Sever?s disease is an inflammation of the growth plate in the heel, which is an area at the end of the developing bone where cartilage gradually turns into bone as kids grow. In fact, kids grow so rapidly at this age that their muscles and tendons can?t quite keep up with their feet and legs. This leaves the muscles and tendons tight and overstretched, particularly the Achilles tendon that connects the heel to the calf muscles. In fast-growing preteen and teen athletes, it can put so much pressure on the heel?s growth plate that it swells and becomes tender.
Mechanically, the heel takes a beating. And the apophyseal bone is located near the point of impact for the heel bone at heel strike and with most weight bearing activities. This includes running, jumping and walking. Heavy impact activities like soccer, football and gymnastics are commonly associated with this problem. In addition to this, there is traction on this apophyseal bone and the associated physeal line of growth cartilage. This traction on the apopysis (island of bone) along with the impact of weight bearing activities can lead to inflammation and pain. Tight Achilles and calf muscles also can contribute to this problem, and why stretching is discussed later.
Acute pain, pain asscoiatied with Sever?s disease is usually felt in the heel when the child engages in physical activity such as walking, jumping and or running. Highly active – children who are very active are among the most susceptible in experiencing Sever?s disease, because of the stress and tension placed on their feet.
This can include physical examination and x-ray evaluation. X-rays may show some increased density or sclerosis of the apophysis (island of bone on the back of the heel). This problem may be on one side or bilateral.
Non Surgical Treatment
Stretching programs. Strengthening exercises. Exercise and training modification. Orthotic therapy. In rare cases, where fragmentation of the apophysis exists and pain fails to subside with traditional treatments then immobilization of the foot and ankle with a short leg pneumatic walker(walking cast) is indicated.
