a
Study reports additional surgery on four patients: preplanned anterior spinal fusion (n = 2), and anterior spinal fusion from numbness (n = 1) or C5 radiculopathy (n = 1); treatment group NR7; study reports reoperation (anterior cervical fusion) for two patients, but it is unclear which type of cervical laminoplasty these patients received.8
b
Study reports complications, including superficial wound infections or blood loss of > 500 mL, in 10 patients; details, including treatment group, NR.7
