Summary
Posterior decompression and pedicular screw fixation effectively treated lumbar scoliosis with spinal stenosis and neurogenic claudication. Patients experienced significant pain reduction and deformity correction, with no major complications.
Area of Science:
- Orthopedics
- Neurosurgery
- Spinal Surgery
Background:
- Lumbar scoliosis often coexists with spinal stenosis, causing neurogenic claudication and significant pain.
- Surgical intervention is frequently required for severe cases unresponsive to conservative management.
Purpose of the Study:
- To evaluate the efficacy of posterior decompression and pedicular screw fixation in patients with lumbar scoliosis and spinal stenosis.
- To assess pain reduction, functional improvement, and deformity correction following surgical treatment.
Main Methods:
- Retrospective review of 40 patients with lumbar scoliosis, spinal stenosis, and neurogenic claudication.
- All patients underwent posterior decompression and pedicular screw fixation, with various instrumentation techniques used (Zielke, Cotrel-Dubousset, TSRH).
Main Results:
- Significant improvement in pain: 83% severe pain pre-op vs. 93% mild/no pain post-op.
- Mean scoliosis correction of 19 degrees (37 to 18 degrees).
- No deaths, instrument failures, or pseudarthroses observed during an average 44-month follow-up.
Conclusions:
- Posterior decompression with pedicular screw fixation is a safe and effective treatment for lumbar scoliosis associated with spinal stenosis.
- This surgical approach yields substantial pain relief and deformity correction in affected patients.

01:16Vertebral Column: Regions and Curvature
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
