Abstract
Objectives
In patients with fracture-dislocation of the lumbar spine with neurologic deficit and hemodynamic instability, minimally invasive surgery made/produced good clinical results. So the authors have reported the results with literature review
Summary of Literature Review
In patients with unstable lumbar spine fracture-dislocation, early surgical treatment has been preferred due to its many advantages of anatomical reduction, nerve decompression, recovery of nerve function, and early rehabilitation, etc. But for patients with unstable lumbar spine fracture-dislocation and who are hemodynamically unstable, the surgical treatment is generally delayed, so there are many cases that cannot fulfill the expectation of neurologic recovery.
Materials and Methods
In patients with unstable lumbar 2-3 spine fracture-dislocation and who are hemodynamically unstable, applying the concept of stage operation, postural reduction and minimal invasive percutaneous pedicle screw fixation were conducted as soon as possible. Then after recover of general condition, decompression and posterior fusion were conducted as a second stage operation.
Results
After the first stage operation, motor grade was improved from 3 to 4 below the L3 spine level in postoperative physical examination. The second stage operation was conducted two weeks later and neurologic symptom was more improved after the second stage operation.
Conclusions
In patients with lumbar spine fracture-dislocation having hemodynamic instability and neurologic deficit, early minimally invasive fixation for reducing complications of open reduction and internal fixation may contribute to improving general conditions and recovery of neurologic deficits.
