Previous publications have reported results with respect to functional outcome and sexual function in young women after traumatic injuries to the pelvis. It is well known that anterior spinal surgery has the possibility of causing reproductive dysfunction in men. Little has been described concerning deleterious effects of anterior spinal surgery in women of childbearing age. ⋯ Although the cesarean-section rate appears high, it is consistent with the current obstetrical trends. Anesthesiologists appear less inclined to offer neuraxial anesthesia to a population which has undergone anterior spinal surgery.

Multicenter Study
Do 1-year outcomes predict 2-year outcomes for adult deformity surgery?
Health-related quality-of-life (HRQOL) measures are being used more frequently in the evaluation of the adult deformity patient. This is due in part to the validation of the deformity-specific Scolios Research Society-22 (SRS-22). Hence, relationships between HRQOL outcomes and traditional measures of success such as deformity correction, fusion healing, and complications are being established. ⋯ This study supports the application of HRQOL measures, including the deformity-specific SRS-22, as a valuable tool in the assessment of adult deformity patients. Change in outcome score stabilized after the 1-year postoperative interval, for most patients.

Comparative Study
All pedicle screw instrumentation for Scheuermann's kyphosis correction: is it worth it?
Scheuermann's kyphosis has long been treated by a two-staged fusion and instrumentation with a hybrid construct using hooks, pedicle screws, and sublaminar wires. Recent interest in all pedicle screw constructs led to its use in the treatment of Scheuermann's kyphosis. Evaluation of this newly described application is needed. ⋯ The use of multiple-level all pedicle screws technique allowed a rigid anchor for posterior correction of the deformity with less operative time, blood loss, and hospital stay without the need for anterior release. A better correction was achieved and preserved with the use of all pedicle screw constructs. This technique is a useful modality in the treatment of Scheuermann's kyphosis.

Somatosensory evoked potential (SSEP) is used to monitor integrity of the brain, spinal cord, and nerve roots during spinal surgery. It records the electrical potentials from the scalp after electrical stimulation of the peripheral nerves of the upper or lower limbs. The standard monitoring modality in lumbosacral spine surgery includes lower-limb SSEP and electromyography (EMG). Upper-limb SSEP monitoring has also been used to detect and prevent brachial plexopathy and peripheral nerve injury in thoracic and lumbosacral spine surgeries. We routinely monitor lower-limb SSEP and EMG in lumbosacral spine procedures at our institution. However, a few patients experienced postoperative numbness and/or pain in their ulnar distribution with uneventful lower-limb SSEP and EMG. ⋯ The present study demonstrates that upper-limb SSEP monitoring could detect position-related ulnar neuropathy in 5.2% of the patients undergoing lumbosacral spine surgery.

Case Reports
Spinal dural arteriovenous fistula with hematomyelia caused by intraparenchymal varix of draining vein.
Hemorrhage that results from spinal dural arteriovenous fistula (Type I arteriovenous malformation [AVM]) is uncommon. There are some reports of subarachnoid hemorrhage and subdural hematoma caused by Type I spinal AVM, but there are few reported cases of hematomyelia caused by spinal dural arteriovenous fistula. ⋯ It must be kept in mind that spinal dural arteriovenous fistulas (Type I spinal AVM) has possibility of hematomyelia origin, despite the fact that it is extremely rare.
