Abstract


Background. Shoulder arthroplasty is one of the widespread surgeries in the world. In Ukraine, the number of the shoulder joint arthroplasties is negligible and does not exceed 30 operations per year. The purpose of our work was to investigate the results of shoulder arthroplasty in patients with deforming arthrosis of the shoulder joint of 3–4 J. Kellgren stage, with polyfragmental intraarticular fractures of the proximal humerus and their consequences. Materials and methods. The clinical group consisted of 108 patients who underwent total unipolar shoulder joint arthroplasty in the period from 2006 to 2016 in the department of microsurgery and reconstructive surgery of the upper extremity of State Institution “Institute of Traumatology and Orthopedics of NAMS of Ukraine” (Kyiv). All patients were divided in to three groups: group A — patients with deforming arthrosis of the shoulder joint of 3–4 J. Kellgren stage, group B — patients with polyfragmental intraarticular fractures of the proximal humerus, group C — patients with the consequences of polyfragmental intraarticular fractures of the proximal humerus. The evaluation of the shoulder joint function was performed with the Constant Shoulder Score and Oxford Shoulder Score prior to the surgery (except for group B) and 3, 6, 12, and 18 months after the operation. In the vast majority of patients, we applied unipolar prosthesis. We used Stryker or Biomet endoprostheses. All patients used a standard rehabilitation program that was developed in our clinic. Results. Shoulder arthroplasty enables significant improvement in shoulder joint function in patients over 50 years with deforming arthrosis of the joint, with polyfragmental intraarticular fractures of the proximal humerus and their consequences (p < 0.01). The best average results of shoulder joint arthroplasty according to Constant Shoulder Score and Oxford Shoulder Score were obtained in group A (patients with deforming arthrosis of the shoulder joint). The average increase in the function of the shoulder joint in patients of group A six months after surgical treatment was 21.0 ± 2.8 points (p < 0.05) and 10.0 ± 2.1 points (p < 0.05), respectively. The worst results on the Constant Shoulder Score and Oxford Shoulder Score were received in group C (patients with consequences of polyfragmental intraarticular fractures of the proximal humerus). The average increase in the function of the shoulder joint in patients from group C six months after surgery was only 18.0 ± 3.9 points (p < 0.05) and 6.0 ± 1.9 points (p < 0.05), respectively.
