After the metacarpal fracture, we should pay attention to the following aspects: first, we should pay attention to the local braking and rest of the fracture, and in some cases with the auxiliary external fixation, to do a good job of protection to prevent re-injury of the fracture site among the accidental injuries. Secondly, avoid cold and spicy food in the diet, avoid smoking and alcohol, balanced and adequate nutrition, including meat, eggs, milk, vegetables, fruits, dried fruits, fish and shrimp, without additional tonic intake. Finally, you can take oral medications to promote fracture healing, such as bone recovery pills and bone jointing pills, and also exercise the corresponding joints, such as the elbow joint and interphalangeal joint after metacarpal fracture surgery, which are helpful for future rehabilitation training. It is also important to take care of the regular review.
