Роль гленополярного угла в оценке эффективности лечения переломов лопатки

Abstract

Relevance: Scapula fractures are a rare musculoskeletal system injury, accounting for only 0.4–1% of all fractures and approximately 3–5% of all shoulder girdle injuries. Proper visualization plays a key role in determining the severity of a scapula fracture and the choice of further treatment tactics. It allows not only to fully assess the integrity of the body and neck of the scapula, but also to analyze various radiologic parameters, the most important of which is the glenopolar angle (GPA). Aim. To review the values of GPA in patients with different extra-articular types of scapula fractures before and after treatment, and to analyze the correlation of the assessment of treatment efficacy with the values of GPA. Material and methods. We selected 35 patients with extra-articular fractures of the scapula, with damage to the neck and body, including 9 (26%) women and 26 (74%) men. Constant Shoulder Score (CSS) questionnaire scale was used to evaluate the effectiveness of the treatment performed. A value in the range of 30 to 45º was accepted as a normal value of the GPA. Results. After analyzing the radiographs, several groups of patients were formed. After evaluating the treatment efficacy of all patients in the sample, an average CSS score of 81 (good result) was obtained. Group 1 patients achieved on average a good treatment result (μ=84 points), group 2 — good result (μ=82 points), group 3 patients — satisfactory result (μ=75 points). Conclusion. Based on the results of this study, we can conclude that there is a correlation between the value of the GPA and the overall effectiveness of the treatment of scapula fracture. Ignoring the GPA may lead to unsatisfactory results of treatment in the long-term period.
