Single most likely diagnosis
- Congenital clubfoot (Talipes equinovarus): This condition is characterized by an over flexed foot, often due to abnormal development of the muscles, tendons, and bones in the foot. It is one of the most common congenital deformities.
Other Likely diagnoses
- Congenital vertical talus: A rare congenital deformity of the foot where the talus bone is abnormally positioned, leading to a rigid flatfoot or rocker-bottom foot deformity.
- Metatarsus adductus: A congenital deformity where the front part of the foot is turned inward, often associated with clubfoot.
Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Spina bifida or other neural tube defects: Although less common, these conditions can cause foot deformities due to nerve damage or muscle weakness.
- Arthrogryposis multiplex congenita: A rare condition characterized by multiple joint contractures, including the feet, which can be life-threatening if not properly managed.
Rare diagnoses
- Fibular hemimelia: A rare congenital absence or underdevelopment of the fibula bone, which can cause foot deformities.
- Tarsal coalition: An abnormal connection between two or more of the tarsal bones in the foot, which can cause rigid flatfoot or other foot deformities.
- Diastrophic dysplasia: A rare genetic disorder that affects bone and cartilage development, often causing severe foot deformities.
