"Hopefully, the increasing numbers of reports on the treatment for SI joint problems will not misguide surgeons to perform uncontrolled interventions and I wish we do not have to state (following Nachemson) that too many SI joints are damaged by surgeons for undefined pain problems.“ (Reviewer’s comment concerning ‘‘the percutaneous stabilization of the sacroiliac joint with hollow modular anchorage screws: a prospective outcome study’’  Paul F. Heini Eur Spine J (2013) 22:2332)

SIMEG is dedicated to support the education on sacroiliac joint surgery with annual conferences, webinars, literature review and an international case registry.

Great lecture.

Comment by Daisuke Kurosawa |

Thank you to our member Dr. William Cross for the truly excellent talk on TV. I learned a great deal. Also, I appreciate your introducing the SIMEG web site, more people will get to know SIMEG through your great job.

The relation between sacroiliac joint (SIJ), hip joint, and lumbar facet joint is very important as you mentioned. I also experienced several patients with severe SIJ pain, whose were relieved after surgery for femoral acetabular impingement (FAI) first. As you presented, we, surgeons, can perform hip joint injections easily using ultrasound. In addition, we really need to pay attention to concomitant pain generators, including facet joint and lumbar disc as well.
I would like pain clinicians to watch his lecture, which contains important information for them, too.

For us surgeons, his reports of revision cases are also important. I respect all SIJ experts who practice minimally invasive surgery (MIS). I understand that really many patients were recovered well with new developed MIS devices. While recognizing its advantages, we must carefully assess the indications for surgery based on his reports to see which cases require revision surgery.

Excellent lecture, thank you Woodie!

Education and teaching of SIJ pathology and anatomy has often been neglected within the major medical societies. Surgical level indication was mainly referred to traumatologic strategies or to preventing measures when long distance spinal instrumentation was involved (e.g. scoliosis surgery). To avoid post fusion degeneration a common technique is to add a spino-pelvic bridge.

The complexity of neurovascular structures are a challenge during the guide pin placement. Limited options for bone preparation required for solid fusion as well as comorbidities, osteoporosis or other factors might prevent expected bone healing. In these cases revisions will become necessary, which often cannot be done by surgeons who are not familiar with these methods.
