**False joint** dangling (syndromus adhaerens multiarticularis, syndromus pseudo adhaerences multiplexer) is a surgical complication during orthopedic treatment of a false joint. It occurs as a result of ongoing diastasis of the ends of the fragments after fusion of the articular surface; the ends of the fragments, under the pressure of purulent-necrotic tissue, begin to separate from each other, shortening and loosening of the ends of the fragments, and movement occurs. In the joint it occurs in any plane, the range of motion is very large, granulating tissue destroys the joint capsule (in adolescents), articular surfaces (adolescence).
As a rule, the spinal joint begins to hurt immediately after surgery or in the first days after it, but sometimes its symptoms do not appear for a long time.
**The patient complains** of excruciating pain in the area of the postoperative scar, worsening at night, a feeling of constant heaviness, looseness in the operated joint, and impaired movement function. When palpating, the surgeon establishes that the ends of the broken bones are mobile and effortlessly move one above the other. On radiographs, the bone tissue defect has unclear outlines and there is no periosteal reaction. The defect appears again if the site where the granulating material was removed is covered with bone meal.
A false joint is a group of flat joints that occupy an intermediate position between true joints and trochlear joints. This term was coined to emphasize the fact that even with a significant divergence of the ends of the bones being fastened, as during normal joint movements, there is no true (physiological) movement between
