Comparing the Distances of Different Intramuscular Gluteal Injection Sites to the Sciatic Nerve

Introduction: Sciatic nerve injury is a well-known complication of intra-muscular gluteal muscle injections. Affected individuals usually present with foot drop and this results in varying degrees of motor disability. There are different sites such as ventrogluteal, dorsogluteal that can be used for gluteal injections. In last years, the ventrogluteal site is accepted as a more safe and suitable injection site than dorsogluteal site. This study was carried out to compare the distance to the siatic nerve under the piriformis muscle of these different gluteal injection sites. The study also aimed to evaluate the muscle thicknesses at these injection sites.
