Dislocation Incomplete

**Incomplete dislocation**

Incomplete dislocation of the radial head is defined as an unnatural displacement of the articular surfaces of the head and radial neck without compromising the integrity of the joint capsule. At the same time, from 3 to 19 mm of displacement of one articular surface relative to the other and a violation of congruence in the joint remain. When moving the hand, limited mobility is noted, not exceeding the norm on one side. On an x-ray, it is possible to determine the divergence of the axes of the radius and ulna by 40°. The curvature of the axis of the radius for unnatural displacement of the neck in the head without displacement under the influence of load reaches 1-2°, for dislocation under the influence of a sudden load (chlo
