Which one of the following disorders is associated with congenital talipes equinovarus ?

Congenital talipes equinovarus, also known as clubfoot, is associated with several disorders. These include:

1. Spina Bifida: This is a birth defect where there is incomplete closing of the backbone and membranes around the spinal cord.

2. Arthrogryposis: This is a condition of multiple joint contractures and can result in muscle weakness and fibrosis.

3. Edwards Syndrome (Trisomy 18): This is a genetic disorder caused by the presence of all or part of an extra 18th chromosome.

4. Myelomeningocele: This is a severe form of spina bifida in which the spinal cord and meninges protrude from a spinal opening.

5. Distal arthrogryposis: This is a condition that involves contractures of the hands and feet.

6. Other genetic syndromes: Some genetic syndromes may also be associated with clubfoot, but the relationship is less clear.

It's important to note that while these conditions are associated with clubfoot, not everyone with these conditions will have clubfoot, and not everyone with clubfoot will have these conditions.
