During AGS, and in specific reference to Sever?s disease, the heel bone grows faster than the Achilles tendon, resulting in an extremely tight Achilles tendon. Because the foot is one of the first parts of the body to grow to full size, and because the heel is not a very flexible area, it is especially susceptible to injury. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (such as impact activities) on the tight Achilles tendon causes the tendon to pull on and damage the growth plate in the heel, resulting in swelling, tenderness, and pain.
Inflammation occurs at the insertion of the achilles tendon into the back of the heel due to a number of reasons. One or several of the following may cause the initiation of Sever?s disease. Rapid growth spurt. Tight calf muscles. Change in footwear (soccer boots / athletic shoes no heel). Excessive rolling in of feet. Poor warm up routine. Remember this condition usually settles as the growth plate fuses within 6-12 months.
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.
A Podiatrist can easily evaluate your child?s foot, lower limbs and muscular flexibility, to identify if a problem exists. If a problem is identified, a simple treatment plan is put in place. Initial treatment may involve using temporary padding and strapping to control motion or to cushion the painful area and based on the success of this treatment, a long-term treatment plan will be put in place. This long-term treatment plan may or may not involve Foot Supports, Heel Raises, muscle stretching and or strengthening.
Non Surgical Treatment
Treatment depends on the severity of the condition, but may include relative rest and modified activity, a physiotherapist can help work out what, and how much, activity to undertake. Cold packs, apply ice or cold packs to the back of the heels for around 15 minutes after any physical activity, including walking. Shoe inserts, small heel inserts worn inside the shoes can take some of the traction pressure off the Achilles tendons. This will only be required in the short term. Medication, pain-relieving medication may help in extreme cases, but should always be combined with other treatment and following consultation with your doctor). Anti-inflammatory creams are also an effective management tool. Splinting or casting, in severe cases, it may be necessary to immobilise the lower leg using a splint or cast, but this is rare. Time, generally the pain will ease in one to two weeks, although there may be flare-ups from time to time. Correction of any biomechanical issues, a physiotherapist can identify and discuss any biomechanical issues that may cause or worsen the condition. Education on how to self-manage the symptoms and flare-ups of Sever?s disease is an essential part of the treatment.
One of the most important things to know about Sever’s disease is that, with proper care, the condition usually goes away within 2 weeks to 2 months and does not cause any problems later in life. The sooner Sever’s disease is addressed, the quicker recovery is. Most kids can return to physical activity without any trouble once the pain and other symptoms go away.
