Schwannomas originating from the oculomotor nerve are extremely rare. We report our experience in the management of oculomotor schwannomas and other lesions mimicking them, and discuss operative strategy for these rare tumors emphasizing oculomotor nerve preservation. ⋯ The microsurgical resection of oculomotor schwannomas carries a risk of worsening preoperative oculomotor nerve function; however, this is often transient. Considerable technical training and microanatomical knowledge of the region is required to optimize outcome.

Orbital lymphangiomas (OL) are rare benign lesions that represent less than 4% of all space-occupying orbital lesions. Total surgical resection is usually difficult because of its infiltrative nature. Our objective was to analyze the indications for surgical treatment, the selection of surgical approach, and the clinical outcome after surgical treatment of OL. ⋯ Subtotal resection of OL is an effective and safe treatment option, may prevent new hemorrhagic episodes, and is not associated with a high recurrence rate after a relatively short-term follow-up. Progressive proptosis, visual or oculomotor impairment, and repeated symptomatic hemorrhagic episodes are considered indications for surgery. Transcranial access should be performed in large tumors extending posteriorly.

Traumatic spinal fracture is a common indication for surgery, with an associated high incidence of perioperative complications. The literature provides a wide range in the incidence of complications. We seek to assess the perioperative morbidity and mortality of surgery for traumatic spinal fractures and to identify predictors of their occurrence. ⋯ Overall, surgery for the treatment of spinal fractures was performed with relatively low incidences of perioperative complications (6.9%) and mortality (0.5%). These data may prove useful for patient counseling and ongoing efforts to improve the safety of operative care for patients with spinal fracture.

To report the results of use of a human oscillating field stimulator (OFS) in a phase 1 trial of 14 human patients with complete motor and sensory spinal cord injury. ⋯ Treatment of human spinal cord injury with an OFS is safe, reliable, and easy. Compared with National Acute Spinal Cord Injury Study III compliant paralyzed patients, our results suggest efficacy.

Minimally invasive spinal surgery (MISS) has many favorable attributes that would be of great benefit to patients with an adult spinal deformity. Decreased blood loss, lower infection rates, and faster mobilization may help to reduce the high rate of complications associated with these interventions. Although correction of coronal deformity has been well demonstrated with MISS, improvements in lordosis and sagittal balance have remained relatively elusive using the MISS approach. With open surgery, the most powerful techniques for improving sagittal balance include some form of a spinal osteotomy. ⋯ The correction of sagittal plane deformities remains difficult using MISS approaches. In this report, we describe a new technique using a mini-open PSO technique to achieve significant improvement in thoracolumbar lordosis.
