Obturator Tubercle Anterior

The anterior obturator tubercle (lat. tuberculum obturatorium anterius, abbreviated pna, bna, jna) is a small elevation of bone tissue on the inner surface of the pelvic bone.

The anterior obturator tubercle is located above the obturator foramen, just below the obturator groove. Separated by the obturator fossa from the posterior obturator tubercle.

The anterior obturator tubercle serves as the site of muscle attachment. The beginning of the obturator muscle and the pubovesical muscle approach it. Sometimes the anterior obturator tubercle is divided into two parts by a groove for the passage of the pubovesical muscle.

Thus, the anterior obturator tubercle is one of the anatomical landmarks of the inner surface of the pelvis and serves as the attachment point for important muscles of the pelvic floor.

The obturator tubercle is posterior and the obturator tubercle is anterior.

The obturator tuberosity is a bony thickening that forms the lower part of the anterior surface of the ischium. The obturator tuberosity of the superior posterior femur is located above the knee joint. The obturator anterior tuberosity overlies the medial portion of the tibia, which is important for maintaining bony articulation for various types of hip movements (eg, knee flexion and hip abduction).

In front of the obturator tuberosity is the deviscular crest, which is a plate in the popliteal region. The devicular crest carries the central cutaneous branch from the supinator nerve. The girl has a certain tendency to traumatic findings when moving the hip in favor of hernia of the obturator muscles, ossification and benign tumors.
