Sever?s disease, also known as calcaneal apophysitis or Osgood-Schlatter syndrome of the foot. This traction apophysitis is secondary to repetitive microtraumata or overuse of the heel in young
athletes. The calcaneus is situated at the most plantar posterior aspect of the foot. The Achilles tendon inserts to the lower, posterior and slightly medial aspect of the calcaneus. The plantar
fascia originates from the medial tubercle on the plantar aspect of the calcaneus. Proximal to the epiphysis is the apophysis, where the Achilles tendon actually inserts. The calcaneal growth plate
and apophysis are situated in an area subject to high stress from the plantar and Achilles tendon.
The more active a child is then the greater the chance of suffering from Sever?s disease. Poor foot function such as flat feet causes the calf and Achilles to work harder and pull on the growth plate
leading to Sever?s disease. Tight calves or Achilles is common in growing children and can increase tension on the growth plate.
The most obvious sign of Sever's disease is pain or tenderness in one or both heels, usually at the back. The pain also might extend to the sides and bottom of the heel, ending near the arch of the
foot. A child also may have these related problems, swelling and redness in the heel, difficulty walking, discomfort or stiffness in the feet upon awaking, discomfort when the heel is squeezed on
both sides, an unusual walk, such as walking with a limp or on tiptoes to avoid putting pressure on the heel. Symptoms are usually worse during or after activity and get better with rest.
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
Massage the calves gently from the knee to the heel, being especially careful around the Achilles? tendon, as this will be extremely tight and tender. During this massage, flex and point the foot
through normal pain-free ranges of motion to increase flexibility while massaging. Massage every other or every third day, making sure your young athlete is not still sore before massaging again. If
you?re unsure how to massage, find someone in your area that uses Graston technique or Active Release Therapy for best results. Stretch your athlete?s calves. This is the most overlooked aspect of
treatment for Sever?s Disease and this needs to be done every day after practice, and when first starting we recommend 2-3 times per day, allowing gravity to pull heel down, never forcing the
stretch. Ice your heels, but don?t just put an ice pack there. Use a cold water soak to fully immerse the foot and calves up to the knee. We recommend using a rubbermaid can found here. Soak for
10-15 minutes. The water does not have to be frigid, just cold. Use cold water from the tap, insert the foot, then add some ice to help bring down the temperature. When your athlete is experiencing
pain, ice every hour, on the hour, for as many times as possible in one day. Make sure the heel/calves are body temperature before beginning again. Support the arches. This is what has been shown in
studies to reduce pain in young athletes with Sever?s Disease. If you miss out on this one, you miss out on relieving your athletes pain.
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.
