Abstract:

 Objective    The purpose of the study is to describe the precise anatomical  characteristics of the Bassett's ligament, and to explore the physiological function and the clinical significance.    Methods    The study was performed on 10 ankle joints of frozen-fresh cadaveric ankles. The precise location of origin,insertion points, and topogeography were carefully observed，and the precise anatomical parameters（their length, width and thickness）were also recorded.    Result    The Bassett's ligament was present in 8 of 10 ankles, and ran obliquely from anterior tibial tubercles to anterior peroneal tubercles. The shape was quardrangular. Its orientation was parallel and distal to the anterior tibiofibular ligament, its length ranged from 17.86 to 18.56 mm, its width from 3.22 to 3.89 mm，and its thickness from 0.67 to 1.47 mm.  Conclusions   The Bassett's ligament reflects a normal anatomical finding, and the cause of tibiotalar impingement syndrome can be explored by investigating the simulated mechanism of injury of the ligament.
