Impact of the Choice of the Distal Vertebral in the Surgery of the Thoracic Adolescent Idiopathic Scoliosis

2016-06-07 16:08:21 | BioPortfolio

Summary

The problem of choosing the supporting vertebra was the subject of several studies. They do not suggest as regards the techniques that are not currently used or with insufficient setback.

The need to have a sufficient number of files with a minimum decline of 5 years for proposing a multicenter study that will be conducted within the framework of the Scoliosis Research Group (SRG) and will result in a roundtable at the next congress GES in March 2015. the GES gathers most of the teams that support this pathology.

Description

Idiopathic scoliosis is a deformity in three planes of space the child's spine and scalable teenager with growth. In adults is causing severe deformities of respiratory failure responsible and disabling back pain. Scoliosis is most often idiopathic without cause found that the genetic origin is being identified. It is detected by the school doctor, the doctor or pediatrician. The management is based primarily on monitoring small angle discoveries scoliosis and the orthopedic treatment of progressive scoliosis by the specialized services of pediatric orthopedics or rehabilitation as recommended by the HAS (February 2008). Surgical treatment is reserved for the orthopedic treatment failures or advanced scoliosis discovered too late.

The goal of surgery is to reduce as much as possible distortion in the three planes of space and avoid the progression of the deformity in adulthood. Its principle is to correct the deformity using instrumentation and maintain over time this correction with a bone graft. This is commonly called spinal fusion with instrumentation. The instrumentation includes all of the vertebral anchors connected to rods.

Indications are asked in each case most often in adolescence and sometimes in younger children and rarely in adulthood. The procedure performed in adolescence allows to benefit from a flexible spine still allowing good reduction of the deformation, a lesser neurological risk and good consolidation of the bony fusion guarantees a stable income in the long term.

Among all types of curves, thoracic scoliosis pose the problem of choosing the bends to be instrumented. This choice is an essential element for the initial correction and become the long-term. It is the result of a compromise between a long instrumentation that orchestrates all of the deformation to the detriment of the mobility of the lumbar spine and a shorter instrumentation that preserves mobility at the expense perhaps of a smaller reduction. These short instrumentations called selective thoracic instrumentation, the choice of the support or lower vertebra vertebra of instrumentation is an unsolved problem and is the subject of this work.

The immediate results of the posterior vertebral arthrodesis are assessed by the correction of the deformity in three planes of space: measuring the angle of the curvature in the coronal plane, analyzing the return of a physiological kyphosis in sagittal plane and correction of the vertebral rotation in the horizontal plane. The results for medium and long term are assessed by analyzing the maintenance of correction of the deformity and the evolution of the above spine and above underlying arthrodesis. This is appreciated by the coronal and sagittal balance, changing the supporting vertebra and the first non-instrumented vertebra and evolution spine underlying uninstrumented.

The problem of choosing the supporting vertebra was the subject of several studies. They do not suggest as regards the techniques that are not currently used or with insufficient setback.

An appreciable lateral deviation in the normally straight vertical line of the spine. (Dorland, 27th ed)

Deformities of the SPINE characterized by abnormal bending or flexure in the vertebral column. They may be bending forward (KYPHOSIS), backward (LORDOSIS), or sideway (SCOLIOSIS).

Congenital or postnatal overgrowth syndrome most often in height and occipitofrontal circumference with variable delayed motor and cognitive development. Other associated features include advanced bone age, seizures, NEONATAL JAUNDICE; HYPOTONIA; and SCOLIOSIS. It is also associated with increased risk of developing neoplasms in adulthood. Mutations in the NSD1 protein and its HAPLOINSUFFICIENCY are associated with the syndrome.

A form of inherited long QT syndrome (or LQT7) that is characterized by a triad of potassium-sensitive periodic paralysis, VENTRICULAR ECTOPIC BEATS, and abnormal features such as short stature, low-set ears, and SCOLIOSIS. It results from mutations of KCNJ2 gene which encodes a channel protein (INWARD RECTIFIER POTASSIUM CHANNELS) that regulates resting membrane potential.

Autosomal recessive inborn error of methionine metabolism usually caused by a deficiency of CYSTATHIONINE BETA-SYNTHASE and associated with elevations of homocysteine in plasma and urine. Clinical features include a tall slender habitus, SCOLIOSIS, arachnodactyly, MUSCLE WEAKNESS, genu varus, thin blond hair, malar flush, lens dislocations, an increased incidence of MENTAL RETARDATION, and a tendency to develop fibrosis of arteries, frequently complicated by CEREBROVASCULAR ACCIDENTS and MYOCARDIAL INFARCTION.
