Meta Analysis
Surgical Treatment of Tethered Cord Syndrome in Adults: A Systematic Review and Metanalysis.
In the healthy spine, the spinal cord moves unimpeded with spinal fluid pulsation in the rostral and caudal directions. When a portion of the spinal cord becomes attached to lesions within the spinal column, excess strain can cause signs and symptoms such as pain, motor deficits, sensory deficits, bladder dysfunction, and bowel dysfunction. This condition is termed tethered cord syndrome. There are no clear guidelines for offering surgical intervention, although there is a general consensus that worsening signs and symptoms increase the likelihood that patients will need surgery. ⋯ Tethered cord syndrome should be included in the differential diagnosis in patients presenting with back or leg pain, somatosensory symptoms of the lower extremities, muscular weakness, urodynamic dysfunction, or bowel dysfunction. After a definitive diagnosis is made, patients should be counseled about surgical detethering as an option.

Incisional negative pressure wound therapy (NPWT) is used in many surgical specialties to prevent postoperative dehiscence and surgical site infections (SSIs). However, little is known about the role of incisional NPWT in spine fusion surgery. Therefore, we sought to report a single surgeon's experience using incisional NPWT and describe its effects on dehiscence and SSIs after instrumented spine surgery. ⋯ NPWT decreases dehiscence and SSIs in patients undergoing lumbar fusion through an anterior approach. When preferentially used in patients at high risk for postoperative wound complications, NPWT prevents increased rates of dehiscence and SSI.

Bone cement augmentation with polymethylmethacrylate is a reliable method for stabilizing osteoporotic compression fractures and improving fixation of pedicle screws. However, cement extrusion into the vertebral venous system can result in pulmonary cement embolism. The goal of this anatomic study was to identify the relationship between the internal/external vertebral plexus and neighboring abdominal caval system. ⋯ An exact knowledge of the lumbar vertebral venous anatomy is essential when procedures that could affect the vertebral venous system are involved. Its complexity and anatomic variability necessitate such an understanding to better prevent/understand possible complications associated with polymethylmethacrylate extrusion.

Observational Study
Microdiscectomy for lumbar disc herniation - a single center observational study.
To examine outcomes and complications following first-time lumbar microdiscectomy. ⋯ Microdiscectomy for lumbar disc herniation is an effective and safe treatment.

The decision to restart systemic anticoagulation after surgery requires a nuanced risk-benefit analysis. The potential for surgical site bleeding must be balanced against the risk of thromboembolic events. ⋯ As a result, the decision of when to restart anticoagulation remains largely subjective and highly variable between surgeons and institutions. In this study, we aim to develop an algorithm that incorporates existing metrics and expert opinion toward the goal of developing guidelines for restarting anticoagulation after elective craniotomy.
