Area of Science:

  • Orthopedics
  • Neurosurgery
  • Spinal Surgery

Background:

  • The Cotrel-Dubousset pedicle screw system was evaluated for its efficacy in treating a diverse range of spinal conditions.
  • This study included 85 patients with diagnoses including degenerative lumbar disorders, spinal trauma, deformities, and tumors.

Observation:

  • The system demonstrated versatility, extending beyond standard thoracic to sacrum fixation.
  • It proved beneficial for specific procedures like slipped vertebra reduction and spinal deformity correction, even with anterior instrumentation.

Findings:

  • Postoperative clinical results were generally positive across the patient cohort.
  • A notable complication was pseudarthrosis, which negatively impacted outcomes in a subset of cases.
