Which triad constitutes the classic clinical presentation of Klippel-Feil syndrome?

• A Webbed neck, shield chest, and widely spaced nipples
• B High arched palate, micrognathia, and glossoptosis
• C Low posterior hairline, short neck, and limited cervical motion ✓
• D Short stature, cubitus valgus, and delayed puberty

Explanation

Klippel-Feil syndrome is congenital fusion of cervical vertebrae, and the classic triad is a low posterior hairline, a short webbed neck, and restricted cervical motion, though all three appear together in only about half of patients. Option B describes Pierre Robin sequence, option A describes Turner syndrome, and option D also describes Turner syndrome. Associated anomalies include Sprengel deformity, scoliosis, renal and cardiac defects, so screening imaging is required.
