Sever's disease is a disorder that commonly occurs in active children between the ages of 9 and 13 years of age. Even though it is misnamed as a disease, it is actually a self-limiting disorder that
occurs around the growth plate in the back of the heel. The Achilles tendon attaches to the upper portion of the heel growth plate. On the bottom of the growth plate is an attachment of a ligament
known as the plantar fascia. With increased activity, there is a pulling or tugging that occurs on this growth plate, and a portion of the growth plate is being pulled away from its attachment to the
heel. X-rays are often taken to verify the position and location of this growth plate.
Sever's Disease is a repetitive strain injury caused by the following. High impact injury activities and sport like netball, football, soccer, hockey, basketball, running, jumping and tennis. Tight
calf muscles. Poor mechanics, structure and function of the foot. Excessive pronation. Rapid growth spurt. The above causes tension, inflammation and pain where the Achilles tendon inserts onto the
calcaneus (Back/bottom surface of the heel bone). It is important that this problem is treated and monitored until the growth plate ossifies in the heel. This could occur between the ages of 14 and
16 years of age. In extreme cases the growth plate can become separated from the calcaneus.
Patients with Severs disease typically experience pain that develops gradually in the back of the heel or Achilles region. In less severe cases, patients may only experience an ache or stiffness in
the heel that increases with rest (especially at night or first thing in the morning). This typically occurs following activities which require strong or repetitive contraction of the calf muscles,
such as running (especially uphill) or during sports involving running, jumping or hopping. The pain associated with this condition may also warm up with activity in the initial stages of the
condition. As the condition progresses, patients may experience symptoms that increase during activity and affect performance. Pain may also increase when performing a calf stretch or heel raise
(i.e. rising up onto tip toes). In severe cases, patients may walk with a limp, have difficulty putting their heel down, or be unable to weight bear on the affected leg. Pain may also increase on
firmly touching the affected region and occasionally a bony lump may be palpable or visible at the back of the heel. This condition typically presents gradually overtime and can affect either one or
both lower limbs.
Sever condition is diagnosed by detecting the characteristic symptoms and signs above in the older children, particularly boys between 8 and 15 years of age. Sometimes X-ray testing can be helpful as
it can occasionally demonstrate irregularity of the calcaneus bone at the point where the Achilles tendon attaches.
Non Surgical Treatment
The good news is that the condition doesn?t cause any long-term foot problems. Symptoms typically go away after a few months. The best treatment is simply rest. Your child will need to stop or cut
down on sports until the pain gets better. When she's well enough to return to her sport, have her build up her playing time gradually. Your doctor may also recommend ice packs or nonsteroidal
anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, to relieve the pain. Supportive shoes and inserts that reduce stress on the heel bone. These can help if your child has another foot
problem that aggravates Sever?s disease, such as flat feet or high arches. Stretching and strengthening exercises, perhaps with the help of a physical therapist. In severe cases, your child may need
a cast so her heel is forced to rest.
