Minimally Invasive Pain and Spine Interventions (MIPSI) are advanced, non-surgical or “keyhole” procedures designed to treat chronic pain and spinal disorders with minimal disruption to the body. Unlike traditional open surgeries that require large incisions and muscle stripping, MIPSI techniques use small incisions (often less than 1 inch), natural body openings, and real-time imaging like fluoroscopy or ultrasound to target pain at its source.
Key Benefits of MIPSI
- Reduced Trauma: Avoids bone cutting and major muscle retraction, leading to less blood loss and minimal scarring.
- Faster Recovery: Most are day-care procedures, allowing patients to return home the same day and resume light duties within 1–4 days.
- Enhanced Safety: Often performed under local anaesthesia, making them safer for elderly or high-risk patients who cannot tolerate general anaesthesia.
- High Success Rates: General success rates for pain relief and functional improvement typically range from 85% to 95%.
Common MIPSI Procedures
MIPSIs are categorized based on the targeted “pain generator” in the spine.
- Epidural Interventions: Injections (e.g., Transforaminal Epidural Steroid Injection) deliver concentrated medication directly to irritated nerve roots to treat sciatica and slipped discs.
- Facet & SI Joint Procedures: Radiofrequency Ablation (RFA) uses heat to block pain signals from arthritic spinal joints, often providing relief for 1–2 years.
- Intradiscal Therapies: Techniques like Disc Annuloplasty or Biacuplasty use cooled RF to repair disc tears (annular tears) without surgery.
- Vertebroplasty/Kyphoplasty: Injections of bone cement to stabilize and relieve pain from osteoporotic compression fractures.
- Spine Endoscopy: A “keyhole” surgery using a tiny camera (endoscope) to remove herniated disc material or decompress pinched nerves.
Comparison with Traditional Surgery
| Factor | MIPSI | Traditional Open Surgery |
|---|---|---|
| Incision Size | Tiny (< 1 inch) | Large (several inches) |
| Hospital Stay | Outpatient / Day-care | 3–5 days |
| Anaesthesia | Local or Light Sedation | General Anaesthesia |
| Full Recovery | 4–6 weeks | 3–6 months |
Important Consideration: While highly effective for localized issues like disc herniations and stenosis, MIPSI may not be suitable for complex spinal deformities (e.g., severe scoliosis), multi-level instability, or tumors, which may still require traditional open surgery for comprehensive access.
