Abstract:

Objective   To observe the anatomical structures of the medial ankle ligament, and provide anatomical basis for the clinical minimally invasive repair of the medial ankle ligament.  Methods  Morphological observation of the medial ankle ligament through peeling and dissecting 8 cases of adult male corpses without pathological changes was made, and  relevant data were collected and statistical analysis was made.  Results   The deltoid ligament has superficial and deep layers with up to 6 different bands. From anterior to posterior, the superficial layer consisted of the following: tibionavicular ligament (length 18.22~26.14 mm), the tibiospring ligament (length 6.24~10.40 mm), tibiocalneal ligament (length 10.32~14.36 mm) and superficial posterior tibiotalar ligament (length 8.32~13.52 mm). While the deep layer consisted of the anterior tibiotalar ligament (length 11.32~15.62 mm) and the deep posterior tibiotalar ligament (length 10.22~12.60 mm, width 6.72~9.84 mm, thickness 1.72~2.24 mm).   Conclusions   It is helpful to distinguish the components and bundles according to the shape of the medial ankle ligament. Profound knowledge of the anatomical characteristic of the medial ligament can facilitate a good planning of surgical program.
