Thirty-two human vertebral columns were selected from the Kanazawa Collection at the University of Kanazawa, Japan. The superior articular joint surface was categorised into the thoracic type and the lumbar type, and the pattern of the change from one type to the other in the lower thoracic and upper lumbar region was examined. In 21 of 32 cases (66%), the change from the thoracic to the lumbar type occurred over 2 vertebral segments, either between the 12th thoracic and 1st lumbar vertebrae (44%) or between the 11th and 12th thoracic vertebrae (22%). In the remaining 11 cases (34%), the change occurred over 3 vertebral segments, with a transitional type of articular surface. The change from the thoracic to lumbar type of articular surface has been believed to occur over 2 vertebral segments, but occurs over 3 segments in as many as 34% of the articular surfaces.
从日本金泽大学的金泽藏品中选取了32个人类脊柱。将上关节面分为胸椎型和腰椎型，并研究了下胸椎和上腰椎区域从一种类型转变为另一种类型的变化模式。在32例中的21例（66%）中，从胸椎型到腰椎型的变化发生在2个椎体节段上，要么在第12胸椎和第1腰椎之间（44%），要么在第11和第12胸椎之间（22%）。在其余11例（34%）中，变化发生在3个椎体节段上，伴有过渡型关节面。关节面从胸椎型到腰椎型的变化一直被认为发生在2个椎体节段上，但在多达34%的关节面中发生在3个节段上。
