A re-appraisal of the palpation, manipulation and role of sacroiliac joints

The information contained in the following videos represents a fundamental paradigm shift in osteopathy and a significantly more effective way of treating lower back pain and pelvic pain than existing methods. This shift does not involve any major deviation from the principles of structural osteopathy. However 3 very important points need to be made:


  1. 1. Osteopaths and other manipulators have only been palpating half the sacroiliac joint. This recently discovered part of the sacroiliac joint plays a very important role in pelvic pain and lower back pain.

  2. 2. Standard osteopathic techniques do not cavitate the sacroiliac joint sufficiently to clear the restriction in the sacroiliac joint and hence do not produce clinically significant results.

  3. 3. A large proportion of lower back pain is secondary to structural problems in the sacroiliac joints and hence the pelvis as a whole. In this sense lumbar manipulation may produce temporary symptomatic relief but because the sacroiliac joints are not being manipulated properly, long term results are not being achieved.

anatomy, biomechanics, pathophysiology, physical assessment and treatment.

Traditionally the palpatory area of the sacroiliac joint is assumed to lie directly posterior to the joint. The most inferior aspect of the joint lies relatively close to the surface....

If we accept the existence of these new loci, it is logical to look for the anatomical basis for these findings....


The phrase “biomechanics of the pelvis” sounds somewhat antiquated as we are much more used to talking about the biomechanics of the sacroiliac joint...

Although assessing the pelvis as a whole is not going to change the treatment approach, attaining a level and balanced pelvis (at least sitting) after treatment and ideally between treatments is an of ....

There are many physical orthopaedic sacroiliac joint tests. Individually they are not very accurate. Studies would indicate a battery of tests is more accurate...

With the patient supine the practitioner contacts the patient’s knee and flexes and then adducts the hip to allow their other hand to be placed under the pelvis to palpate the sacroiliac joint. With a...

Fundamental to osteopathy is the concept of Osteopathic Somatic Dysfunction (OSD) or what was traditionally referred to as the Osteopathic lesion....

The McKinnen technique is simple in theory but subtle in execution. As with other techniques it requires good tissue tension sense to be effective....

It would appear that there is a relationship between certain types of impacts and lesion loci.
A course of treatment generally involves working on different lesion loci each treatment session....

It is often assumed that getting a single cavitation from a joint is sufficient to release the restriction of movement within it. However this is not the case in the sacroiliac joint....


There are several HVT techniques for the sacroiliac joint. However it is only really the lumbar roll technique that allows for fine tuning of the relevant vectors for point specific manipulation....

There are of course many causes of back pain, however the majority are non-pathological. Good case history taking, clinical examination and when appropriate imaging and other tests should exclude....
