Relationship between attachment site of tibialis anterior muscle and shape of tibia: anatomical study of cadavers.

Background: Tibialis anterior (TA) muscle is the largest dorsiflexor of the ankle joint and plays an important role during gait movement. However, descriptions of the TA attachment site are inconsistent even among major anatomy textbooks, and its origin, especially the attachment site for the tibia, has not been reported in detail. This study is the first experimental attempt to investigate the origin of the TA in detail, paying particular attention to the relationship with the shape of the tibia, including sex differences.

Transverse ligament of the elbow joint: an anatomic study of cadavers.

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.
