BMC Musculoskeletal Disorders - Latest articlesThe latest articles from BMC Musculoskeletal Disorders (ISSN 1471-2474) published by BioMed CentralTime-Action Analysis (TAA) of the Surgical Technique Implanting the Collum Femoris Preserving (CFP) Hip Arthroplasty TAASTIC trial Identifying pitf- June 24, 2008 Background: Two types of methods are used to assess learning curves: outcome assessment and process assessment. Outcome measures are usually dichotomous rare events like complication rates and survival or require an extensive follow-up and are therefore often inadequate to monitor individual learning curves. Time-action analysis (TAA) is a tool to objectively determine the level of efficiency of individual steps of a surgical procedure. Methods Design: We are currently using TAA to determine..http://www.biomedcentral.com/1471-2474/9/93 Complex regional pain syndrome 1 - the Swiss cohort study- June 23, 2008 Background: Little is known about the course of Complex Regional Pain Syndrome 1 and potential factors influencing the course of this disorder over time. The goal of this study is a) to set up a database with patients suffering from suspected CRPS 1 in an initial stadium, b) to perform investigations on epidemiology, diagnosis, prognosis, and socioeconomics within the database and c) to develop a prognostic risk assessment tool for patients with CRPS 1 taking into account symptomatology and...http://www.biomedcentral.com/1471-2474/9/92 Study to Prospectively evaluate Reamed Intramedually Nails in patients with Tibial fractures (S.P.R.I.N.T.): Study Rationale and Design- June 23, 2008 Background: Surgeons agree on the benefits of operative treatment of tibial fractures - the most common of long bone fractures - with an intramedullary rod, or nail. Rates of re-operation remain high - between 23% and 60% in prior trials - and the two alternative nailing approaches, reamed or non-reamed, each have a compelling biological rationale and strong proponents, resulting in ongoing controversy regarding which is better. Methods: The objective of this trial was to assess the...http://www.biomedcentral.com/1471-2474/9/91 Altered motor control patterns in whiplash and chronic neck pain.- June 20, 2008 Background: Persistent whiplash associated disorders (WAD) have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM), conjunct motion, joint position error...http://www.biomedcentral.com/1471-2474/9/90 Gait analysis does not correlate with clinical and MR imaging parameters in patients with symptomatic lumbar spinal stenosis- June 20, 2008 Background: Parameters of MR imaging play a pivotal role in diagnosing lumbar spinal stenosis (LSS), and serve as an important tool in clinical decision-making. Despite the importance of MR imaging, little is known about the correlation between MRI parameters, objective gait analysis, and clinical presentation of patients with lumbar spinal stenosis. Methods: Sixty-three patients from our clinic with symptomatic lumbar spinal stenosis leading to neurogenic claudication were included in this...http://www.biomedcentral.com/1471-2474/9/89 Biomechanical comparison of a new stand-alone anterior lumbar interbody fusion cage with established fixation techniques- a three-dimensional finite e- June 18, 2008 Background: Initial promise of a stand-alone interbody fusion cage to treat chronic backache and restore disc height has not been realized. Others have used a posterior spinal fixation in conjunction to enhance stability and promote fusion rate. Presently, a new stand-alone cage is compared with conventional fixation methods based on the finite element analysis, investigating cage-bone interface mechanics and stress distribution on the adjacent tissues. Methods: Three trapezoid 8-degree...http://www.biomedcentral.com/1471-2474/9/88 A simplified guide ruler from numeric table method in doing rotational osteotomy- June 16, 2008 Background: Cobeljic et al. recently reported a numeric table method to provide precise rotational osteotomy which is a well established orthopaedic procedure. The numeric table requires four pages in length that is rather inconvenient during performing an osteotomy operation. Methods: We thus develop our own method by summarizing the data of the four-page table into a small ruler, which is easy to carry and use in operation room. An electrical version of this ruler is also available. We also..http://www.biomedcentral.com/1471-2474/9/87 Isolation and characterization of side population stem cells in articular synovial tissue- June 12, 2008 Background: Autologous chondrocyte implantation is an established technique for the repair of degenerated articular cartilage. Recently, the detection of side population (SP) cells, which have the ability to strongly efflux Hoechst 33342 (Ho) fluorescence dye, has attracted attention as a method of stem cell isolation. Although SP cells from synovial tissue were expected to be an excellent source for this tissue engineering, their precise character in the synovial tissue has not been...http://www.biomedcentral.com/1471-2474/9/86 Gender difference in symptomatic radiographic knee osteoarthritis in the Knee Clinical Assessment - CAS(K): a prospective study in the general populat- June 11, 2008 Background: A recent study of adults aged 50+ years reporting knee pain found an excess of radiographic knee osteoarthritis (knee ROA) in symptomatic males compared to females. This was independent of age, BMI and other clinical signs and symptoms. Since this finding contradicts many previous studies, our objective was to explore four possible explanations for this gender difference: X-ray views, selection, occupation and non-articular conditions. Methods: A community-based prospective study....http://www.biomedcentral.com/1471-2474/9/82 Choline-stabilized orthosilicic acid supplementation as an adjunct to CalciumVitamin D3 stimulates markers of bone formation in osteopenic females: a- June 11, 2008 Background: Mounting evidence supports a physiological role for silicon (Si) as orthosilicic acid (OSA, Si(OH)4) in bone formation. The effect of oral choline-stabilized orthosilicic acid (ch-OSA) on markers of bone turnover and bone mineral density (BMD) was investigated in a double-blind placebo-controlled trial. Methods: Over 12-months, 136 women out of 184 randomized (T-score spine < -1.5) completed the study and received, daily, 1000 mg Ca and 20 microg cholecalciferol (Vit D3) and...http://www.biomedcentral.com/1471-2474/9/85 |
