Popis: Introduction: Carpal Tunnel Syndrome (CTS) is one of the most common entrapment neuropathy with significant affection of hand function. Diagnosis is based on clinical, electrophysiological findings and ultrasonographic findings. Treatment may be nonsurgical or surgical. Of the nonsurgical methods, local glucocorticoid injection has yielded promising results in mild to moderate CTS. Use of different doses of steroid for CTS ranging from 12 mg to 40 mg with comparable results has been reported in the literature. To the best of our knowledge, efficacy of low dose steroid injection has not been evaluated in a comprehensive manner. Aim: To assess the efficacy of a low dose local steroid injection in CTS patients utilising clinical, electrophysiological and ultrasonographic parameters. Materials and Methods: Fifty five diagnosed patients of mild and moderate CTS, on the basis of electrophysiologic findings, were recruited for the study. Clinical evaluation was done in terms of grip strength and pain status. For baseline electrophysiological evaluation, nerve conduction studies were performed. This included Sensory Nerve Action Potentials (SNAPs), Sensory Distal Latency (SDL), Motor Distal Latency (MDL) and sensory and motor Conduction Velocity (CV) of median nerve as assessment parameters. Cross Sectional Area (CSA) of median nerve and bowing of flexor retinaculum was assessed using ultrasonography. Single dose of 20 mg methylprednisolone acetate was injected into the carpal tunnel under all aseptic precautions. Pain status was assessed at one week after the procedure. Overall, efficacy of the intervention was assessed using all the assessment parameters at one and three months after intervention. Statistical analysis was done using SPSS version 17 and p-value of
