Convex Instrumented Hemiepiphysiodesis with Concave Distraction: A Preliminary Report

Ahmet Alanay MD, Ozgur Dede MD, Muharrem Yazici MD

The convex growth arrest (CGA) procedure has been well accepted for treatment of congenital scoliosis as it is a simpler procedure with successful results. However, unpredictability of curve behavior, slow and usually inadequate correction, and necessity of anterior surgery for completeness of the epiphysiodesis are its shortcomings.

Cervical Spine Surgery: An Historical Perspective

Vincenzo Denaro MD, Alberto Di Martino MD, PhD

Continued innovation in surgery requires a knowledge and understanding of historical advances with a recognition of successes and failures.

Does Removing the Spinal Tether in a Porcine Scoliosis Model Result in Persistent Deformity?: A Pilot Study

Ashish Patel MD, Frank Schwab MD, Renaud Lafage BS, Virginie Lafage PhD, Jean Pierre Farcy MD

Using a tethering technique, a porcine model of scoliosis has been created. Ideally, tether release before placement and evaluation of corrective therapies would lead to persistent scoliosis.

Bilateral Rib-to-pelvis Technique for Managing Early-onset Scoliosis

John T. Smith MD

Early-onset scoliosis describes progressive spinal deformity of varying etiologies in the growing child. The management of early-onset scoliosis is challenging, with many treatment options but no conclusive evidence for the best treatment method.

Can VEPTRĀ® Control Progression of Early-onset Kyphoscoliosis?: A Cohort Study of VEPTRĀ® Patients With Severe Kyphoscoliosis

Kent Reinker MD, James W. Simmons DO, PhD, Vishwas Patil MD, Zachary Stinson MD

Kyphoscoliosis is considered a relative contraindication to treatment with the Vertical Expandable Prosthetic Titanium Rib (VEPTR; Synthes Inc, Paoli, PA). Nevertheless, patients do present with early-onset kyphoscoliosis and thoracic insufficiency syndrome, and no suitable alternative treatments are currently available. However, it is unclear whether VEPTRis reasonable for treating patients with kyphoscoliosis.

The Best Surgical Treatment for Type II Fractures of the Dens Is Still Controversial

Vincenzo Denaro MD, Rocco Papalia MD, PhD, Alberto Di Martino MD, PhD, Luca Denaro MD, PhD, Nicola Maffulli MD, MS, PhD, FRCS(Orth)

Odontoid fractures are the most common odontoid injury and often cause atlantoaxial instability. Reports on postoperative status of patients who underwent surgery for such injuries are limited to small case series, and it is unclear whether any one technique produces better outcomes than another.

Spinal Cord Injury: A Systematic Review of Current Treatment Options

David W. Cadotte MSc, MD, Michael G. Fehlings MD, PhD, FRCSC, FACS

Spinal cord injury (SCI) is a devastating event often resulting in permanent neurologic deficit. Research has revealed an understanding of mechanisms that occur after the primary injury and contribute to functional loss. By targeting these secondary mechanisms of injury, clinicians may be able to offer improved recovery after SCI.

Laminoplasty versus Laminectomy and Fusion for Multilevel Cervical Spondylotic Myelopathy

Barrett I. Woods MD, Justin Hohl MD, Joon Lee MD, William Donaldson MD, James Kang MD

Cervical spondylotic myelopathy is increasingly prevalent in the elderly and is the leading cause of spinal cord dysfunction in this population. Laminectomy with fusion and laminoplasty halt progression of myelopathy in these patients; however, both procedures have well-documented complications and associated morbidity and it is unclear which might be most advantageous.

Operated and Adjacent Segment Motions for Fusion versus Cervical Arthroplasty: A Pilot Study

Tomoya Terai MD, PhD, Ahmad Faizan PhD, Koichi Sairyo MD, PhD, Vijay K. Goel PhD

Anterior cervical discectomy and fusion (ACDF) represent the standard treatment for cervical spondylolytic radiculopathy and myelopathy. To achieve solid fusion, appropriate compressive loading of the graft and stability are essential. Fusion may lead to adjacent segment degeneration. Artificial discs have been introduced as motion-preserving devices to reduce the risk of fusion-related complications.

Patients With Cervical Metastasis and Neoplastic Pachymeningitis are Less Likely to Improve Neurologically After Surgery

Vincenzo Denaro MD, Alberto Di Martino MD, PhD, Rocco Papalia MD, PhD, Luca Denaro MD, PhD

Although many patients with cervical spine metastases are treated surgically, it is unknown whether certain subsets achieve better pain relief and improvement of neurologic function.
