Orthofix SambaScrew®

OPTIMAL Pain & Regenerative Medicine is now offering a new sacroiliac joint pain treatment called the Orthofix SambaScrew® to patients in Dallas, Fort Worth and Arlington, Texas.

What is the Sacroiliac Joint?

The sacroiliac joint, commonly known as the SI joint, is located near the bottom of the lumbar spine above the tailbone. This joint connects the sacrum, the triangular bone at the base of the spine, with the pelvis. The SI joint is different from other joints in the body, because it has limited range of motion. This joint helps support the weight of your upper body, which places a large amount of stress across the SI joint.

What is SI Joint Pain?

SI joint pain can be felt on the affected side in the lower back and buttock. In some cases, pain and/or numbness can radiate down into the leg. According to research, SI joint pain is likely the source of pain for 30% of patients who report having lower back pain. Patients with SI joint pain often report disrupted sleep and sitting patterns due to pain and discomfort. The cause of SI joint pain can be due to hypermobility or instability in the joint, or hypomobility or fixation in the joint.

How to Diagnose Sacroiliac Joint Disorder?

Sacroiliac joint disorder is diagnosed by the patient’s history, physical findings, radiological findings, and SI joint injections. SI joint injections, which are the gold standard for confirming sacroiliac joint disorder, are administered with fluoroscopic or CT guidance to validate accurate placement of the needle in the SI joint. Once the needle is inserted into the SI joint, numbing medication is then injected into the joint. Once this is complete, patients are asked to try and reproduce the pain by performing normally painful activities. If the patient experiences 75-80% lower back pain relief during the duration of the anesthetic, a diagnosis of SI joint disorder can be confirmed.

Sacroiliac Joint Pain Treatment

When conservative measures fail to provide lower back pain relief due to SI joint pain, the Orthofix SambaScrew® may be recommended. The SambaScrew utilizes minimally invasive surgical technique as a sacroiliac joint pain treatment. The SambaScrew fixation system works to promote fusion of the SI joint by inserting titanium screws across the joint. These titanium implants are intended to stabilize the joint and have openings that are designed to promote arthrodesis, which is joint ossification between two bones, across the SI joint.


Sacroiliac Joint Pain Treatment Recovery

Following the Orthofix SambaScrew® procedure, patients should will follow the post-operative guidelines provided by the physicians at OPTIMAL.  There will be a small 2-3 inch incision in the lateral buttock area that would be closed with sutures and or staples and this would need to heal for approximately 3 weeks before normal activity can be resumed.  During that time of healing, there would be restrictions on activity and you would not be able to lift more than 10 lbs.  After the incision is completely healed, activity can be increased, but will still be limited some for the first 3 months until the fusion is solid.
