RADIOLOGICAL EVALUATION OF PEDICLE SCREW FIXATION IN THORACOLUMBAR SPINE STABILIZATION BY FREE HAND TECHNIQUE

Abstract

Introduction: Pedicle screw xation is the preferred modality of xation throughout the vertebral column because of its proven effectiveness in stabilizing all three columns even in a deformed spine. With no use of imaging, the duration of the procedure is substantially reduced, this decrease reects progressively in post-operative prognosis as probability of surgical site infection is minimal. Further curtailed duration of prone position also helps in reducing the morbidity associated with the surgery.In this study we have attempted to evaluate the safety and accuracy of pedicle screw placement at thoracolumbar spine by free hand technique using post-operative computed tomography analysis. To evaluate the efcacy of free hand technique in sa Objectives; fe and accurate placement of pedicle screw post operatively using CT image. Study design : Prospective .Study population :Patients undergoing posterior stabilisation with pedicle screw xation by free hand technique. 100patients. March 2014 until September 2020. Department Sample size: Study period: Study setting: of Orthopaedics, Chengalpattu Govt Medical College and Hospital There is statis Results ; tically signicant association in ODI and VAS score among study participants during follow up(P<0.05). Free hand technique provides a safe and acc Conclusion: urate method of pedicle screw placement without radiation harm to surgeon, theatre staffs and the patients.Free hand technique by reducing the duration of surgery, indirectly decrease complications like surgical site infection, anaesthetic complications
