- Intracapsular femoral neck fractures account for 50% of all hip fractures and occur most commonly in elderly women and men. - The anatomy of the hip joint and biomechanics of the femoral neck make it susceptible to fractures, including the neck shaft angle and length of the hip axis. Poor bone quality from osteoporosis also increases risk. - The blood supply to the femoral head is an important factor in fracture healing, as fractures within the capsule rely solely on endosteal healing without cambial layer participation.
