Overview
This condition is self limiting, it will go away when the two parts of bony growth join together, this is natural. Unfortunately, Sever's disease can be very painful and limit sport activity of the child while waiting for it to go away, so treatment is often advised to help relieve it. In a few cases of Sever's disease, the treatment is not successful and these children will be restricted in their activity levels until the two growth areas join, usually around the age of 16 years. There are no known long term complications associated with Sever's disease.
Causes
The actual pathology of the condition is one of more of an overuse syndrome in which the growth plate of the heel may become slightly displaced, causing pain. Biopsies of similar conditions have shown changes consistent with separation of the cartilage. The cause of Sever's disease is not entirely clear. It is most likely due to overuse or repeated minor trauma that happens in a lot of sporting activities - the cartilage join between the two parts of the bone can not take all the shear stress of the activities. Some children seem to be just more prone to it for an unknown reason, combine this with sport, especially if its on a hard surface and the risk of getting it increases. A pronated foot and tight calf muscles are common contributing factors. The condition is very similar to Osgood-Schlatters Disease which occurs at the knee.
Symptoms
Pain is reproduced through a gentle squeeze of the back of the heel. Children may present with a limp or ?Bouncy gait?. Pain is worse barefoot and often present in the mornings and post exercise. The pain is located at the back of the heel, with localized swelling of the area.
Diagnosis
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
The practitioner should inform the patient and the patient?s parents that this is not a dangerous disorder and that it will resolve spontaneously as the patient matures (16-18 years old). Treatment depends on the severity of the child?s symptoms. The condition is self-limiting, thus the patient?s activity level should be limited only by pain. Treatment is quite varied. Relative Rest/ Modified rest or cessation of sports. Cryotherapy. Stretching Triceps Surae and strengthen extensors. Nighttime dorsiflexion splints (often used for plantar fasciitis, relieve the symptoms and help to maintain flexibility). Plantar fascial stretching. Gentle mobilizations to the subtalar joint and forefoot area. Heel lifts, Orthoses (all types, heel cups, heel foam), padding for shock absorption or strapping of heel to decrease impact shock. Electrical stimulation in the form of Russian stimulation sine wave modulated at 2500 Hz with a 12 second on time and an 8 second off time with a 3 second ramp. Advise to wear supportive shoes. Ultrasound, nonsteroidal anti-inflammatory drugs. Casting (2-4 weeks) or Crutches (sever cases). Corticosteroid injections are not recommended. Ketoprofen Gel as an addition to treatment. Symptoms usually resolve in a few weeks to 2 months after therapy is initiated. In order to prevent calcaneal apophysitis when returning to sports (after successful treatment and full recovery), icing and stretching after activity are most indicated. Respectable opinion and poorly conducted retrospective case series make up the majority of evidence on this condition. The level of evidence for most of what we purport to know about Sever?s disease is at such a level that prospective, well-designed studies are a necessity to allow any confidence in describing this condition and its treatment.
Exercise
Stretching exercises can help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should do these stretches 2 or 3 times a day. Each stretch should be held for about 20 seconds. Both legs should be stretched, even if the pain is only in 1 heel. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To do this, your child should sit on the floor, keeping his or her hurt leg straight. One end of a bungee cord or piece of rubber tubing is hooked around a table leg. The other end is hitched around the child's toes. The child then scoots back just far enough to stretch the cord. Next, the child slowly bends the foot toward his or her body. When the child cannot bend the foot any closer, he or she slowly points the foot in the opposite direction (toward the table). This exercise (15 repetitions of "foot curling") should be done about 3 times. The child should do this exercise routine a few times daily.
