The correct spelling of "tuberositas femoris interna" can be a bit tricky, but with the help of IPA phonetics, it becomes clearer. The first word, "tuberositas", is pronounced tu-ber-o-SEE-tus. The second word, "femoris", is pronounced FEE-mor-is. Lastly, "interna" is pronounced in-TER-nuh. The word refers to a bony protrusion in the inner part of the thigh bone.

Tuberositas femoris interna refers to the internal tuberosity of the femur bone, which is a bony prominence or elevation located on the inner side of the upper end of the femur. More specifically, the tuberositas femoris interna is the medial aspect of the intertrochanteric line, a ridge running along the posterior surface of the femur bone.
The tuberositas femoris interna serves as an important attachment site for various muscles and ligaments within the hip region. The most notable structure that attaches to this bony prominence is the iliopsoas muscle, a powerful flexor muscle of the hip joint. Additionally, other hip muscles such as the pectineus and the adductor longus muscles may also attach to the tuberositas femoris interna.
This bony prominence plays a crucial role in maintaining stability and providing support to the hip joint during movements such as walking, running, and jumping. Its size and shape can vary slightly among individuals, but it generally serves as a reference point for assessing hip morphology or for surgical procedures involving the hip joint.
Overall, the tuberositas femoris interna is an anatomical feature of the femur bone that functions as an attachment site for important muscles and ligaments involved in hip movement and stability.
Internal tuberosity of the femur, epicondylus medialis, a projection on the outer surface of the internal condyle of the femur, giving attachment to the internal lateral ligament of the knee-joint and the gastrocnemius muscle.
