Diagnosis of SI Joint Instability and Dysfunction

Taking the correct steps for diagnosis

Before planning the procedure, the sacroiliac joint must be clearly identified as the principal source of pain. Due to mechanical or radicular symptoms, the SI joint can also mimic conditions in the lumbar spine and/or the hip joints. The reverse is also true. Treatment of pathological findings may therefore include the following steps to determine the SI joint is the source of pain and to also determine if LinQ™ is a viable option for treatment.

Identification of SI Joint Dysfunction Risk Factors
Any notable falls, missteps, awkward lifting or twisting of the pelvis over the course of your lifetime
Discussion of previous fusion surgery involving the lumbar spine (lower back) and all treatments to date
Observation of uneven leg length, abnormal walking pattern or scoliosis Past pregnancy (female patients)
New onset of chronic Low Back Pain +/- trauma (possible auto accident) Temporal relationship to post-partum
Iliac crest bone graft
Structural abnormalities, scoliosis, etc…
Inflammatory arthritis
Review of any previous diagnostic imaging (MRI, CT and X-rays)
