Pediatric spinal trauma can present a surgeon with difficult management decisions given the rarity of these cases, pediatric anatomy, and a growing spine. The need to stabilize a traumatically unstable pediatric spine can be an operative challenge given the lack of instrumentation available. The authors present a surgical technique and an illustrative case that may offer a novel, less disruptive method of stabilization. A 2-year-old girl presented after an assault with an L1-2 fracture subluxation with lateral listhesis and fractured jumped facets exhibited on CT scans...

BACKGROUND: Axis (C2) screw fixation has been shown to be effective in treating disorders that necessitate cervical stabilization. Although translaminar C2 screws have demonstrated clinical efficacy in adults, this technique has not yet been thoroughly investigated in children. This study describes the indications, technique, and results of translaminar C2 screw fixation in a case series of pediatric cervical spine disorders. METHODS: We searched the orthopaedic database at our institution for patients who had undergone a cervical spinal fusion that encompassed C2 between 2007 and 2017...

OBJECTIVE Spinal osteotomy in pediatric patients is challenging due to various factors. For correction of severe rigid kyphoscoliosis in children, numerous techniques with anterior or posterior or combined approaches, as well as multilevel osteotomies, have been described. These techniques are associated with prolonged operative times and large amounts of blood loss. The purpose of this study was to evaluate the clinical and radiologically confirmed efficacy of a modification of the apical spinal osteotomy (ASO) technique-posterior-only single-level asymmetric closing osteotomy-in pediatric patients with severe rigid kyphoscoliosis...

Arthrogryposis multiplex congenita is a rare, nonprogressive congenital disorder that describes a constellation of conditions characterized by multiple joint contractures. Spinal pathology and deformity are common; however, the majority of the literature on arthrogryposis is focused on pediatric management. There exist very few reports on long-term outcomes and management of adults with arthrogryposis. We present a case of cervical spinal stenosis in an adult female with arthrogryposis that underwent posterior cervical decompression and fusion...

OBJECTIVE Split laminotomy is a technique for accessing the spinal canal from the posterior midline that minimizes muscle dissection and bone removal. Benefits of this approach in minimizing postoperative pain and muscle atrophy in the adult population have been reported, but pediatric data are limited. Herein, the authors evaluate the benefits of the split laminotomy technique in pediatric patients. METHODS Data obtained in patients who underwent posterior spine surgery at Children's Hospital of Wisconsin for an intradural midline pathology between April 2008 and June 2015 were reviewed retrospectively...

Finite element (FE) models are a powerful tool that can be used to understand injury mechanisms and develop better safety systems. This study aims to extend the understanding of pediatric spine biomechanics, where there is a paucity of studies available. A newly developed and continuously scalable FE model was validated and scaled to 1.5-, 3-, 6-, 10-, 14- and 18-year-old using a non-linear scaling technique, accounting for local topological changes. The oldest and youngest ages were also scaled using homogeneous geometric scaling...

BACKGROUND: Ehler-Danlos syndome (EDS) refers to a group of heritable connective tissue disorders; rare manifestations of which are cervical kyphosis and clinical myelopathy. Surgical treatment is described for the deformity in the thoracolumbar spine in adolescents but not for infantile cervical spine. Internal fixation for deformity correction in the infantile cervical spine is challenging due to the diminutive size of the bony anatomy and the lack of spinal instrumentation specifically designed for young children...

We conducted a systematic review with meta-analysis and qualitative synthesis. This study aims to characterize pseudarthrosis after long-segment fusion in spinal deformity by identifying incidence rates by etiology, risk factors for its development, and common features. Pseudarthrosis can be a painful and debilitating complication of spinal fusion that may require reoperation. It is poorly characterized in the setting of spinal deformity. The MEDLINE, EMBASE, and Cochrane databases were searched for clinical research including spinal deformity patients treated with long-segment fusions reporting pseudarthrosis as a complication...

Spinal muscular atrophy (SMAs) is a group of rare autosomal recessive diseases in which there is degeneration of alpha motor neurons in the spinal cord leading to progressive distal motor weakness. Here we report a case of type 0 SMA in a female neonate born at the Department of Pediatrics, PGIMS, Rohtak (Haryana) India, associated with generalized osteopenia and bony deformity in form of unilateral club foot. It may be emphasized that diagnosis of SMA should be kept in mind as a differential in cases of unexplained severe generalized hypotonia and severe respiratory compromise immediately after birth...

CASE: A spinal deformity with wedging of L5 and rounding of the surface of the sacral dome is very common in pediatric patients with spondylolisthesis at the L5 vertebral level, and it has been well documented that severe spondylolisthesis is a good indication for spinal arthrodesis. We report the natural correction and adaptation of a severely deformed sacral dome with slippage (40.8%) in a pediatric patient with nonoperative treatment. CONCLUSION: Vertebral deformity in children can be reversible...

Evaluation of pediatric spinal deformity requires knowledge of special orthopaedic testing and radiographic interpretation. The determination of recommendations for treatment of spinal abnormalities in children can be challenging and at times complex, as treatment options are dependent upon a variety of factors. The etiology of scoliosis or kyphosis, presence or absence of vertebral anomalies, symptoms, magnitude of the curve, physiologic/skeletal age, and evidence of and risk of progression all require consideration and play a role in the shared decision-making process...
