Related to ischial tuberosity: ischial bursitis

is·chi·al tu·ber·os·i·ty

[TA]
the rough bony projection at the junction of the lower end of the body of the ischium and its ramus; this is a weight-bearing point in the sitting position; provides attachment for the sacrotuberous ligament and is the site of origin of the hamstring muscles.

ischial tuberosity

Etymology: Gk, ischion, hip joint; L, tuber, swelling
a rounded protuberance of the lower part of the ischium. It forms a bony area on which the human body rests when in a sitting position.

is·chi·al tu·ber·os·i·ty

(is'kē-ăl tū'bĕr-os'i-tē) [TA]
Landmark at the inferior aspect of the ischium: origin of the hamstring muscles.

tuberosity

an elevation or protuberance.

deltoid tuberosity
a prominence on the lateral aspect of the humerus; the point of attachment of the deltoid muscle.
facial tuberosity
a discrete elevation on the maxilla of cows which serves as an attachment for the rostral part of the masseter muscle.
ischial tuberosity
the pin bone; the most caudal process of the ischium.
olecranon tuberosity
the free end of the ulna; point of attachment of the triceps brachii muscle.
radial tuberosity
a rough patch on the cranial aspect of the proximal end of the radius.
tibial tuberosity
prominent tuberosity protruding from the cranial aspect of the proximal end of the tibia onto which the patellar ligament inserts.

Maximal pain is usually distal to the ischial tuberosity.
With more severe injuries, a plain radiograph of the pelvis should be done to rule out ischial tuberosity avulsion.
When discussing proximal hamstring injuries, one must also consider apophyseal avulsions of the ischial tuberosity.
Similarly, using the ischial tuberosity as a pelvic reference decreases variability of the lateral acetabular component position measurement due to differences in pelvic tilt, which can vary temporally with changes in patient flexibility and position on the X-ray table.
Similar to what is commonly done with the inter-teardrop line on AP films, the long axis of the ischial tuberosity can be used as a skeletal landmark on a true lateral radiograph.
s study, which did not include containment of the ischial tuberosity within the posterior medial border of the prosthetic socket, improved adduction would have still been recorded.
These images show a progressive narrowing of the ML aspect of the socket, which was the penultimate evolutionary step to the ischial tuberosity being captured inside the borders of the socket and providing the definition for a new limb/socket category.

Consequently, the ischial tuberosity (IT) is the most vulnerable site for PUs in people with SCI who use wheelchairs.
