“… 30 Hook type acromion is the most associated anatomic variation with tear and narrowing of the subacromial region is accused of the mechanism. 28 , 31 The narrowing in the subacromial region can be determined by direct or indirect measurement methods. Indirect methods include acromion anterior slope (AAS), lateral acromial angle (LAA), acromion index (AI), acromio-glenoid angle (AGA) and critical shoulder angle (CSA).…”

ObjectiveThe aim of this study was to evaluate the effect of the rotator cuff tear repair on subacromial space volume.MethodsWe retrospectively identified 21 eligible patients (5 males and 16 females; mean age: 56.4 (range; 46–71) years) who had shoulder arthroscopy for unilateral full-thickness small to medium rotator cuff tear and normal controlateral shoulder joint. The mean follow-up time was 16.1 (range; 12–25) months. Preoperative and postoperative 1 year bilateral shoulder MRIs and Constant scores were reviewed. Subacromial volume was calculated by using Osirix software. Pre-, postoperative and healthy side (contralateral control group) subacromial volumes were recorded. Paired sample and t-tests were used to compare the pre- and postoperative groups. Independent sample t-tests were used to compare the healthy and pre- and postoperative groups. The correlation between the changes in the subacromial volume and the shoulder Constant score were analyzed using Pearson correlation analyses.ResultsThe mean subacromial volume of the preoperative group was 2.95 cm3 (range; 1.53–4.23) and the postoperative group was 3.59 cm3 (range; 2.12–4.84). The volume increase was statistically significant (p < 0.05). The mean subacromial volume of the control group was 3.93 cm3 (range; 2.77–5.03), and the difference between the preoperative group and the control group was statistically significant. There was no significant difference found between the postoperative group and the control group (p = 0.156). There was no significant correlation found between the volume and the constant score changes (r = 0.170, p = 0.515).ConclusionThe subacromial space volume significantly decreases in full-thickness rotator cuff tears smaller than 3 cm and the surgical repair increases the subacromial volume significantly.Level of evidenceLevel IV; Diagnostic Study.

Subacromial impingement syndrome (SIS) is defined as pressurization and impingement between the acromion, the bursa under the acromion, and the rotator cuff during the abduction and elevation of the shoulder joint, resulting in pain and a functional disturbance of elevation. It is the most common disorder of the shoulder, accounting for 44-65% of all complaints of shoulder pain during a physician’s office visit. The study was performed with the aim of valuing the magnetic resonance imaging (MRI) and computed tomography (CT) in diagnosing patients with SIS. A total of 68 patients with SIS were selected as study subjects and subjected to MRI and CT examinations. The diagnostic accuracy and sensitivity of MRI and CT were, respectively, 97.06 and 70.59% ( P < 0.05 ); the detection rates of SIS grade I, grade II, and grade III by MRI were 91.67%, 96.77%, and 100%, respectively, which were significantly higher than 50%, 80.65%, and 68% by CT, respectively ( P < 0.05 ). MRI and CT detection indicated that there was no significant difference in extensive rotator cuff tear, acromion stenosis, and normal acromion detected by MRI and CT ( P > 0.05 ). In conclusion, the diagnostic accuracy, sensitivity, and detection rate of acromion of MRI were higher compared with those of CT examination, and MRI is more suitable in the clinical diagnosis of SIS.

Çalışmamızdaki amacımız, omuz sıkışmasında etkili olduğunu düşündüğümüz korakoid morfolojisini ve korakohumeral mesafeyi ortaya koymaktır. Gereç ve Yöntem: Her iki omuzda korakoglenoidal aralık tipi, korakoid açılanması ve korakohumeral mesafeler ölçüldü. Olguların yaş, cinsiyet, taraf, boy uzunluğu ve el dominansı ile elde edilen sonuçlar arasındaki korelasyonlar değerlendirildi. Bulgular: Her iki omuz korakohumeral mesafe değerleri erkeklerde kadınlardan daha yüksek bulundu (p<0,05). Yaş ile korakoid açılanma ve korakohumeral mesafe değerleri arasında negatif korelasyon tespit edildi (p<0,05). Olguların boy uzunluklarıyla korakohumeral mesafe değerleri arasında pozitif korelasyon görüldü (p<0,05). Her iki cinsiyette açılanma değerleriyle korakohumeral mesafe değerleri arasında herhangi bir korelasyon tespit edilmedi. Sonuç: Çalışmamız, korakoid açılanması ve korakohumeral mesafe değerlerini ortaya koymanın yanısıra, el dominansı ve korakoid açılanmanın korakohumeral mesafe üzerinde etkisi olmadığını göstermiştir.
