Purpose:
To evaluate the short-term efficacy and safety of ultrasound-guided hydrodissection alone versus hydrodissection combined with acupotomy release for deep gluteal syndrome (DGS).
Methods:
This retrospective study included 82 patients with DGS, divided into a hydrodissection group (n = 41) and a combined hydrodissection with acupotomy group (n = 41). Both groups underwent ultrasound-guided sciatic nerve hydrodissection; the combined group additionally received acupotomy to incise surrounding fascia. Primary outcomes were changes in Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores at two weeks post-treatment.
Results:
No complications (eg, bleeding, nerve injury) occurred in either group from immediately post-treatment to two weeks. At two weeks, both groups showed significant improvements in VAS and ODI scores compared to baseline (P<0.001)). The combined group had greater VAS improvement [median (IQR): 4.00 (4.00, 5.00)] than the hydrodissection group [3.00 (2.00, 4.00); P < 0.001] and greater ODI improvement [40 (20, 60) vs 20 (20, 30); P = 0.004].
Conclusion:
Ultrasound-guided hydrodissection combined with acupotomy release was associated with greater short-term pain relief (VAS) and functional improvement (ODI) in patients with DGS compared with hydrodissection alone.
