Pain in the heel of a child's foot, typically brought on by some form of injury or trauma, is sometimes Sever's Disease. The disease often mimics Achilles tendonitis, an inflammation of the tendon attached to the back of the heel. A tight Achilles tendon may contribute to Sever's Disease by pulling excessively on the growth plate of the heel bone. This condition is most common in younger children and is frequently seen in the active soccer, football or baseball player. Sport shoes with cleats are also known to aggravate the condition. Treatment includes calf muscle stretching exercises, heel cushions in the shoes, and/or anti-inflammatory medications. Consult your physician before taking any medications.
There are usually two root causes of Sever?s disease that we?ve found that effect young athletes. Arches are not supported causing a dysfunctional run, jump, and landing. The calves (gastrocnemius and soleus muscles) are overworked, tight, and do not allow proper movement of foot which puts extreme pressure on the Achilles? tendon, in turn irritating the growth plate in the heel.
Chief complaint is heel pain which increases pain during running and jumping activities. Pain is localized to the very posterior aspect of the heel. Pain is elicited only with weightbearing. Mild involvement is present if pain is brought on only with running during sports. The symptoms can be severe, with pain (and possibly limp) with activities of daily living (ie walking).
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
Fortunately Severs? disease can be treated and prevented through a number of different techniques that have all proven highly effective. The heel will repair itself even without active treatment provided that the suffering foot is given a chance to heal. Typically Severs? disease will take 2-8 weeks, although in many cases it can take longer as the continuous growing of the bone can exacerbate the condition. Podiatrists have an important role in preventing Severs? disease in young athletes, and in treating the condition when it develops so children can get back on their feet as quickly as possible. Generally treatment involves stretching muscles running down to the heel to relieve tension and pain, these include the hamstrings and calf muscles, and these stretching exercises will need to be performed at least 2 or 3 times a day. RICE is a classic method of speeding up the recovery of self-healing injuries like Severs? disease. This involves Rest, the application of Ice to the injury, Compression, and finally Elevation to encourage repaid. These measures can be advised by a trained podiatrist, but it is then up to a child to carry on with regular RICE.
The following exercises are commonly prescribed to patients with Severs disease. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 1 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate, advanced and other exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head as far as you can go without pain and provided you feel no more than a mild to moderate stretch in the back of your calf, Achilles tendon or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Calf Stretch with Towel. Begin this exercise with a resistance band around your foot and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free. Once you can perform 20 repetitions consistently without pain, the exercise can be progressed by gradually increasing the resistance of the band provided there is no increase in symptoms. Bridging. Begin this exercise lying on your back in the position demonstrated. Slowly lift your bottom pushing through your feet, until your knees, hips and shoulders are in a straight line. Tighten your bottom muscles (gluteals) as you do this. Hold for 2 seconds then slowly lower your bottom back down. Repeat 10 times provided the exercise is pain free.
