Also known as calcaneal apophysitis, Severs? disease is a condition that primarily affects children between the ages of 7 and 15. The condition is typified by pain in the heel which can affect
movement, and as a foot condition, comes under the care of podiatrists. Podiatrists are specially trained professionals who specialise in any and all ailments of the foot and ankle. Podiatrists
dealing with Severs? disease are typically podopaediatricians, individuals who have received training in the delivery of childhood care.
Sever's disease can result from standing too long, which puts constant pressure on the heel. Poor-fitting shoes can contribute to the condition by not providing enough support or padding for the feet
or by rubbing against the back of the heel. Although Sever's disease can occur in any child, these conditions increase the chances of it happening. Pronated foot (a foot that rolls in at the ankle
when walking), which causes tightness and twisting of the Achilles tendon, thus increasing its pull on the heel's growth plate. Flat or high arch, which affects the angle of the heel within the foot,
causing tightness and shortening of the Achilles tendon. Short leg syndrome (one leg is shorter than the other), which causes the foot on the short leg to bend downward to reach the ground, pulling
on the Achilles tendon. Overweight or obesity, which puts weight-related pressure on the growth plate.
The pain is at the heel or around the Achilles tendon. This is felt commonly during exercise, particularly activities involving running or jumping. The back of the heel may also be tender to touch
and there may be localised swelling. There may be stiffness in the calf muscles first thing in the morning and you may notice limping or a tendency to tiptoe.
Low-grade inflammation of the calcaneal apophysis cannot be seen on x-ray. Therefore, although x-rays are often done to rule out bony injuries in children with Sever's disease these x-rays are
usually normal. Advanced Sever's disease can be seen on x-ray but usually the problem is treated before it reaches this point. Other diagnostic tests, such as bone scans or MRI's, are not usually
required in typical cases of Sever's disease. These, or other tests, may be required to rule out other conditions, such as stress fractures of the calcaneus or other bony abnormalities that can mimic
Non Surgical Treatment
Treatment may consist of one or more of the following. Elevating the heel. Stretching hamstring and calf muscles 2-3 times daily. Using R.I.C.E. (Rest, Ice, Compression, Elevation). Foot orthotics.
Medication. Physical therapy. Icing daily (morning). Heating therapy. Open back shoe are best and avoid high heel shoe. The Strickland Protocol has shown a positive response in patients with a mean
return to sport in less than 3 weeks. Further research into the anatomical and biomechanical responses of this protocol are currently being undertaken.
