ABSTRACT
Introduction: Lumbar spondylolisthesis is frequently found in adults as a result of spondylolysis or facet degeneration. The slipped segment produces abnormal positioning of the vertebrae in relation to each other along the spinal column and causes mechanical back pain and compression of neural structures. The initial treatment in most symptomatic patients with lumbar spondylolisthesis is nonoperative supportive care, which consists of a combination of pain medications, bracing, and physical therapy. Surgical intervention is indicated if the symptoms are disabling and they interfere with work despite supportive care, if there is progression of the slippage degree (SD) on serial radiologic examinations, or if there are overt neurological deficits 1,2. Pedicle screw placement is the most popular method in lumbar spinal instrumentation for achieving successful fusion. Recently, to reduce surgical damage to the normal muscular structures during pedicle screw placement, C-arm-guided percutaneous pedicle screw fixation (PPSF) was introduced, and it has become increasingly popular in spinal surgery. Percutaneous transpedicular fixation systems have become more widely used in recent years mainly for the treatment of dorsal, dorsolumbar, and lumbar instability. Aim & Objectives: The present study is aimed at evaluating the functional outcome with percutaneous pedicle screw fixation for spinal fractures& spinal instabilities by free hand technique in patients without neurological deficits. Materials & Methods: The present dissertation is a study of 25 consecutive cases of spinal fractures and spondylolisthesis who attended the orthopaedic emergency or outpatient department of Andhra medical college, Visakhapatnam from 2017 to 2019. All the cases were examined clinically fallowed by radiographic confirmation. Results: In total 25 patients spinal fractures 16 and instability 9, whose mean preoperative ODI scores is 81.04% and the mean postoperative score is 22.6 %. The total postoperative moderate disability patients are15 and minimal disability patients are 10. “PERCUTANEOUS CD FIXATION OF SPINE IN SPINAL FRACTURES/INSTABILITY BY FREEConclusion: HAND TECHNIQUE” is one of the better methods and is suggested for grade 1 & grade 2 spondylolisthesis and spinal fractures, also by which can reduce the morbidity and improve the function.
