OBJECT The aim of this study was to describe the pelvic parameters in a sample of healthy Mexican volunteers and to compare them with previously reported data for Caucasian and Asian populations. METHODS This was a transversal study that included a sample population of healthy Mexican volunteers. Age, sex, and lateral radiographs of the lumbosacral region(More)
OBJECT This prospective cohort study was designed to determine the influence of depressive symptoms on patient expectations and the clinical outcomes of the surgical management of lumbar spinal stenosis. METHODS Patients with an age > 45 years, a diagnosis of lumbar spinal stenosis at one level, and an indication for decompressive surgery were included in(More)
Decompression surgery for lumbar spinal stenosis is a common procedure. After surgery, segmental instability sometimes occurs, therefore, different methods for restabilization have been developed. Dynamic stabilization systems have been designed to improve segmental stability. In this study, clinical results of patients with lumbar spinal stenosis that(More)
BACKGROUND A feasibility trial was conducted to evaluate the initial safety and clinical use of a next-generation artificial cervical disc (M6-C artificial cervical disc; Spinal Kinetics, Sunnyvale, CA) for the treatment of patients with symptomatic degenerative cervical radiculopathy. A standardized battery of validated outcome measures was utilized to(More)
The use of cannulated screws for internal fixation of slipped capital femoral epiphysis (SCFE) is recognized as the standard method of treatment and has fewer complications compared with previous methods such as pins or tri-flanged nails. Some complications related to guidewires have been reported in the treatment SCFE. The most dangerous complication is(More)
Study Design Case report. Objective The diagnosis and surgical management of a patient with traumatic bilateral posterior dislocation of L4-L5 is presented with a thorough review of the existing literature. Summary of Background Data Traumatic dislocation of L4-L5 has been reported in the English literature in only five cases; of these, only two were(More)
INTRODUCTION We need to evaluate the efficacy and safety of the use of dynamic fixation in patients with narrow lumbar through comparing the assessment of two years with 4 years of follow-up. METHODS Prospective, longitudinal, autocontrol deliberately and sequential intervention, in lumbar stenosis patients who made treatment with dynamic stabilization(More)
BACKGROUND Vertebral hemangioma is the most common benign spinal tumor and is found in 11% of postmortem studies as a slow-growing benign vascular malformation. It usually involves the vertebral body and sometimes the posterior vertebral elements. When the posterior elements are involved, spinal cord compression with neurological symptoms are seen more(More)
BACKGROUND Ligamentoplasty is a dynamic stabilization method used to treat lumbar stenosis and resect lumbar herniated discs with good results. The objective of this paper is to report preliminary results of the utility of ligamentoplasty to prevent adjacent segment disease above the arthrodesis. MATERIAL AND METHODS Two groups of patients with(More)
INTRODUCTION Obesity is an increasing problem of epidemic proportion, and it is associated with various musculoskeletal disorders, including impairment of the spine. However, the relationship between obesity and spino-pelvic parameters remains to date unsupported by an objective measurement of the mechanical behavior of the spino-pelvic parameters depending(More)
