The cotyloid ligament is a crucial ligament that connects the femur to the hip socket. The spelling of the word "cotyloid ligament" can be explained by using IPA phonetic transcription, which would be /kɒtɪlɔɪd ˈlɪɡəmənt/. The first part, "cotyloid", originates from the Greek word "kotylos," meaning cup, and is pronounced with an emphasis on the first syllable, as /kɒtɪlɔɪd/. The second part, "ligament," has stress on the second syllable and is pronounced /ˈlɪɡəmənt/. Overall, the spelling of this word accurately represents its pronunciation.
The cotyloid ligament is a strong, fibrous band found within the hip joint that plays a crucial role in providing stability. It is specifically located within the concave socket of the hip joint, known as the acetabulum, and is responsible for holding the head of the femur (thighbone) securely in place.
This ligament is also referred to as the ligamentum teres or the transverse ligament of the acetabulum due to its shape and location. It is attached to the margins and borders of the acetabulum and forms a complete ring around the head of the femur. The cotyloid ligament consists of dense connective tissue made up of collagen fibers, giving it its strength and flexibility.
The primary function of the cotyloid ligament is to provide stability to the hip joint by preventing excessive movement or dislocation of the femoral head. It acts as a strong restraining ligament that limits the range of motion of the hip joint. Furthermore, it plays a vital role in distributing the forces that are exerted on the hip joint during weight-bearing activities.
Damage or injury to the cotyloid ligament can result in instability of the hip joint, leading to pain, decreased mobility, and potential dislocation. In cases of severe ligamentous tears, surgical intervention may be required to repair or reconstruct the ligament and restore stability to the hip joint.
• Labrum glenoidale of the acetabulum.
• A fibrocartilaginous ring which deepens the cavity of the acetabulum, labrum glenoidale.

The word "cotyloid" originates from the Greek word "kotulē" (κοτύλη), which means "cup" or "socket". The term "ligament" comes from the Latin word "ligamentum", meaning "band" or "tie". Therefore, the etymology of "cotyloid ligament" is rooted in both Greek and Latin, with "cotyloid" describing the specific cup-like shape of the structure, and "ligament" referring to its function as a connective band.
