OBJECTIVETo investigate the causes and managements of postoperative neurological complications in pedicle screw internal fixation for the treatment of degenerative scoliosis (DS).

METHODSThe data of 325 patients with degenerative scoliosis underwent pedicle screw internal fixation was retrospectively analyzed from February 2000 to April 2013. There were 22 patients with postoperative neurological complications. Of them, 16 cases complicated with numbness or pain of lower limb and 6 cases with obvious sensation and motor function decreasing in lower limb. The patients were treated with trophic nerve, dehydration, glucocorticoids, reoperation according to the causes of disease. Postoperative at 3, 6 months and 1 year later, according to VAS scoring and muscule power improvement,the recovery of nerve injury was assessed.

RESULTSPostoperative at 3,6 months and 1 year later,VAS scoring of 16 patients with slightly nerve injury was 2.81 +/- 0.66, 1.94 +/- 0.77, 0.63 +/- 0.62, respectively, and the symptoms had obviously improved than 1 week after operation (P < 0.05). Postoperative at 3 months, among 6 patients with severe nerve injury,muscule power improved in 2 cases and no-improved in 4 cases, with VAS scoring of 4.83 +/- 1.17; postoperative at 6 months,muscule power still had not improved in 3 cases,with VAS scoring of 4.17 +/- 0.75; both of the VAS scoring had not significant difference than 1 week after operation (P > 0.05). One year later, there was no muscule power improvement in 2 cases,with VAS scoring of 3.00 +/- 1.26, there was significant difference than 1 week after operation (P < 0.05).

CONCLUSIONThe causes of postoperative neurological complication in internal fixation for the treatment of dengenerative scoliosis includes: dragging and torsion injury of spinal marrow and nerve root because of excessive orthopedic of scoliosis; inderect injury of nerve root because of malposition of pedicle screw; nerve functional impairment caused by spinal cord ischemia. Avoiding the above factors could decrease the complication and early discovery and treatment could decrease the adverse outcomes.
