Sever’s disease is an injury to a child’s still developing foot structure, specifically an inflammation in the heel’s growth plate due to muscle strain and repetitive stress. It is common in young athletes and children who have problems with pronation. Sever’s Disease usually occurs in children age 8, 14 years of age when the child’s bones are still in the growth stage and the growth plates have not become ossified.
Sever?s disease is directly related to overuse of the bone and tendons in the heel. This can come from playing sports or anything that involves a lot of heel movement. It can be associated with starting a new sport, or the start of a new season. Children who are going through adolescence are also at risk of getting it because the heel bone grows quicker than the leg. Too much weight bearing on the heel can also cause it, as can excessive traction since the bones and tendons are still developing. It occurs more commonly in children who over-pronate, and involves both heels in more than half of patients.
Pain symptoms usually begin after a child begins a new sport or sporting season, and can worsen with athletic activities that involve running and jumping. It is common for a child with Sever?s disease to walk with a limp. Increased activity can lead to heel cord tightness (Achilles Tendon), resulting in pressure on the apophysis of the calcaneus. This will cause irritation of the growth plate and sometimes swelling in the heel area thus producing pain. This usually occurs in the early stages of puberty.
Physical examination varies depending on the severity and length of involvement. Bilateral involvement is present in approximately 60% of cases. Most patients experience pain with deep palpation at the Achilles insertion and pain when performing active toe raises. Forced dorsiflexion of the ankle also proves uncomfortable and is relieved with passive equinus positioning. Swelling may be present but usually is mild. In long-standing cases, the child may have calcaneal enlargement.
Non Surgical Treatment
Orthotics, The orthotics prescribed are made to align the foot in its correct foot posture. This will reduce stress and force at the site of the growth plate of the heel bone. Rest and Ice the heel 20 minutes before and after sporting activity. Calf muscle stretching exercises.
The surgeon may select one or more of the following options to treat calcaneal apophysitis. Reduce activity. The child needs to reduce or stop any activity that causes pain. Support the heel. Temporary shoe inserts or custom orthotic devices may provide support for the heel. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Physical therapy. Stretching or physical therapy modalities are sometimes used to promote healing of the inflamed issue. Immobilization. In some severe cases of pediatric heel pain, a cast may be used to promote healing while keeping the foot and ankle totally immobile. Often heel pain in children returns after it has been treated because the heel bone is still growing. Recurrence of heel pain may be a sign of calcaneal apophysitis, or it may indicate a different problem. If your child has a repeat bout of heel pain, be sure to make an appointment with your foot and ankle surgeon.
