This orientation resulted in distraction and shear forces between the hamstring insertions and ischial
In order to measure the forces generated in the area of the ischial
tuberosities, we employed FlexiForce[R] (Tekscan Inc.
distance between the adductor longus tendon near its origin and the ischial
tuberosity in sitting), and iliofemoral angle (i.
Plain radiographs are often negative but may reveal sclerosis or cystic changes within the lesser trochanter or ischium, decreased femoral offset, or bony prominences from ischial
avulsion injury or multiple hereditary exostoses.
Only two fragments of the left pubis are preserved, comprising almost all the prepubic process, the iliac peduncle and acetabulum, whereas the postpubis and ischial
peduncle are lost by breakage (Fig.
A 27-year-old professional male classical dancer with left ischial
apophysitis volunteered to participate in the study.
Ultrasound (US) examination showed a well-circumscribed, heterogenously hypoechoic, solid nodule in the subcutaneous tissues, inferior to the ischial
tuberosity, adjacent to the common hamstring origin (Fig.

Asymmetrical buttock pressure distribution and the absence of sensation may result in ischial
Most PIs (36 per cent) were located in the pelvic region (sacrum and ischial
Those two bones have a width called the ischial
They all run in similar paths, all originating from the bottom of your pelvis (or Ischial
Tuberosity), running down the back of your leg with the Semimembranosis and Semitendinosis attaching on the inside of your knee and the Biceps Femoris to the outside of your knee.
