navicular fracture
Introduction
Introduction to the scaphoid fracture The middle ankle joint, which is composed of the foot scaphoid, the wedge bone and the tibia, is also called the transverse joint. It is easy to cause dislocation due to trauma. Although the above-mentioned simple fracture of the bone is not frequent, it is not uncommon. About 0.3% of all body fractures should still be noticed. A fracture occurs at a distance through longitudinal conduction, leverage, or torsion, such as a compression fracture when the foot falls from a height. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: shock
Cause
Cause of scaphoid fracture
Direct violence (30%):
Violence directly affects a part of the bone and causes fractures in the part, which often causes fractures in the injured area, often accompanied by varying degrees of soft tissue destruction. If the wheel hits the calf, a fracture of the humerus shaft occurs at the impact.
Accumulated strain (30%):
Long-term, repeated, mild direct or indirect injury can cause a specific part of the limb to fracture, such as long-distance marching to cause the second, third metatarsal and the lower third of the humerus fracture.
Prevention
Foot scaphoid fracture prevention
For patients who have been injured for 1 to 2 weeks, the diet needs to be light, easy to absorb and digest. They should be given more vegetables, fruits, fish soup, eggs, soy products, etc., and should be mainly steamed or stewed. Eat spicy, greasy and fried foods. In particular, you can eat more honey and bananas, because most patients in bed will have symptoms such as constipation, these foods can help defecation.
Complication
Foot scaphoid fracture complications Complications
(1) Shock: severe injury, caused by major bleeding or major organ damage.
(2) Fat embolism syndrome: occurs in adults, due to excessive tension in the hemorrhage of the sacral cavity in the fracture, fat drops into the ruptured sinus, can cause lung and brain fat embolism.
(3) Important internal organ damage: 1 liver and spleen rupture. 2 chest and lung injury. 2 bladder and urethral injury, intestinal damage.
Symptom
Symptoms of scaphoid fractures Common symptoms Severe pain When the toes stretch and flex, the foot is swollen and the back is swollen for a long time or intensely...
1. Pain and swelling : The pain of the foot is obvious when the toe is flexed and flexed. Because the muscle tissue of the part is less covered, local swelling and soft tissue congestion are more obvious.
2. Axial pain: When the 1-3 bones are pushed longitudinally, the middle jaw is severely painful.
Examine
Foot scaphoid fracture examination
All patients with suspected fractures should be routinely X-ray film examination, which can be found in clinically difficult to find incomplete fractures, deep fractures, intra-articular fractures and small avulsion fractures, even if they have clinically manifested as obvious fractures. X-ray film examination is also necessary to help understand the type and specific conditions of the fracture, and has guiding significance for treatment.
Diagnosis
Diagnosis and differentiation of scaphoid fracture
1. History of trauma.
2, clinical features: mainly for the swelling of the back of the foot, pain and 1 ~ 3 tibia axial thrust caused by the pain of the middle and the ankle joint.
3, imaging examination: generally do not need CT, MRI and other examinations, and only need regular X-ray film to confirm the diagnosis, there is a need for X-ray oblique film.
The scaphoid nodule fractures should be differentiated from the scaphoid bone. The latter is congenital developmental, with smooth and tidy edges, similar to joints.
