Is There A Relationship Between Critical Shoulder Angle and Fatty Degeneration and Number of Damaged Tendons in Rotator Cuff Arthropathy Patients?

Öz

The aim of this study was to investigate the correlation of critical shoulder angle (CSA) in rotator cuff arthropathy patients with number of damaged rotator cuff tendons and muscle fatty degeneration. Rotator cuff arthropathy patients were included in this study. True antero-posterior radiographs (Grashey view) were used to measure the angle by the first author. The critical shoulder angles were measured on radiographs. The Magnetic resonance images (MRI) of same patients were assessed in terms of number of tendon involvements and fatty degeneration of rotator cuff muscles. There were 28 rotator cuff arthropathy patients comprising 16 females and 12 males. The mean age was 69.928.84 years. The right shoulder was affected in 20 patients. The left side was affected in 8 patients. The damaged rotator cuff tendons were as follows; supraspinatus tendon was affected in all patients, infraspinatus tendon was affected in 25 patients, teres minor was affected in 14 patients, and subscapularis tendon was affected in 24 patients. The critical shoulder angle was found 37.601.66 CSA values were found to be higher in patients having fatty degeneration than others having no fatty degeneration, and it was statistically significant (p<0.001). The CSA values were found to be higher in patients with having increased number of damaged tendons and with having fatty degeneration of rotator cuff muscles. The higher CSA means the worse rotator cuff arthropathy patients, therefore care should be taken for planning surgical treatment options.

Rotator manşet artropatili hastalarda kritik omuz açısı ile yağlı dejenerasyon ve hasarlı tendon sayısı arasında ilişki var mıdır?

Bu çalışmanın amacı rotator manşet artropatili hastalarda kritik omuz açısının (KOA) hasarlı rotator manşet tendon sayısı ve kasların yağlı dejenerasyonu ile ilişkisini araştırmaktı. Rotator manşet artropatisi hastaları bu çalışmaya dahil edildi. İlk yazar tarafından açıyı ölçmek için gerçek ön-arka radyografiler (Grashey görünümü) kullanıldı. Kritik omuz açıları radyografilerde ölçüldü. Aynı hastaların Manyetik rezonans görüntüleri (MRG), tendon tutulumlarının sayısı ve rotator manşet kaslarının yağlı dejenerasyonu açısından değerlendirildi. 16 kadın ve 12 erkekten oluşan 28 rotator manşet artropati hastası vardı. Ortalama yaş 69.928.84 idi. 20 hastada sağ omuz etkilenmişti. 8 hastada sol taraf etkilenmişti. Hasarlı rotator manşet tendonları şu şekildeydi; Hastaların tamamında supraspinatus tendonu, 25 hastada infraspinatus tendonu, 14 hastada teres minör ve 24 hastada subskapularis tendonu etkilenmişti. Kritik omuz açısı 37.601.66olarak bulundu. Yağlı dejenerasyonu olan hastalarda KOA değerleri, yağlı dejenerasyonu olmayanlara göre daha yüksek bulundu ve istatistiksel olarak anlamlıydı (p<0,001). Hasarlı tendon sayısı fazla olan ve rotator manşet kaslarında yağ dejenerasyonu olan hastalarda KOA değerleri daha yüksek bulundu. Daha yüksek KOA, daha kötü rotator manşet artropati hastaları anlamına gelir, bu nedenle cerrahi tedavi seçeneklerinin planlanması için özen gösterilmelidir.
