Gluteal pain was reproduced with palpation of the sacrotuberous
ligaments bilaterally, and digital pressure over the L4 and L5 vertebral segments during prone examination.
The boundaries of the perineum are the pelvic floor superiorly, pubic symphysis anteriorly, coccyx posteriorly, ischial tuberosities laterally, ischiopubic rami anterolaterally, sacrotuberous
ligaments posterolaterally, and fascia and skin inferiorly.
1) Pudendal nerve can be compressed when it passes between sacrotuberous
and sacrospinous ligaments or within the Alcock canal.
One patient was found preoperatively to have sacrotuberous
ligament involvement, and another had total sacral involvement.
With a similar mechanism to APC-1 injuries, APC-2 injuries lie farther along the spectrum of soft tissue injury, with disruption of the anterior SI ligaments as well as the sacrotuberous
and sacrospinous ligaments.
Ligaments of the pelvis are sacrospinous, sacrotuberous
, and anterior longitudinal ligament of the sacrum and they contribute to the stability of the bony pelvis.
A recently described alternative open technique consists of a transgluteal approach, which allows access to the pudendal nerve between the sacrospinous and the sacrotuberous
The iliolumbar ligament is one of three vertebral-pelvic ligaments responsible for stabilizing the lumbrosacral spine in the pelvis, along with the sacrospinous and sacrotuberous
Transposition of the sacrotuberous
ligament for the treatment of coxofemoral luxation in dogs.
These injuries are rotationally unstable, there may also be some vertical displacement but this is limited by the sacrotuberous
and sacrospinous ligaments, which typically remain intact (1,2).
The nerve runs between the sacrospinous and sacrotuberous
ligaments, for instance, and entrapment between these two ligaments is probably the most common cause of pudendal neuralgia.
The long and short posterior sacroiliac ligaments, the interosseous ligaments within the sacroiliac joints and the sacrotuberous
ligaments all resist forces leading to vertical translation between the ilia and the sacrum.
