väsymisrasituksiin

Väsymisrasituksiin refers to fatigue fractures, a type of stress fracture that occurs when repetitive loading exceeds the bone's ability to repair itself. These fractures are not caused by a single traumatic event but by cumulative stress over time. Common sites for fatigue fractures include the tibia and fibula in the lower leg, the metatarsals in the foot, and the femur in the thigh bone. Athletes, military personnel, and individuals engaging in strenuous physical activities are particularly susceptible.

The development of a fatigue fracture typically begins with micro-damage to the bone. With continued repetitive stress, the rate of damage accumulation outpaces the bone's remodeling process, leading to a complete fracture. Symptoms often include localized pain that worsens with activity and improves with rest, swelling, and tenderness over the affected bone. In some cases, a dull ache may be present even at rest.

Diagnosis usually involves a thorough medical history, physical examination, and imaging studies. While plain X-rays may not show early fatigue fractures, bone scans or MRI can often detect them. Treatment focuses on reducing the load on the affected bone, which typically involves rest, activity modification, and sometimes immobilization with a cast or boot. Gradual return to activity is essential to prevent re-injury. Prevention strategies include proper training techniques, adequate rest and recovery, appropriate footwear, and addressing biomechanical issues.
