Capitulum fibulae is a Latin phrase that refers to the head of the fibula bone. The spelling of this word can be broken down phonetically using the International Phonetic Alphabet (IPA). Capitulum is pronounced as /kəˈpɪtjʊləm/, while fibulae is pronounced as /ˈfɪbjʊliː/. The use of IPA provides a standardized method for accurately representing the phonetic sounds of words. Understanding the correct spelling and pronunciation of complex medical terms like capitulum fibulae is essential for healthcare professionals to communicate effectively with one another.
Capitulum fibulae, also known as fibula head, refers to the rounded knob-like structure found at the end of a fibula bone. The fibula is one of the two long bones located in the lower leg, the other being the tibia. The capitulum fibulae is specifically located on the proximal (upper) end of the fibula, forming the lateral aspect of the knee joint.
The capitulum fibulae serves as an important point of articulation and connection, as it helps to form the proximal tibiofibular joint. This joint is the synovial joint that connects the fibula to the tibia, enabling movement and stability between these two bones. It plays a significant role in weight-bearing activities, as it helps to distribute forces evenly across the lower leg.
The capitulum fibulae is shaped like a rounded elevation, similar to a small head or knob. It is covered with articular cartilage, a smooth and shiny tissue that reduces friction and allows for smooth movement within the joint. This cartilage also protects the bone from wear and tear.
Overall, the capitulum fibulae is a crucial anatomical structure that contributes to the stability and movement of the knee joint.
Head or upper extremity of the fibula, which articulates by a facet with the under surface of the external condyle of the tibia.
