Anatomical terminology[edit on Wikidata]

A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites. Humans have two, sometimes three, trochanters.

Etymology

"Trokhos" (Greek) = "wheel", with reference to the spherical femoral head which was first named "trokhanter". Later usage came to include the femoral neck.

Structure

• Greater trochanter
• Lesser trochanter
• Third trochanter, which is occasionally present

Other animals

• Fourth trochanter, of archosaur leg bones
• Trochanter (arthropod leg), a segment of the arthropod leg
