Spinal tuberculosis complicated by sinus tract
Introduction
Introduction to spinal tuberculosis complicated with sinus Vertebral lesions due to circulatory disorders and tuberculosis infection, bone destruction and necrosis, cheese-like changes and abscess formation, vertebral body collapse due to lesions and weight bearing, causing curvature of the spine, spinous process bulge, hump deformity on the back, thoracic vertebrae Tuberculosis is particularly evident. Spinal tuberculosis accounts for the first place in the system of bone and joint tuberculosis, of which vertebral tuberculosis accounts for the majority, and accessory tuberculosis is very rare. Among the entire spine, the lumbar spine has the highest activity, and the incidence of lumbar tuberculosis is also the highest, followed by the thoracic vertebrae and the cervical vertebrae. The sputum and caudal tuberculosis are rare. Spinal tuberculosis complicated with sinus is one of the most common complications of spinal tuberculosis, with an incidence of 18% before the onset of anti-tuberculosis drugs. The longer the sinus, the shorter the life, and the mortality rate was as high as 34%. Anti-tuberculosis drugs, especially with the introduction of rifampic drugs, have a marked decline in their incidence. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: respiratory transmission Complications: tuberculosis, renal tuberculosis, hip tuberculosis
Cause
Spinal tuberculosis complicated with sinus causes
Causes of sinus formation: Most patients with this disease are self-ruptured on the surface abscess, and the sinus is formed after operation, indicating that the operation period is not properly selected, and the lesion may still be in the stage of exudative disease.
Prevention
Spinal tuberculosis complicated with sinus prevention
Active treatment of tuberculosis, enhance physical fitness, and prevent the spread of tuberculosis are the key to the prevention and treatment of this disease.
Complication
Spinal tuberculosis complicated with sinus complications Complications tuberculosis, renal tuberculosis, hip tuberculosis
The condition is more serious, the average affected vertebral body is 3.1, combined with active tuberculosis, brain, kidney tuberculosis, epididymal tuberculosis, hip tuberculosis, ankle tuberculosis and so on.
In addition, because the patient's resistance is weak, postoperative infection is easy to occur, and active prevention is needed. For patients with drainage tube, leakage can occur in the drainage port, subcutaneous emphysema, exudate and difficulty in breathing.
Symptom
Spinal tuberculosis complicated with sinus symptoms Common symptoms Low fever, dead bones, sweat, purulent secretions increased
Patients with this disease may have typical manifestations of tuberculosis, pus outflow can be found in the fistula, X-ray examination can be found to have obvious vertebral destruction, dead bone, cheese material, or flow abscess, etc., 25% of cases of sinus secretion Positive culture of tuberculosis can be regarded as one of the sources of tuberculosis infection, and it is not difficult to diagnose with bacteriological examination.
Examine
Spinal tuberculosis complicated with sinus examination
The examination of this disease is mainly for laboratory examination of pus, 25% of cases of sinus secretion of tuberculosis culture positive, can be regarded as one of the sources of tuberculosis infection, combined with bacteriological examination is not difficult to diagnose, and bacteriological examination 70 Secondary cases can be found secondary infections, the vast majority (83%) of S. aureus infection, a small number of E. coli and Pseudomonas aeruginosa infection, which is difficult to treat, and the disease is easy to relapse (8.8%) .
Diagnosis
Spinal tuberculosis complicated with sinus diagnosis
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
The disease mainly needs to be differentiated from other types of sinus, but since most patients have a clear history of tuberculosis, the identification is generally not difficult, X-ray examination can also find the diseased spine, tuberculosis test also helps identify.
