Which ligament connects the sitting bone to the thighbone and is located at the hip joint?

• A. Anterior Sternoclavicular Ligament
• B. Dorsal Ulnocarpal Ligament
• C. Ischiofemoral Ligament
• D. Proximal Radioulnar Joint

Answer: (C)

The ischiofemoral ligament fits the description because it directly connects the ischium (the sitting bone) to the femur at the hip joint. It originates from the ischial part of the acetabular rim and attaches to the femoral neck, forming a thick posterior reinforcement of the joint capsule. This ligament helps stabilize the hip, especially by limiting internal rotation and excessive extension. The other options are not hip ligaments: one is a ligament of the shoulder joint, another of the wrist, and the last is not a ligament at all but a joint structure, so they don’t describe a connection between the sitting bone and the thighbone.
