Plantar fasciitis
heel disorder
Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue that supports the arch of the foot. It results in pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest. Pain is also frequently brought on by bending the foot and toes up towards the shin. The pain typically comes on gradually. It affects both feet in about one-third of cases.
The cause of plantar fasciitis is not clear. Risk factors include overuse, such as from long periods of standing, an increase in exercise, and obesity. It is associated with inward rolling of the foot, a tight calf muscle and Achilles tendon, and a sedentary lifestyle. Heel spurs may play a role; they are commonly present in people who have the condition. Plantar fasciitis is a disorder of the insertion site of the ligament on the bone characterized by micro tears, collagen breakdown, and scarring.
Begin with the source’s own compact description: “Plantar fasciitis” is heel disorder. The dossier treats that line as a proposition to test through Plantar, fasciitis and heel, not as a finished interpretation.
Why this record matters
The phrase “heel disorder” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q52851. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
