Long Dorsal Sacroiliac Ligament

[trevidoo]

Is it possible to injurt the long dorsal si ligament, so it's no longer possible to locate it during palpation?
I injured my back/si joint 1 1/2 years ago and it has taken over my life. I've been through all sorts of treatments and am now getting desperate. Especially because no health professional is addressing my concerns.
The long dorsal si ligament can be easily palpated on my left side, but on my right side (the side of the injury) cannot be found.
Thanks.

@trevidoo I wouldn't focus too much on whether or not a manual therapist/ sports physician is able to palpate the ligament or not. Firstly, considering anatomical differences/anomalies are commonly identified in symptomatic and asymptomatic patients, one should not focus too much on these anatomical abnormalities. Secondly, one should also consider that the degree of motion possible in the sacroiliac joint is still up for debate. Some recent MRI findings suggest no movement can be objectively visualised. Other researchers report 1-3° of motion in the SIJ. Considering the passive stability due to the congruence of osseous structures and strong ligaments, along with assisted active stability from the cranial fibers of the glut max muscle for instance, more factors and underlying mechanisms should be investigated properly, before considering this ligament as a source of (aspecific) pelvic girdle or low back pain. Thirdly, reporting low back / SI pain for that amount of time suggests a broader prospect of investigation, beyond the scope of nociceptive tissue. Not only should health professionals focus on anatomical structures but also on central/peripheral pain mechanisms, maladaptive pain responses, underlying risk factors and psychosocial variables that might help explain the chronic nature of your symptoms. I hope you'll find relief soon and I wish you good luck in your recovery.
