Optimization of surgical treatment tactics at a customary shoulder dislocation

The aim: the optimization of surgical treatment tactics at a customary shoulder dislocation, based on "on-track Hill-Sachs / off-track Hill-Sachs" concept. Material and Methods. The research group consists of 42 patients aged from 19 to 52 years with chronic recurrent anterior shoulder instability, who underwent a surgical treatment to restore previous shoulder anatomic and topographic correlations. Patients were divided into two subgroups according to diagnostic arthroscopy results. The first subgroup includes 14 patients with impaction visualized (off-track Hill-Sachs), the second one — 28 patients with head shoulder stability (on-track Hill-Sachs). Patients of the first subgroup underwent open surgical intervention according to Bristow — Latarjetand shoulder arthroscopic repair was carried out in the second group. Results. One month after the surgical treatment median total estimated figure exceeded by 1.8 times in patients of the first subgroup and by 1.2 times, by Rowe, in patients of the second subgroup and decreased by 2.1 times in patients of the first subgroup and by 1.7 times, by DASH, in the second subgroup in comparison with the indices before the operation, that was illustrative of a good treatment result. Six months after the operation median total estimated figure exceeded by 1.2 times, by Rowe, in patients both of the first subgroup and the second subgroup and decreased by 2 and 2.1 times, by DASH, in patients of the first and the second group, relatively in comparison with the indices found one month after the operation, that was illustrative of an excellent treatment result in the late postoperative period. Conclusion. Patients with anterior shoulder instability caused by a glenoid fossa deficiency less than 25% in combination with off-track Hill-Sachs lesion, the most convenient way is the replacement of the bone loss by coracoid process transposition. In patients with on-track Hill-Sachs lesion arthroscopic repair is preferable.
