Double-door staples, double-door spacers, and single-door miniplate can achieve favorable clinical outcomes for cervical spondylotic myelopathy. The blood loss of a double-door staple is less than that of a single-door miniplate, and the operation time of a double-door staple is shorter than that of a double-door spacer. The mean expansion ratio of cervical intraspinal cross-sectional area decreased in the order of double-door staple > double-door spacer > single-door mini plate. Overall, the double-door staple is a safe and innovative alternative choice for the treatment of CSM 1)
