Other first branchial cleft abnormalities, such as cleft lip/palate
What is cortical thumb, and what does it indicate?
Having thumb enclosed within the palm--can be normal and resolve by 7 months, or represent an UMN lesion
How can you differentiate cortical thumb that is a sign of UMN lesions, vs a benign, and solitary finding?
Look for other s/sx of UMN lesions such as muscle tone, tendon reflexes etc
What is the most common etiology of bowing of the legs?

May lead to compromised foot function, thus surgery is usually indicated.
What are flexible (pronated) flatfeet? Prognosis/treatment?
