The term "spina peronealis" refers to the fibular spine, a small projection found on the fibula bone of the leg. The IPA phonetic transcription of this term is /ˈspɪnə pəroʊniːəlɪs/, which breaks down as follows: "spina" is pronounced with the sound of "sp" followed by "ih" as in "sit", "n" as in "no", and "a" as in "father"; "peronealis" is pronounced with "p" followed by "ih" and then "r" as in "red", "ow" as in "go", "n" and "ih" again, "aa" as in "father", "l" as in "like", "iy" as in "happy", and "s" as in "sit".
Spina peronealis refers to a bony prominence on the lateral aspect of the fibula, a bone located in the lower leg. More specifically, it is a protrusion or ridge that can be found extending along the posterior surface of the fibula shaft. This anatomical feature is also commonly known as the peroneal spine or the peroneal ridge.
The spina peronealis serves as an attachment point for various ligaments and tendons involved in the stabilization and movement of the ankle joint. It provides support to the lateral ankle structures and enhances their functionality during weight-bearing activities such as walking or running.
The prominence of the spina peronealis can vary between individuals, and its size or presence may influence the development of surrounding structures. In some cases, the spina peronealis may cause irritation or friction against adjacent soft tissues, leading to symptoms like pain or discomfort. This condition is known as peroneal spina syndrome or peroneal ligamentous hypertrophy, and it may require conservative treatments or surgical intervention depending on the severity of symptoms.
Understanding the anatomy of the spina peronealis is crucial for healthcare professionals, particularly orthopedic surgeons, radiologists, and physical therapists involved in the assessment and treatment of lower limb injuries. By recognizing the presence and characteristics of the spina peronealis, these healthcare professionals can better diagnose and manage conditions affecting the ankle and fibula region.

The term "spina peronealis" is derived from Latin roots.
- "Spina" in Latin means "spine" or "thorn". In anatomical terms, it refers to a bony prominence or spine-like projection.
- "Peronealis" comes from the Latin word "peroneus", meaning "fibula". The fibula is one of the two long bones in the lower leg.
Combining these two elements, "spina peronealis" refers to a bony projection or spine-like process located on the fibula (peroneus) bone. This term is typically used in medical contexts related to the anatomy of the lower leg.
