Grassland humus forms have been investigated morphologically in the field and with the microscope (Barratt 1960, 1964). They are divisible into two main groups: mulls and mors. In mulls, organic residues are finely conllninuted and intimately mixed with the colloidal-sized fraction of the mineral soil. In mors, organic residues accumulate predominantly above the mineral soil surface, but show p...

BACKGROUND Investigating Health Related Quality of Life (HRQL) is considered determinant in patients with Adolescent Idiopathic Scoliosis (AIS) in clinical as in research field. The aim of the present study is to explore the most relevant aspects of personality of the patients with AIS and its relationship with HRQL. METHOD 50 patients (mean age = 16 years) were given a socio-demographic data...

T he effectiveness of brace treatment for scoliosis was controversial until recently. Brace treatment had not been proven to prevent progression of the scoliotic curve. 1 There had been no standardized study of this issue, and there were no significant differences among the types of braces used. 1 The unwillingness of children to wear braces raised concern, especially among physicians, about wh...

BACKGROUND The Lyon brace is commonly prescribed in many European countries to patients with thoracic curves and is based on the three-point pressure system. The purpose of this study was to evaluate the efficacy of Lyon bracing for the conservative treatment of adolescent females with idiopathic thoracic curves in a case series selected on the basis of the Scoliosis Research Society (SRS) Comm...

STUDY DESIGN Thirty-seven patients who experienced visual loss after spine surgery were identified through a survey of the members of the Scoliosis Research Society and a review of the recent literature. OBJECTIVES Records were reviewed in an attempt to identify preoperative and intraoperative risk factors and to assess the likelihood of recovery. SUMMARY OF BACKGROUND DATA Postoperative bl...

Background and Aim: Neurofibromatosis-1(NF-1) is a common genetic condition in children. It is becoming increasingly recognized that in neurofibromatosis, there might be anomalous development of bone with or without any local anomaly of neuro-ectodermal basis. This review was conducted to highlight the different features of spinal disorders in this congenital disease. Methods and Materials: Di...

This Editorial initiates a Thematic Series on the aetiology, pathogenesis and pathomechanisms (scoliogeny) of adolescent idiopathic scoliosis (AIS). It introduces the Series and invites contributions from researchers in the field and from interested parties. The aim is to develop a wideranging online discussion based on evidence and theoretical interpretations, In doing this, it will extend the...

Congenital scoliosis is an abnormal lateral curvature of the spine, resulting from disruption of normal vertebral development. Although there are many types of defects observed in congenital scoliosis, all result from abnormal formation and segmentation of the vertebral precursors, called somites. Developmental studies in animal models have identified many genes regulating somite formation and ...

The purpose of this prospective observational study was to evaluate the effectiveness of the Dynamic SpineCor System for adolescent idiopathic scoliosis in accordance with the standardized outcome criteria proposed by the Scoliosis Research Society Committee on Bracing and Nonoperative Management. The SpineCor System is the first and only truly dynamic brace, which provides a progressive correc...

This guideline has been discussed by the SOSORT guideline committee prior to the SOSORT consensus meeting in Milan, January 2005 and published in its first version on the SOSORT homepage: http://www.sosort.org/meetings.php. After the meeting it again has been discussed by the members of the SOSORT guideline committee to establish the final 2005 version submitted to Scoliosis, the official Journ...
