When an elderly person has another fracture half a month after bone cementing and it hurts, they can take pain medication for emergency pain relief and have a secondary surgery on the fracture site to fix the bone. 1. Pain medication: If there is a second fracture after bone cement surgery, it will cause severe pain. For elderly patients, they can choose aspirin, ibuprofen or rofecoxib for local pain relief, but the pain relief effect is relatively weak. If the pain is more severe and needs to be relieved urgently, you can also choose opioids such as morphine under the guidance of the doctor to relieve pain quickly, but you need to control the dosage. 2. Surgical fixation: For the elderly patients with secondary fracture, they should go to the hospital for surgical fixation at the early stage of secondary fracture, and the secondary internal fixation through surgery can quickly stabilize the bone structure, help the fracture end to heal, and promote the health of bones. At the same time, it is necessary to protect the fracture site during the recovery period after the fracture surgery. Elderly people should go to the hospital immediately after the second fracture, and choose the appropriate painkillers under the guidance of the doctor, and use them carefully.
