading programme guided by a physiotherapist or sports medicine physician is strongly recommended to prevent recurrence.
Surgical Treatment
Surgery is rarely required. In exceptional cases where conservative treatment has failed after several months, a procedure known as fasciotomy (releasing the connective tissue surrounding the muscle compartment) may be considered.
Prevention
Shin splints can often be prevented with the following measures:
- Gradual and progressive increase in training load (applying the 10% rule per week)
- Regular replacement of running shoes and selection of appropriate footwear
- Strengthening exercises for the lower leg, hip, and core muscles
- Adequate rest and recovery between training sessions
- Varying training surfaces to avoid repetitive impact on hard ground
- Running technique analysis and optimisation
