Severs disease or calcaneal apophysitis causes heel pain usually in growing children between age nine and fourteen. It occurs as a result of disturbance during the final development of the heel growth plate. During this time the achilles tendon is pulling strongly on the heel bone and this excessive force can cause inflammation and pain.
During the growth spurt of early puberty, the heel bone (also called the calcaneus) sometimes grows faster than the leg muscles and tendons. This can cause the muscles and tendons to become very tight and overstretched, making the heel less flexible and putting pressure on the growth plate. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (force or pressure) on the already tight Achilles tendon damages the growth plate, causing the swelling, tenderness, and pain of Sever's disease. Such stress commonly results from physical activities and sports that involve running and jumping, especially those that take place on hard surfaces, such as track, basketball, soccer, and gymnastics.
In Sever?s disease, heel pain can be in one or both heels. It usually starts after a child begins a new sports season or a new sport. Your child may walk with a limp. The pain may increase when he or she stands on tiptoe. Your child?s heel may hurt if you squeeze both sides toward the very back. This is called the squeeze test. Your provider may also find that your child?s heel tendons have become tight.
To diagnose the cause of the child?s heel pain and rule out other more serious conditions, the foot and ankle surgeon obtains a thorough medical history and asks questions about recent activities. The surgeon will also examine the child?s foot and leg. X-rays are often used to evaluate the condition. Other advanced imaging studies and laboratory tests may also be ordered.
Non Surgical Treatment
Your physiotherapist will guide you and utilise a range of pain relieving techniques including joint mobilisations for stiff ankle or subtalar joints, massage or electrotherapy to assist you during this pain-full phase. Your physiotherapist will identify stiff joints within your foot and ankle complex that they will need to loosen to help you avoid overstress. A sign that you may have a stiff ankle joint can be a limited range of ankle bend during a squat manoeuvre. Your physiotherapist will guide you. Your foot arch is dynamically controlled via important foot arch muscles, which be weak or have poor endurance. These foot muscles have a vital role as the main dynamically stable base for your foot and prevent excessive loading through your plantar fascia. Any deficiencies will be an important component of your rehabilitation. Your physiotherapist is an expert in the assessment and correction of your dynamic foot control. They will be able to help you to correct your normal foot biomechanics and provide you with foot stabilisation exercises if necessary.
