Transdural Approach to Resection of Intraspinal Extradural Ventral Cysts in the Lumbar Spine.

Background: Intraspinal extradural ventral cysts in the lumbar spine can cause back pain and neurological deficits of the lower extremities. For the resection of this type of space-occupying lesion, the transdural approach has not been reported in the literature.

Case Description: A 66-year-old man presented, suffering from progressive radiation pain of his bilateral lower extremities.

Risk factors of postoperative low back pain for low-grade isthmic spondylolisthesis: a retrospective study.

Objective: To investigate the risk factors of postoperative low back pain (LBP) following posterior lumbar interbody fusion (PLIF) surgery for low-grade isthmic spondylolisthesis (IS).

Methods: This retrospective study enrolled patients with IS that underwent PLIF between January 2011 and January 2016. Demographic, clinical, surgical and radiological characteristics were analysed to determine associations between these characteristics and LBP as measured using a visual analogue scale (VAS) pain score.

Risk Factors of Postoperative Sacroiliac Joint Pain for Posterior Lumbar Surgery: ≥2-Year Follow-up Retrospective Study.

Purpose: A retrospective study was conducted to clarify the risk factors of postoperative sacroiliac joint pain (SIJP) for posterior open lumbar surgery.

Patients And Methods: A total of 472 patients who underwent posterior lumbar surgery between January 2011 and December 2014 were included in this analysis. We recorded basic characteristics, surgical characteristics, and SIJP information for each patient.

Risk Factors of Postoperative Low Back Pain for Low-Grade Degenerative Spondylolisthesis: An At Least 2-Year Follow-Up Retrospective Study.

Objective: A retrospective study was conducted to clarify the risk factors of postoperative low back pain (LBP) for low-grade degenerative spondylolisthesis.

Patients And Methods: A total of 239 patients who underwent posterior lumbar fusion between January 2011 and January 2015 were included in this analysis. We investigated patient characteristics, surgical characteristics, and radiographic characteristics.

Risk Factors of Postoperative Low Back Pain for Lumbar Spine Disease.

Purpose: A retrospective study was conducted to clarify the risk factors of postoperative low back pain (LBP) for lumbar spine disease.

Patients And Methods: A total of 401 patients who underwent lumbar operation between January 2011 and December 2011 were included in this analysis. We investigated patient characteristics and surgical approaches and also compared the radiographic characteristics.

Predictors of Surgical Outcome in Acute Spinal Cord Injury Patients with Cervical Ossification of the Posterior Longitudinal Ligament.

Objective: A retrospective study was conducted to clarify the predictors of the operation results for ossification of the posterior longitudinal ligament (OPLL) patients with acute spinal cord injury (SCI). Detailed analyses of surgical outcomes of OPLL patients with SCI have been rare because most surveys have aimed to investigate OPLL or SCI, but not both.

Patients And Methods: A total of 36 patients who underwent operation for OPLL between January 2011 and December 2011 were included in this analysis.

Predictors of surgical outcome in ossification of the posterior longitudinal ligament.

Study Design: A retrospective study.

Objective: To clarify the predictors of the operation results for ossification of the posterior longitudinal ligament (OPLL).

Summary Of Background Data: Detailed analyses of surgical outcomes of OPLL have been rare because most survey aimed to investigate cervical spondylotic myelopathy.

[Clinical application of a novel posterior lumbar fusion method and the short-term observation of its effect].

Objective: To increase local blood supply of bone graft, a novel posterior lumbar spine fusion method with orthotopic paraspinal muscle-pediculated bone flaps was constructed, and the fusion rate and clinical effect.were observed.

Methods: From June 2007 to December 2010, 117 patients of lumbar spinal stenosis or lumbar destabilization treated with the novel posterior lumbar fusion method were studied, 49 males and 68 females, aged from 40 to 77 years, average 61.

Aggrecan variable number of tandem repeat polymorphism and lumbar disc degeneration: a meta-analysis.

Study Design: Data on the association between the ACAN (encoded for aggrecan core protein) variable number of tandem repeat (VNTR) polymorphism and lumbar disc degeneration are conflicting, so we performed a meta-analysis.

Objective: Aggrecan is involved in the shock absorbing function of the lumbar disc; we performed a meta-analysis to assess the association between ACAN VNTR and lumbar degeneration.

Summary Of Background Data: To perform a meta-analysis, we searched for studies published until September 2012, using electronic databases (PubMed, EMBASE, and China National Knowledge Infrastructure).

MATN3 gene polymorphism is associated with osteoarthritis in Chinese Han population: a community-based case-control study.

Background: The matrilin, especially matrilin-3 (MATN3), are reported to play important roles in the pathophysiology of osteoarthritis (OA). To explore the relationship between MATN3 SNP6 (rs8176070) and primary OA, we conducted a community-based case-control study.

Methods: A total of 732 community residents aged 40-84 years participated in the community-based study in Northeast China.

Association of ADAMTS5 gene polymorphisms with osteoarthritis in Chinese Han population: a community-based case-control study.

Aggrecanase-2 (ADAMTS5) is reported to play essential roles in the pathophysiology of osteoarthritis (OA). To explore the relationship between ADAMTS5 gene polymorphisms and primary OA, we conducted a community-based case-control study. A total of 732 community residents aged 40-84 years participated in the community-based study in Northeast China.
