Carpal and metacarpal bones fractures together with wrist ligaments lesions play a dominant role in these sports athletes. Fractures – especially metacarpal - are more frequent in professional athletes since they have already acquired a valid base technique and play with greater power and explosiveness. Ligament injuries are more common in amateur athletes since they have not full control over base techniques and not full mastery in striking the blow. Hook and uppercut are among the most common blows affecting wrist ligaments, whereas thumb ligament injury is more frequent in MMA, BJJ and Judo disciplines. Specific conditions may take place due to extended practicing. Painful subluxations of carpal and metacarpal bones, metacarpophalangeal joint capsule injury, cartilage gradual degeneration are among them.
