Severs Disease Rehab

Overview


Sever's disease is a mild traction injury of the heel. There is an apophysitis at the point of the insertion of the Achilles tendon. This condition is treated by raising the heel of the shoe a little, calf-stretching and avoiding strenuous activities for a few weeks.


Causes


Apart from the age of the young person, other factors that may contribute to developing the disease may include; overuse or too much physical activity. Your child?s heel pain may be caused by repeated stress on the heels (running and jumping activities), pressure on the back of the heel from too much standing or wearing poor-fitting shoes. This includes shoes that do not support or provide enough padding for your child?s feet.


Symptoms


Often the condition is self limiting; meaning as the growth plate fuses to the rest of the heel bone, the pain will subside. However in some cases the child will have so much discomfort that they will be unable to walk comfortably if left untreated. Therefore, heel pain in children should always by evaluated by a physician.


Diagnosis


Radiography. Most of the time radiographs are not helpful because the calcaneal apophysis is frequently fragmented and dense in normal children. But they can be used to exclude other traumas. Ultrasonography. could show the fragmentation of secondary nucleus of ossification of the calcaneus in severs?s disease. This is a safe diagnostic tool since there is no radiation. This diagnostic tool can also be used to exclude Achilles tendinitis and/or retrocalcaneal bursitis.


Non Surgical Treatment


Treatment for Sever?s disease is mainly supportive, to stop inflammation and reduce pain. The condition will resolve on its own when the growth in the growth plate is complete, but until then, measures can be taken to resolve pain and discomfort. Applying ice to the painful or swollen areas on the foot may provide some short-term relief from pain and prevent further inflammation. Ice can be applied for about 20 minutes two or three times a day. Footwear that is too big, too small, or does not provide proper support can exacerbate the symptoms of Sever?s disease. Supportive footwear is important to prevent discomfort, especially in children who participate in sports and activities that take place on a hard surface (such as pavement or a basketball court). Shoes should also have adequate padding and not rub against the heel. In some cases, shoes that do not have heels (such as sandals) may be more comfortable to wear while the heel is healing, but care should be taken that the shoe provides proper support to the rest of the foot. Children with Sever?s disease should avoid going barefoot.Children with flat feet, high arches, or over-pronation may need treatment to resolve these underlying conditions. In many cases, an orthotic worn inside the shoe can help put the foot into a better alignment and provide relief to the foot or the arch. Children who are overweight or obese may be counseled to lose weight. Being overweight can contribute to the development of several conditions, including Sever?s disease. Resting the foot and discontinuing sports and other activities until the pain and stiffness is resolved may be recommended. In extreme cases, a walking boot or a cast might be used to completely immobilize the foot. A physical therapist may recommend stretching exercises for the muscles in the calf and the Achilles tendon. A stretching routine is usually done several times a day. Stretching these muscles can help improve strength and decrease the stress on the heel plate. Some physicians may recommend over-the-counter pain relievers such as ibuprofen or acetaminophen. Care must be taken when administering these medications to children, especially with acetaminophen, as overdoses are possible when using more than one medication containing acetaminophen. Aspirin should never be given to children. The utility of pain relievers in children must be weighed against their possible side effects. For small variations-less than an inch or so-shoe lifts can help equalize the length of the legs. In cases with more variation between legs, surgical solutions may be considered. Research indicates that targeted manual therapy techniques performed by a licensed physical therapist can help to reduce pain from Sever?s Disease and to improve muscle function. When the larger calf muscles and the smaller ankle and foot muscles become tight, this tightness can affect the mechanics of the ankle joint. Manual therapy includes both joint and muscle release techniques to restore optimal function to the calf, ankle, and foot muscles, and results can generally be achieved within a few months.


Surgical Treatment


The surgeon may select one or more of the following options to treat calcaneal apophysitis. Reduce activity. The child needs to reduce or stop any activity that causes pain. Support the heel. Temporary shoe inserts or custom orthotic devices may provide support for the heel. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Physical therapy. Stretching or physical therapy modalities are sometimes used to promote healing of the inflamed issue. Immobilization. In some severe cases of pediatric heel pain, a cast may be used to promote healing while keeping the foot and ankle totally immobile. Often heel pain in children returns after it has been treated because the heel bone is still growing. Recurrence of heel pain may be a sign of calcaneal apophysitis, or it may indicate a different problem. If your child has a repeat bout of heel pain, be sure to make an appointment with your foot and ankle surgeon.
