The study investigates buttock pain in patients with lumbar disc herniation (LDH), identifying it as a common, independent symptom. It found that buttock pain is associated with contained herniation and an intact annulus fibrosus, and can be effectively treated with endoscopic discectomy.
• Buttock pain is common in patients with lumbar disc herniation (LDH), particularly in the L3–S1 segments, and is often independent of back and leg pain.
• The study examined 321 patients with single-level LDH who underwent endoscopic discectomy, finding that 75.4% experienced buttock pain.
• Buttock pain is more prevalent in patients with contained LDH and an intact annulus fibrosus.
• Endoscopic discectomy is effective in treating buttock pain, with significant improvements observed shortly after surgery and at the 1-year follow-up.
• The occurrence of buttock pain is not associated with age, sex, or specific spinal levels, indicating it as an independent symptom.
• The study suggests that altered intradiscal pressure may be a pathogenic factor for buttock pain in contained LDH.
• Residual buttock pain was more likely in L3–4 LDH, though the sample size for this segment was limited.
