Abstract
PDF - The minimally invasive plate osteosynthesis (MIPO) which is extensively performed, is very dependent on the indirect reduction technique to prevent the exposure of fracture sites. Indirect reduction with the use of the femoral distractor is a much more efficient technique to restore the length in the fracture of lower limbs. However, the femoral distractor cannot be used for fracture of upper limbs, and other instruments for indirect reduction have not yet been reported. Therefore, we introduce the novel indirect reduction technique with the use of the lumbar spreader for the MIPO of upper limbs.

- PURPOSE
To investigate factors influencing the amount of indirect reduction by ligamentotaxis according to timing of surgery, extent of surgery, and characteristics of fractures.
MATERIALS AND METHODS
We reviewed 22 cases of thoracolumbar fracture which had been performed posterior instrumentation and fusion using pedicle screw system. We divided patients into each group according to timing of surgery, number of fusion segment, insertion of screw on fractured vertebra, and rupture of posterior ligament complex, and Denis type. We measured changes of kyphotic angle, anterior vertebral height and wedge angle on plain radiographs, and we compared spinal canal area before and after operation using computed tomographic scans.
RESULTS
Kyphotic angle, anterior vertebral height, wedge angle, and area of spinal canal showed significant improvement postoperatively. The wedge angle improved significantly operated within 3 days after injury, however, kyphotic angle and anterior vertebral height had no correlation with variable factors except the rupture of posterior ligament complex. The amount of restoration of spinal canal also affected only by rupture of posterior ligament complex.
CONCLUSION
There is little relationship between timing of surgery and canal restoration, so we cannot conclude that prompt operation helps reduction of narrowed spinal canal. Otherwise narrowed spinal canal had much less restored by ligamentotaxis when there were rupture of posterior ligament complexes.
