(13) Muscle fatigue also contributes to the risk of injury, with hamstring avulsion from the ischial tuberosity
common in dancers and other athletes who place stress on stretched hamstrings.
In this model, greater stresses are appreciated at the points of contact between the ischial tuberosity
and the soft tissue, finding the greatest stresses when the simulated injuries wereoriginated inside the soft tissue.
The studies indicate that despite education, powered wheelchair users do not use the recommended magnitude of tilt or recline required to adequately relieve pressure around the vulnerable ischial tuberosity
From its broad superomedial attachments the fibres of the sacrotuberous ligament converge as they pass downwards, laterally and slightly anteriorly towards the ischial tuberosity
Upon visualization and isolation of the proximal attachments, all other soft tissue was removed from the ischial tuberosity
1= greather trochanter; 2= tendon of piriformis muscle; 3= tendon of obturator internus muscle; 4= ischiatic nerve; 5= obturator internus muscle; 6= ischial tuberosity
; 7= quatratus femoris muscle.
A pilot study on living subjects sought to determine the accuracy with which the Skeletal ML could be predicted using noninvasive measurements typically recorded by prosthetists during their everyday clinical practice, including sex, stature, anterior-posterior dimension (i.e., distance between the adductor longus tendon near its origin and the ischial tuberosity
in sitting), and iliofemoral angle (i.e., soft tissue angle in the coronal plane between the lateral femoral shaft and gluteus medius in standing) .
(5) indicated that an avulsion fracture of the ischial tuberosity
in a 14-year-old patient compressed the sciatic nerve, which was then relieved by surgical excision.
Contact points were the lumbar mamillary processes, sacral apex and ischial tuberosity
. The patient was fitted for a sacroiliac (SI) belt.
The medium-sized curvilinear probe was required to ensure that bony landmarks, ischial tuberosity
and the posterior border of the greater trochanter of the femur, were well defined in the image.
Concurrent whole body bone scan was also completed which provided the evidence of diffuse skeletal metastasis, including skull, left scapula, right sacroiliac joint, and ischial tuberosity
The medial hamstrings consist of two muscles namely semitendinosus and semimembranosus which take origin from ischial tuberosity
and get inserted into medial condyle and upper part of tibia, while the lateral hamstrings which consist of long head and short head of biceps femoris take origin from ischial tuberosity
get inserted into head of fibula.
