Discectomy Risks: Complications, Recovery, and Informed Consent

Discectomy (herniated disc removal) is generally safe and effective, but carries risks:

Common Risks

• Infection: Incisional or deep (discitis/epidural abscess) — ~1–2%
• Bleeding/hematoma: May compress nerves
• Nerve root injury: Transient or permanent weakness/numbness/pain — ~1–2%
• Dural tear (CSF leak): ~3–5%; usually repaired intraoperatively; may cause positional headache
• Recurrent herniation: 5–15% at same level

Less Common / Late Risks

• Segmental instability (esp. multi-level) → may need fusion
• Epidural fibrosis (scar tissue) → chronic radiculopathy
• Persistent post-surgical pain
• Anesthesia complications (rare)

Shared Decision-Making

Discuss with your surgeon: natural history without surgery, your specific pathology, expected benefit vs. risk profile, alternatives (PT, epidural steroid, observation).
