Case ReportsAnterior fusion and posterior correction of severe cervical kyphosis using pedicle screw fixation in a patient with neurofibromatosis: a case report.
We present a 15-year-old boy with severe cervical kyphosis due to neurofibromatosis (NF), who underwent one-stage anterior fusion and posterior correction using pedicle screw fixation. The kyphosis was corrected from 72 degrees to 35 degrees. At the follow-up 16 months postoperatively, anterior fusion and posterior stabilization had been obtained without correction loss. Cervical pedicle screw fixation is a useful method for the correction of severe cervical kyphosis in patients with NF.

Comparative StudyComparison of motion restriction and trunk stiffness provided by three thoracolumbosacral orthoses (TLSOs).
The amounts of thoracic and lumbar spine motion restriction and passive trunk stiffness provided by three thoracolumbosacral orthoses (TLSOs) (Aspen TLSO, Boston Body Jacket, and CAMP TLSO) were compared. Ten subjects executed maximum trunk flexion, extension, and lateral bending motions. ⋯ The subjects also did not perceive any difference in the restriction of motion but rated the Aspen TLSO significantly more comfortable than the other two orthoses. The rigid custom orthosis design may not be important for restricting the spine motion and providing passive trunk stiffness, or there may be other measures that reflect better the function of orthoses.

This retrospective study was designed to document the incidence and types of perioperative complications that occurred with anterior spinal fusion surgery performed solely by an orthopedic spine surgeon. This study is contrasted to previous studies that document complications from anterior approaches performed by an orthopedic surgeon with the assistance of a general or a vascular surgeon. Specifically, the procedures included thoracotomies, thoracolumbar retroperitoneal, and lumbosacral approaches. ⋯ Average follow-up was 41.69 months, with a minimum of 12 months and a maximum of 132 months. Our results indicated that anterior procedures performed solely by our senior orthopedic surgeon had a lower incidence of complications, less blood loss, and shorter operative time than anterior procedures performed by an orthopedic surgeon and a vascular or a general surgeon. Our findings suggest that the anterior spinal exposure is a safe approach that may be performed solely by a spinal surgeon who is knowledgeable and experienced.

Multicenter Study Clinical TrialPosterior lumbar interbody fusion for degenerative disc disease using a minimally invasive B-twin expandable spinal spacer: a multicenter study.
Acquired degenerative disc disease causes gradual disc space collapse, concurrent discogenic or facet-induced pain, and possible compression radiculopathy. Surgical treatment aims to re-expand the intervertebral space and stabilize the involved segment in balanced alignment until fusion is complete. The prevailing methods make use of a twin cage device of predetermined size. ⋯ Disc space height that averaged 7.53 +/- 2.42 mm before surgery increased to 10.03 +/- 2.00 mm at the time of surgery and stabilized at 9.47 +/- 2.10 mm upon final follow-up. Visual Analog Scale and Oswestry Index decreased by 60% and 58%, respectively. PLIF using the ESS achieves the same ultimate outcome as do other methods currently in use but does not share the handicaps and hazards and is more user-friendly to the surgeon.

Clinical TrialProspective study evaluating total disc replacement: preliminary results.
For many years, there has been an interest in disc replacements. There are a few retrospective studies from Europe reporting promising results for these devices. The purpose of this study is to review the preliminary results of the SB Charité disc replacement device in a prospective study. ⋯ This study found that significant improvements were achieved by the 6-week postoperative visit in the pain and disability scores following disc replacement surgery. Significant improvement was maintained through the 12-month follow-up visit. Although these preliminary results are encouraging, long-term follow-up and a greater number of patients are needed to further evaluate the outcome of these devices.
