Malleolus is a medical term referring to the bony protuberances located on either side of the ankle joint. The spelling of this word can be deciphered using the International Phonetic Alphabet (IPA) which is a standardized system for phonetically transcribing sounds in language. According to IPA, the spelling of malleolus is [məˈliːələs], where the double "l" is pronounced as a prolonged "l" sound and the final "us" is pronounced as "uhs". This orthographic representation aids in accurate pronunciation of complex medical terminology for health professionals and laypeople alike.
Malleolus refers to the bony protrusions found on either side of the ankle joint. The term derives from the Latin word "malleus," meaning "hammer," due to the hammer-like shape of these structures. There are two types of malleoli: the lateral malleolus and the medial malleolus.
The lateral malleolus is located on the outer side of the lower leg and forms part of the fibula bone. It presents as a bony prominence just above the ankle joint and provides stability to the joint during movement. The lateral malleolus acts as an attachment point for various ligaments and tendons that support ankle functioning.
On the inner side of the lower leg, the medial malleolus can be found. It is a bony bump formed by the tibia bone and is positioned below the knee and above the ankle joint. The medial malleolus also aids in maintaining joint stability and acts as an attachment site for ligaments and tendons involved in ankle movement.
Together, the lateral and medial malleoli play a crucial role in protecting the bones of the ankle joint and providing strength and support during weight-bearing activities. They also contribute to the overall articulation and mobility of the ankle.
Understanding the anatomy and structure of the malleoli is essential in diagnosing and treating ankle injuries, as these bony prominences are susceptible to fractures or other damages that may affect ankle stability and function.

The word "malleolus" comes from Latin. It is a diminutive form of the word "malleus", which means "hammer". In Latin, "malleolus" specifically refers to a small hammer or a little mallet. The term was later adopted in anatomy to describe the bony protuberances on the inner and outer sides of the ankle joint that resemble small hammers or mallets.
