Abstract:
There is a broad range of lumbar pedicular and neural arch anomalies, with spina bifida occulta and spondylolysis being especially common. It is very rare for a pedicular cleft to be associated with contralateral spondylolysis in the same vertebral segment. We observed L4 spondylolisthesis, clefting of the left L4 hypertrophied pedicle associated with contralateral spondylolysis, and spinal stenosis on a radiographic study of the lumbar spine. Operative treatment was performed, with posterior decompression, partial removal of the hypertrophied pedicle, posterior lumbar interbody fusion using a cage, and posterior instrumentation. The patient's neurologic symptoms resolved after operative treatment. Fusion of the left pedicle cleft was observed on 6-month follow-up CT. We report one case of pedicular cleft fusion using pedicle screw fixation and present a review of the relevant literature.
