RATIONALE: Cervical open-door laminoplasty can enlarge the volume of the cervical vertebral canal and thus has become an effective and safe treatment for multilevel cervical disc herniation and cervical stenosis. Some post-surgery complications exist, such as reduction of cervical alignment and local kyphosis. However, aggravation of cervical disc herniation at the surgical level during short-term follow-up has not been discussed. Additionally, spontaneous disappearance of herniated disc pulposus is a common phenomenon in the lumbar region but is relatively rare in the cervical region...

INTRODUCTION: The patient was referred to an outpatient physical therapy clinic for lumbar radiculopathy by a primary care physician and subsequently referred for imaging due to suspicion of cervical myelopathy. The case highlights the clinical reasoning of the physical therapist differentiating between lumbar stenosis, cervical myelopathy, and upper cervical instability. To the author's knowledge, this is the only case report in the literature to describe the mechanism that could underpin a false positive Sharp-Purser test (SPT)...

The ongoing chronic inflammation and subsequent fibrosis play an important role in ligamentum flavum(LF) fibrosis and hypertrophy in patients with lumbar spinal canal stenosis (LSCS). Leptin is a chronic inflammatory mediator and involved in the fibrotic process in multiple organ systems. The present study aimed to investigate the role of leptin in LFfibrosis and its related regulatory mechanisms. The LF specimens were obtained during the surgery from 12 patients with LSCS(LSCS group) and 12 control patients with lumbar disc herniation (LDH group)...

To classify facet joint cysts (FJC) which will assist in identification of patient groups to best fit with a particular intervention. Sagittal T2 -weighted magnetic resonance images (MRI) of these patients are used to measure cyst size, while axial T2 -weighted MRI are used to determine the percentage of the vertebral canal occupied by the cyst. The degree of spondylolisthesis is also measured through standing X-rays or sagittal MRI. The proposed grading system is as follows. Grade I includes cysts that occupy less than 25% of the canal diameter that usually present with unilateral radiculopathy...

PURPOSE: A low cost, reproducible radiographic method of diagnosing congenital lumbar spinal stenosis (CLSS) is lacking. We hypothesized that the Cobb angle for lumbar lordosis would be smaller in patients with CLSS, based on observations in our spine clinic patient population. Here, we compared lumbar lordosis Cobb angles with the radiographic ratio method in patients with normal spine imaging, degenerative spinal stenosis, and with CLSS. MATERIALS AND METHODS: Orthopedic surgeons categorized patients with low back pain as "Normal," "Degenerative spinal stenosis," and "CLSS" based on clinical presentation and findings on lumbar magnetic resonance imaging...

Along with the population aging in China, patients with lumbar spinal stenosis(LSS) caused by recessive change incessantly increase. At present, there is no adequate evidence to recommend any specific nonoperative treatment for LSS, and surgery is still an effective method. The cilincal symptoms of the patients without conservative treatment got improvement after surgery, which is the strongest evidence base. Spinal instability after simple decompression promotes the development of fusion technique, and the accelerated adjacent segment degeneration and no relief in symptoms after fusion lead to dynamic fixation technology emerge as the times require...

Patients with low back pain (LBP) frequently undergo various imaging studies in the pursuit of a more precise diagnosis. Ultrasound (US) has the advantage of being a widely available, multiplanar, fast and radiation-free diagnostic tool. Moreover, compared to most of the other imaging modalities, it is particularly efficient in the visualization and assessment of soft tissues. Consequently, the question about the possible diagnostic application of US in such a common pathology as LBP is very relevant to the clinical practice...
