Living With Severs Disease
Sever?s Disease (calcaneal aphophysitis) is not really a disease, but more a repetitious strain injury. This is the most common cause of kids heel pain seen at Podiatry Care. Active children in football, soccer, basketball, netball and tennis with this type of foot pain complain of pain in the region of the heel bone particularly after exercise. In severe cases, children will complain of pain during exercise as well. It is a frequent cause of heel pain in children, particularly in the very active child. It is most often seen in children between the ages of 8 to 15 years as the growth plate is not fully developed or calcified at this time.
Predisposing Hereditary Factors: These are a biomechanical defect that one may be born with, which increases the chances of developing Sever's Disease. Short Achilles Tendon, When the Achilles Tendon is short from birth, it will exaggerate the tightness of this tendon that occurs during a child's growing years. This makes the pull of the Achilles Tendon on the heel's growth plate more forceful than normal, causing inflammation and pain, and eventually Sever's Disease. Short Leg Syndrome, When one leg is shorter than the other, the foot on the short leg must plantar flex (the foot and toes bend down) in order to reach the ground. In this way, the body tries to equalize the length of the legs. In order for the foot to plantar flex, the Achilles Tendon must pull on the heel with greater force than if the leg was a normal length. Thus the heel on the short leg will be more susceptible to Sever's Disease during the foot's growing years. Pronation. Is a biomechanical defect of the foot that involves a rolling outward of the foot at the ankle, so that when walking, the inner side of the heel and foot bears more of the body's weight than is normal (click here for more information about pronation). Pronation thus causes the heel to be tilted or twisted. In order for the Achilles Tendon to attach to the heel, it must twist to reach its normal attachment site. This will shorten or tighten the Achilles Tendon and increase the force of its pull on the heel's growth plate. This will increase the tightness of the Achilles Tendon during the foot's growing years, and may help to initiate bouts of Sever's Disease. Flat Arches and High Arches. Both of these biomechanical foot defects effect the pitch, or angle of the heel within the foot. When the heel is not positioned normally within the foot due to the height of the arch, the Achilles Tendon's attachment to the heel is affected. This may produce a shortening or tightening of the Achilles Tendon, which increases the force of its pull on the heel's growth plate. During the foot's growing years, abnormal arch height may contribute to the onset of Sever's Disease.
The patient complains of activity related pain that usually settles with rest. On Examination the heel bone - or calcaneum - is tender on one or both sides. The gastrocnemius and soleus muscles (calf muscles) may be tight and bending of the ankle might be limited because of that. Foot pronation (rolling in) often exacerbates the problem. There is rarely anything to see and with no redness or swelling and a pain that comes and goes mum and dad often wait before seeking advice on this condition. The pain may come on partway through a game and get worse or come at the end of the game. Initially pain will be related only to activity but as it gets worse the soreness will still be there the next morning and the child might limp on first getting up.
A doctor How can we increase our height? usually tell that a child has Sever's disease based on the symptoms reported. To confirm the diagnosis, the doctor will probably examine the heels and ask about the child's activity level and participation in sports. The doctor might also use the squeeze test, squeezing the back part of the heel from both sides at the same time to see if doing so causes pain. The doctor might also ask the child to stand on tiptoes to see if that position causes pain. Although imaging tests such as X-rays generally are not that helpful in diagnosing Sever's disease, some doctors order them to rule out other problems, such as fractures. Sever's disease cannot be seen on an X-ray.
Non Surgical Treatment
Your child may need to change or stop doing the activities that cause pain until the growth plate heals. Your child needs to wear shoes with good padding in the heels and good arch support. Special shoes or shoe inserts may help. Pain from Sever's disease may last weeks to months. The pain may come back if your child returns to sports or strenuous activities too soon.
