Fatigue fracture of metatarsal
Introduction
Introduction to tibia fatigue fracture Track and field athletes will have a lot of stress when running, especially the first and second metatarsal bones. The second, third, and fourth metatarsal bones are prone to fractures due to their weaker metaphysis. Risk factors include arched feet, shoes with poor vibration damping, and osteoporosis. The negative focus of the foot is transferred from the first metatarsal head to the second metatarsal head. However, the first metatarsal bone of the second metatarsal shaft is slender and therefore prone to fatigue fracture. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: restless legs syndrome
Cause
Causes of tibia fatigue fracture
1. Chronic injury, long-term concentrated stress is the condition for fatigue fracture.
2, this patient found in the X-ray film, the majority of patients with the first metatarsal development is short, the second metatarsal is relatively long; in addition, the clinical examination found that the first, the second metatarsal bone structure loose, so that the negative focus of the foot The first metatarsal head is transferred to the second metatarsal head. However, the first metatarsal shaft of the second metatarsal shaft is slender and thin, so fatigue fracture is prone to occur.
Prevention
Tibial fatigue fracture prevention
The treatment of fatigue fractures is the same as that caused by traumatic violence:
Early firm fixation is used in conjunction with rehabilitation training.
For those more advanced fatigue fractures, due to hyperplasia of the fracture end, fracture healing is difficult, and an auxiliary method can be adopted to promote bone healing.
Complication
Tibial fatigue fracture complications Complication, restless leg syndrome
Sometimes the patella dislocation is visible.
Due to the muscle and ligament traction, the broken end is displaced, and the treatment is not well reset, and malformation may occur.
Symptom
Tibial fatigue fracture symptoms Common symptoms Long or severe... Foot swelling, tenderness, fatigue, foot, walking, dysfunction, emotional fatigue
The patient usually has pain in the forefoot after prolonged or strenuous exercise. After a few seconds of rest, the pain disappears. In the subsequent training, the pain occurs earlier and more severely, so that it can't exercise, and even there is pain in bed. Feeling, touching the swollen part can cause pain. The X-ray usually can not show the fracture, and even after 2 to 3 weeks, the epiphysis is formed. Usually, the bismuth diphosphate bone scan is helpful for diagnosis.
Examine
Examination of tibia fatigue fracture
Take a positive, oblique x-ray to determine the diagnosis. Usually the bismuth diphosphate bone scan is helpful for diagnosis.
Diagnosis
Diagnosis and diagnosis of tibia fatigue fracture
Fatigue fracture and trauma violence: tibiofibular fracture and calcaneus fracture, phalangeal fracture.
