BACKGROUND To describe and assess clinical outcomes of the semi-circumferential decompression technique for microsurgical en-bloc total ligamentum flavectomy with preservation of the facet joint to treat the patients who have a lumbar spinal stenosis with degenerative spondylolisthesis. METHODS We retrospectively analyzed the clinical and radiologic outcomes of 19 patients who have a spinal s...

BACKGROUND Pseudomeningocele, an extradural collection of cerebrospinal fluid (CSF), has only been rarely reported to occur spontaneously in conjunction with isthmic spondylolisthesis (with lysis) in the lumbar spine. CASE DESCRIPTION A 68-year-old male presented with low back pain and neurogenic claudication of several years duration without any history of trauma, epidural spine injections, ...

Objective: This retrospective study was designed to make risk assessment of lower-limb DVT in patients with lumbar spondylolisthesis. Methods: Medical records of lumbar spondylolisthesis were retrospectively collected between 01/2014 and 01/2017. Univariate analyses were performed to determine risk factors for DVT. Results: A total of 140 patients were admitted into this study, including 33 mal...

BACKGROUND The role of reduction in the operative management of spondylolisthesis is controversial because of its potential complications, including neurologic deficits, prolonged operative time, and loss of reduction. The aim of this systematic review was to compare arthrodesis in situ and arthrodesis after reduction techniques with respect to clinical and radiographic outcomes and safety. M...

OBJECTIVE The purpose of this study was to evaluate the disability in patients with spondylolisthesis who assigned either to posterolateral fusion (PLF) or posterior lumbar interbody fusion (PLIF) and to compare it between two groups. METHODS In a prospective observational study, 102 surgical candidates with low-grade degenerative and isthmic spondylolisthesis enrolled from 2012 to 2014, and ...

PURPOSE Spondylolysis is known to be a part of a disease process, which describes a defect in the pars interarticularis of vertebra. We aimed to use quantitative computed tomography (QCT) to measure vertebral body bone mineral density (BMD) in patients with lumbar spondylolysis and compare it with readings in controls. METHODS Forty symptomatic patients with lumbar spondylolysis aged 18-52 ye...

PURPOSE To document the occurrence of isolated dorsal subluxation of posterior elements in cases of lumbar spondylolysis without spondylolisthesis both quantitatively (using spinal canal measurements) and qualitatively (by visual inspection) on sagittal MR images. METHODS Retrospective analysis identified 63 patients with lumbar spondylolysis (confirmed by CT or conventional radiography) who ...

STUDY DESIGN  Retrospective cohort study. Clinical question or objective: Is there a benefit to additional transforaminal lumbar interbody fusion (TLIF) if a solid posterolateral (PL) fusion can be achieved with routine bone morphogenetic protein (BMP) use in low-grade spondylolisthesis? METHODS  We performed a retrospective review of patients who had undergone surgery for grade I or II lumba...

STUDY DESIGN  Retrospective cohort study. CLINICAL QUESTION  Do more adult patients affected by low grade isthmic spondylolisthesis have significant clinical and radiological improvement following posterior lumbar interbody fusion (PLIF) than those who receive posterolateral fusion (PLF)? METHODS  One hundred and fourteen patients affected by adult low grade isthmic spondylolisthesis, treat...
