Plantar Fibroma (fibromatosis) occurs with an excessive accumulation of collagen fibres through the plantar fascia. This is a long band of tissue that lies in the bottom of your foot and connects the ball of your foot (the metatarsal heads) to the heel (the calcaneus bone).
How Does It Develop?
It is uncertain as to whether the plantar fibromas form due to an abnormal response in healing a microtear through the plantar fascia, or whether it is strictly a condition of abnormal collagen development. They are believed to be more likely to occur after trauma or injury to the plantar fascia, in patients with a predisposition to other connective tissue disorders. Plantar fibromas are more common in men than women. They are more likely to appear at in middle aged or elderly patients, although they can appear at all ages.
What To Look Out For?
Typically, the condition can be asymptomatic with no major concerns or symptoms.
A visible bulge in the central or medial plantar area of the foot.
There can be pain after long bouts of walking, standing – especially when the nodules begin to affect soft tissue under the foot.
Can be painful to touch due to their location; they are susceptible to experiencing pressure from footwear or the ground when weight-bearing.
How to manage your condition?
Plantar fibromas themselves are benign; i.e. non-cancerous and can present asymptomatic. In early stages observation is key to manage if it begins to progress
Conservative management is recommended in the early stages of the condition.
