#mbbs Inversion and Eversion of Foot Lower Limb Simplified English BDC Anatomy
video summary
The article discusses the anatomical concepts of foot inversion and eversion, which are crucial for understanding movements of the lower limb. Inversion refers to the sole of the foot facing inwards, while eversion involves the sole facing outwards. These movements are essential for balancing on uneven surfaces. Key joints involved are the talocrural, subtalar, and talonavicular joints, which facilitate these actions around an oblique axis. Inversion is typically accompanied by plantar flexion, and eversion is associated with dorsiflexion. The range of movement for inversion is approximately 30 degrees, whereas eversion allows for about 20 degrees. The article also emphasizes that the narrow posterior part of the talus bone increases mobility during plantar flexion, contributing to a higher incidence of inversion injuries compared to eversion injuries. It highlights the role of specific muscles in facilitating these movements and their clinical significance for activities like walking on uneven terrain. Overall, it stresses the importance of understanding these movements in the context of anatomy and injuries related to the lower limb.
