Cerebrospinal fluid (CSF) leak is a complication of spinal surgery. Intraoperative or postoperative identification of a CSF leak often results in wound healing complications, lumbar drain placement, and/or reoperation. These complications usually extend a patient's hospital stay, can be painful, and have their own associated risks. The authors describe a technique that may improve on traditional interventions by managing postoperative CSF leaks after lumbar instrumentation without an additional procedure or extended hospitalization. ⋯ Our study suggests that routine intraoperative subfascial JP drain placement aids in the early diagnosis of postoperative lumbar CSF leak. Primary closure of dural tear remains the standard of care. Furthermore, in select cases, prolonged JP drainage in the setting of postoperative CSF leak may be a useful technique for the treatment of these leaks.

Case Reports
Lumbar hemorrhagic synovial cysts: diagnosis, pathogenesis, and treatment. Report of 3 cases.
To define the etiologic, clinical, histological, and surgical features of lumbar hemorrhagic synovial cysts (LHSCs). Three personal cases are reported together with a review of the pertinent literature. ⋯ Hemorrhagic synovial cyst of the spine is rare and its most common localization is lumbar. Bleeding within the cyst leads to an increase of its volume, accompanied by neurological deficits and/or painful symptoms that are violent and generally intractable. In this event, surgical excision is the treatment of choice and, in some cases, emergency surgery is necessary. Hemorrhages are probably caused by the rupture of fragile neoangiogenic vessels.

Case Reports
Spinal compression due to ossified yellow ligament: a short series of 5 patients and literature review.
Ossification of ligamentum flavum in the thoracic region causing compressive myelopathy among middle-aged patients is a poorly described entity. ⋯ Decompressive laminectomy and excision of the OYL is the commonly performed surgical procedure. A rapid neurologic improvement follows decompression. The persistent spasticity in certain patients is attributed to irreversible changes within the cord. The disease is thought to be progressive in nature. The prolonged follow-up of these patients suggests that the long-term prognosis is poor. Selective racial involvement and variable clinical presentations, with treatment options, are discussed.

The contribution of MER to improving bilateral STN-DBS is debatable. To resolve the controversy and elucidate the role of MER in DBS, we compared the outcome of bilateral STN-DBS surgery with and without MER in parkinsonian patients. ⋯ Although STN-DBS is a promising surgical modality for advanced parkinsonian patients, there is an inevitable learning curve associated with adopting this new procedure. Intraoperative MER is an effective way to ensure correct electrode placement in the STN. With the assistance of intraoperative MER, the outcome of STN-DBS can be improved significantly.
