If you have a thumb contusion from playing basketball, pay attention to the local swelling and whether there is any significant restriction of movement. If there is a significant restriction of movement, pain and swelling, the possibility of a fracture should be noted. If there is a fracture, the treatment plan will be determined according to the displacement of the fracture; if there is no obvious displacement, it can be treated conservatively with plaster fixation and braking; if there is obvious misalignment, it needs to be repositioned by manipulation; if manipulation cannot maintain good functional repositioning, surgical repositioning and fixation should be considered. If it is only a general soft tissue contusion, rest for a few days, do not exert force in the local area for a while, and then you can use local spray such as swelling and pain aerosol to help recovery.
