Calcaneal Apophysitis Physiotherapy

Overview

Sever?s is described as a traction apophysitis. In childhood our bones are made of a cartilage mould of the bone, which over time as we grow slowly turns into a full bone. The reason for this is that it is easier to grow cartilage to the length required, and then back fill with bone later than it is to actually grow new bone. Most bones have a least two growth of bone centres, one by the joint and one making the main body of the bone. In the growing heel bone (calcaneus) the posterior part has a separate growth area where the Achilles tendon attaches. When playing lots of sport, especially football, rugby and hockey, the two areas of bone can be pulled apart, producing pain. Recent evidence has also suggested that the appearance of this condition on MRI (magnetic resonance imaging), appears to indicate that Sever?s is a type of stress fracture. Whether that fatigue stress is from compression or tension remains in debate, and is probably a combination of both.

Causes

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.

Symptoms

If your child is suffering from this disease they will be experiencing pain and tenderness in the back of their foot. This soreness can also extend to the sides of the feet. Other sure signs of this disorder include swelling and sensitivity to touch. Because of the amount of discomfort, your child may find it difficult to walk or run. Pay attention to the way your child is walking. If you notice unusual posture or abnormal gait they may be avoiding placing pressure on the heel. These symptoms typically become apparent during activity and exercise or directly following it. If your child is indicating pain in their heel, schedule an appointment with us today.

Diagnosis

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

Activity Modification: to decrease the pain, limiting sporting activities is essential. Cutting back on the duration, intensity, and frequency can significantly improve symptoms. Heel cord stretching is important if heel cord tightness is present. Heel cushions/cups or soft orthotics decreases the impact on the calcaneus by distributing and cushioning the weight bearing of the heel. Use of NSAIDS. Ibuprofen (Nuprin, Motrin) or naproxen (Aleve) can decrease pain and secondary swelling. Ice. Placing cold or ice packs onto the painful heel can alleviate pain. Short-leg cast. For recalcitrant symptoms a short-leg cast is occasionally used to force rest the heel.
