Summary
Automated percutaneous lumbar discectomy (APLD) showed a 45% success rate for symptomatic lumbar disc prolapse. Many patients experienced long-term issues, indicating APLD may not provide lasting relief for back pain.
Area of Science:
- Neurosurgery
- Orthopedics
- Minimally Invasive Procedures
Background:
- Symptomatic lumbar disc prolapse is a common cause of back pain and disability.
- Automated percutaneous lumbar discectomy (APLD) is a minimally invasive surgical option.
- Long-term outcomes and patient-reported success rates of APLD require further investigation.
Purpose of the Study:
- To evaluate the long-term efficacy and patient-reported outcomes of automated percutaneous lumbar discectomy (APLD).
- To assess the reoperation rate and functional status following APLD for lumbar disc prolapse.
Main Methods:
- A cohort of 137 patients with symptomatic lumbar disc prolapse underwent APLD.
- Outcomes were assessed using clinical grading, Oswestry scores, employment status, and the Short Form 36 health survey.
- Mean follow-up was 55 months.
Main Results:
- The overall success rate at mean follow-up was 45%.
- Among patients treated with APLD alone, 52% had excellent or good outcomes, with 76% employed and a mean Oswestry score of 28.2%.
- One-third of initially successful patients experienced symptom deterioration, and the Short Form 36 indicated a chronic ill-health profile.
Conclusions:
- APLD demonstrated a moderate long-term success rate for symptomatic lumbar disc prolapse.
- A significant proportion of patients, even those initially successful, experienced symptom recurrence and chronic disability.
- The findings suggest a need for careful patient selection and realistic outcome expectations for APLD.
