Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Sacroilliac fusion

Arm Description

Pastient are treated with sacroiliac joint arthrodesis to the sacroiliac joint and symphysis

Outcomes

Primary Outcome Measures

Oswestry Disability Index (ODI)
Oswestry Disability Index is a 10 item questionnaire comprises 10 questions about physical function. Each item has a 0-5 scale and the raw score is multiplied by 2 and the sum is the total score. Zero represents excellent physical function and 100 is more or less bedridden. This is the most used outcome measure in low back pain studies.
Visual Analogue Scale (VAS) 0 to 10
Visual Analogue Scale is a 0 -10 scale. Zero is no pain and 10 is the worst pain you can imagine. In this study the patients were asked to report the morgning and evening pain by this scale.

Secondary Outcome Measures

Healing Measured by CT
Number of participants with healing as measured by CT data. The outcome was radiological healing vs no signs of radiological healing. In order to be classified as healed the CT scans had to show Clear signs of bone bridging across the sacroiliac joint.

5. Study Description

Brief Summary
Pelvic girdle pain (PGP) related to pregnancy is a common reason to sick leave during pregnancy. Low back pain and PGP affects about 50% of women during pregnancy. Most of the women recover, however about 10% of the women still have complaints after birth. Most patients have positive effect from conservative treatment, but unfortunately some do still have much pain despite intensive conservative rehabilitation. Surgery has been tried on these women with various results. Surgical treatment is controversial and there is a lack of documentation. The investigators will operate 20 patients with arthrodesis to the sacroiliac joint and symphysis. Radiostereometric analysis (RSA) will be used to evaluate the joint movement in different part of the process. Hypothesis: Severe pelvic girdle pain is caused by pelvic joint instability in some cases and surgically fixation of the affected joints can help these women to get back to a normal life.

Arm Title
Sacroilliac fusion
Arm Type
Experimental
Arm Description
Pastient are treated with sacroiliac joint arthrodesis to the sacroiliac joint and symphysis
Intervention Type
Procedure
Intervention Name(s)
Arthrodesis to the sacroiliac joint and symphysis
Intervention Description
Standard surgical procedures will be used. When the patient has isolated pain in the symphysis isolated fixation will be performed. A 2x2 cm large bone block will be removed and replaced with spongy bone. For fixation the Matta-plate will be applied. To the sacroiliac joint we use an anterior approach. A 2x1,5 cm large bone block will be removed and replaced with spongy bone from the iliac crest. For joint fixation we either use 2 plates or sacroiliac screws. The same procedure will be used on the other side in the cases with bilateral symptoms. Only one side will be operated at a time. After one year it will be decided if it's necessary to perform contralateral surgery.
