Multisegmental Lumbar Corporectomy and Transcorporal Fixation for Correction of Extreme Thoracolumbar Kyphosis in Myelomeningocele with Chronic Decubitus

We introduce a novel technique for the treatment of severe kyphosis in myelomeningocele. A 5-year-old paraplegic boy with myelomeningocele presented with severe thoracolumbar kyphosis and a chronic ulcus at the site of the gibbus. The myelomeningocele had been treated during his first week of life, and an accompanying Chiari type II malformation had been treated by ventriculoperitoneal shunting. He subsequently developed a rapidly progressive thoracolumbar kyphosis with an angle of 180 ° between T10 and L5. He also suffered from a chronic superinfected skin ulcus at the site of the gibbus. Since the skin ulcus required plastic surgery reconstruction, we deemed classical posterior fixation after kyphectomy unfeasible. The subsequent operative steps of our novel surgical approach w ere performed in a single-stage surgery. First, a three-level lumbar corporectomy from L1 to L3 was performed. Subsequently, the body of the removed L2 vertebra was isolated and configured as an autologous graft to bridge the gap between the thoracic and the caudal lumbar spine. The graft was fixed via a transcorporal interbody fusion technique with titanium screws, and chopped autologous bone was added for fusion. The skin was closed using rotation flaps. At the 3-year follow-up, the patient and his family reported marked improvement of quality of life, imaging showed solid fusion and the wou nd was unremarkable. Our novel technique with transcorporal fixation provides new perspectives in the tr...

Authors: Hadden K, Gan JM, McClure S, McCarthy RE, Bumpass DB Abstract The Scoliosis Research Society Questionnaire (SRS30) was designed to measure healthrelated quality of life in scoliosis patients. Patients with low health literacy may need specific guidance when providing feedback on the SRS30 so that reliable and valid results are collected for clinical decision making. The purpose of this research study was to investigate the health literacy demands of the Scoliosis Research Society Questionnaire (SRS30) and to determine if health literacy best practices mitigate errors for patients with low health literacy. ...

Authors: Smith EJ, Inkrott BP, Kim CY, Du JY, Ahn UM, Ahn NU Abstract The prevalence of obesity has been rising, creating a major public health concern. While several studies have shown obesity to increase the risk of surgical complications, few have analyzed its effects on reoperation, specifically after singlelevel lumbar discectomy. Data was obtained using the commercially available Explorys software that houses deidentified data for several major healthcare systems. A database search was used to find all patients who had undergone a lumbar discectomy. Scoliosis, spondylolisthesis, smoking history and depression...

ConclusionBased on these findings, the primary goal of scoliosis correction should focus on minimizing lateral translation rather than eliminating axial rotation. Knowing the IVR in the axial plane helps accurately determine the limits of the structural curves. VV-based axial views can facilitate the accurate determination of the end vertebrae and selection of the appropriate correction technique of the curve.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

ConclusionPI spontaneously increases in elderly ASD patients with severe sagittal deformity after long fusion to sacrum, while is relative invariable in those with minor sagittal deformity. Variation in PI could be considered as a secondary change compensating for the spinal sagittal malalignment under long spinal fusion in elderly patients.

Diagnosing pneumonia and other lung conditions can be challenging in patients with severe intellectual or physical disabilities or severe chest deformities. Physical examination is sometimes difficult to perform and the frequently requested chest x-ray (CXR) study is often of little value in the diagnostic approach to this population. Point-of-care lung ultrasound (US) is an emerging diagnostic tool with particularly high level of accuracy in detecting pneumonia, pleural effusion, and pneumothorax.

In this study, zebrafish (Danio rerio) were exposed to different concentrations of THC (0.08, 0.4, 2  μM) during embryonic-larval development and the effects on aging were measured 30 months later and in the offspring of the exposed fish (F1 generation). Exposure to 0.08 μM THC resulted in increased male survival at 30 months of age. As the concentration of THC increased, this protective effe ct was lost. Treatment with the lowest concentration of THC also significantly increased egg production, while higher concentrations resulted in impaired fecundity. Treatment with the lowest dose of THC signi...

Conclusions: Carrying a load on the head leads to accelerated degenerative changes, which involve the upper cervical spine more than the lower cervical spine and predisposes it to injury at a lower threshold. Thus, alternative methods of carrying loads should be proposed. PMID: 32213796 [PubMed - as supplied by publisher]
