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 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 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 determine the effectiveness of surgical correction for post-traumatic kyphosis of thoracolumbar spine. METHODS From 1996 to 2003, 33 consecutive patients with post-traumatic kyphosis of thoracolumbar spine were corrected surgically. The mean age was 40.3 years (range, 13 - 65 years). The mean time between the initial injury and surgical(More)
OBJECTIVES To analyze the clinical characteristics and surgical results of posttraumatic kyphosis of the thoracolumbar segment. METHODS Thirty-four patients with posttraumatic kyphosis of the thoracolumbar segment underwent posterior osteotomy, kyphosis correction, and fixation at our hospital. The kyphosis apex was from T10 to L2. There were 15 male and(More)
OBJECTIVES To investigate the long-term surgical outcome of thoracic myelopathy caused by the ossification of the ligamentum flavum (OLF) and evaluate the related risk factors. METHODS Forty-four patients who underwent decompressive laminectomy with thoracic OLF between January 1990 and December 2005 and got more than 5 years follow-up were(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)
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)
OBJECT The object of this study was to compare the clinical and radiographic outcomes of 36 patients with posttuberculosis kyphosis who underwent one of two types of osteotomy. METHODS Each patient underwent single-stage correction via a posterior surgical approach. A modified pedicle subtraction osteotomy (mPSO) was performed when the kyphotic deformity(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)
