Sever's disease occurs in children when the growth plate (which is the growing part of the heel) is injured. The foot is one of the first body parts to grow to full size. This usually occurs in early
puberty. During this time, bones often grow faster than muscles and tendons. As a result, muscles and tendons become tight. The heel area is less flexible. During weight-bearing activity (activity
performed while standing), the tight heel tendons may put too much pressure at the back of the heel (where the Achilles tendon attaches). This can injure the heel and cause Sever's disease.
Sever?s is often present at a time of rapid growth in adolescent athletic children. At this time the muscles and tendons become tighter as the bones become larger. Between 8 - 15 years of age is the
usual onset of this condition.
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.
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
Fortunately Severs? disease can be treated and prevented through a number of different techniques that have all proven highly effective. The heel will repair itself even without active treatment
provided that the suffering foot is given a chance to heal. Typically Severs? disease will take 2-8 weeks, although in many cases it can take longer as the continuous growing of the bone can
exacerbate the condition. Podiatrists have an important role in preventing Severs? disease in young athletes, and in treating the condition when it develops so children can get back on their feet as
quickly as possible. Generally treatment involves stretching muscles running down to the heel to relieve tension and pain, these include the hamstrings and calf muscles, and these stretching
exercises will need to be performed at least 2 or 3 times a day. RICE is a classic method of speeding up the recovery of self-healing injuries like Severs? disease. This involves Rest, the
application of Ice to the injury, Compression, and finally Elevation to encourage repaid. These measures can be advised by a trained podiatrist, but it is then up to a child to carry on with regular
Having Sever?s disease does not predispose children or teens to any other condition, nor is it a permanent problem. It is self-limiting, and when treated, the pain and other symptoms will abate
within a few weeks. Once the growth plate has finished growing, Sever?s disease will resolve and won?t recur. It is important to continue to treat any underlying foot conditions and to avoid any long
periods of inactivity.
