Summary
Pedicle screw fixation effectively treats thoracolumbar fractures by correcting kyphosis and reducing pain. This method offers safe and reliable spinal stabilization for traumatic vertebral injuries.
Area of Science:
- Orthopedic Surgery
- Spinal Surgery
- Traumatology
Background:
- Intermediate screws in fractured vertebrae act as pressure points, correcting kyphosis and providing three-point fixation.
- This mechanism reduces the lever effect in spinal trauma management.
Purpose of the Study:
- To evaluate the outcomes of non-pathologic traumatic thoracolumbar spine fractures treated with instrumentation.
- To describe the clinical course following surgical intervention.
Main Methods:
- Retrospective analysis of 37 patients (T9-L4) operated between 2008-2012.
- Patients included 28 males and 9 females with a mean age of 41.8 years.
Main Results:
- Restoring spinal canal diameter increased neurologic improvement by 2.11 times.
- Autologous grafts showed a relative fusion risk of 0.97 compared to heterologous grafts.
- Instrumentation of the fractured vertebra had a relative risk of 1.18 for fusion.
Conclusions:
- Pedicle screw fixation at the fracture level is a safe and effective treatment for thoracolumbar fractures.
- It aids in fracture reduction, kyphosis correction, and pain management.
- Indications include an intact posterior ligament complex and at least one intact pedicle.
