The purpose of this study was to determine which spinal segment most closely corresponds to the level of the inferior angle of the scapula (IAS) using measurements taken on A-P full-spine radiographs.
Fifty sequentially selected radiographs were analyzed independently by two examiners. A straight edge was used to ascertain which spinal levels corresponded with the right and left IASs. For analysis, each spinal level was subdivided into three regions: upper vertebral body, lower vertebral body, and intervertebral space.
he mean spinal level corresponding to the left IAS was midway between the T8-9 interspace and the upper T9 body (range, lower T7 to upper T10). The mean spinal level corresponding to the right IAS was slightly lower, but still within the upper T9 body (range, lower T7 to lower T10). These levels correspond to the T8 spinous process.
There is a considerable amount of variability in where the IASs are located, but most commonly, they correspond to the level of the upper body of T9.
本研究的目的是通过在前后位全脊柱X线片上进行测量，确定哪个脊柱节段与肩胛下角（IAS）的水平最接近。
两名检查者独立分析50张连续选取的X线片。使用直尺确定哪些脊柱水平与左右肩胛下角相对应。为了进行分析，每个脊柱水平被细分为三个区域：椎体上部、椎体下部和椎间隙。
与左侧肩胛下角相对应的平均脊柱水平在T8-9椎间隙和T9椎体上部之间（范围，T7下部至T10上部）。与右侧肩胛下角相对应的平均脊柱水平略低，但仍在T9椎体上部范围内（范围，T7下部至T10下部）。这些水平对应于T8棘突。
肩胛下角的位置存在相当大的变异性，但最常见的是，它们对应于T9椎体上部的水平。
