the anatomy of the suprascapular notch and its relationship to scapular dimensions are critical in the management of suprascapular neuropathies. Individuals show considerable differences in the dimensions of the suprascapular notch across populations. The purpose of this study was to determine the morphology and morphometric dimensions of the suprascapular notch in adult Malawian cadavers and to suggest clinical implications associated with complete ossification of the suprascapular ligament.
adult dry scapulae from undetermined sex specimens (n=125) obtained from the skeletal collection at Kamuzu University of Health Sciences were classified according to the Rengachary categorization method to assess the suprascapular notch superior transverse distance, mid transverse distance, depth, scapula length and width using a standard Vernier caliper.
the most prevalent suprascapular notch class was type I, which was found in 46 (36.8%) of all scapulae. Type VI was the least common, found in only 1 (0.8%) of the scapulae. The mean notch superior transverse distance was 1.3 ± 0.6 cm, while the mean maximum depth was 0.6 ± 0.3 cm. Only the differences in depth, however, were statistically significant (p=0.001).
the current study has described the morphology and morphometry of the suprascapular notch in relation to the risk of suprascapular nerve entrapment associated with complete ossification of the suprascapular ligament. Our sample population generally showed smaller suprascapular notch and scapular dimensions than other populations. This should be considered during the management of suprascapular neuropathy and preoperative planning of surgical operations of the shoulder region.
肩胛上切迹的解剖结构及其与肩胛尺寸的关系对肩胛上神经病变的治疗至关重要。个体之间肩胛上切迹的尺寸存在显著差异。本研究旨在确定马拉维成人尸体肩胛上切迹的形态和形态学尺寸，并提出与肩胛上韧带完全骨化相关的临床意义。
从卡姆祖大学健康科学学院骨骼收藏中获得的未确定性别的成人干肩胛骨（n=125），根据 Rengachary 分类方法进行分类，使用标准游标卡尺评估肩胛上切迹的上横向距离、中横向距离、深度、肩胛骨长度和宽度。
最常见的肩胛上切迹类型是 I 型，在所有肩胛骨中占 46 个（36.8%）。VI 型最不常见，仅在 1 个（0.8%）肩胛骨中发现。切迹上横向距离的平均值为 1.3 ± 0.6cm，而最大深度的平均值为 0.6 ± 0.3cm。仅深度存在统计学差异（p=0.001）。
本研究描述了与肩胛上韧带完全骨化相关的肩胛上切迹形态和形态学特征，以及肩胛上神经受压的风险。我们的样本人群总体上显示出较小的肩胛上切迹和肩胛骨尺寸，与其他人群相比。在肩胛上神经病的治疗和肩部手术的术前规划中应考虑到这一点。
