Abstract：
Understanding the anatomy of suprascapular area helps the clinicians and surgeons in management of any disability at the shoulder region. This work aimed to clear the different morphological and morphometrical types of suprascapular notch (SSN). Unknown 120 dry human scapulae of both sides and 60 formalin-embalmed cadaveric upper limbs (40 males and 20 females) were used in the present study. Three main morphological forms of SSN were reported: J, U, and V-shaped. J-shaped notch showed the highest incidence followed by U-shaped then V-shaped one. Morphometrically, type (III) notch was the most prevalent in both dry bones and cadavers, while the incidence of type (II) was the lowest form. Also, the measurements of superior transverse diameter, middle transverse diameter and vertical dimension of the different types of the notch showed no side or sex significant difference. The suprascapular foramen with ossified superior transverse scapular ligament (STSL) was seen in 5.8% of dry bones and 10% of cadaveric specimens. Fan and band-shaped ossified transverse scapular ligaments were reported. Absence of SSN was seen in 10.8% of dry bones, 7.5% of male and 10% of female specimens with left side predominance. V-shaped, absence, and ossified STSL were considered as predisposing factors of suprascapular nerve entrapment syndrome. Knowledge of the morphology and morphometric parameters of SSN is of great clinical significance for anatomists, radiologists, physiotherapists, orthopedics and neurosurgeons to perform good diagnosis and best planning for surgical or arthroscopic interventions within the shoulder region.
摘要：
了解肩胛骨上区域的解剖结构有助于临床医生和外科医生管理肩关节区域的任何残疾。这项工作旨在清除肩胛骨上切迹（SSN）的不同形态和形态类型。本研究使用了未知的120例两侧干燥的人类肩胛骨和60例福尔马林防腐的尸体上肢（男性40例，女性20例）。报告了SSN的三种主要形态：J，U,V形。J形缺口发生率最高，其次是U形，然后是V形。形态测量,(III)型切口在干骨和尸体中最普遍，而类型（II）的发病率最低。此外，上横向直径的测量，不同类型切口的中部横向直径和垂直尺寸没有侧面或性别的显着差异。在5.8％的干骨和10％的尸体标本中可以看到带有骨化的上横肩胛骨韧带（STSL）的肩胛骨上孔。报告了扇形和带状骨化的横向肩胛骨韧带。在10.8%的干骨中发现缺乏SSN，男性标本占7.5％，女性标本占10％，左侧占优势。V形,缺席,骨化的STSL被认为是肩胛骨上神经卡压综合征的诱发因素。了解SSN的形态和形态参数对解剖学具有重要的临床意义。放射科医生,物理治疗师,骨科和神经外科医生对肩部区域内的手术或关节镜干预进行良好的诊断和最佳计划。
