Hip Fracture

#hip fracture, #fall, #femur, #hip bone fracture, #joint replacement, #fracture fixation, #osteoporosis, #fracture in older adults

A hip fracture is the most serious type of fracture that occurs after a fall. The hip joint is the joint where the pelvic bone and the thigh bone (femur) connect. After a fracture, a person cannot bear weight or stand, which makes walking independently difficult, and in older patients it can lead to complications such as pneumonia, pressure sores, and sepsis, so mortality is high. If you have pain in the hip or upper thigh after a fall, please consult an orthopedic specialist right away.
