Hip fractures in the elderly: A Clinical Anatomy Review

As elderly populations rise worldwide, the amount of hip fractures have continued to increase and result in substantial medical burdens in many countries. This increase goes hand-in-hand with an increase in surgical procedures to correct hip fractures. The medical burden imparted by hip fractures and their corrective surgeries necessitate a clinically relevant understanding of the hip joint including the vascular, neural, and musculoskeletal structures directly associated with and neighboring the joint. It is critical to appreciate how the normal hip anatomy is disrupted by a fracture and how this disruption is heavily influenced by the fracture's location. The effects of advancing age on the integrity of the hip joint and the risk of hip fractures further complicate hip anatomy. Consequentially, normal hip anatomy, aging and the pathology introduced by fractures play major roles in how hip fractures are approached surgically. This article aims to review the clinically relevant anatomy of the healthy hip joint, age-related changes that influence the joint, hip fractures, and corrective surgeries for hip fractures. Clin.
