“…The forelock sign was positive in two of them. The nodular formation was first described by Wani et al [9] as the healing with nodular scar tissue of a partially torn subscapularis tendon. Subsequently in 2016, Saremi described the air bag sign which was posteriorly bulging of the partially torn subscapularis tendon and added that this lesion was only seen in interstitial tears and in the internally rotated arms during the arthroscopy.…”

“…Long head of biceps tendon pathologies were classified as healthy, tendinopathic (tendinitis or degenerated), dislocated, both dislocated and tendinopathic, and ruptured, as described previously. [15] The subscapularis tears were also scrutinized in terms of intratendinous nodules which was first described by Wani et al [9] in 2013 as nodules ( Figure 3) arising from the intra-articular surface of a partially torn subscapularis tendon.…”

“…Other than this, Sahu et al [8] reported an arthroscopic finding, named sentinel sign with a high inter-and intraobserver reliance which indicates scuffing, abrasion, or tear of the anterior part of the long head of biceps tendon (LHBT) that may show a subscapularis tendon rupture apparent or hidden on arthroscopy. Similarly, Wani et al [9] and Saremi [10] reported the nodular scarring of a partially torn subscapularis tendon as an arthroscopic finding, which is named as air bag sign by Saremi. These efforts to reveal the hidden lesions of the subscapularis tears provided some advance in recognition of these lesions and drove scientists forward to make new investigations and find new viewpoints.…”

ÖZAmaç: Bu çalışmada, subskapularis parsiyel yırtıklarının kakül işareti tanımlandı ve bu işaret ile hava yastığı işaretinin insidansları karşılaştırıldı. Hastalar ve yöntemler: Ocak 2013-Ocak 2016 tarihleri arasında omuz artroskopisi uygulanan hastalar arasından izole subskapularis yırtığı veya izole supraspinatus yırtığı tanısı konulan 120 hasta (39 erkek, 81 kadın; ort. yaş 51.3 yıl; dağılım, 25-79 yıl) subskapularis yırtığı (grup 1), tam kat supraspinatus yırtığı (grup 2), bursal yüz supraspinatus yırtığı (grup 3) ve eklem yüzü supraspinatus yırtığı (grup 4) grubu olmak üzere 30'ar hastalık dört gruba ayrıldı. Tüm hastaların ameliyatının video kaydı vardı. Biseps tendonunun uzun başı (BTUB)'nın bütünlüğü, subskapularis yırtığının Lafosse sınıflandırması ve kakül ve hava yastığı işaretlerinin insidansı değerlendirildi. Bulgular: Grup 1'de hava yastığı işaretinin insidansı %10, kakül işaretininki %60 idi. Kakül işareti grup 1'de diğer gruplardan (olasılık oranı %95 güven aralığında 10.46: 3.9-27.8) ve hava yastığı işaretinden anlamlı olarak daha sıktı (p<0.001). Biseps tendonunun uzun başı bu grupta çoğunlukla patolojikti ve bu da istatistiksel olarak anlamlıydı (p<0.01). Grup 1'de kakül işareti insidansı her BTUB patolojisinde ve Lafosse alt gruplarında benzerdi. Sonuç: Bu çalışmada tanımlanan kakül işareti parsiyel subskapularis tendonu yırtıklarında güçlü gözlemciler arası ve gözlemciler içi tutarlılıkla anlamlı olarak sık (%60) iken hava yastığı işareti nadirdi (%10). BTUB'nin bozuklukları subskapularis yırtıklarıyla güçlü bir şekilde ilişkiliydi fakat kakül işareti BTUB'nin durumunun veya Lafosse sınıflandırmasına göre parsiyel subskapularis tendon yırtığı tipinin bir göstergesi değildi. ABSTRACTObjectives: This study aims to identify the forelock sign of partial tears of the subscapularis and to compare the incidences of this sign and air bag sign. Patients and methods: One hundred and twenty patients (39 males, 81 females; mean age 51.3 years; range, 25 to 79) diagnosed as isolated subscapularis tear or isolated supraspinatus tear from among patients who underwent shoulder arthroscopy between January 2013 and January 2016 were divided into four groups of 30 patients each as the subscapularis tear (group 1), fullthickness supraspinatus tear (group 2), bursal-side supraspinatus tear (group 3), and articular-side supraspinatus tear (group 4) groups. All patients had video records of their operation. The integrity of the long head of biceps tendon (LHBT), Lafosse classification of the subscapularis tear, and the incidence of the forelock and air bag signs were evaluated. Results: The incidence of the air bag sign in group 1 was 10% and that of the forelock sign was 60%. The forelock sign was significantly more frequent in group 1 than in the other groups (odds ratio 10.46: 3.9-27.8 with 95% confidence interval) and the air bag sign (p<0.001). The LHBT was mostly pathologic in this group, which was also statistically significant (p<0.01). The incidence of the forelock sign in group 1 was similar in each LHBT ...
