Because neither the degree of constriction of the spinal canal considered to be symptomatic for lumbar spinal stenosis nor the relationship between the clinical appearance and the degree of a radiologically verified constriction is clear, a correlation of patient's disability level and radiographic constriction of the lumbar spinal canal is of interest.

An incidence of pulmonary cement embolism of 6.8% during PV was found. Close clinical follow-up, postprocedural chest radiographs, and chest CT scans, if necessary, are important for the detection of pulmonary cement embolism at an early stage.

Level II, prospective case series.

In patients requiring spine surgery due to neurologic deficit and having no sufficient time for the medical treatment of severe osteoporosis, pedicle screw fixation with vertebroplasty augmentation and vertebroplasty in segments proximal and distal to the instrumented segments can be good alternative methods to provide well fixation and fusion while preventing proximal and distal junctional fractures. One should be careful about pulmonary cement embolism after such kind of procedures.

The simultaneous surgical treatment for congenital deformity and intraspinal abnormality does not involve significant complications and seems to be an alternative and safe treatment option.
