ABSTRACT
Objective: To investigate role of MRI in piriformis syndrome as a possible cause of lumbago and sciatica in Pakistani population.
Study Design: Cross sectional study
Place and Duration of Study: This study was conducted at Department of Neurosurgery, Lahore General Hospital Lahore, DHQ Hospital Sahiwal and Department of Neurosurgery Unit-1, Bolan Medical College Quetta from 1st July 2013 to 31st December 2015.
Materials and Methods: This study was conducted on 2000 cases who presented with moderate to severe low backach. Out of them eighteen patients of piriformis syndrome were selected after relevant general physical examination, neurological examination and investigations. Amongst them, thirteen were women, and five men, average age thirty six years. Planned surgery was performed in three cases, during follow up of one to two years following start of clinical presentation of patients. Rest of fifteen patients received corticosteroids injections in their piriformis. Magnetic Resonance Imaging was done in all individuals patients.
Results: Three cases executed successful outcomes with medical management. Out of three patients in which surgery was performed, two patients gave favourable clinical presentation, only single patient continued complaining of discomfort. 3 additional findings were demonstrated presenting as unusual pressure on sciatic nerve due to piriformis muscles. We obtained these results after keeping patients under observations for one to two years. The highest incidence of Piriformis syndrome was seen predominantly in females.
Conclusion: The important possible reason of lumbago and sciatica is positional variations of sciatic nerve with piriformis muscle. Low backach should be investigated in association with other environmental factors to look into causes of piriformis syndrome.
