Fatigue fractures in track athletes

Area of Science:

• Sports Medicine
• Orthopedics
• Biomechanics

Background:

• Fatigue fractures, also known as stress fractures, are common in athletes engaging in repetitive high-impact activities.
• Track athletes, particularly middle-distance runners, exhibit a high incidence of these injuries, often linked to training intensity and track surface hardness.

Purpose of the Study:

• To describe the initial symptoms, diagnostic challenges, and treatment outcomes of fatigue fractures in track athletes.
• To identify risk factors and propose preventive measures for fatigue fractures in this population.

Main Methods:

• Clinical observation of track athletes presenting with foot or lower leg pain.
• Radiographic imaging (X-rays) at symptom onset and follow-up (one month or later).
• Analysis of training habits, including running volume, intensity, and track surface type.

Main Results:

• Initial X-rays may appear normal, with abnormalities like callus formation or fracture lines becoming visible weeks later.
• Cessation of running for at least two months is the primary treatment, leading to recovery.
• Intensive training, especially by quartermilers, and hard running tracks are associated with higher incidence.

Conclusions:

• Early diagnosis can be challenging due to delayed radiographic findings.
• Conservative management involving rest is effective for fatigue fractures.
• Preventive strategies include modifying training schedules (e.g., alternate days) and incorporating softer running surfaces like grass.
