Martial arts and kick boxing
A variety of injuries can occur as a result of martial arts and kick boxing. These include plantar fasciitis, Achilles tendonitis, sesamoiditis, and ankle sprains. Stretching is recommended for a minimum of 15 minutes before performing any kicking or punching.
Proper shoes are crucial to successful, injury-free aerobics. Shoes should provide sufficient cushioning and shock absorption to compensate for pressure on the foot many times greater than found in walking. They must also have good medial-lateral stability. Impact forces from aerobics can reach up to six times the force of gravity, which is transmitted to each of the 26 bones in the foot.
Activities such as football, basketball, soccer, field hockey and lacrosse often lead to ankle and big toe joint injuries as a result of play on artificial surfaces.
Big toe injuries also called "turf toe," often result from hyperextension of the big toe joint as the heel is raised off the ground. An external force is placed on the great toe and the soft tissue structures that support the big toe on the top are torn or ruptured.
Symptoms include pain, tenderness and swelling of the toe joint. Often there is a sudden acute onset of pain during push-off phase of running. Usually, the pain is not enough to keep the athlete from physical activities or finishing a game. This causes further injury to the big toe and will dramatically increase the healing time.
Osteochondromas are benign bone tumors under the toenail. They form in the bone beneath the toenail. An osteochrondroma accounts for about half of all benign bone tumors, occurring mostly in children and young adults. Unless they cause irritation to the surrounding tissue, they are generally not very painful.
Sometimes, they can deform the toenail and cause an ingrown toenail. In some cases, they are removed surgically.
Osteochondritis (stiff ankle)
These are lesions that usually cause pain and stiffness of the ankle joint and affects all age groups. Often, osteochondritis usually follow a twisting type injury to the ankle.
