The term "greater trochanter" refers to a large bony prominence located on the lateral side of the femur bone in the human body. It is pronounced as /ɡreɪtər ˈtroʊkəntər/ in IPA phonetic transcription. The word "greater" is pronounced with a long "a" sound and emphasis on the first syllable, while "trochanter" is pronounced with a silent "ch" and emphasis on the second syllable. Correct spelling of this term is important in medical literature and discussions, particularly in the fields of orthopedics and anatomy.
The greater trochanter refers to a prominent bony projection situated on the upper end of the femur, the large bone of the thigh in vertebrates. It is one of the two main structures that make up the proximal or upper part of the femur, the other being the lesser trochanter. The greater trochanter is also known as the major trochanter or just trochanter major.
Anatomically, the greater trochanter is a bony lump that juts out on the outer side of the femur, just below the neck of the femur. It serves as a key attachment point for several muscles, tendons, and ligaments that play important roles in the function and movement of the hip joint. Some of the primary muscles that attach to the greater trochanter include the gluteus medius, gluteus minimus, piriformis, and obturator internus.
The greater trochanter can be palpated on the side of the hip and is used as a crucial landmark in various medical and orthopedic assessments. Understanding its location and anatomy is essential in diagnosing and treating conditions affecting the hip joint, such as trochanteric bursitis, hip fractures, and other injuries or diseases that impact this area. Overall, the greater trochanter plays a vital role in maintaining mobility, stability, and strength around the hip joint.

The word "trochanter" comes from the Greek word "trochantēr", which means "runner" or "ball" (referring to a spinning top). It is derived from the verb "trochō", meaning "to run". The word "greater" is an adjective used to indicate that there are other, smaller trochanters in the human body. So, the term "greater trochanter" refers to the larger of the two trochanters found on the femur (thigh bone).
