Sever’s disease is a term used to describe inflammation of the calcaneal apophysis which occurs in children and adolescents. Sever first described the condition in 1912. Further studies have suggested that the condition is due to repeated ‘microtrauma’ at the site of the attachment of the Achilles tendon to the apophysis of the heel, often as result of sporting activities. The disorder can be classified among the general osteochondrosis syndromes such as Osgood-Schlatter disease.
Sever’s Disease typically affects boys and girls between 8-15 years of age. Risk factors include. Athletic activity that involves heel contact with hard surfaces, as in gymnastics, track, soccer, basketball, ice skating, ballet and aerobics. The wearing of ill-fitting shoes. Well-made shoes that fit properly are a must for every child. Prolonged periods of standing. If a child complains of heel pain after choir practice, doing dishes, standing in lines or other activities that put pressure on the heel bones, pay attention.
As a parent, you may notice your child limping while walking or running awkwardly. If you ask them to rise onto their tip toes, their heel pain usually increases. Heel pain can be felt in one or both heels in Sever’s disease.
Your Podiatrist or Physiotherapist will assist in diagnosing the injury and the extent of the damage. From this, they will develop a management plan which may include rest or activity modification, soft tissue treatment such as massage and stretching, correction of biomechanics through heel raises or orthoses and the progression through a series of specific strengthening exercises.
Non Surgical Treatment
Initially, treatment will consist of resting from activity, ice and anti-inflammatory medications to reduce the pain. Your physiotherapist may also use a variety of pain reducing techniques such as soft tissue massage or joint mobilisations. They may recommend taping to unload the area of pain, heel cups or wedge inserts into the bottom of your shoe. Also in the initial phase we may also refer you to podiatry for orthotics and/or further footwear recommendations. It is also ideal in the first instance to start stretching your calf muscles and achilles. This initial phase typically lasts for 1-2 weeks. During this time your physiotherapist will guide you on appropriate levels of activity- they may recommend you rest from impact type activities during this phase, and will guide you on the best program to return to your sport without any further injury.
This condition is self limiting, it will go away when the two parts of bony growth join together, this is natural. Unfortunately, Sever’s disease can be very painful and limit sport activity of the child while waiting for it to go away, so treatment is often advised to help relieve it. In a few cases of Sever’s disease, the treatment is not successful and these children will be restricted in their activity levels until the two growth areas join, usually around the age of 16 years. There are no known long term complications associated with Sever’s disease.
