Children with Sever's disease, which is also called calcaneal apophysitis, develop microfractures where the Achilles tendon inserts on the calcaneus, the large bone that makes up the heel of the foot. These microfractures cause pain, which can vary depending on the type of activity your child is doing, and is generally worse after activity and improves with rest. Sever's disease is more common in boys and typically occurs when a child is between 8 and 13 years old. Although it can affect both heels, it more commonly just affects one foot.
Overuse and stress on the heel bone through participation in sports is a major cause of calcaneal apophysitis. The heel?s growth plate is sensitive to repeated running and pounding on hard surfaces, resulting in muscle strain and inflamed tissue. For this reason, children and adolescents involved in soccer, track, or basketball are especially vulnerable. Other potential causes of calcaneal apophysitis include obesity, a tight Achilles tendon, and biomechanical problems such as flatfoot or a high-arched foot.
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.
A Podiatrist can easily evaluate your child?s foot, lower limbs and muscular flexibility, to identify if a problem exists. If a problem is identified, a simple treatment plan is put in place. Initial treatment may involve using temporary padding and strapping to control motion or to cushion the painful area and based on the success of this treatment, a long-term treatment plan will be put in place. This long-term treatment plan may or may not involve Foot Supports, Heel Raises, muscle stretching and or strengthening.
Non Surgical Treatment
The immediate goal of treatment is pain relief. Because symptoms generally worsen with activity, the main treatment for Sever's disease is rest, which helps to relieve pressure on the heel bone, decreasing swelling and reducing pain. As directed by the doctor, a child should cut down on or avoid all activities that cause pain until all symptoms are gone, especially running barefoot or on hard surfaces because hard impact on the feet can worsen pain and inflammation. The child might be able to do things that do not put pressure on the heel, such as swimming and biking, but check with a doctor first.
One of the most important things to know about Sever's disease is that, with proper care, the condition usually goes away within 2 weeks to 2 months and does not cause any problems later in life. The sooner Sever's disease is addressed, the quicker recovery is. Most kids can return to physical activity without any trouble once the pain and other symptoms go away. Although Sever's disease generally heals quickly, it can recur if long-term measures are not taken to protect the heel during a child's growing years. One of the most important is to make sure that kids wear proper shoes. Good quality, well-fitting shoes with shock-absorbent (padded) soles help to reduce pressure on the heel. The doctor may also recommend shoes with open backs, such as sandals or clogs, that do not rub on the back of the heel. Shoes that are heavy or have high heels should be avoided. Other preventive measures include continued stretching exercises and icing of the affected heel after activity.
