Abstract:
Objective To approach the treatment principle of lumbar spondylolisthesis with spina bifida occulta. Methods Twenty-six patients(male19,female 7,average 23.2 years old)with spondylolisthesis and spina bifida occulta were analyzed retrospectively.All cases were evaluated by radiological examinations including X-rays,computed tomography,magnetic resonance image.Based on the radiological results,the degeneration of intervertebual disc were varied by Ⅰ~Ⅴ types.Meyerdin’s score was used to evaluate the severe slip of the body of spondylolysis.At same time spina bifida occulta was divided into 4 models as follows,type A meant that the semi-lamina of sacrum was hypoplasia and still linked with spinous process;type B meant that the both sides of the lamina of sacrum was hypoplasia and the spinous process was free;type C meant that the lamina of sacrum was absent;type D meant that the spina bifida occulta was companied by other deformities such as the round formation of the end-plate of sacrum,the deformity of the transverse process of L5. Results The modality of the operations included 9 cases in single-vertabra fixation,13 cases in single-segment fixation,4 cases in two-segment fixation.All patients had been follow-up for 6~37 months(average 11.2 months).The effect of treatment was also obtained(8 in excellent,13 in good,5 in fair). Conclusions As for how to do with spondylolisthesis with spina bifida occulta(SBO),the type of SBO,degeneration scores of the disc and the degree of the slip of spondylolysis should be taken into consideration.
