Περίληψη:
From 1996 to 1998, 30 consecutive patients with Level I thoracolumbar
spinal injury were classified and treated according to the Gertzbein
classification and the load sharing classification. A posterior short
segment pedicle screw implant was used in 21 patients; anterior
decompression with strut grafting and application of the Kaneda device
was used in three patients; and six patients were treated with short
posterior instrumentation and an anterior strut graft. The average
followup was 32 months (range, 24-50 months). The clinical outcome was
satisfactory in 22 of 30 patients. Five of nine patients had neurologic
improvement. Radiographic imaging findings showed a slight loss of
reduction, but the clinical outcome of the patients was not affected. No
pseudarthrosis and no implant failures were recorded. The Gertzbein
classification correlates the type of fracture with the degree of
mechanical instability and neurologic lesion. The load sharing
classification correlates fracture comminution and displacement with
mechanical stability and implant failure. Patient selection is a
fundamental component for a successful outcome. The best candidates for
surgery are cooperative patients who require spinal mobility, patients
who are able to tolerate a two-stage reconstruction, and patients in
good general health.
