Introduction:
We report our experience of five cases in adolescents with spastic quadriplegia who had primarily sagittal plane deformity with hyperlordosis of the lumbar spine, an uncommon condition in cerebral palsy spinal deformity.
Methods:
Three boys and two girls, 13 to 19 years old, were surgically treated for excessive lumbar lordosis which made sitting difficult. Bilateral hip flexion contractures were present in all cases with a very horizontal sacrum and, in four cases, associated with pelvic anteversion. Two patients were surgically treated by posterior spinal fusion and instrumentation, and three patients had anterior discectomy and fusion prior to posterior fusion and instrumentation.
Conclusion:
Hyperlordosis was reduced by 26 to 48 degrees , and the horizontal sacrum was corrected by 15 to 35 degrees , which enabled the patients to sit comfortably.
