How long after breaking arm before playing contact sport?

Depends: This depends on many factors. This includes what part of your arm was broken as an example was it the shaft was it a part of your joint. How was it treated with cast immobilization or surgery. How far out are you from your injury and healing. In general i tell my patients that they may resume contact sports 4 to 6 weeks after removal of their cast or brace. Again this is a complicated question i would refer you back to your provider to answer this.
