OBJECTIVE To evaluate the effectiveness of the In- space (Synthes, Umkirch, Germany) and the correlation between radiographic parameters and clinical outcome in patients with lumbar spinal canal stenosis (LSS). METHODS Between June 2009 and May 2013, 56 patients with LSS underwent In-space by one senior surgeon. All of the patients were evaluated both clinically and radiographic measurements ...

INTRODUCTION Achondroplasia is a genetic disorder of bone growth. Congenital spinal stenosis is a well-known complication of this disease, but, to the best of our knowledge, no cases involving combined stenosis with congenital lumbar spinal stenosis and ossification of the ligamentum flavum in achondroplasia have been reported previously. In this report, we describe a case of a patient with con...

OBJECTIVES Pedicle-lengthening osteotomy is a novel surgery for lumbar spinal stenosis (LSS), which achieves substantial enlargement of the spinal canal by expansion of the bilateral pedicle osteotomy sites. Few studies have evaluated the impact of this new surgery on spinal canal volume (SCV) and neural foramen dimension (NFD) in three different types of LSS patients. METHODS CT scans were p...

We describe a rare case of lumbar spinal stenosis due to a large calcified mass in the ligamentum flavum. This patient presented with a 12-month history of severe right leg pain and intermittent claudication. A computed tomography scan was performed, revealing a large calcified mass on the ligamentum flavum at the right-hand side of the lumbar spinal canal. We performed a laminotomy at the L4/5...

Background: The incidence of cervical, thoracic and lumbar spinal canal stenosis is low. It difficult to identify the main focus responsible segment, it also select sequence staging surgery. We report a patient with triple stenosis. Case Presentation: In this paper, we introduced 61-year-old female who had previously undergone “lumbar discectomy” in outer hospital. postoperative effect was not ...

The authors have made a retrospective study of a cohort of patients who underwent surgery for spinal stenosis. A total of 85 patients were surgically treated for spinal stenosis between 1993 and 1997, and 79 patients were available for re-evaluation. The average time of follow-up was 79 months. Twenty patients with monosegmental stenosis underwent fenestration and undercutting, 16 patients had ...

Degeneration of the intervertebral disc results in initial relative instability, hypermobility, and hypertrophy of the facet joints, particularly at the superior articular process. This finally leads to a reduction of the spinal canal dimensions and compression of the neural elements, which can result in neurogenic intermittent claudication caused by venous congestion and arterial hypertension ...

BACKGROUND The study of lumbar spine pathology requires adequate preparation and knowledge of the normal structure of this part of the spine. The main goal of the study was to assess spinal canal morphology with computed tomography. The sagittal and interpedicular dimensions and surface area were considered the most important measurements. An additional goal was to assess the shape of the spina...

OBJECTIVE To study the effectiveness of electroacupuncture of the spinal nerve root using a selective spinal nerve block technique for the treatment of lumbar and lower limb symptoms in patients with lumbar spinal canal stenosis. METHODS Subjects were 17 patients with spinal canal stenosis who did not respond to 2 months of general conservative treatment and conventional acupuncture. Under x-...

STUDY DESIGN A retrospective study. PURPOSE To examine the effectiveness of using an electrodiagnostic technique as a new approach in the clinical diagnosis of extraforaminal stenosis at L5-S1. OVERVIEW OF LITERATURE We introduced a new effective approach to the diagnosis of extraforaminal stenosis at the lumbosacral junction using the existing electrophysiological evaluation technique. M...
