Treatment of early-onset scoliosis with growing rods in patients with neurofibromatosis-1

This study aimed at verifying the efficacy of growing rod treatment in patients affected by neurofibromatosis with early-onset scoliosis. The authors present a retrospective case study of seven children treated between 2001 and 2017. Mean age at initial surgery was 7.2 years. Mean Cobb angle was 82.7°. Lengthening was performed once a year. Mean Cobb angle at last follow-up was 50.1°. Mean spinal growth was 13.6 mm/year, with regular gain during lengthening procedures. Mean follow-up period was 7 years after the first surgery. Three patients underwent final fusion. Complications were one proximal junctional kyphosis, nine rod breakages, and one hook dislocation.

We report a 17-year-old boy affected by NF1 with extreme severe spinal and thoracic malformations affecting bone and lung tissues, including hypoplasia of the right lung, unilateral costal agenesis and severe dystrophic scoliosis characterized by association of hemivertebra, fusion of adjacent vertebral bodies and defective pedicles. At birth, he presented an acute respiratory distress requiring invasive ventilator support. The diagnosis of NF1 was confirmed at age 5 by the identification of a de novo heterozygous mutation c.4537C > T, p.Arg1513* in NF1. Trio-based Whole Exome Sequencing (WES) was performed to...

Rationale: Bone malformation occurs in 10% to 25% neurofibromatosis type 1 (NF-1) patients, and the manifestations are scoliosis, congenital arch and pseudo-joint formation, bone cyst, and pathologic fracture. However, a large segmental defect without obvious signs of bone destruction has rarely been reported. Patient concerns: A 4.5-year-old male presented with a 4-year history of shortening of the right upper limb and radial head dislocation. The X-ray indicated a lack of the distal part of the right ulna and radial head dislocation. Diagnosis: The X-ray showed obvious bone resorption at the right ulna distal, pr...

Katie Krzyzanowski was born with neurofibromatosis, which causes tumours to form on nerve endings. This led the now 20-year-old, of Somerset, to develop scoliosis at four years old.

Rationale: Scoliosis is the most common form of dystrophic spinal deformities in type 1 neurofibromatosis, whereas a spontaneous rotational dislocation of the lumbar spine is a rare entity. Former researchers had advocated the use of circumferential fusion performed through combined anterior-posterior approaches as the mode of treatment of this situation, but we managed to achieve a solid circumferential fusion equally using posterior approach alone. Patient concerns: A 51-year-old lady presented with severe back pain and no history of trauma, fever, or loss of weight. On examination, she showed several café-au...

Abstract OBJECTIVE: The aim of this study was to evaluate the differences in transcranial electric motor-evoked potentials - TceMEP on upper limbs and the incidences of postoperative brachial plexopathy between patients with kyphotic and scoliotic trunk shapes. METHODS: In the period of January 2011-January 2017, 61 consecutive patients (mean age: 18.4 years ± 4.4 years (range: 10-32)) with pediatric spinal deformity underwent surgery in our Department. Eight of them had a kyphotic trunk deformity (Scheuermann kyphosis, neurofibromatosis, posterior thoracic hemivertebra), and the rest of the ...

AbstractScoliosis is a common manifestation of neurofibromatosis type 1, causing significant morbidity. The etiology of dystrophic scoliosis in neurofibromatosis type 1 is not fully understood and therapies are lacking. Somatic mutations inNF1 have been shown in tibial pseudarthrosis providing rationale for similar processes in neurofibromatosis type 1 –associated dystrophic scoliosis. Spinal samples from surgical procedures with matched peripheral blood of two individuals with neurofibromatosis type 1 and dystrophic scoliosis were obtained and DNA extracted. Next generation sequencing of various spinal sections as w...

Study Design: This is a retrospective cohort study. Objective: To investigate surgical outcomes and instrumentation-related complications (IRCs) of dystrophic scoliosis associated with neurofibromatosis type 1 (NF-1). Summary of Background Data: Surgical management, including the growing rod technique and early definitive fusion, has been recommended to avoid progression of NF-1 scoliosis. However, no study has investigated the outcomes and complications of different surgical interventions. Materials and Methods: We performed a retrospective review of a cohort of 59 patients diagnosed with NF-1 dystrophic scolio...

Study Design. Retrospective cohort study. Objective. To assess the incidence and risk factors of instrumentation-related complication (IRC) in pediatric patients surgically treated for neurofibromatosis type 1 (NF-1) dystrophic scoliosis. Summary of Background Data. Surgical management including growing rods technique and early definitive fusion has been recommended to avoid progression of NF-1 scoliosis. However, no study has yet investigated the incidence and risk factors of IRC in these surgical interventions. Methods. Data of 59 pediatric NF-1 patients who had been surgically treated for dystrophic scoliosis...

The librettos of several of the most famous Romantic operas contain references to disease. These operas can serve as valuable sources of information regarding how spinal deformities were understood during the nineteenth century by physicians and lay persons alike. Original librettos of the operas “Rigoletto” (1851) by Giuseppe Verdi (1813–1901) and “La Esmeralda” (1836) by Louise Bertin (1805–1877) were analyzed. In both operas, spinal deformities of Rigoletto and Quasimodo are a central issue. In detail, Quasimodo could suffer from von Recklinghausen's neurofibromatosis, while Rigoletto...
