The spelling of "sulcus malleolaris" can be a bit tricky due to its Latin origins. The correct pronunciation is "SUL-kus mal-ee-oh-LAIR-iss." The "sulcus" refers to a furrow or groove, while "malleolaris" pertains to the ankle bones. So, "sulcus malleolaris" describes a groove on the ankle bone that allows tendons and ligaments to pass through. While the term may be unfamiliar, understanding its spelling and pronunciation can aid in the accurate diagnosis and treatment of ankle injuries.
Sulcus malleolaris refers to a distinct groove or depression located in the area of the ankle joint, specifically on the lower extremity of the tibia bone. The term is derived from the anatomical subunits it includes: "sulcus," which means a groove or furrow, and "malleolaris," pertaining to the malleolus bones present in the ankle joint.
The sulcus malleolaris can be observed on the medial side (inner part) of the ankle joint, where it is formed between the tibial malleolus (the prominent bony bump present on the inner side of the ankle) and the neighboring articulating bones. This groove serves as a deepened surface for the passage and stabilization of tendons and ligaments associated with the ankle joint.
The sulcus malleolaris plays a crucial role in maintaining the stability and functionality of the ankle joint. It provides a specific pathway for tendons such as the tibialis posterior tendon or the flexor hallucis longus tendon to pass through, enabling their proper movements during ankle dorsiflexion or plantarflexion. Ligaments, including the posterior deltoid ligament, which is responsible for preventing extreme inward rotation of the ankle, also attach in this area.
Understanding the anatomy and characteristics of the sulcus malleolaris is essential for healthcare professionals, such as orthopedic surgeons, podiatrists, or physical therapists, who may assess and treat ankle joint pathologies or injuries.
Malleolar s. or groove, a broad groove on the posterior surface of the internal or medial mallcolus, through which the tendon of the tibialis posterior muscle runs.

The term "sulcus malleolaris" is derived from Latin roots.
The word "sulcus" comes from the Latin word "sulcus", which means "furrow" or "groove". It is often used in anatomy to describe a groove or depression in a bone or an organ.
The term "malleolaris" is derived from the Latin word "malleolus", which refers to the bony prominence on either side of the ankle. The malleolus is formed by the lower ends of the tibia and fibula bones.
Therefore, "sulcus malleolaris" can be translated as the "groove or furrow of the malleolus", specifically referring to the grooves or depressions found on either side of the ankle joint, where the malleoli (ankle bones) articulate with other bones.
