Limited Sequence MRIs for Early Onset Scoliosis Patients Detected 100% of Neural Axis Abnormalities While Reducing MRI Time by 68%
Study Design. Diagnostic accuracy. Objective. The purpose of this study was to determine if neural axis abnormalities in early onset scoliosis (EOS) patients can be reliably detected with limited magnetic resonance imaging (MRI) sequences (sagittal T1, sagittal T2). Summary of Background Data. MRIs are often performed in EOS patients as studies have shown there are neural axis abnormalities in up to 40% of this population. MRIs are expensive, lengthy, and often require general anesthesia....

Preoperative Assessment of Bone Quality in Spine Deformity Surgery: Correlation With Clinical Practice and Published Recommendations
Study Design. Retrospective cohort study. Objective. The goals of this study were to (A) evaluate preoperative bone quality assessment and intervention practice over time and (B) review the current evidence for bone evaluation in spine fusion surgery. Summary of Background Data. Deformity spine surgery has demonstrated improved quality of life in patients; however, its cost has made it controversial. If preoperative bone quality can be optimized then potentially these treatments could...

Vertebral Growth Around Distal Instrumented Vertebra in Patients With Early-Onset Scoliosis Who Underwent Traditional Dual Growing Rod Treatment
Study Design. Retrospective radiographic study. Objective. To investigate the growth of the vertebrae around distal instrumented vertebra (DIV) in patients with early-onset scoliosis (EOS) who underwent dual growing rod (DGR) treatment. Summary of Background Data. Previous studies indicated that DGR was likely to preserve or even stimulate the spinal growth. However, report pertaining to the effect of growing rod on the growth of individual vertebral body is rare. Methods. The EOS...

Long-term Tumor Control With Radiotherapy for Symptomatic Hemangioma of a Vertebral Body
Study Design. Retrospective outcomes review. Objective. To analyze and report long-term outcomes in a cohort of patients treated with radiotherapy (RT) for symptomatic hemangioma of a vertebral body. Summary of Background Data. Data are scarce on the rate of tumor control with long-term (>5 yr) follow-up after RT for symptomatic hemangioma of a vertebral body. Methods. We retrospectively reviewed the medical records of patients treated at our institution between 1971 and 2008...

Risk Factors for Rapidly Progressive Neurological Deterioration in Cervical Spondylotic Myelopathy
Study Design. A retrospective single-center study. Objective. This study sought to clarify the risk factors and to evaluate the surgical outcome in patients with rapidly progressive cervical spondylotic myelopathy (rp-CSM). Summary of Background Data. CSM is a degenerative spine disease presenting a slow development of myelopathy. Some patients, however, show rapidly progressive neurological deterioration (especially gait disturbances) without any trauma. At present, there is little...

Poor Baseline Mental Health Does Not Influence Improvement in Patient-reported Outcomes, Satisfaction, and Return to Work Two Years After Single-level Anterior Cervical Discectomy and Fusion
Study Design. Retrospective study using prospectively collected registry data. Objective. The authors examine the influence of preoperative mental health on outcomes after anterior cervical discectomy and fusion (ACDF) and determine the impact of ACDF on postoperative mental health. Summary of Background Data. While studies have reported a negative correlation between preoperative mental health and outcomes following lumbar spine surgery, the influence on outcomes following cervical...
