To report the use of a posterior based 'fusion mass screw' (FMS) as a primary or salvage fixation point in a revision spinal deformity following a previous posterior spinal fusion (PSF). Our experience of this technique in a case report and the clinical and radiological results are reported. ⋯ In this report, we present a novel method of using posterior FMSs to achieve fixation and correction in cases of revision deformity surgery with difficult anatomy. While we feel pedicle screws are the gold standard in deformity correction, knowledge of alternatives such as the FMS can allow surgeons to achieve stable constructs when faced with challenging situations.

Demonstrative case report of two different evolutions in developmental spondylolisthesis. To our knowledge spontaneous sacral doming reconstruction and healing has never been previously reported. ⋯ Sacral doming is secondary to L5 abnormal position regarding to S1. The mechanism of sacral doming looks like as an osteochondritis phenomena. Loss of support of the sacral plateau by sacral rounding may induce high grade spondylolisthesis.

The purpose of this study was to evaluate and compare disability, quality of life and satisfaction outcomes between young people and elderly who were operated on for degenerative lumbar disease. ⋯ Older patients can see substantial clinical improvement after degenerative lumbar disease surgery similar to that obtained in younger patients in terms of quality of life and satisfaction. The improvement in terms of the disability is greater for older patients. Thus, age should not be a contraindication for this procedure.

Symptomatic perineural cyst: report of two cases treated with cyst-subarachnoid shunts.
Symptomatic perineural cysts are rare. Resection and closure of such cysts sometimes results in postoperative neurological deficits and they can recur. We report two cases of symptomatic perineural cysts treated with subarachnoid shunts. ⋯ Cyst-subarachnoid shunts are a useful treatment option for symptomatic perineural cysts.

Microsurgical bilateral decompression via a unilateral approach for lumbar spinal stenosis is a less invasive technique compared to conventional laminectomy. Although many technical reports have demonstrated acceptable overall surgical outcomes for this approach, no studies have attempted to clarify the clinical outcomes thereof in regard to anatomical variance of the spinal canal. This study was conducted to analyze the clinical outcomes of microsurgical bilateral decompression via a unilateral approach according to spinal canal morphology in degenerative lumbar spinal stenosis. ⋯ Microsurgical bilateral decompression via a unilateral approach may be a good modality for treating round or oval shape spinal canal stenosis, but is not recommended for trefoil-shaped-stenosis. The current authors recommend performing the bilateral decompression technique in cases of trefoil-shaped-spinal canal stenosis.
