Which type of hip fracture occurs at the base of the femoral neck, proximal to the trochanters?

The correct answer is based on the anatomical features of hip fractures. The type of hip fracture that occurs at the base of the femoral neck, proximal to the trochanters, is referred to as a transcervical fracture.

Transcervical fractures occur at the neck of the femur, just below the head and before the greater and lesser trochanters. This location plays a significant role in the vascular supply to the femoral head, as fractures in this area can lead to complications such as avascular necrosis due to interrupted blood supply.

Understanding the specific locations of different hip fractures is essential for proper diagnosis and treatment. While subcapital fractures occur just below the femoral head and are closely associated with the head itself, and peritrochanteric fractures involve significant trauma around the trochanters, transcervical fractures are specifically characterized by their location on the femoral neck, making their identification crucial in clinical settings.
