It constitutes an important surgical landmark in the identification of structures that emerge above and below it.<\/p>\n<p style=\"text-align: justify;\"><strong>Materials and Methods:<\/strong> Twenty embalmed cadavers were studied during routine dissection for first year MBBS students in the department of Anatomy at Dr.B.R.Ambedkar Medical College, Bangalore.<\/p>\n<p style=\"text-align: justify;\"><strong>Observations and Results:<\/strong> Out of twenty cadavers, in two cadavers we observed piriformis muscle being pierced by the nerves.<\/p>\n<p style=\"text-align: justify;\"><strong>Conclusion:<\/strong> The variations in the exit routes of the structures in relation to piriformis muscle is important for surgeons, as this is the area of frequent surgical manipulation during hip replacement surgery, nerve injury during deep intramuscular injections in gluteal region.<\/p>\n<p style=\"text-align: justify;\"><strong>KEY WORDS:<\/strong> Piriformis Muscle, Hip Replacement Surgery, Intramuscular Injections, Gluteal Region.<\/p>\n<p style=\"text-align: justify;\"><strong>REFERENCES<\/strong><\/p>\n<ol>\n<li style=\"text-align: justify;\">Hollinshead W H.
