A general hip fracture is a fracture of the proximal femur, the upper part of the thigh, near the hip joint area. Hip fractures, including femoral neck fractures, intertrochanteric fractures, and subtrochanteric fractures, are defined as fractures between the junction area of the femoral head and neck, to the base of the femoral neck, and intertrochanteric fractures are fractures occurring at the base of the femoral neck to above the level of the lesser trochanter. There are various definitions of a subrotor fracture, some consider it to be a fracture within 4 cm of the lesser trochanter to its underside, others consider it to be within 5 cm, and most scholars now define this fracture as one that occurs between the lesser trochanter and the isthmus of the femoral stem. Hip fractures account for about 7% of total body fractures in adults and 23.79% of total body fractures in older adults over 65 years of age, with more than 90% of these patients being older than 70 years of age and often being comminuted and significantly misaligned. Hip fractures in younger people are less common, mostly due to high-energy trauma, and are often combined with other fractures and trauma, and have a higher incidence of combined injuries requiring surgical treatment and a certain mortality rate. Overall, hip fracture is a low-energy fracture that occurs in the elderly, and minor trauma can lead to hip fracture in elderly patients with osteoporosis. Hip fracture has become a common and frequent disease in the elderly, and is characterized by high morbidity, hospitalization, disability and mortality.
