[Chronic recurrent instability of the shoulder joint].

The article gives an analysis of results of conservative treatment of 503 patients with a primary traumatic dislocation of the shoulder. High frequency of the development of chronic instability of the shoulder joint was shown to be 31.2%. The using of arthroscopy, noninvasive methods of diagnosis (rentgenography, USI) allowed to diagnose the typical complex of morphological injuries following dislocations of the shoulder. General and local factors responsible for the development of chronic instability of the shoulder joint were established. Arthroscopy and early surgical stabilization of the joint are thought to be expedient in cases of a combination of these factors. Conservative treatment is indicated to patients older than 40 without high physical needs.
