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.
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.
It then spreads along the ischial ramus as the falciform process, whose concave edge blends with the fascial sheath of the internal pudendal vessels and pudendal nerve. The lowest fibres of gluteus maximus are attached to the posterior surface of the ligament; superficial fibres of the lower part of the ligament continue into the tendon of ...
In anatomy, the Nelaton's Line (also known as the Roser-Nélaton line) is a theoretical line, in the moderately flexed hip, drawn from the anterior superior iliac spine to the tuberosity of the ischium. It was named for German surgeon and ophthalmologist Wilhelm Roser and French surgeon Auguste Nélaton.
Tiny osseous fragments near the presumed attachment site of a ligament suggest this diagnosis. Common sites are the lateral tibial plateau (the Segond fracture), the spinal tuberosity of the tibia resulting from anterior cruciate ligament avulsion, and the ischial tuberosity. [1]
The body contains a prominent spine, which serves as the origin for the superior gemellus muscle. The indentation inferior to the spine is the lesser sciatic notch. Continuing down the posterior side, the ischial tuberosity is a thick, rough-surfaced prominence below the lesser sciatic notch. This is the portion that supports weight while ...
pudendal nerve entrapment, ischiofemoral impingement, greater trochanter ischial impingement, and ischial tunnel syndrome. [1] Treatment: Conservative treatments include physical therapy, analgesics, and injections. [2] [4] Surgical treatment is a sciatic nerve decompression and/or muscle resection. [5]
The ischial spine is part of the posterior border of the body of the ischium bone of the pelvis. It is a thin and pointed triangular eminence, more or less elongated ...
