Sever's disease is an injury to a child's still developing foot structure, specifically an inflammation in the heel's growth plate due to muscle strain and repetitive stress. It is common in young
athletes and children who have problems with pronation. Sever's Disease usually occurs in children age 8, 14 years of age when the child's bones are still in the growth stage and the growth plates
have not become ossified.
The cause of Sever's Disease is not entirely clear but it is most likely due to repeated minor trauma that occurs during high-impact activities that involve running and jumping such as soccer,
basketball, and gymnastics. It may also occur when an active child regularly wears shoes with poor heel padding, shock absorbency, or poor arch support. Some additional contributing factors are
excessive pronation, an overly tight calf muscle, and other flaws in the biomechanics of a child's walking stride. Children who are overweight are also at greater risk of developing Sever's
The symptoms include pain, tenderness, swelling or redness in the heel, and they might have difficulty walking or putting pressure on the heel. If you notice that your child suddenly starts walking
around on their toes because their heels hurt, that?s a dead giveaway. Kids who play sports might also complain of foot pain after a game or practice. As they grow, the muscles and tendons will catch
up and eventually the pressure will subside along with the pain. But in the meantime, it can become very uncomfortable.
The x-ray appearance usually shows the apophysis to be divided into multiple parts. Sometimes a series of small fragments is noted. Asymptomatic heels may also show x-ray findings of resporption,
fragmentation and increased density. But they occur much less often in the normal foot. Pulling or ?traction? of the Achilles tendon on the unossified growth plate is a likely contributing factor to
Sever?s disease. Excessive pronation and a tight Achilles and limited dorsiflexion may also contribute to the development of this condition.
Non Surgical Treatment
Traditional treatment involved simply telling children that they can?t play sport for a year. This is not popular for children or parents and abstaining from sport leads to other problems when
wanting to return. Treatments focus on improving foot and lower limb function with footwear selection, heel raises, calf stretching, prescription orthoses, run technique training and training
modifications. This results in a reduced load through the growth plate and the child can perform more activity before the growth plate becomes inflamed. Rest will always reduce the Sever?s disease
symptoms, however this is always the last option.
Maintain good flexibility through stretching exercises. Avoid excessive running on hard surfaces. Use quality, well-fitting shoes with firm support and a shock-absorbent sole.
