Does Removing the Spinal Tether in a Porcine Scoliosis Model Result in Persistent Deformity?: A Pilot Study
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.
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 VEPTR® Control Progression of Early-onset Kyphoscoliosis?: A Cohort Study of VEPTR® Patients With Severe Kyphoscoliosis
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.
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 (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.
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.
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
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.
The Cloward anterior interbody fusion is commonly performed for cervical disc herniation or spondylosis. In followup studies, various authors have noted clinically relevant adjacent-level degeneration. However, factors associated with adjacent-level degeneration are not well known.
Is Intraoperative CT of Posterior Cervical Spine Instrumentation Cost-effective and Does It Reduce Complications?
Symptomatic multilevel cervical myelopathy is often addressed using posterior decompression using two-dimensional fluoroscopy. Intraoperative three-dimensional fluoroscopy provides more accurate information on the position of instrumentation to prevent screw-related complications.
