Why does hip fracture cause hip pain?

A fracture interrupts the normal strength of the upper thigh bone near the hip. Movement can make the broken area shift slightly, while the joint capsule, muscles and ligaments around it may also become inflamed. This is why pain may be felt in the outer hip, groin or upper thigh, and why turning, standing or taking a step can make it worse. Pain can also lead to guarding: the muscles tighten and you naturally avoid moving the leg. A fracture may occur after a fall or another force, but weakened bone can sometimes break during an ordinary movement. Hip pain has many possible causes, so an examination and imaging are needed to identify the source.

If a fracture is possible, stop walking on the painful leg and keep the hip as still as you can. Do not try to straighten the leg, test its strength repeatedly or travel alone. Arrange urgent medical assessment, especially after a fall or sudden impact. A clinician may examine leg position and movement and request imaging. Until help arrives, keep warm, avoid food or drink if an operation might be needed, and follow local emergency advice about safe transport. Do not use crutches unless a clinician has shown you how to use them safely.

Seek emergency care immediately for severe hip or groin pain after an injury, inability to stand or bear weight, a leg that looks shorter or turned outward, new numbness, a pale or cold foot, heavy bleeding or faintness. Do not wait for pain to settle overnight. If pain began without a clear injury but is worsening or is stopping normal walking, arrange prompt clinical review. These symptoms require assessment because delaying care can make movement and treatment more difficult.

Ask: Where is the fracture, and does it involve the joint? What imaging is needed? Should I avoid all weight on the leg? What pain relief is appropriate with my other medicines? What treatment or operation is being considered, and what will recovery involve? When can physiotherapy begin, and how will falls be prevented?
