Most fractures of the fifth metacarpal are caused by trauma, and it usually takes 4 to 6 weeks for the fracture to reach clinical healing and about 3 months for full recovery. Fifth metacarpal fractures are usually treated by external fixation with plaster or internal fixation with surgery. If the fracture is well aligned, external fixation with plaster can be adopted, and the fixation time needs about 4 to 6 weeks, and the x-ray film will be reviewed at one month, if there is a continuous bone scab passing through the fracture end, it means that the fracture has reached the standard of clinical healing, and the plaster can be removed and rehabilitation training can be carried out. If the displacement of the fracture is obvious, surgical internal fixation is needed. The speed of clinical healing is slower than that of internal fixation, which takes about 6 to 8 weeks, but the fixation is stable, and rehabilitation training can be carried out at an early stage. When the fracture reaches clinical healing, it can only be engaged in some daily activities as well as rehabilitation training, and it takes about 3 months to return to normal bone hardness. The recovery time of fifth metacarpal fracture is also related to whether the patient suffers from other chronic diseases, age and other factors.
