Why does excess bone sometimes grow on the heel bone?
The growth of excess bone on the heel bone, also known as a heel spur, is primarily caused by repetitive strain or trauma to the heel. Here's why it occurs:
1. Plantar Fasciitis:
- Heel spurs are commonly associated with plantar fasciitis, which is the inflammation of the thick band of tissue (plantar fascia) that connects the heel bone to the toes.
- Chronic inflammation and overuse of the plantar fascia can lead to the build-up of calcium deposits on the heel bone, resulting in the formation of a heel spur.
2. Repetitive Stress:
- Engaging in activities that involve repeated pressure on the heel, such as running, jumping, or prolonged standing, can strain the plantar fascia and the surrounding tissues.
- This chronic stress can lead to the development of a heel spur as the body attempts to reinforce the area by producing extra bone growth.
3. Biomechanical Abnormalities:
- Certain foot structures or abnormalities, such as flat feet or high arches, can alter the way weight is distributed across the foot, leading to excessive strain on the heel.
- This abnormal biomechanics can contribute to the formation of a heel spur.
4. Age-Related Changes:
- As we age, our bodies produce less collagen, a protein that helps to maintain bone strength and flexibility.
- The reduced production of collagen can make the plantar fascia more susceptible to strain and damage, increasing the risk of heel spur formation.
5. Obesity:
- Being overweight or obese puts extra pressure on the heels and feet, straining the plantar fascia and contributing to the development of a heel spur.
It's important to note that while heel spurs are often associated with these factors, not all individuals with these conditions will develop heel spurs. Genetics and individual variations can also play a role in the formation of heel spurs. If you experience persistent heel pain or discomfort, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
