Coxalgia is the term now used to describe coxo-femoral tuberculosis, i.e. hip arthritis originating from tuberculosis. Coxalgia of tuberculosis origin affects the child and its treatment consists of refraining from walking combined with tuberculosis drugs. This disease is relatively uncommon in France. The term "sciatica" is nevertheless still used to talk about hip pain from all causes. It can be due to a degenerative disease of the hip joint called osteoarthritis or more specifically inflammatory arthritis, infectious in origin or secondary to trauma.


In general, the term sciatica etymologically refers to pain in the hip. Clinical signs may be encountered:
  • pain in the hip, either spontaneously or only during mobilization or walking, or increased by other stress on the joint;
  • Joint mobility is usually limited by pain and stiffness of the lower limb is observed;
  • The hip may appear red, with swelling and an increase in heat;
  • Other signs may be present and cover the problem at hand, such as fever, the presence of lymph tissue, deformation, abnormal spontaneous positions or a shortening of the leg ...


The doctor conducts a physical examination of the patient. After examination of the hip via palpation and an examination of mobilization, he will also look at the leg, pelvis, and monitor walking if it is possible. Generally, the first results tests will be an X-ray of the pelvis to potentially highlight osteoarthritis or fracture. Blood tests may be prescribed, looking for markers of inflammation. An ultrasound of the joint is also possible, and a joint biopsy may be necessary. The analysis of joint fluid may confirm the presence of infection, or tuberculosis.


In general, resting the affected joint is required. Pending specific treatment, painkillers are needed. In case of a fracture, surgery is often performed, and a hip replacement can be done, which is also possible in the case of advanced osteoarthritis. Antibiotics or TB treatment will be administered in cases of infectious arthritis, sometimes accompanied by surgery.


In the case of tuberculosis sciatica, a prevention of the infection exists in the form of the BCG vaccine, recommended in populations at high risk of exposure to this disease.
