Overview
It is thought to be a traction injury, where the Achilles tendon and Plantar fascia pull in opposite directions. Sever?s occurs in children aged 8 to 16 years old. In children, the heel bone is made up of 2 bones, with a growth plate of cartilage in between the sections, holding these 2 bones together. As the cartilage expands, the edges of it eventually turn to bone, and finally the gap closes. This usually occurs within the first 13-15 years of life. However, because these bones are connected by cartilage they are weaker than normal bones. This is why they are very vulnerable to injury.
Causes
Having flatfeet or very pronated feet can make one prone to Sever’s disease. But also patient?s that have a very high arch foot structure tend to have a very high shock and high impact heel strike. This also puts extra stress on the heel and apophysis.
Symptoms
The most common symptoms of Sever?s involves pain or tenderness in one or both heels. This pain usually occurs at the back of the heel, but can also extend to the sides and bottom of the heel. A child with Sever?s may also have these common problems. Heel pain with limping, especially after running. Difficulty walking. Discomfort or stiffness in the feet upon awaking. Swelling and redness in the heel. Symptoms are usually worse during or after activity and get better with rest.
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
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: 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: Education on how to self-manage the symptoms and flare-ups of Sever?s disease is an essential part of the treatment.
Prevention
Prevention consists of maintaining good flexibility through stretching exercises, avoid excessive running on hard surfaces, and use quality, well-fitting shoes with firm support and a shock-absorbent sole.
