If one of the screws is loose in the X-ray after femoral head surgery, it needs to be dealt with according to the healing situation. If the bone has basically healed, appropriate bed rest is sufficient. If the bone has not yet healed, then you need to consider secondary surgery or targeted treatment. 1. Bone healing: If the bone scab is continuous and not separated when X-ray is taken after femoral head surgery, it means that the fracture is clinically healed, and if the screw is found to be loosened at this time, it usually does not need special treatment. Loose screws will not affect the subsequent recovery too much, as long as the appropriate bed rest and control the amount of activity can be. 2. Bones are not healed: If the screws are loosened in the early stage of post-surgical recovery, it may lead to misalignment or growth of bones in the later healing process. If the internal fixation screws are loose, it is possible that the fracture may not heal or may be infected, which may require a second surgery. If the screw loosens after artificial joint replacement, infection, osteolysis, and loosening of the artificial joint are considered possibilities, and these cases need to go to the hospital for targeted treatment. After femoral head surgery, do not perform strenuous exercise in the short term to avoid loosening of the screws and take regular radiographs.
