Sever?s disease is irritation of the growth plate in the heel. If rest is prescribed by your doctor, you should probably listen! But, there is usually an underlying cause of this irritation, and we need to address what?s causing it if we don?t want it to come back the first time an athlete jumps, runs, or kicks a ball.
When a baby is born, most of the bones are still cartilage with only some starting to develop into bone. When the heel (calcaneus) starts to develop bone, there is generally one large area of development that starts in the center of the cartilage heel. This area of bone spreads to 'fill up' the cartilage. Another area of bone development (ossification) occurs at the back of the heel bone. These two areas of developing bone will have an area of cartilage between them, this is how the bone grows in size. At around age 16, when growth is nearly complete, these two bony areas fuse together. Sever's disease or calcaneal apophysitis is usually considered to be due to damage or a disturbance in this area of growth.
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
Depending on the underlying cause, treatment can include. Arch supports (foot orthoses) to correctly support the feet. Proper taping of the foot and heel. Rest from activities. Icing at the end of the day. A night splint worn at night. Flexibility exercises and strengthening. Ultrasound therapy. Anti-inflammatory drugs.
The surgeon may select one or more of the following options to treat calcaneal apophysitis. Reduce activity. The child needs to reduce or stop any activity that causes pain. Support the heel. Temporary shoe inserts or custom orthotic devices may provide support for the heel. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Physical therapy. Stretching or physical therapy modalities are sometimes used to promote healing of the inflamed issue. Immobilization. In some severe cases of pediatric heel pain, a cast may be used to promote healing while keeping the foot and ankle totally immobile. Often heel pain in children returns after it has been treated because the heel bone is still growing. Recurrence of heel pain may be a sign of calcaneal apophysitis, or it may indicate a different problem. If your child has a repeat bout of heel pain, be sure to make an appointment with your foot and ankle surgeon.
