Abstract
Piriformis syndrome is believed to result from compression of the sciatic nerve around the piriformis muscle. Symptoms may include pain and numbness in the buttocks and down the leg. Intervention done by injecting steroid and local anaesthetic agents at the piriformis point is considered as a part of the important nonsurgical management of piriformis syndrome. The aim of this study was to observe the clinical improvement after piriformis point intervention using steroid and local anaesthetics in patients with chronic piriformis syndrome with radiation to lower limb. Twenty eight patients, a part from getting treatment with Non Steroidal Anti Inflammatory Drugs (NSAIDs), muscle relaxants, pregabalin, static spinal exercise, piriformis stretching exercise and local heat, received intervention at piriformis point with steroid and local anaesthetic. Patients were assessed by piriformis point tenderness, radiation, Straight Leg Raising test (SLR) and activity scores before and two weeks after intervention. Resultant data of twenty four patients who have completed the study were analysed in Statistica version6 software with appropriate statistical tools like Kolmogorov-Smirnov goodness-of-fit test, paired t test, frequency distribution. Significant improvement is noted in all outcome measurement tool scores. Though piriformis on both sides have shown improvement, significantly better improvement of piriformis tenderness of intervention side over opposite side clearly indicates towards the direct effect of intervention locally while not ruling out its indirect systemic effect on the opposite side as well.
Keywords: Piriformis Syndrome; Steroid and Local Anaesthetics, Piriformis point Intervention.
