Heel bone growth

Between the heel bone and the instep a strong ligament, the plantar fascia, stretches. This ligament works like the string of a bow, flexibly stretching under pressure, thus reducing and supporting the body weight. The plantar fascia forms an articulated structure together with the Achilles tendon, pivoting on the heel bone. For this reason, the stretching of both the plantar fascia and the Achilles tendon have an effect on the heel bone.
With flat foot, the constant pulling of the plantar fascia affects the heel bone from the direction of the sole. This results in periostitis where the ligament joins the bone, which if persistent induces a spur-like bone formation, heel bone growth. The stretching of the ligament on the sole and its painful inflammation is called plantar fasciitis. It is important to understand that the heel bone thorn is a secondary effect caused by the overstretching.

• Treatment
  To get rid of the spur, an orthotic insole with a hole is prescribed, thus relieving the area of the periosteum under pressure. If it causes periostitis, a compress, rest and medication to reduce inflammation are justified. Operations are very rare.
