Sever?s disease occurs in children when the growing part of the heel is injured. This growing part is called the growth plate. The foot is one of the first body parts to grow to full size. This usually occurs in early puberty. During this time, bones often grow faster than muscles and tendons. As a result, muscles and tendons become ?tight.? The heel area is less flexible. During weight-bearing activity (activity performed while standing), the tight heel tendons may put too much pressure at the back of the heel (where the Achilles tendon attaches). This may injure the heel.
One of the most common causes of heel pain in adolescents, Sever’s disease is an overuse injury to the growth plate of the calcaneus (heel). It is commonly seen in growing, active children 8-12 years of age. Soccer players, gymnasts, and children who do any sort of running or jumping activity have an increased risk of developing Sever’s disease. Occurring in one or both feet, Sever?s disease occurs at the back of the heel (also known as the apophysis or the insertion of the Achilles tendon).
The most prominent symptom of Sever’s disease is heel pain which is usually aggravated by physical activity such as walking, running or jumping. The pain is localised to the posterior and plantar side of the heel over the calcaneal apophysis. Sometimes, the pain may be so severe that it may cause limping and interfere with physical performance in sports. External appearance of the heel is almost always normal, and signs of local disease such as edema, erythema (redness) are absent. The main diagnostic tool is pain on medial- lateral compression of the calcaneus in the area of growth plate, so called squeeze test. Foot radiographs are usually normal. Therefore the diagnosis of Sever’s disease is primarily clinical.
Sever’s disease is based on the symptoms reported. To confirm the diagnosis, the clinician will examine the heels and ask about the child’s activity level and participation in sports. They may also squeeze the back part of the heel from both sides at the same time to see if doing so causes pain and also ask the child to stand on tiptoes to see if that position causes pain. There may be tightness in the calf muscle, which contributes to tension on the heel. Symptoms are usually worse during or after activity and get better with rest. X-rays generally are not that helpful in diagnosing Sever’s disease, but they may be ordered to rule out other problems, such as fractures. Sever’s disease cannot be seen on an X-ray.
Non Surgical Treatment
Sever?s disease will go away on its own with rest or after heel bone growth is complete, usually within 2 to 8 weeks after the heel pain or discomfort appears. Sever?s disease is not expected to cause long-term problems, though symptoms may linger for up to several years in severe cases. Certain conservative care measures may be helpful in treating this health problem, including avoiding activities that provoke pain or discomfort, elevating the leg while at rest, performing hamstring and calf muscle stretches two to three times per day, undergoing physical therapy, using cold therapy, using an elastic wrap or compression stocking, Avoiding footwear with heel elevation, toe spring, and toe taper, and instead favoring footwear that?s completely flat and widest at the ends of the toes. More aggressive treatment measures, including over-the-counter anti-inflammatory medication (e.g. ibuprofen), steroid injections, and surgery, may be indicated in certain cases. Addressing the footwear component of this health problem is an important part of a well-rounded Sever?s disease treatment plan. Optimal footwear for preventing or treating this problem is flat, wide (widest at the ends of the toes), and flexible in the sole. Open-back footwear (such as certain Crocs models) may be particularly helpful for kids and teens with Sever?s disease.
