Omuz iç rotasyonunun korakohumeral ve akromiyo aralığa etkisinin üç boyutlu tomografi ile değerlendirilmesi

Amaç: Bu çalışmanın amacı korakohumeral aralık ve akromiyohumeral aralık miktarının omzun pasif iç rotasyonu ile gerçekten azalıp azalmadığını değerlendirmektiGereç ve Yöntem: Çalışmada Mayıs 2016 ile Ekim 2016 arasında poliklinikte rotator kılıf hasarı ön tanısı ile bilgisayarlı tomografi artrografi çekilen hastalar kullanıldı. Bilgisayarlı tomografi artrografi tetkiki omuz nötral ve iç rotasyonda olmak üzere iki kez yapıldı ve görüntülerin 3 boyutlu rekonstrüksiyonları oluşturuldu. Bu iki bilgisayarlı tomografi tetkikinin 3 boyutlu bilgisayarlı tomografi görüntülerinde korakohumeral aralık ve akromiyohumeral aralık ölçümleri yapıldı. Bulgular: Çalışmaya yaş ortalamaları 64.06±9.06 olan 17 hasta dahil edildi. Tam kat supraspinatus yırtığı olanlarla olmayanlar değerlendirildiğinde, korakohumeral aralık ve akromiyohumeral aralığın omzun nötral ve iç rotasyonundaki ölçümlerinin ortalamaları arasında istatistiksel olarak anlamlı fark görülmedi. Kadın ve erkekler arasında ölçüm ortalaması arasında istatistiksel fark yoktu.Sonuç: Omzun pasif iç rotasyonu ile korakohumeral aralık anlamlı derecede daralmaktadır. Üç boyutlu bilgisayarlı tomografi ile yapılan ölçümler korakoid anatomisi ve korakoidin çeşitli parametreleri ile ilgili bize daha güvenilir bilgi verebilirler.

Evaluation of the effect of internal rotation of the shoulder on the coracohumeral and acromial range with three-dimensional tomography

Purpose: The aim of this study was to assess whether the coracohumeral and acromiohumeral distances were really decreasing with the passive internal rotation of the shoulder. Materials and Methods: The patients who underwent computerized tomography arthrography with the prediagnosis of rotator cuff tear between May 2016 and October 2016 were enrolled in the study. The computerized tomography arthrography imagings were performed in two positions of the shoulder, the neutral position and the internal rotation of the arm, and then the 3 dimensional reconstructions of the images were constituted. The coracohumeral and acromiohumeral distance measurements were made on 3 dimensional reconstructions of these two computerized tomography examinations.Results: Seventeen patients with the mean age of 64.06±9.06 were involved in the study. The coracohumeral and acromiohumeral distance measurements in neutral and internally rotated arms were also statistically similar between patients with full-thickness rotator cuff tears and those without. Between the male and female patients, there was no statistically significant difference in any of measurements. Conclusion: The coraohumeral distance narrows significantly with the internal rotation of the arm. The measurements made on three dimensional computerized tomography may provide us more reliable data about the several parameters of the coracoid process.
