Sever's disease is a pain that occurs in the back of the heel of physically active children at around the time of puberty. Sever's disease occurs due to an inflammation of the growth plate due to excessive pull of the achilles tendon on this growth plate. During puberty the bones quite often grow faster than the muscles and tendons causing the tendons to become tight, this tightness then results in excessive pull on the back of the heel resulting in this painful condition.
The heel bone grows faster than the ligaments in the leg. As a result, muscles and tendons can become very tight and overstretched in children who are going through growth spurts. The heel is especially susceptible to injury since the foot is one of the first parts of the body to grow to full size and the heel area is not very flexible. Sever?s disease occurs as a result of repetitive stress on the Achilles tendon. Over time, this constant pressure on the already tight heel cord can damage the growth plate, causing pain and inflammation. Such stress and pressure can result from sports that involve running and jumping on hard surfaces (track, basketball and gymnastics). Standing too long, which puts constant pressure on the heel. Poor-fitting shoes that don?t provide enough support or padding for the feet. Overuse or exercising too much can also cause Sever?s disease.
The main symptom of sever's disease is pain and tenderness at the back of the heel which is made worse with physical activity. Tenderness will be felt especially if you press in or give the back of the heel a squeeze from the sides. There may be a lump over the painful area. Another sign is tight calf muscles resulting with reduced range of motion at the ankle. Pain may go away after a period of rest from sporting activities only to return when the young person goes back to training.
You may have pain when your doctor squeezes your heel bone. You may have pain when asked to stand or walk on your toes or on your heels. You may have pain in your heel when your doctor stretches your calf muscles. Your doctor may order x-rays of the injured foot to show an active growth plate.
Non Surgical Treatment
Treatment may consist of one or more of the following, Elevating the heel, Stretching hamstring and calf muscles 2-3 times daily, Using R.I.C.E. (Rest, Ice, Compression, Elevation), Foot orthotics, Medication, Physical therapy, Icing daily (morning), Heating therapy, Open back shoe are best and avoid high heel shoe. The Strickland Protocol has shown a positive response in patients with a mean return to sport in less than 3 weeks.
To prevent recurrence, patients, parents, coaches, and trainers should be instructed regarding a good preexercise stretching program for the child. Early in the season, encouragement should be given for a preseason conditioning and stretching program. Coaches and trainers should be educated about recognition of the clinical symptoms so they are able to initiate early protective measures and seek medical referral when necessary.
