There are four different types of scaphoid fractures, but, in all cases, immobilising the fracture in a cast provides a 90 to 100 percent success rate. The average time it takes to heal is nine to 12 weeks, though this can be shortened by using screws.
The pain, which often is mild, is worsened by gripping or squeezing. When punching, a fracture can occur as a result of the concentration of external force on the second metacarpal of your fist. This force travels to the trapezium and trapezoid bones and produces a shearing stress on the scaphoid.
The correct boxing technique, wrist support and wrist strengthening exercises can reduce the risk of injury from sports. If you’ve started boxing, make sure your wrist is not bent when making contact with the punchbag.
