Long-term results of the rotator cuff tears treatment after anterior shoulder dislocation in middle-aged and senior patients

Introduction: More than 20% of shoulder dislocations occur in individuals over 40 years of age. Current treatment algorithms for shoulder dislocation management include conservative treatment with immobilization and subsequent rehabilitation, which leads to an unsatisfactory result (decreased function, pain) in more than 50% of older patients. It is associated with damage to the rotator cuff tendons (RCT) and subsequent muscle degeneration. The aim of the study was to improve the results of the diagnosis and treatment for patients over 45 years of age with primary traumatic dislocation of the shoulder with varying degrees of RCT damage.Materials and methods: 85 patients (60.2±11.4 years, 44 men, 41 women). Inclusion criteria: fi st-time dislocation, consent to participate in the study. Radiographs and magnetic resonance imaging (MRI) of the shoulder joint were performed with assessment of the subacromial space and acromiohumeral index (AHI). Next groups were formed: Comparison group 1 (rehabilitation treatment of full-thickness RCT damage, 18 people), comparison group 2 (rehabilitation treatment of partial-thickness RCT damage, 21 people), study group (surgical treatment of full-thickness RCT damage, 24 people). Also, to reduce damage to the RCT muscles, 2 comparable groups were randomly formed: group taking a mixed amino acids (leucine:isoleucine:valine) and group taking placebo.Results: a signifi ant correlation between the AHI and the width of the subacromial space (Pearson's rxy = 0.895, p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
