Postoperative expansion of dural sac cross-sectional area after unilateral laminotomy for bilateral decompression: correlation with clinical symptoms.
Dural sac cross-sectional area (DSCSA) is a way to measure the degree of central spinal canal compression. The objective was to investigate the correlation between the expansion ratio of DSCSA after unilateral laminotomy for bilateral decompression (ULBD) and the clinical results for lumbar spinal stenosis. ⋯ Our result indicates that the DSCSA itself has a definite limitation to be correlated to the clinical symptoms, and thus meticulous correlation between the clinical presentation and MRI imaging is essential in determination of surgical treatment.

Effectiveness of Repeated Radiofrequency Neurotomy for Facet joint Syndrome after Microscopic Discectomy.
Postoperative facet joint syndrome requiring radiofrequency neurotomy (RFN) is a relatively common problem following microscopic discectomy. However, the efficacy of repeated RFN after microscopic discectomy has not been clearly documented. The purpose of this study was to determine the success rate and symptom-free duration of repeated RFN for facet joint syndrome after microscopic discectomy. ⋯ Repeated RFN for lumbar facet joint pain after microscopic discectomy is an effective palliative treatment. It provided a mean duration of relief of 9.0 months and >94% success rate.

Lumbar disc herniations 'to operate or not' patient selection and timing of surgery.
At times lumbar disc herniations present a quandary to the spine surgeon in regards to the most appropriate intervention and a need to optimize medical and surgical therapies. We discuss a case of ours and our experience in treating this common spinal pathology, along with a commentary on the article published by Kim et al. entitled 'Spontaneous regression of extruded lumbar disc herniation: three cases report in Korean J Spine. 2013 Jun;10(2):78-81.'
