Subkorakoid sıkışmada, korakoid morfolojisinin, korakohumeral mesafenin, korakoglenoid açının ve korakohumeral açının MRG ile değerlendirilmesi

Öz

Amaç: Bu çalışmanın amacı, korakoid morfolojisi, korakohumeral mesafe,korakoglenoid açı ve korakohumeral açı değişkenlerinin subkorakoid sıkışma gelişimi üzerine etkileri manyetik rezonans (MRG) ile değerlendirilmektir. Gereç ve Yöntem: Retrospektif çalışmaya omuz MRG çekilen toplam 255 hasta (ort. yaş 51.25±15.77 olan 115 erkek ve ort.yaş 53.13±14.75 olan 140 kadın) alındı. MRG incelemeleri standart pozisyonda yapıldı. Korakoid morfolojisi ve subskapularis tendonu değerlendirildi. Tüm olgularda korakohumeral mesafe, korakoglenoid açı ve korakohumeral açı ölçüldü. Gruplar arasındaki farkı değerlendirmek için tek yönlü ANOVA kullanıldı. İkili karşılaştırmalar için, Tukey post hoc analizi yapıldı. Değişkenler arasında Pearson korelasyon analizi yapıldı. Bulgular: Subskapularis tendonu yırtık olan grupta en sık Tip C korakoid görüldü. Korakohumeral mesafe, korakoglenoid açı ve korakohumeral açı değerleri için korakoid tipleri arasında istatistiksel olarak anlamlı bir fark saptanmadı (p> 0.05). Subskapularis tendon yırtığı olan hastalarda korakoglenoid açı değerlerinde ve korakohumeral mesafede istatistiksel olarak anlamlı bir azalma vardı (p= 0.000). Korakohumeral açı değeri için tendonu normal olanlar, tendinozis olanlar ve yırtık olan grupların ortalamaları arasında fark yoktu (p>0.05). Korakohumeral mesafe ile korakoglenoid açı arasında pozitif yönlü korelasyon bulundu (r=0.239, p<0.001). Korakoglenoid açı ile korakohumeral açı arasında negatif yönlü korelasyon bulundu (r=-0.320 , p<0.001). Sonuç: Subskapularis tendon patolojilerinde korakohumeral mesafe ve korakoglenoid açıda azalma gözlendi. Tip C korakoid subkorakoid sıkışmada etkili ve önemli bir faktördür.

MRI evaluation of coracoid morphology, coracohumeral distance, coracoglenoid angle and coracohumeral angle in subcoracoid impingement

Öz

Aim: This study aimed to evaluate the effects of coracoid morphology, coracohumeral distance,coracoglenoid angle, and coracohumeral angle on subcoracoid impingement using MRI.

Material and Method: A total of 255 patients (115 men with a mean age of 51.25±15.77 years and 140 women with a mean age of 53.13±14.75 years) were included in this retrospective study. All MRI examinations were performed in the standard position. Coracoid morphology and subscapularis tendon were evaluated. Coracohumeral distance, coracoglenoid angle, and coracohumeral angle were measured in all cases. One-way ANOVA was used to analyze the differences between the groups. The Tukey post-hoc test was performed for paired comparisons. The Pearson correlation analysis was undertaken to demonstrate the relationship between the variables. Result: Subscapularis tendon rupture was the most common type C coracoid. Coracohumeral distance, coracoglenoid angle and coracohumeral angle values did not significantly differ according to coracoid types (p>0.05). However, there was a statistically significant decrease in coracoglenoid angle and coracohumeral distance values in patients with subscapularis tendon rupture (p=0.000). No difference was found in the mean coracohumeral angle values between the normal tendon, tendinosis and rupture groups (p>0.05). There was a positive correlation between coracohumeral distance and coracoglenoid angle (r=0.239, p<0.001), and a negative correlation between coracoglenoid angle and coracohumeral angle (r=-0.320, p<0.001). Conclusion: Coracohumeral distance and coracoglenoid angle were observed to decrease

in subscapularis tendon pathologies while the coracohumeral angle had not changed. Type C coracoid is an effective and important factor in subcoracoid impingement.
