The construction of the scoliosis 3D finite element model and the biomechanical analysis of PVCR orthopaedy

Conclusion: The 3D finite element model based on 3D finite element software was highly efficient, and its numerical simulation was accurate, which was important for the subsequent biomechanical analysis of PVCR orthopaedy. In addition, the vertebral stress of PVCR orthopaedy was different in each body part, which was mainly affected by the applied orthodontic force and the sites of the orthodontic area.

Publication date: June 2020Source: Interdisciplinary Neurosurgery, Volume 20Author(s): Adrian Kelly, Aftab Younus, Patrick LekgwaraAbstractAdult scoliosis is an umbrella term referring to all forms of scoliosis occurring in skeletally mature individuals, irrespective of whether the deformity began before or after skeletal maturity. Adult degenerative scoliosis is a specific type of adult scoliosis that refers to a structural curve that develops after skeletal maturity in a previously normal spine. The pathogenesis of adult degenerative scoliosis has at its foundation the same starting point of degenerative spine disease na...

ConclusionsBoth distal radius and ulna scores correlate with the longitudinal growth potential, and thus, the DRU scoring scheme is an alternative predictor for growth potential and curve progression in girls with IS.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

Conclusions: Given the importance of accuracy in height measures to evaluate infant health, it is crucial to carry out more researches in order to safely establish an association between both estimate and real statures. The development of anthropometric protocols, emerged from such researches, would benefit the follow-up of children with severe psychomotor disabilities.RESUMO Objetivo: Revisar estudos que avaliam correspond ência entre a altura estimada por medidas segmentares e a estatura real de crianças com paralisia cerebral. Fonte de dados: Revisão sistemática da literatura entre 1995 e 2018...

This study aimed to develop a risk score based on 5-year-old children with CP to predict the risk of scoliosis before the age of 16.Patients and methods - This prospective registry study included 654 children with CP in Sweden born in 2000 to 2003 and registered with the Swedish CP follow-up program (CPUP) at the age of 5 years, including all Gross Motor Function Classification System (GMFCS) levels. 92 children developed a scoliosis before the age of 16 years. Univariable and multivariable logistic regressions were used to analyze 8 potential predictors for scoliosis: GMFCS, sex, spastic subtype, epilepsy, hip surgery, mi...

This report presents the case of a 35-year-old woman with PRS and scoliosis. Among the syndromes related to PRS, cerebro-costo-mandibular syndrome (CCMS), which is characterized by posterior rib gap defects and vertebral anomalies, was suspected in this patient. However, no posterior rib gap defect was detected on radiological examinations. Although over 80 cases of CCMS have been reported to date, few cases of PRS with scoliosis alone have been reported. Therefore, this report demonstrated the clinical, radiological, and cephalometric characteristics of an adult patient with PRS and scoliosis, but without rib anomalies. ...

This study reports on the indications, surgical technique and results using pedicle screw instrumentation exclusively with or without pelvic fixation for spine fusion in patients with NMS.Patients and methodsThirty-seven NMS patients were treated with pedicle screw instrumentation (PSI) between 2007 and 2013 with a minimum follow-up of 24 months. The mean age at the time of operation was 14.91 ± 2.03 years (range, 11.17–18.58). Posterior spine fusion (PSF) was conducted in 33 patients; 4 patients underwent a combined anterior spinal release followed by PSF during one-stage surgery. Pelvic fixation wa...

This study seeks to evaluate the likelihood of screw misplacement at the end vertebra and apex. Methods: A retrospective review of preoperative and postoperative computed tomographic (CT) scans of spinal deformity patients who underwent posterior spinal fusion with pedicle screw constructs between 2004 and 2011 was performed. Pedicles located at the upper instrumented vertebra (UIV) and lower instrumented vertebra (LIV), and the major and minor apices were evaluated. Pedicle morphology was studied on preoperative CT and screw placement on postoperative CT. Results: In total, 188 patients met the inclusion criteria, 1...
