A syndrome of heel pain in skeletally immature individuals. The formal name is: calcaneal apophysitis. The pain is thought to arise from the growth plate (apophysis) and epiphysis. It is thought to be an overuse phenomena. Overloading of the apophysis by both traction (due to Achilles tendon) and compression (sue to weightbearing) have been implicated. Reversible pathologic alterations occur in the apophysis, which cause secondary pain. It is the growth plate and its bone, at the back of the heel bone (calcaneus), whose presence allows for longitudinal growth of calcaneus.
There are many contributing factors that cause strain across the growth plate, making your child prone to developing Sever?s disease. These include repeated minor trauma to the growth plate from running or jumping sports, tight calf or hamstring muscles, rapid growth spurts can lead to the leg muscles becoming tight, increasing tension on the growth plate, tight Achilles tendon, the Achilles tendon attaches to the back of the heel adjacent to the growth plate, poor foot posture, may increase the strain on the growth plate, footwear with a very low heel pitch (eg soccer boots), unsupportive or unstable footwear with poor shock absorption at the heel, running or playing sport on hard surfaces.
This syndrome can occur unilaterally or bilaterally. The incidence of bilaterally is approximately 60%. Common signs and symptoms include posterior inferior heel pain (over the medial and lateral surface of the bone). Pain is usually absent when the child gets up in the morning. Increased pain with weight bearing, running or jumping (= activity-related pain). The area often feels stiff. The child may limp at the end of physical activity. Tenderness at the insertion of the tendons (= an avascular necrosis of the arthropathy). Limited ankle dorsiflexion range secondary to tightness of the Achilles tendon. Hard surfaces and poor-quality or worn-out athletic shoes contribute to increased symptoms. The pain gradually resolves with rest. Reliability or validity of methods used to obtain the ankle joint dorsiflexion or biomechanical malalignment data are not commented upon, thus reducing the quality of the data. Although pain and limping are mentioned as symptomatic traits, there have been no attempts to quantify the pain or its effect on the individual.
Sever's disease is diagnosed based on a doctor?s physical examination of the lower leg, ankle, and foot. If the diagnosis is in question, the doctor may order X-rays or an MRI to determine if there are other injuries that may be causing the heel pain.
Non Surgical Treatment
Treatment may consist of one or more of the following, Elevating the heel, Stretching hamstring and calf muscles 2-3 times daily, Using R.I.C.E. (Rest, Ice, Compression, Elevation), Foot orthotics, Medication, Physical therapy, Icing daily (morning), Heating therapy, Open back shoe are best and avoid high heel shoe. The Strickland Protocol has shown a positive response in patients with a mean return to sport in less than 3 weeks.
