Biomechanically important articular surfaces in the talocrural joint

Area of Science:

• Anatomy
• Biomechanics
• Orthopedics

Background:

• Medial twisting of the foot is a common condition.
• The anatomical factors contributing to this condition are not fully understood.

Purpose of the Study:

• To investigate the relationship between the utile areas of articular surfaces in the ankle joint and medial foot twisting.
• To identify anatomical variations that may predispose individuals to habitual medial foot twisting.

Main Methods:

• Analysis of adult tibia, fibula, and talus articular faces from anatomical collections.
• Measurement and comparison of joint face areas, altitudes, and angles, including the medial malleolus-tibia angle.

Main Results:

• Significant individual variations were observed in the articular faces of the tibia, fibula, and talus.
• Disproportion in the size and shape of these articular bodies was noted.

Conclusions:

• Anatomical disproportion of the ankle's articular bodies is a likely cause of habitual medial foot twisting.
• Findings contribute to understanding the functional anatomy and clinical pathology of the ankle joint.
