This is generally a self-limiting process which occurs in the calcaneus at the insertion of the achilles tendon in active adolescents. This is more common in boys than in girls, and is frequently due to jumping or other activities. This is a problem that occurs because the tendon puts pressure on the growth plate, which then causes irritation in the apophysis in the heel. This can lead to soreness and irritation. Most of these problems will do well with conservative measures including activity modification and heel cord stretching. Once growth has been completed, the symptoms will generally resolve.
In most cases the patients may continue with activities as tolerated, although they may need to rest if symptoms increase. Physical therapy can also be helpful. If symptoms become severe, then a trial of crutches and rest or possibly even a cast is occasionally necessary.
