Mirror movements are unintended movements occurring on one side of the body that mirror the contralateral voluntary ones. It has been proposed that mirror movements occur due to abnormal decussation of the corticospinal pathways. Using detailed multidisciplinary approach, we aimed to enlighten the detailed mechanism underlying the mirror movements in a case subject who is diagnosed with mirror movements of the hands and we compared the findings with the unaffected control subjects. To evaluate the characteristics of mirror movements, we used several techniques including whole exome sequencing, computed tomography, diffusion tensor imaging and transcranial magnetic stimulation...

Interspinous process devices (IPDs) have been developed as less-invasive alternatives to spinal fusion with the goal of decompressing the spinal canal and preserving segmental motion. IPD implantation is proposed to treat symptoms of lumbar spinal stenosis that improve during flexion. Recent indications of IPD include lumbar facet joint syndrome, which is seen in patients with mainly low-back pain. Long-term outcomes in this subset of patients are largely unknown. The authors present a previously unreported complication of coflex (IPD) placement: the development of a large compressive lumbar synovial cyst...

BACKGROUND AND OBJECTIVE: Spinal degeneration and instability are commonly treated with interbody fusion cages either alone or supplemented with posterior instrumentation with the aim to immobilise the segment and restore intervertebral height. The purpose of this work is to establish a tool which may help to understand the effects of intervertebral cage design and placement on the biomechanical response of a patient-specific model to help reducing post-surgical complications such as subsidence and segment instability...

This paper was aimed to investigate the effects of emodin on oxidative stress and inflammatory response in rats with acute spinal cord injury(SCI), and to explore the protective mechanism of emodin on neurons after SCI. Rat SCI models were established using a modified Allen's method. One hundred and ninety five Sprague-Dawley rats were randomly divded into sham (group A), model (group B), emodin group of 20 mg·kg⁻¹(group C), emodin group of 40 mg·kg⁻¹(group D), emodin group of 80 mg·kg⁻¹(group E)...

Curative effect of posterior lumbar interbody fusion (PLIF) in the treatment of single-segment lumbar degenerative disease and changes in adjacent segment quantitative score was investigated. A total of 86 patients with single-segment lumbar degenerative disease were randomly selected and divided into control group (n=43) and observation group (n=43). The control group was treated with posterolateral lumbar fusion, while the observation group was treated with PLIF. The observation group had a significantly longer operation time and shorter hospitalization time compared with the control group (P<0...

BACKGROUND AND STUDY OBJECTIVE:  Complex traumatic lumbar spine fractures are difficult to manage and typically occur in younger patients. Surgical immobilization for unstable fractures is an accepted treatment but can lead to future adjacent-level disease. Furthermore, large variations in fracture morphology create significant difficulties when attempting fixation. Therefore, a surgical approach that considers both long-term outcomes and fracture type is of utmost importance. We present a novel technique for percutaneous fixation without interbody or posterolateral fusion in a young patient with bilateral pedicle dissociations and an acute-onset incomplete neurologic deficit...

BACKGROUND: Vertebral body (VH) hemangiomas with myelopathy are difficult to manage. OBJECTIVE: To evaluate the role of intra-operative ethanol embolization, surgical decompression and instrumented short segment fusion in VH with myelopathy and long-term outcome (>24 months). METHODS: Prospective study: Symptomatic VH with cord compression with myelopathy. Excluded: pathological fractures, and/or deformity or multi-level pathologies. Surgery consisted of intra-operative bilateral pedicular absolute alcohol (<1% hydrated ethyl alcohol) injection, laminectomy and cord decompression at the level of pathology followed by a short segment instrumented fusion using pedicle screws...

STUDY DESIGN: Bibliometric analysis. OBJECTIVE: To identify, and summarize the key findings of, the top 100 most highly cited works published in spinal disorder topic-specific journals. SUMMARY OF BACKGROUND DATA: There is an abundance of published articles pertaining to spine surgery and spinal disorders. The number of citations a work receives provides a useful measure of its scientific impact. An understanding of the most cited works in spine surgery can identify literature that surgeons and researchers should be familiar with, point to the most active areas of research, inform the design of educational curricula, and help guide future research efforts...

BACKGROUND: We studied the prevalence and treatment outcomes of spondylolisthesis in patients with Loeys-Dietz syndrome (LDS). METHODS: Clinical data and lumbosacral imaging of 138 patients with LDS were reviewed. Spondylolisthesis (L4-L5 or L5-S1) and spondylolysis were characterized by multimodal imaging and correlated with clinical data. Treatments and outcomes were characterized for patients with spondylolisthesis. Associations were determined using the Fisher exact, Mann-Whitney, and Student t tests (α=0...

Adult degenerative scoliosis (ADS) surgery is known for its high incidence of complications. The propose of this study was to determine current complication rates and the predictors of medical complications in surgical ASD patients. A retrospective study of 153 ADS patients who underwent long level spinal fusion with 2-year follow-up between 2012 and 2017. The patient- and surgical-related risk factors for each individual medical complication were identified by using univariate testing. All patients were divided into groups with and without medical complication, infection, neurological complications, and cardiopulmonary complications, respectively...
