Failed back surgery syndrome: casuistic and etiology

Area of Science:

• Neurosurgery
• Orthopedics
• Spinal Surgery

Background:

• Failed back surgery syndrome (FBSS) is a significant clinical challenge.
• Etiologies of FBSS include surgical and nonsurgical factors.
• Identifying causes is key to improving patient outcomes.

Purpose of the Study:

• To analyze the incidence and characteristics of FBSS in patients undergoing spinal surgery.
• To investigate the pre-surgical diagnoses associated with FBSS.
• To contribute to the understanding of FBSS etiologies.

Main Methods:

• Retrospective review of 121 patients undergoing laminectomy, hemilaminectomy, discectomy, and/or foraminotomy.
• Inclusion criteria: persistent or recurrent symptoms post-surgery with adequate diagnostic workup.
• Patients categorized by pre-surgical diagnoses: herniated disc, lumbar stenosis, or both.

Main Results:

• 47 out of 121 patients (38.8%) met criteria for FBSS.
• FBSS incidence varied by pre-surgical diagnosis: 30.7% for lumbar stenosis, 37.3% for disc herniation, and 58.3% for combined stenosis and herniation.
• The association of lumbar stenosis and disc herniation showed the highest FBSS rate.

Conclusions:

• FBSS remains a complex challenge in spine surgery.
• Further research into the causes and mechanisms of FBSS is essential.
• Optimizing treatment strategies for FBSS requires a thorough understanding of its origins.
