BACKGROUND: The spinoglenoid notch (SGN) is the second most common location for suprascapular nerve (SN) entrapment; however, there are few relative morphological reports on this condition. Hence, the present morphological study mainly explored the anatomical structure and classification of the SGN and the relationship with entrapment of SN. MATERIALS AND METHODS: Four hundred seventy-eight scapulae were analysed thoroughly and systematically in this study. Anatomical structure and classification of the SGN were observed and measured by a three-dimensional (3D) reconstruction of computed tomography (CT). The measurement results were then analysed and recorded. RESULTS: Chinese scapulae were classified into three types at the SGN, and it was found that left scapulae had deeper SGN than right ones. Then, significant differences were also noted between sexes. Men had thicker, wider and deeper SGN than women. Type II (small U, 46.04%) was the most common. Type I (large U) was the widest (15.67±1.43mm) and deepest (13.71±2.39mm) compared with other types. Lastly, no significant differences in the above criteria were found in other measurements. CONCLUSIONS: These morphological measurements of the SGN may help to improve the diagnosis and successful treatment rate of the surgery for the SN entrapment, but the relative clinical trial is necessary to support it.
