STUDY DESIGN A clinical retrospective study. OBJECTIVE To analyze the complications and relevant management of the correction procedure for focal kyphosis. SUMMARY OF BACKGROUND DATA The treatment of focal kyphosis is a difficult problem in spine surgery. The potential complications of surgery should be considered cautiously and managed positively.

STUDY DESIGN A case-control association study was conducted to investigate the genetic etiology for ossification of the ligamentum flavum (OLF) and ossification of the posterior longitudinal ligament of the spine (OPLL). OBJECTIVE To determine whether COL6A1 polymorphisms are associated with susceptibility to OLF and OPLL in Chinese Han population. (More)
STUDY DESIGN Retrospective and radiological analysis of spinopelvic sagittal alignment in Chinese patients with thoracic and thoracolumbar kyphosis. OBJECTIVE To determine the impact of thoracic and thoracolumbar kyphosis on pelvic sagittal morphology and the mechanisms of adjusting trunk sagittal balance. SUMMARY OF BACKGROUND DATA Previous studies(More)
OBJECTIVE To study the risk factors for deep surgical site infection after posterior thoracic and lumbar surgery. METHODS The medical data of the patients with deep surgical site infection after posterior thoracic and lumbar surgery from January 2008 to December 2013 were reviewed.For each case patient, 3 non-infected controls were randomly selected from(More)
PURPOSE The purpose of this study is to review our operative experience of congenital kyphosis or kyphoscoliosis undergoing either pedicle subtraction osteotomy (PSO) or posterior vertebral column resection (pVCR) according to certain criteria we have established. METHODS From December 2003 to 2009, 23 consecutive patients of congenital kyphosis or(More)
PURPOSE Symptomatic disc herniations in the thoracolumbar spine between T10/11 and L1/2 can be collectively called thoracolumbar disc herniation (TLDH). The etiology of this disorder is unclear. However, it is interesting that we have noted numerous TLDH patients have radiographic features of another spinal disorder which is Scheuermann's disease (SD). The(More)
BACKGROUND Lumbar disk herniation in adults is thought to be caused by repetitive overloading and age-rated degenerative changes. However, these causes are absent in children and adolescent patients. We assume that structural malformations in the lumbar spine could predispose intervertebral disks to early degeneration and hence need to be surgically fused.(More)
STUDY DESIGN Retrospective review. OBJECTIVE To perform a single-institution analysis of incidence, treatment, and clinical outcome in patients with thoracic ossification of the ligamentum flavum (OLF) who experienced dural tears and cerebrospinal fluid (CSF) leakage. SUMMARY OF BACKGROUND DATA There is a paucity of clinical reports focusing on dural(More)
OBJECT In this paper, the authors aimed to summarize the clinical characteristics of ossification of the ligamentum flavum (OLF) associated with dural ossification (DO) and to identify improved methods for preoperative diagnosis. METHODS Thirty-six patients who had undergone OLF surgery between February 2005 and September 2009 were included in this(More)
OBJECTIVE To evaluate the feasibility, safety and efficacy of surgical correction of thoracolumbar kyphosis, using the new type spinal osteotomy with cage inserting into the intervertebral gap anteriorly and closing posteriorly by a single posterior approach. METHODS Since 2003, eight consecutive patients with thoracolumbar kyphosis were treated(More)
