Safety and efficacy of posterior approach for resection of spinal meningioma: Impact of dural attachment location.

Background: Spinal meningiomas (SMs) are common benign tumors that are typically treated with surgical resection. The choice of surgical approach may vary depending on the location of dural attachment of the SM, with a posterior approach being the traditional preference. However, there is limited research available on the impact of dural attachment location on outcomes following posterior approach for SM resection.

Lateral Fusion is a Unique Feature in Oblique Lumbar Interbody Fusion Surgery: A Retrospective Cohort Study.

Study Design: Retrospective cohort study.

Objective: Limited clinical literature addresses potential differences in fusion features between Oblique lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF). We observed that in OLIF, there are many cases with the appearance of extra-vertebral bone bridges (EVB), a phenomenon distinct from traditional TLIF fusion.

Lumbar foraminal stenosis was associated with back pain and leg pain: epidemiological evidence from a population-based cohort.

Objectives: To determine the characteristics of lumbar foraminal stenosis (LFS) on magnetic resonance (MR) images and their association with back pain and radiating leg pain in a population-based sample of Chinese subjects.

Methods: This study was an extension of the Hangzhou Lumbar Spine Study, a cross-sectional study focusing on back pain and lumbar spine MR imaging findings. Questionnaire data, including demographics, lifestyle, occupational exposures, back pain and radiating leg pain were included.

Valproic acid accelerates skin wound healing in mice via its anti-inflammatory and apoptotic cell clearance-promoting effects.

Objective: To investigate the effects of valproic acid (VPA) on skin wound healing in mice.

Methods: Full-thickness wounds were created in mice, and then VPA was applied. The wound areas were quantified daily.

Conservative Treatments for Lumbar Disc Herniation at L3-4 or L4-5 Were More Likely to Fail When Ipsilateral Foraminal Stenosis Was Present at the Caudally Adjacent Segment.

Background: Conservative treatments are important in lumbar disc herniation (LDH), but predictors for poor outcomes are unclear.

Methods: Consecutive patients with unilateral single-level LDH at L3-4 or L4-5 were enrolled. Baseline clinical data were collected, and lumbar spine magnetic resonance imaging was evaluated.

[Bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach for osteoporotic vertebral compression fracture of lumbar].

Objective: To evaluate the feasibility and short-term effectiveness of bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach for osteoporotic vertebral compression fracture (OVCF) of lumbar.

Methods: A retrospective analysis was made on the clinical data of 93 patients with OVCF of lumbar who met the selection criteria between January 2018 and June 2019. According to the different surgical methods, they were divided into group A (44 cases, treated with bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach) and group B [49 cases, treated with percutaneous kyphoplasty (PKP) via bilateral transpedicle approach].

[Short-term effectiveness of polyaxial locking plate for fixation of femoral neck fracture in middle-aged and elderly patients].

Objective: To evaluate the feasibility and short-term effectiveness of polyaxial locking plate for fixation of femoral neck fracture in the middle-aged and elderly patients.

Methods: A retrospective analysis was made on the clinical data of 13 patients with femoral neck fracture undergoing fixation with polyaxial locking plates between September 2013 and June 2015 (group A) and 13 patients with femoral neck fracture undergoing fixation with three cannulated screws in the same period (group B). There was no significant difference in gender, age, side, cause of injury, Garden type, type of fracture position, type of Pauwels angle, Singh index, time between injury and operation, and preoperative complications between 2 groups ( >0.

Experience with the second-generation Wallis interspinous dynamic stabilization device implanted in degenerative lumbar disease: a case series of 50 patients.

Aim: This study aimed to evaluate the short- to medium-term outcomes of the second-generation Wallis interspinous dynamic stabilization device for treatment of lumbar degenerative disease.

Material And Methods: Fifty patients with lumbar degenerative disease treated from August 2007 to September 2009 were included in this retrospective study. The Japanese Orthopedic Association (JOA) score and the Oswestry Disability Index (ODI) were used for therapeutic efficacy evaluation.

[Clinical analysis of an interspinous stabilization system (wallis) in treating lumbar degenerative disease].

Objective: To evaluate clinical results of an interspinous stabilization system (Wallis) in treating lumbar degenerative disease in the short-term.

Methods: From August 2007 to June 2010,48 patients with lumbar degenerative disease who were treated with interspinous stabilization system, the data of patients were analyzed retrospectively. In all of the 48 cases, there were 30 males and 18 females with an average age of 54.
