functions to maintain stability and ensure the proper transfer of force
through the lower limb. The ankle joint connects the leg and the foot to
establish lower limb stability, is an important joint in relation to
movement. The ankle joint is usually stabilized by several structures
and trauma to the ankle joint is very common. So understanding the
anatomy and biomechanics of the ankle is important for choosing
treatment approach and preventing nerve injuries, poor healing or
dysfunction. One structure of interest is the deltoid ligament complex,
also known as the medial stabilizer of the ankle from eversion.
Repeated episodes of ankle sprain can cause laxity of lateral dualligament hence leading to chronic ankle instability. The deltoid
ligament complex consists of the tibiotalar joint whose function
prevents and limits the tilting of the joint. Deltoid ligament complex
has six different parts divided into two layers; one superficial layer
consisting of four bands and one deep layer consisting of two bands.
However, studies have been debating about heterogeneity of the size
and prevalence of the deltoid ligament components. Studying and understanding the anatomy and biomechanics of the deltoid ligament
and its components is very helpful in regards to the guidance of the
anatomical placement of repair or the reconstruction in case of
ligament injury or instability. | Keywords : | | anterior tibiotalar ligaments(ATTL) , deep fibres of the
