Abstract

Sumary. The aim is to investigate the features of pathogenesis in capsule formation around metallic foreign bodies of soft tissues.

Materials and methods. The results of a study of 6 patients with metallic foreign bodies of soft tissues with a carrier period of 16 to 50 years were analyzed. 3 injured had foreign bodies of gunshot origin and 3 patients had foreign bodies as a result of personal injury. Used clinical, laboratory, instrumental, histological, immunohistochemical, X-ray spectrometric studies.

Results. All foreign soft tissue bodies were removed with the capsule. By gender: 5 men and 1 woman. By localization - the lower extremity. Pain was present in all the victims. Radiography and ultrasound were informative, magnetodetection is informative only at the superficial location of a foreign body. The foreign bodies were made of gray cast iron and steel needle wire. Histologically, immunohistochemically and radiospectrometrically, it has been found that the capsule formation around the foreign body is affected by the mechanism and extent of damage to the soft tissues, the composition of the metal and its coating, and the carrier term of the foreign body.

Conclusions. Depending on the composition of the metal and its coating, there is a different rate of oxidation of the foreign body in the soft tissues: oxidation of metal foreign bodies of fire origin is faster. The formation of the capsule around the foreign body is affected by the mechanism of tissue damage: when the needle penetrates, the soft tissues are destroyed minimally, in the case of gunshot wounds, they are destroyed more. Spectral analysis data in conjunction with morphological studies are the basis for the removal of a foreign body of inflammatory origin along with the capsule.
