Retrospective study. ⋯ Hemilaminectomy or laminectomy remains one of the mainstay surgical treatments for symptomatic intraspinal synovial cysts. Our experience shows that the majority of patients undergoing decompression/excision of synovial cysts will have immediate improvement in back and leg pain. However, within 2 years, patients receiving hemilaminectomy or laminectomy alone have an increased incidence of back pain and cyst recurrence. Decompression with instrumented fusion appears to be associated with the lowest incidences of cyst recurrence or back pain.

Retrospective review. ⋯ C-arm CBCT with needle path overlay for fluoroscopic guided vertebroplasty is feasible and allows for reliable unilateral therapy of both lumbar and thoracic vertebral bodies. Extrapedicular approaches were performed safely and with good accuracy of reaching the targets.

Prospective cohort study. OBJECTIVE.: Estimate the prevalence of spondylolisthesis and determine the factors associated with higher or lower prevalence among men aged 65 years or older. ⋯ Spondylolisthesis may be more common among older men than previously recognized.

Comparative Study
Spinal fusion for spastic neuromuscular scoliosis: is anterior releasing necessary when intraoperative halo-femoral traction is used?
Retrospective radiographic and clinical study. ⋯ When intraoperative halo-femoral traction is used, PSF-only surgery for NMS can provide excellent curve correction and spinal balance. In this study, the PSF-only group had shorter OR time, lower EBL, lower frequency of postoperative intubation, and fewer cases of pneumonias when compared with A/PSF with similar radiographic outcomes at 2-year follow-up.

STUDY DESIGN.: Prospective, computer aided pedicle morphometric data measurements obtained from computed tomography (CT) scan of lower thoracic (T9-T12) and lumber vertebrae in a large group of Indian population. OBJECTIVES.: Measurement on CT scan of the surgically relevant parameters of transverse pedicle isthmus width, transverse pedicle angle, and depth to anterior cortex along the midline axis and the pedicle axis by Computer software aid in a large sample of Indian population. To compare the results with those of similar studies of Western and Indian population in literature by other methods and to deduce safety parameters for pedicular screw placements in these areas. ⋯ CONCLUSION.: Significant differences exist between the pedicles of Indian and white populations. It is suggested that preoperative software-based morphometric data should be collected if possible for preoperative planning of pedicle implant placement and sizes to avoid inadvertent complications. Further, data from study can be used as a guide for implant size, intraoperative placement trajectory at lower thoracic and lumber vertebrae pedicles.
