This bony protrusion bears the weight of the trunk when we sit and is the attachment site for hamstring muscles.
The posterior aspect of the body, along with its muscles, tendons, bones and attachments, is easy to overlook because it’s out of sight and, therefore, often out of mind. Until, that is, pain occurs. The ischial tuberosity—also known as the “sit bones” or even “sitz bones” (from the German word sitzen) (Garikiparithi 2017)—has many different connections, although it is mainly associated with the hamstring muscles (Drake et al. 2010).
