OverviewSever?s disease is the most common cause of heel pain in children aged 9 to 14. Sever?s disease results from stress placed on the growth plate of the heel bone. An excessive amount of running or other activities can cause inflammation around the growth plate, which results in pain. Rest, ice and orthotics and proper shoes are usually prescribed.
CausesThe 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.
SymptomsSever?s is recognized by pain in the back and lower regions of the heel. It usually starts during or immediately following the child's growth spurt, and/or in very active individuals. The child will usually have pain during or following participation in sport, and will often be seen limping off the field or court. Symptoms of Sever's include painful heel, no swelling or warmth, night pain is absent, pain is worse with increased activity, pain which is usually relieved by rest. Children often hobble or limp from the sports field.
DiagnosisYour 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 TreatmentStretching programs. Strengthening exercises. Exercise and training modification. Orthotic therapy. In rare cases, where fragmentation of the apophysis exists and pain fails to subside with traditional treatments then immobilization of the foot and ankle with a short leg pneumatic walker(walking cast) is indicated.
RecoveryWith proper care, your child should feel better within 2 weeks to 2 months. Your child can start playing sports again only when the heel pain is gone. Your doctor will let you know when physical activity is safe.
