This is a senile disease, with a higher proportion in the age group of 50 to 60 years, and the incidence rate tends to increase with age. The majority of patients were male, with a male to female ratio of 2: 1. The ossification of the ligamentum flavum is common in the middle and lower cervical vertebrae, with necks 5 to 6 being the most, followed by the necks 4 to 5 and the necks 6 to 7. The lesions range from 1 to 2 vertebrae. Rare. In the same segment, the incidence of bilateral and unilateral lesions is similar. Unilateral lesions are more common on the left.
