Lumbar spine
Injection of the piriformis and iliopsoas muscles, trochanteric bursitis
The deep muscles of the lumbar and pelvic region and the greater trochanter bursa can be reached with an ultrasound-guided needle to treat referred pain and local inflammation.
How it is performed
Pain that radiates from the back down to the buttock, hip or groin does not always originate from the spine. The piriformis muscle can irritate the sciatic nerve, the iliopsoas tendon can become inflamed deep in front of the hip, and the greater trochanter region is a typical site of gluteal tendinopathy and bursitis. Ultrasound allows each of these structures to be reached with precision, avoiding vessels and nerves, and to deposit anaesthetic and anti-inflammatory medication there.
Who it is for
- Piriformis syndrome with buttock pain and pseudo-sciatica
- Groin pain from iliopsoas tendinopathy/bursitis
- Greater trochanteric pain syndrome (lateral hip pain, pain when lying on the side)
Recovery
You can walk immediately after the procedure. In the following days a targeted exercise programme is recommended, which strengthens and extends the benefit of the injection.
Conditions treated in this area: chronic low back pain, disc herniation and sciatica, sacroiliac joint pain, muscle tension and pain (paraspinal, piriformis).
Scientific evidence
Randomised studies show the effectiveness of ultrasound-guided piriformis injection in reducing pain and disability in piriformis syndrome. For greater trochanteric pain syndrome, meta-analyses indicate that injection provides rapid relief, while therapeutic exercise is key to long-term outcomes: the combined approach is the one recommended.
