What Causes Severs Disease?

Overview

The calcaneal apophysis is a growth center where the Achilles tendon and the plantar fascia attach to the heel. It first appears in children aged 7 to 8 years. By ages 12 to 14 years the growth center matures and fuses to the heel bone. Injuries can occur from excessive tension on the Achilles tendon and the plantar fascia, or from direct impact on the heel. Excessive stress on this growth center can cause irritation of the heel, also called Sever?s disease.

Causes

Physically active children run the risk of developing Sever?s disease because they put the most strain on their growing bones. Sever?s usually occurs during the adolescent growth spurt, when young people grow most rapidly. (This growth spurt can begin any time between the ages of 8 and 13 for girls and 10 and 15 for boys.) By age 15 the back of the heel usually finished growing. As teens grow, the growth plates harden and the growing bones fuse together into mature bone. Young people engaged in physical activities and sports that involve jumping and running on hard surfaces-such as track, basketball, soccer, and gymnastics-are ata higher risk for developing Sever?s disease. Poor-fitting shoes can contribute by not providing enough support or padding for the feet or by rubbing against the back of the heel.

Symptoms

Most children with Sever’s complain of pain in the heel that occurs during or after activity (typically running or jumping) and is usually relieved by rest. The pain may be worse when wearing cleats. Sixty percent of children’s with Sever’s report experiencing pain in both heels.

Diagnosis

In Sever’s disease, heel pain can be in one or both heels. It usually starts after a child begins a new sports season or a new sport. Your child may walk with a limp. The pain may increase when he or she runs or jumps. He or she may have a tendency to tiptoe. Your child’s heel may hurt if you squeeze both sides toward the very back. This is called the squeeze test. Your doctor may also find that your child’s heel tendons have become tight.

Non Surgical Treatment

Treatment depends on the severity of the condition, but may include relative rest and modified activity, a physiotherapist can help work out what, and how much, activity to undertake. Cold packs, apply ice or cold packs to the back of the heels for around 15 minutes after any physical activity, including walking. Shoe inserts, small heel inserts worn inside the shoes can take some of the traction pressure off the Achilles tendons. This will only be required in the short term. Medication, pain-relieving medication may help in extreme cases, but should always be combined with other treatment and following consultation with your doctor). Anti-inflammatory creams are also an effective management tool. Splinting or casting, in severe cases, it may be necessary to immobilise the lower leg using a splint or cast, but this is rare. Time, generally the pain will ease in one to two weeks, although there may be flare-ups from time to time. Correction of any biomechanical issues, a physiotherapist can identify and discuss any biomechanical issues that may cause or worsen the condition. Education on how to self-manage the symptoms and flare-ups of Sever?s disease is an essential part of the treatment.
