False joint (syn: pseudoarthrosis) - persistent violation of bone continuity, causing pathological mobility of its segments. It is usually a complication of fracture of the bone (more often - open or gunshot).

The formation of a false joint is based on violations of fracture healing processes, caused by common and local causes. Common causes include depletion of the body, disruption of the endocrine glands function, lack of vitamins, neurotrophic disorders, etc., local - infection of the fracture, significant defects in soft tissues and bones, impaired blood supply and innervation of fragments, interposition (penetration of soft tissues between fragments), wrong Treatment associated with unsatisfactory reposition and fixation of fragments.

Clinically, the false joint manifests itself as a painless or painless mobility in the place of the former fracture, the absence of the fusion of the fragments after a considerable time after the injury, and the violation of limb function. X-ray reveals a gap between the fragments and the closure of the medullary canals with bone substance. In a long-term false joint, typical articular surfaces covered with cartilage are sometimes formed; The surrounding fibro-altered tissues form a capsule of the joint.

Treatment is only prompt; It usually consists in removing fibro-altered soft tissues between fragments, resection of the ends of fragments, opening of the medullary canal and strong fixation of fragments with the help of various methods of osteosynthesis, distraction-compression apparatuses, plaster bandages.
