clubfoot
Let an agent explain clubfoot, relay types, causes, prenatal detection and the Ponseti method from orthopaedic and global health sources, describe the named forms and flag the loosely filed alias, and distinguish clubfoot from positional talipes, metatarsus adductus, vertical talus and flat feet, without individual medical advice.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain clubfoot, relay types, causes, prenatal detection and the Ponseti method from orthopaedic and global health sources, describe the named forms and flag the loosely filed alias, and distinguish clubfoot from positional talipes, metatarsus adductus, vertical talus and flat feet, without individual medical advice.
A congenital deformity in which one or both feet are turned inward and downward, most commonly talipes equinovarus, present in roughly 1 in 1,000 births and more often in boys, usually idiopathic but sometimes associated with neuromuscular or genetic conditions, including familial forms the registry aliases name such as clubfoot due to PITX1 mutation, 5q31 microdeletion or 17q23 microduplication and bilateral forms; talipes calcaneus, where the foot is turned upward, is a different positional deformity that appears loosely filed. The Ponseti method of gentle serial casting, tendon release and bracing, developed by Ignacio Ponseti, is the standard treatment worldwide and is highly effective when started early, and families should be referred to trained clinicians.
What it is for: Not applicable; a birth condition.
It can be explain types and causes; relay the Ponseti method; describe named forms; relay global access programmes.
Distinguishing features
Present at birth
Rigid deformity
Casting-based treatment
Good outcomes with early care
What it looks like
A foot turned inward and downward with a deep crease, sometimes smaller than the other foot.
Physical character
incidence: about 1 in 1,000 births note - varies by population
Ponseti method: developed 1940s-1950s note - University of Iowa
bracing: typically until about 4-5 years at night note - per protocols
How it is recognised
Congenital inward and downward foot deformity
Talipes calcaneus, bilateral talipes equinovarus, familial clubfoot due to 17q23 microduplication, familial clubfoot with lower limb anomalies, familial clubfoot due to 5q31 microdeletion, familial clubfoot due to PITX1 mutation
Positional talipes corrects easily; metatarsus adductus bends the forefoot; vertical talus is rigid flatfoot; flat feet lack an arch
