Sever's Disease, otherwise known as calcaneal apophysitis is an inflammation of the growth plate in the heel of growing children, typically adolescents. The condition presents as pain in the heel and
is caused by repetitive stress to the heel and is thus particularly common in active children. It usually resolves once the bone has completed growth or activity is lessened.
A big tendon called the Achilles tendon joins the calf muscle at the back of the leg to the heel. Sever?s disease is thought to occur because of a mismatch in growth of the calf bones to the calf
muscle and Achilles tendon. If the bones grow faster than the muscles, the Achilles tendon that attaches the muscle to the heel gets tight. At the same time, until the cartilage of the calcaneum is
ossified (turned into bone), it is a potential weak spot. The tight calf muscle and Achilles tendon cause a traction injury on this weak spot, resulting in inflammation and pain. Sever?s disease most
commonly affects boys aged ten to 12 years and girls aged nine to 11 years, when growth spurts are beginning. Sever?s disease heals itself with time, so it is known as self-limiting. There is no
evidence to suggest that Sever?s disease causes any long term problems or complications.
Symptoms of calcaneal apophysitis may include pain in the back or bottom of the heel, Limping, walking on toes, difficulty running, jumping, or participating in usual activities or sports. Pain when
the sides of the heel are squeezed.
Radiography. Most of the time radiographs are not helpful because the calcaneal apophysis is frequently fragmented and dense in normal children. But they can be used to exclude other traumas.
Ultrasonography. could show the fragmentation of secondary nucleus of ossification of the calcaneus in severs?s disease. This is a safe diagnostic tool since there is no radiation. This diagnostic
tool can also be used to exclude Achilles tendinitis and/or retrocalcaneal bursitis.
Non Surgical Treatment
In general, management is along the normal lines for sports injuries. Simply telling an individual to give up his or her chosen sport is not satisfactory (this may be a very talented young footballer
who hopes to become a professional). Explain to the child and parent that this is an overuse injury, common in the growing child. It has a good prognosis but it is necessary to ease back on training
for a while to let it recover. Offer to talk to the coach. If the parent and coach are one and the same, beware that the child is being 'pushed' too hard. During abstinence from normal training,
cardiovascular fitness can be maintained by non-weight-bearing exercise such as swimming or cycling.
Perform a well rounded dynamic warm up before activity. Perform a good static stretching routine after activity. Increase core strength. Perform exercises that emphasize active lengthening of the
calf muscles. Use proper footwear. Avoid excessive running or jumping on hard surfaces like concrete by using better surfaces such as asphalt, gymnasium floors or grass.
