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 ischium (/ ˈ ɪ s k i. ə m /; [1] pl.: ischia) forms the lower and back region of the hip bone (os coxae). Situated below the ilium and behind the pubis, it is one of three regions whose fusion creates the coxal bone. The superior portion of this region forms approximately one-third of the acetabulum.

Pain while sitting is a well known symptom when having ischial tuberosity [12] pain, myofascial pain syndrome, coccyx pain , failed back surgery, arachnoiditis, sciatica, piriformis syndrome, and back pain in general. An inability to sit is one of the signs of chronic low back pain. [13]
This includes any break of the sacrum, hip bones (ischium, pubis, ilium), or tailbone. [1] Symptoms include pain, particularly with movement. [1] Complications may include internal bleeding, injury to the bladder, or vaginal trauma. [2] [3] Common causes include falls, motor vehicle collisions, a vehicle hitting a pedestrian, or a direct crush ...
Similar calcification and ossification may be seen at peripheral entheseal sites, including the shoulder, iliac crest, ischial tuberosity, trochanters of the hip, tibial tuberosities, patellae, and bones of the hands and/or feet. [6] DISH can be a complicating factor when suffering from trauma involving the spine.
