Steps for Diagnosing Si Joint Dysfuntion

Step 1: Patient History and Symptoms Assessment

Accurately diagnosing SI joint pain begins with a comprehensive patient history and symptoms assessment. Medical professionals will engage in a detailed conversation with the patient, gathering information about the location, duration, and nature of the pain. Inquiring about any previous injuries, trauma, or conditions that may contribute to SI joint dysfunction is essential. Understanding the patient's symptoms, such as lower back pain, buttock pain, or pain radiating down the legs, helps narrow down the diagnosis and determine the appropriate course of action.

Step 2: Physical Examination

Performing a thorough physical examination is vital to evaluating SI joint pain. During the examination, the doctor will assess the patient's range of motion, looking for any limitations or pain triggers. Provocative tests, such as the Fortin finger test or Gaenslen's test, can help reproduce the patient's symptoms and provide valuable diagnostic information. Palpation of the SI joint area may also reveal tenderness, swelling, or inflammation, indicating potential SI joint involvement.

Step 3: Diagnostic Imaging and Injections

Diagnostic imaging techniques are necessary to confirm SI joint pain. X-rays can help identify structural abnormalities or degenerative changes in the joint. Magnetic Resonance Imaging (MRI) provides a detailed view of the soft tissues, ligaments, and cartilage surrounding the SI joint, allowing for better evaluation of any potential damage or inflammation. Performing diagnostic SI joint injection, guided by fluoroscopy or ultrasound, may be performed to confirm the origin of pain and provide therapeutic benefits simultaneously.

STEP 4: Treatment Options

When diagnosing SI joint pain, it is essential to explore appropriate treatment options to provide patients with optimal relief. While conservative measures such as physical therapy, medication, and injections may be considered, some cases may require more advanced interventions like SI joint fusion with SiFix.

Contraindications for the SiFix procedure include deformities and anatomic variations that prevent or interfere with the SiFix implant system, sacral or iliac bone tumor, active infection at the treatment site, and gross joint instability or dislocation.

FAQ

  • NuFix is a cortical anti-migrational allograft derived from the femur or tibia and is used for the stabilization of the spine.

  • NuFix is positioned between the superior and inferior walls of the facet joint, following the angle of the joint.

  • Stabilization is achieved by a precision press-It accomplished through the difference in the reamed socket and the allografts diameter.

  • The pressure exerted on the facet walls by an interference !t of the allograft. Aggressive anti-migrational fins have been circumferentially machined into the graft to resist motion.

  • • NuFix can be used to provide fixation and additional columns of support as an adjunct to another fusion technique, (e.g. posterolateral fusion or spinous process plating).

    • NuFix can be used posteriorly to complete an anterior/posterior fusion.

    • NuFix can be used for revisions to supplement segment stability after hardware removal or for failed/loosening hardware.

The NuFix System has several significant benefits for long-term pain relief.

  • Provides Stabilization of the Posterior  Spinal Column

  • Cost Effective, Reduces O.R. Time,  and Decreases Hospital Stay Relative  to Fusion Devices

  • Instrumentation Allows for Safe,  Reproducible Implantation 

  • Reduces Tissue and Bone Destruction

  • Textured Surface Provides Graft  Stability and Resistance to Graft  Migration

Steps for Diagnosing Facet Syndrom

Step 1: Patient History and Symptoms Assessment

Accurate diagnosis of facet syndrome begins with a thorough patient history and symptoms assessment. During the initial consultation, healthcare professionals will engage in a detailed conversation with the patient, gathering information about the pain's location, duration, and characteristics. It is important to inquire about any previous injuries, trauma, or conditions that may contribute to facet joint dysfunction. Understanding the patient's symptoms, such as localized back pain, stiffness, or pain exacerbated by certain movements or positions, helps in narrowing down the diagnosis and determining the appropriate course of action.

Step 2: Physical Examination

A comprehensive physical examination is crucial in evaluating facet syndrome. The doctor will assess the patient's range of motion, paying close attention to the spine's flexibility and any signs of pain or discomfort during specific movements. Palpation of the affected area may reveal tenderness or trigger points that correspond to the facet joints. Provocative tests, such as the lumbar extension test or segmental instability test, can help reproduce the patient's symptoms and provide valuable diagnostic information.

Step 3: Diagnostic Imaging and Injections

Diagnostic imaging techniques play a vital role in confirming the diagnosis of facet syndrome. X-rays can help identify structural abnormalities, such as osteoarthritis or degenerative changes, in the facet joints. Magnetic Resonance Imaging (MRI) provides a detailed view of the soft tissues, discs, and facet joints, allowing for better evaluation of any potential inflammation, nerve compression, or spinal stenosis. A diagnostic facet joint injection, guided by fluoroscopy or ultrasound, may be performed to confirm the source of pain and provide temporary relief.

STEP 4: Treatment Options

When diagnosing facet syndrome, it is essential to explore appropriate treatment options to provide patients with optimal relief. While conservative measures such as medication, physical therapy, and injections may be considered, some cases may require more advanced interventions like facet joint fusion with NuFix.

Contraindications for the NuFix procedure include systemic infection or skin infection over the puncture site; bleeding disorders or coagulopathy; allergy to contrast agents or any of the medications to be administered; inability to obtain percutaneous access to the target facet joint; progressive neurological disorder which may be masked by the procedure; and pregnancy.
