BURSITIS (from the Late Latin word "bursa", which means "bag" * EN: burcite; DE: Butsitis; FR: bourcite; ES: burcita; RU: бурсит) is the disease, which is associated with the inflammation of the mucous sacs prevalently within the region of the joints. The bursitises of the professional character develop themselves as the consequence of the chronic traumatization of the joints (for example, of the knee and elbow joints) of the miners during the work within the layers with the small thickness, which is associated with the systematic movement on the elbows and knees. The disease manifests itself in the form of the small, dense swelling, which gradually increases, and becomes painful. In case of the chronic bursitis of the knee joint, the swelling is situated on the anterior surface of the patella, while in case of the bursitis of the elbow joint, the swelling is situated within the region of the olecranon of the ulna. For the purposes of the prevention of the bursitis, there is recommended the usage of the knee pads and elbow pads, which are protecting the joints against the traumatization. The healing of the bursitis is limited to the thermal procedures, massage, mud baths, iontophoresis with iodine, and to the punction of the sac, with the subsequent introduction of the hydrocortisone into its cavity. In the cases, which are not amenable to the conservative healing, the surgical operation is suitable, namely, the excision of the sac. The elbow bursitises may be the cause of the temporary, and sometimes of the long-duration disability, but, as a rule, they do not lead to the permanent disability, and may not serve as the cause for the change of the profession. After the surgical operation on the knee joints, there is possible the limited ability to work.
