Incidental finding of an accessory slip of the piriformis muscle in the gluteal region is reported. Following routine dissection of the gluteal region in three formalin-fixed cadavers, an accessory slip of the piriformis was observed. The accessory slip was cleaned, attachments were identified, and dimensions were measured in two parts as fleshy and tendinous parts with a graduated scale to the...

INTRODUCTION Gluteal compartment syndrome is a rare, often unrecognized syndrome that may manifest as renal failure, sepsis, and death. Delay in diagnosis can result in significant morbidity and possible mortality. We report a case of occult gluteal compartment syndrome causing unresolving rhabdomyolysis. CASE PRESENTATION A 50-year-old Caucasian American man with history of chronic obstructi...

Nicolau syndrome is a rare complication of intramuscular injection that leads to local ischemic necrosis of the skin and adipose tissue. In this paper, we discuss etiologies, risk factors, and treatment options for gluteal Nicolau syndrome referring to patients treated in our hospital. Our study includes 17 women who visited our clinic with symptoms of gluteal necrosis secondary to intramuscula...

We investigated the relationship of the inferior gluteal nerve to gluteus maximus by dissecting the muscle in 12 fresh-frozen and formalin-treated cadavers. The anatomy was recorded using still digital photography. The course of the inferior gluteal nerve was carefully traced and was noted to enter the deep surface of gluteus maximus approximately 5 cm from the tip of the greater trochanter of ...

Gluteal muscle contracture (GMC), a debilitating disease, exists all over the globe but it is much more prevalent in China. Patients typically present with abduction and external rotation of the hip and are unable to bring both the knees together while squatting. Multiple etiologies have been postulated, the commonest being repeated intramuscular injection into the buttocks. The disease is diag...

STUDY DESIGN Experimental laboratory study. OBJECTIVES To quantify and compare electromyographic signal amplitude of the gluteus maximus and gluteus medius muscles during exercises of varying difficulty to determine which exercise most effectively recruits these muscles. BACKGROUND Gluteal muscle weakness has been proposed to be associated with lower extremity injury. Exercises to strengthe...

Leiomyosarcomas are rare tumours of smooth muscle origin, and there have been no reported cases of such tumours arising within the ischiorectal fossa. Surgical resection with clear margins remains the gold standard treatment; however, there is limited literature on surgical approaches to the ischiorectal fossa for such tumours. We report a case of a high-grade leiomyosarcoma in a 59-year-old la...
