Ultrasound-Guided Injections

What they are

Ultrasound-guided injections are exactly what they sound like: I use a real-time ultrasound image to guide a needle to the precise target structure and deliver medication exactly where it needs to go. No guessing. No blind landmarks. I can see the needle, the target, and the medication spreading in real time.

Why ultrasound guidance matters

Blind injections (guided by anatomical landmarks alone) have a surprisingly high miss rate for many targets. Studies show that landmark-guided shoulder injections miss the subacromial bursa 30 to 40 percent of the time. For the glenohumeral joint, the miss rate can be even higher. Ultrasound guidance brings accuracy to near 100 percent for most targets.

Accuracy matters because the right medication in the right place works. The same medication in the wrong place doesn't.

What we inject

Corticosteroids. A potent anti-inflammatory that's effective for acute joint inflammation, bursitis, and nerve irritation. I use these selectively because repeated steroid injections can weaken soft tissue over time. When they're indicated, though, the relief can be significant and fast.

Hyaluronic acid (viscosupplementation). A gel-like substance that improves lubrication and cushioning inside arthritic joints, particularly the knee. It's a structural treatment, not just pain relief. A typical course is one to three injections depending on the product.

PRP (platelet-rich plasma). Your own blood is drawn, processed to concentrate the platelets and growth factors, and injected into the target tissue. The goal is to stimulate the body's own healing response. I use PRP for tendinopathy, mild to moderate joint arthritis, and certain ligament injuries.

Common injection targets

Shoulder (glenohumeral joint, subacromial bursa, AC joint, biceps tendon sheath), knee (joint, pes anserine bursa), hip (joint, trochanteric bursa, gluteal tendons), elbow (lateral and medial epicondyle), wrist (carpal tunnel, first dorsal compartment for de Quervain's), foot and ankle (plantar fascia, ankle joint, tarsal tunnel).

What to expect

The procedure takes about 10 to 15 minutes including the ultrasound assessment. I clean the skin, apply ultrasound gel, and guide the needle under direct visualization. Most patients feel pressure and a brief sting. I don't use sedation for these procedures because they're well-tolerated.

After the injection, I usually have you move the joint through its range of motion to distribute the medication. You can drive yourself home. Most people can return to normal activity the same day, with a few specific precautions depending on what was injected.

Recovery

For corticosteroid injections, there may be a temporary flare in pain for 24 to 48 hours before the anti-inflammatory effect kicks in. Full effect is usually felt within a week.

For viscosupplementation, avoid high-impact activity for 48 hours after injection. The benefit builds over the following weeks.

For PRP, expect some increased soreness for several days after injection. This is the inflammatory response we're trying to create. Avoid anti-inflammatory medications (ibuprofen, naproxen) for two weeks after PRP, as they blunt the healing cascade we just initiated.
