背景：肘关节内侧副韧带由前斜韧带(AOL)、后斜韧带(POL)和横韧带(TL)组成。本研究旨在阐明TL的结构，重点研究TL和AOL之间的连续性。方法：2016-2018年间，在爱知医科大学解剖了42具身体，男18具，女24具。排除6例肘关节畸形或萎缩患者，解剖60肘(男15例，女15例)，在体视显微镜下观察TL和AOL的纤维形态。热释光分为两种类型。44肘(73.3%)可见TLS延续至AOL远端(I型)，16肘(26.7%)可持续至整个AOL(II型)。女性肘部II型TLS的发生率显著高于男性(P=0.041)。立体显微镜观察发现，两种类型的TL纤维均垂直于AOL的远端半部进入。结论：TL常持续至AOL的远端，但很少持续至整个AOL。持续到整个AOL的TL在女性的肘部比男性更常见。IL可能通过其与AOL的连续性而促进肘关节内侧的稳定性。(C)2019年，由Elsevier Inc.代表《肩肘外科杂志》董事会出版。
Background: The medial collateral ligament of the elbow joint consists of the anterior oblique ligament (AOL), posterior oblique ligament (POL), and transverse ligament (TL). This study aimed to clarify the structure of the TL, with a focus on the continuity between the TL and AOL.Methods: A total of 42 cadavers (18 males, 24 females) were dissected at Aichi Medical University between 2016 and 2018. Cases of elbow deformity or atrophy were excluded, and 60 elbows (15 males, 15 females) were dissected to assess the fibers of both the TL and AOL using a stereomicroscope.Results: The TL could be detected in all elbows and always continued to the AOL. The TL was classified into 2 types. The TLs continuing to the distal half of the AOL (type I) were observed in 44 elbows (73.3%), whereas the TLs continuing to the entire AOL (type II) were found in 16 elbows (26.7%). Type II TLs were significantly more frequently observed in the elbows of females than in those of males (P = .041). Stereomicroscopic observation revealed that the TL fibers entered perpendicularly to the distal half of the AOL in both types.Conclusions: The TL frequently continues to the distal half of the AOL, but rarely continues to the entire AOL. The TLs continuing to the entire AOL were more frequently detected in the elbows of females than in those of males. The IL possibly contributes to medial elbow stability via its continuity to the AOL. (C) 2019 Published by Elsevier Inc. on behalf of Journal of Shoulder and Elbow Surgery Board of Trustees.
