Introduction: Olecranon fractures are one of the most commonly seen orthopaedic injuries in the emergency room. The K-wire which is used in the AO Tension Band Wiring (TBW) technique resists the shear better than the figure of eight wire alone, but, it does not add compression to the fixation strength. But, the cancellous screw provides the strength of fixation i.e., by converting the tensile force to a compressive force at the fracture site, with additional resistance to the displacement due to the lag screw compression Our study is retrospective as well as prospective done between 1 September 2018 to 30 September 2019 for 13 months at B J Medical College, civil Hospital Ahmedabad with 34 cases. Objective To clinically evaluate the result of the 6.5 mm cancellous screw with washer V/s tension band wiring for fractures of the olecranon To assess Functional outcome and union rate among two methods In Mayo Type IB and IIA Fractures Material and Methods: sixteen cases of fractures of the olecranon which were treated by using 6.5mm AO cancellous screws with 32 mm threads, screw length of 80-105mm and 6.5 mm washer and 18 cases are treated with a 16 gauge TBW, were evaluated. All the cases were followed up and the results were analyzed by using a Mayo Elbow Performance Index. Results: Excellent results were achieved with 6.5mm CCS with Washer in 13(38.23%) patients while with TBW K wire 12(35.29%) patients, good results were achieved with 6.5mm CCS with Washer in 2(5.88%) patients while with TBW K wire 4(11.76%) patients fair results were achieved 6.5mm CCS with Washer in 1(2.94%) patients while with TBW K wire 2(5.88%) patients There were no poor results Conclusion:The technique of close reduction and internal fixation with 6.5 mm CCS is as effective method than open reduction and internal fixation with TBW.

Introduction: Chronic lumbo-sacral pain is a common and challenging clinical entity in pain management centre. The most commonly involved surgical indication are intractable leg or back pain and significant functional impairment that have been unresponsive to conservative measures. This is a level 2 evidence study where we have studied results of endoscopic discectomy and compared it to conventional discectomy procedure. Material and Methods: We selected 40 patients with severe low back pain radiating to one or both lower limbs, which has failed to resolve after prolonged conservative treatment and have less than level 3 disc prolapse. Oswestry Disability Index (For Low Back Pain) was recorded with questionnaire response and used as clinical tool for assessment. Results: Mean age of 40 patients was found to be 42.9 year with 80% patients having paracentral disc protrusion. Average operative time for endoscopic discectomy was 103 minutes which was higher than conventional discectomy (78 minutes). However, there was minimal blood loss compared to conventional discectomy. Based on ODI score, both endoscopic and conventional discectomy offered similar results in all grades. Conclusion: Endoscopic discectomy is a novel, safe and effective method that minimizes invasiveness of the surgical approach. Results achieved with this method are comparable to those achieved with open discectomy in terms of relief of symptoms on longer follow up, and is significantly better in terms of early mobilisation and morbidity as there is minimal tissue trauma.

The need to grasp large database structures is a very important issue in biological and life science. This review paper is aimed toward quantitative medical researchers searching for guidance in modeling large numbers of variables in medical research, how this relates to straightforward linear models and therefore the geometry that underlies their analysis. Issues reviewed include LASSO-related approaches, principal-component based analysis, and problems with model stability and interpretation. Model misspecification issues associated with potential nonlinearities are examined, as is that the Bayesian perspective on these issues.
