Sever?s Disease is often misdiagnosed as a simple growing pains and affects boys far more often than girls, especially between the ages of 8 and 14. It is extremely common in children that play Soccer, Basketball, And Hockey. However it is not limited to these sports alone, nor is it simply a pre-season type condition related to fitness. Sever?s Disease sounds terrible, but there is no need to panic as it is not a contagious or incurable condition. In children, there is a growth plate in the heel bone, which at puberty becomes solid and forms part of the heel, however prior to puberty it can cause pain if the child?s foot rolls inwards or outwards too much, causing increased stress on this growth plate and inturn causes pain.
The heel bone sometimes grows faster than the leg muscles (including the calf muscles) and tendons (including the Achilles tendon) during the early puberty growth spurt. The different growth rate in these structures can cause lower leg muscles and tendons to become overstretched and tight, which makes the heel less flexible and puts excessive pressure on the heel growth plate. The Achilles tendon, the strongest tendon in the body, attaches to the heel growth plate, and repetitive stress on this structure, especially if it?s already tight, can damage the growth plate, leading to tenderness, swelling, and pain. Activities that involve running or jumping, such as soccer, gymnastics, track, and basketball, can place significant stress on a tight Achilles tendon and contribute to the onset of Sever?s disease. Ill-fitting shoes can also contribute to this health problem by failing to provide the right kind of support or by rubbing against the back of heel. The following factors may increase the likelihood of Sever?s disease in kids or young teens. Wearing footwear that is too narrow in the toe box. Leg length inequality. Obesity or carrying excess bodyweight. Excessive foot and ankle pronation.
On examination, the typical signs are tenderness on palpation of the heel, particularly on deep palpation at the Achilles tendon insertion. Pain on dorsiflexion of the ankle, particularly when doing active toe raises; forced dorsiflexion of the ankle is also uncomfortable. Swelling of the heel, usually mild. Calcaneal enlargement, in long-standing cases.
Sever?s disease can be diagnosed based on the symptoms your child has. Your child?s doctor will conduct a physical examination by squeezing different parts of your child?s foot to see if they cause any pain. An X-ray may be used to rule out other problems, such as a broken bone or fracture.
Non Surgical Treatment
Management consists of explanation of what's happening and advice on activity modification to get it to settle. Icing after activity and heating during breaks in activity also often help. Local treatment with electrotherapy may be indicated in the acute stage or to help settle pain for a specific activity/competition. Stretches will be advised and the child may require orthotics to control foot position. A heel raise or heel cups may also help. Strapping may be of some benefit. The mainstay of treatment however is the icing and activity modification and reassurance that the condition is self-limiting, this may take up to 2 years.
Sever?s disease is self-recovering, meaning that it will go away on its own when sport is reduced or as the bones mature. The condition is not expected to create any long-term disability, and expected to subside in 2-8 weeks. However, while the disease does subside quickly, it can recur, for example at the start of a new sports season or during a growth spurt. If your pain does return you will need to re-introduce the above treatment plan. If the pain persists please seek further advice from your GP.
