Objective To explore the efficacy of cervical expansive open-door laminoplasty(CEOL)under ultrasound bone curette(UBC)in the treatment of multilevel cervical spondylotic myelopathy(MCSM).Methods A total of 90 MCSM patients who received CEOL treatment at the Second Hospital of Lanzhou University from September 2021 to No-vember 2022 were collected and divided into UBC group(48 cases)and conventional group(42 cases)according to whether UBC was used or not.Perioperative indexes,pain/function scores and imaging parameters were compared be-tween the two groups.Results The operation duration[(115.00±18.74)min vs.(130.12±23.38)min],intraopera-tive blood loss[(152.17±27.36)mLvs.(246.39±30.05)mL]and postoperative drainage volume[(120.35±21.17)mL vs.(211.06±42.58)mL]in UBC group were lower than those in conventional group(t=3.403,15.568,13.039,P＜0.001).With the passage of time after surgery,visual analogue score(VAS),cervical posterior extension range of motion(ROM)and cervical curvature all showed a decreasing trend(P＜0.05).Japanese Orthopaedic Association(JOA)score,sagittal vertical axis(SVA)and vertebrae-spinal cord posterior margin distance all showed an increasing trend(P＜0.05).Differences in the comparison of all scores and imaging parameters between the two groups and on the interaction between the groups and time were not statistically significant(P＞0.05).Conclusion UBC and CEOL assis-ted with bone rongeur can alleviate pain in MCSM patients,promote spinal cord to drift backward,restore nerve function,and have little effect on cervical motion.Compared with bone rongeur,UBC can significantly shorten the duration of oper-ation,reduce intraoperative blood loss and postoperative drainage flow,but CEOL has a certain impact on the cervical sagittal balance of patients,and clinical attention should be paid to it.
