Severs Disease PhysiotherapyOverview
Sever disease, first described in 1912, is a painful inflammation of the calcaneal apophysis. It is classified with the child and adolescent nonarticular osteochondroses. (The other disease in this group is Iselin disease, which is inflammation of the base of the fifth metatarsal.) The etiology of pain in Sever disease is believed to be repetitive trauma to the weaker structure of the apophysis, induced by the pull of the tendo calcaneus (Achilles tendon) on its insertion. This results in a clinical picture of heel pain in a growing active child, which worsens with activity. Sever disease is a self-limited condition, accordingly, no known complication exists from failure to make the correct diagnosis.
Severs disease is often associated with a rapid growth spurt. As the bones get longer, the muscles and tendons become tighter as they cannot keep up with the bone growth. The point at which the achilles tendon attaches to the heel becomes inflamed and the bone starts to crumble (a lot like osgood schlatters disease of the knee). Tight calf muscles may contribute as the range of motion at the ankle is reduced resulting in more strain on the achilles tendon. Sever's disease is the second most common injury of this type which is known as an apophysitis.
Symptoms include heel pain related to sports activities and worsen after those sport and exercise activities. However, some children who are not in a sport may also get this if they are physically active. If you notice that your child is ?walking on their toes? this is a sign of possible heel pain. The pain is usually on the back of the heel, the sides of the heel, the bottom of the heel, or a combination of all of these. We typically don't see swelling with this, however if pressure is applied to the sides of the heel pain may be reported. Sometimes the pain is so bad the child will have to limp, or take a break from sports activity either for a few days or few months.
Sever?s disease can be diagnosed based on your history and symptoms. Clinically, your physiotherapist will perform a "squeeze test" and some other tests to confirm the diagnosis. Some children suffer Sever?s disease even though they do less exercise than other. This indicates that it is not just training volume that is at play. Foot and leg biomechanics are a predisposing factor. The main factors thought to predispose a child to Sever?s disease include a decrease in ankle dorsiflexion, abnormal hind foot motion eg overpronation or supination, tight calf muscles, excessive weight-bearing activities eg running.
Non Surgical Treatment
Depending on the Podiatrist's diagnosis and the severity of the pain, there are several treatment options available. Rest/ reduced activity: your child should reduce or stop any activity that causes pain, such as sports and running. This can be a difficult option, as children are normally quite willful in pursuit of their favorite pastimes! Over the counter anti-inflammatory drugs, such as ibuprofen (found in Nurofen), to help reduce pain and inflammation. Try to make sure your child does the recommended stretching exercises before sport/play. This will should help reduce the stress on the fascia tendon and relieve heel pain. The use of Orthotic insoles. Footactive Kids orthotics are made for children. They will help properly support the foot, help prevent over-pronation or improper gait restoring your child's foot the the correct biomechanical position. If you are in any doubt or your child's foot pain persists then please arrange an appointment with a Podiatrist or Physiotherapist.

One of the most important things to know about Sever's disease is that, with proper care, the condition usually goes away within 2 weeks to 2 months and does not cause any problems later in life. The sooner Sever's disease is addressed, the quicker recovery is. Most kids can return to physical activity without any trouble once the pain and other symptoms go away. Although Sever's disease generally heals quickly, it can recur if long-term measures are not taken to protect the heel during a child's growing years. One of the most important is to make sure that kids wear proper shoes. Good quality, well-fitting shoes with shock-absorbent (padded) soles help to reduce pressure on the heel. The doctor may also recommend shoes with open backs, such as sandals or clogs, that do not rub on the back of the heel. Shoes that are heavy or have high heels should be avoided. Other preventive measures include continued stretching exercises and icing of the affected heel after activity.
