The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.
The ischial bursa is a synovial bursa located between gluteus maximus muscle and ischial tuberosity. [4] When in a seated position, the ischial bursa is put under the highest amount of pressure, which is most significant against a hard surface. [3] Friction from exercise can lead to inflammation of the ischial bursa, known as bursitis. [1]
The ischiopubic ramus is a compound structure consisting of the following two structures: from the pubis, the bones inferior pubic ramus; from the ischium, the inferior ramus of the ischium; It forms the inferior border of the obturator foramen and serves as part of the origin for the obturator internus and externus muscles.
Age. The risk of most causes of joint pain increases with age. This may be due to increased wear and stress on joints over time and a higher likelihood of other underlying medical conditions ...
The superior ramus is a partial origin for the internal obturator and the external obturator muscles.

Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain, difficulty swallowing [5] [6] or even dyspnea. [7] Similar calcification and ossification may be seen at peripheral entheseal sites, including the shoulder, iliac crest , ischial tuberosity , trochanters of the hip, tibial tuberosities ...
