Weight-Bearing Restrictions

WEIGHT-BEARING RESTRICTIONS Some bone and joint injuries may not allow you to put your body weight on the bone or joint to let the injury heal. Based on your injury, you will be taught to follow limits on the amount of weight you can put on the injured arm or leg. These are often called weight-bearing .
