Objective To compare the therapeutic efficacy of a self-locking zero-notch interbody fusion device for long-segment cervical spondylosis in elderly patients with traditional titanium plate combined with interbody fusion device.Methods From Jan 2019 to Jan 2021,elderly patients(>60 years)with 3-4 segments(C3-C7)radiculopathy,myelopathy,or mixed-type cervical spondylosis underwent anterior cervical discectomy and fusion(ACDF)using a zero-notch interbody fusion device(Group A,n=24)and ACDF using a titanium plate combined with an interbody fusion device(Group B,n=18).We recorded the surgery duration,blood loss,incision length and hospital stay,measure preoperative and postoperative intervertebral height,functional segment height and cervical lordosis,and also observe treatment outcomes and postoperative complications between the two groups.Results There were no statistically significant differences between the two groups in terms of gender,age,Japanese Orthopaedic Association(JOA)score,visual analogue scale(VAS)of upper limb,Neck Disability Index(NDI),preoperative intervertebral height,functional segment height and cervical lordosis.Blood loss,surgery time and hospital stay were similar in both groups,but Group A had shorter incision length(P<0.01)compared with Group B.There were no significant differences between the two groups in JOA scores,upper limb VAS and postoperative NDI,and even in postoperative intervertebral height,functional segment height and cervical lordosis recovery.Conclusion The zero-notch interbody fusion device is effective for treating long-segment cervical spondylosis.Compared with the traditional titanium plate combined with an interbody fusion device,it can avoid postoperative dysphagia with smaller incision and shorter surgery time,which makes it more suitable for elderly patients.
