A systematic review of the available literature comparing the outcomes of radiofrequency denervation to sham procedure in treating chronic low back pain caused by lumber zygapophysial joint pathology. Medline and EMBASE databases were searched for English language articles from 2005 to July 2010. Articles were considered for review if they satisfied the inclusion criteria: Randomised Controlled Trials(RCT) comparing radiofrequency neurotomy(RFN) to a ‘placebo’ procedure in patients with chronic low back pain caused by facet joint osteoarthritis. Adult patients of both sexes above 17 years of age who complained of continuous low back pain for more than 6 months with focal tenderness over the facet joints. Outcome measures of interest are pain improvement, physical activity, analgesic use, quality of life variables, range of motion of the lumbar spine and hip movement. Critical appraisal of the selected studies was carried out using the CASP appraisal tool for RCT.Aims

To assess the early subsidence rate of the femoral stem for patients who had collarless Corail total hip replacement. Consecutive data was collected retrospectively between August 2007 and December 2009 for patients who had collarless Corail total hip replacement. Radiographic assessment of the degree of subsidence, calcar resorption, stem angulation, canal fill ratio and loosening of the stem were measured. Post operative pain, dislocation and stem revision surgery were also evaluated.Aims
