SI Joint Injections in Bayonne, NJ

At our Bayonne, NJ, location, Gerling Spine Care and Research Institute offers SI joint injections as a precise, image-guided approach to diagnosing and treating sacroiliac joint pain, one of the most common and most frequently missed sources of chronic lower back, buttock, and leg discomfort.

Lower Back Pain Is Not Always a Spine Problem

A substantial portion of chronic lower back pain has nothing to do with a disc or a nerve. The sacroiliac joint, where the base of the spine meets the pelvis, is responsible for a meaningful share of cases, yet it remains one of the most consistently underdiagnosed pain sources in all of spine care. Its symptoms mimic lumbar disc disease and radiculopathy closely enough that imaging alone cannot reliably distinguish between them. A targeted diagnostic injection can.

At Gerling Spine Care and Research Institute, SI joint injections give our Bayonne patients both a reliable way to confirm whether the SI joint is driving their pain and a direct therapeutic path when it is. Contact our Bayonne office today to find out whether SI joint injections are the right next step for your condition.

What Are SI Joint Injections?

The sacroiliac joint connects the sacrum, the triangular bone at the base of the spine, to the iliac bone of the pelvis on each side. Like any synovial joint, it can become inflamed, degenerated, or destabilized, producing pain that is frequently mistaken for lumbar spine pathology. An SI joint injection delivers a combination of local anesthetic and corticosteroid directly into the joint space. The anesthetic acts quickly, producing short-term relief that tells the clinical team something imaging cannot: whether this particular joint is genuinely responsible for the patient's symptoms. The corticosteroid follows with a slower, more sustained anti-inflammatory effect that can last from several weeks to several months.

Diagnostic Versus Therapeutic Purpose

Like medial branch blocks, SI joint injections serve two distinct but related functions. As a diagnostic tool, the anesthetic component provides a direct test of whether the SI joint is the primary pain source. A significant reduction in symptoms after the injection strongly implicates the joint and gives the care team the clarity needed to direct further treatment with confidence. As a therapeutic intervention, the corticosteroid targets the joint inflammation responsible for the pain, providing relief that supports physical therapy participation and functional recovery. The patient's response to both components shapes the broader treatment plan going forward.

How SI Joint Injections Fit Into a Broader Treatment Plan

For patients with confirmed SI joint pain, injections are typically one part of a broader management strategy that also includes physical therapy aimed at addressing the muscular imbalance and pelvic instability that commonly accompany SI joint dysfunction. When injections confirm the SI joint as the pain source but relief proves temporary, surgical stabilization through SI joint fusion may be discussed as a more definitive, longer-term solution.

We’re here to help you move forward.

Conditions Treated With SI Joint Injections

SI joint injections are appropriate when the sacroiliac joint is identified as a likely contributor to a patient's symptoms. They are used to evaluate and treat:

Sacroiliac joint dysfunction or instability
Sacroiliitis from any underlying cause
Degenerative arthritis of the SI joint
Post-partum SI joint pain and pelvic instability
SI joint stress following lumbar fusion at L5-S1
Ankylosing spondylitis with SI joint involvement
Lower back, buttock, or leg pain of suspected SI joint origin that has not responded to conservative care

Are You a Candidate for SI Joint Injections in Bayonne?

Strong candidates have lower back, buttock, hip, or leg pain that has persisted through conservative care and is suspected on clinical grounds to involve the sacroiliac joint. Characteristic features of SI joint involvement include pain located just below the beltline on one side, symptoms that worsen with prolonged sitting, extended standing, or transitional movements like rising from a chair, and a pattern that does not follow a clear nerve root distribution into the leg.

Injections are generally not appropriate for patients with active infection, bleeding disorders, or relevant medication contraindications. Patients taking blood thinners or certain diabetes medications will receive specific pre-procedure guidance during their consultation. Our Bayonne team will conduct a thorough clinical evaluation and review your imaging before recommending any injection, placing it within the context of your full diagnostic picture rather than as a reflexive next step.

What to Expect From SI Joint Injections in Bayonne

SI joint injections are efficient outpatient procedures with minimal downtime. Most patients complete the appointment within an hour and return to normal activities the following day.

Before Your Procedure

Your consultation will cover your symptoms, imaging, and prior treatment history in detail. Our team will explain the procedure and what both a positive and a negative response mean for your ongoing care. The importance of carefully tracking your pain levels in the hours following the injection will be emphasized, as that information is central to the diagnostic value of the procedure and directly shapes what comes next.

The Day of Your Procedure

You will lie face down on the procedure table while the injection site is cleaned and numbed with a local anesthetic. Under fluoroscopic guidance, a thin needle is advanced precisely into the SI joint. A contrast agent is injected first to confirm correct placement within the joint, and the medication is then delivered. The procedure typically takes less than 30 minutes. Some mild soreness at the injection site for a day or two afterward is normal.

Recovery After Your Procedure

Most patients return to normal activities the day after the injection. The anesthetic component provides prompt relief lasting several hours, and it is normal for some pain to return briefly as it wears off before the corticosteroid begins to take effect, typically within 24 to 72 hours. Relief from the steroid component can last from several weeks to several months. Tracking the degree and timing of relief carefully after the procedure is important, as this information directly informs the next steps in your care plan.

Why Choose Gerling Spine Care and Research Institute?

Persistent lower back pain that has not responded to prior treatment almost always has a specific source that has not yet been accurately identified. The SI joint is one of the most commonly overlooked possibilities, and identifying it requires a team that approaches unresolved lower back pain with genuine diagnostic curiosity rather than a fixed protocol. At Gerling Spine Care and Research Institute, our Bayonne patients benefit from a team that will pursue the right answer systematically and has the full range of treatment options to act on it once found.

SI Joint Injections Frequently Asked Questions

How is an SI joint injection different from an epidural injection?

An epidural injection delivers medication into the epidural space surrounding the spinal cord. It is used for nerve-related pain that radiates into the legs along a defined nerve root pattern. An SI joint injection targets the sacroiliac joint itself. It is used for pain originating in that joint, typically felt in the lower back, buttock, and sometimes the upper leg, but without the clear dermatomal distribution that characterizes nerve root pain.

How do I know if the SI joint is causing my pain?

SI joint pain tends to be felt just below the beltline, is usually one-sided, worsens with prolonged sitting or standing and with transitional movements, and does not radiate clearly below the knee. That said, it can be difficult to distinguish from lumbar spine pathology on clinical presentation alone, which is precisely why a guided diagnostic injection is one of the most reliable tools available for confirming or ruling out the SI joint as the primary source.

How many SI joint injections can I receive per year?

Most clinical guidelines recommend a maximum of three injections per year at a given joint, in consideration of the cumulative effects of repeated corticosteroid use on joint tissue over time. Your care team will determine the appropriate frequency based on your response and overall clinical situation.

What does it mean if the injection doesn't help?

Minimal relief following a diagnostic SI joint injection suggests the SI joint is likely not the primary pain generator, which is itself valuable information; it redirects the diagnostic focus toward other structures. If injections confirm the SI joint as the source but do not produce adequate or lasting relief, surgical stabilization through SI joint fusion may be discussed as the next step.

Can SI joint pain come back after injections?

Yes. Injections address the inflammatory component of SI joint pain but do not resolve the underlying structural dysfunction responsible for it. For patients with recurring or persistent SI joint symptoms, a longer-term management strategy incorporating physical therapy, activity modification, and, in appropriate cases, surgical stabilization will be developed as part of ongoing care.
