The presence of an IGN injury was considered in patients with weakness in the gluteusmaximus (GM) muscle or in those who demonstrated needle electromyography (EMG)abnormality in the GM muscle.Results: There were 44 (95.6%) patients with an SN injury only, 1 (2.2%) patient with bothan SN and an IGN injury, and 1 (2.2%) patient with an IGN injury only. The complaints of thepatient with an IGN injury only occurred within hours to days after the IM injection; thispatient had no muscle weakness. The complaints of the patient with both IGN and SN injuriesoccurred minutes to hours after IM injection; this patient had mild weakness in the plantarflexion of the foot. In 40 of the patients with only an SN injury, complaints occurredimmediately after or within a few seconds following the IM injection, while complaintsoccurred within minutes to hours in the remaining 4 patients.Conclusion: Although rare when compared to SN injury, the IGN can be injured by IMinjection. Therefore, the GM muscle should be examined with needle EMG in patients withcomplaints associated with IM injection. Muscle weakness may not occur in nerve injuries dueto IM injections.en10.18678/dtfd.743008info:eu-repo/semantics/openAccessArticle223161165442606
