Which term refers to the groove located above the acetabulum?

• A. Supraacetabular groove
• B. Intertrochanteric line
• C. Infraspinous fossa
• D. Supra-styloid crest

Answer: (A)

The name for a groove just above the hip socket is the supraacetabular groove. Here, supra- means above and acetabular refers to the acetabulum, the socket of the hip joint, so the term points to a groove located superior to that socket on the pelvis. This location makes sense because the groove sits on the ilium near the rim of the acetabulum. Other terms describe different bones or regions—an intertrochanteric line is on the femur, the infracpinous fossa is on the scapula, and a supra-styloid crest isn’t a standard pelvis feature—so they don’t name the groove above the acetabulum.
