Abstract:
Objective:To compare the efficacy between percutaneous vertebroplasty (PVP) with unilateral double-target puncture approach plus side opening propeller and traditional PVP in the treatment of Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 40 patients with Kümmell disease admitted to Zhengzhou Orthopedic Hospital from January 2020 to June 2022, including 11 males and 29 females; aged 61-95 years [(74.3±9.5)years]. Twenty patients received the PVP with unilateral double-target puncture approach plus side opening propeller (observation group), and 20 patients were treated with traditional PVP (control group). The operation time, volume of cement injection and distribution levels of bone cement were compared between the two groups, as well as the visual analogue score (VAS), Oswestry dysfunction index (ODI), Cobb angle, anterior height of the vertebral body before operation and at 1 day and 6 months after operation. The incidence of complications was also compared between the two groups.Results:All patients were followed up for 6-12 months [(9.1±2.8)months]. The operation time was (40.3±4.5)minutes in the observation group and (38.6±3.5)minutes in the control group ( P>0.05). The volume of cement injection was (6.5±1.3)ml in the observation group, significantly more than that in the control group [(5.4±1.0)ml] ( P<0.01). The distribution levels of bone cement in the observation group (0 patient in Grade 1, 3 in Grade 2, and 17 in Grade 3) were better than those in the control group (1 patient in Grade 1, 15 in Grade 2, and 4 in Grade 3) ( P<0.01). There were no significant differences in the VAS, ODI, Cobb angle or anterior height of the vertebral body between the two groups before operation (all P>0.05). One day after operation, the VAS in the observation group and control group was (1.6±0.7)points and (2.5±0.8)points, with the ODI of 16.1±3.3 and 21.3±4.1, Cobb angle of (18.4±2.9)° and (21.4±2.0)° and anterior height of the vertebral body of (23.7±1.8)mm and (20.1±1.7)mm. Six months after operation, the VAS in the observation group and control group was (1.3±0.5)points and (2.3±0.9)points, with the ODI of 15.0±3.8 and 20.8±3.9, Cobb angle of (19.3±2.9)° and (22.4±1.7)°, and anterior height of the vertebral body of (23.4±1.8)mm and (19.8±1.6)mm. The VAS, ODI, Cobb angle and anterior height of the vertebral body in the observation group were better than those in the control group at 1 day and 6 months after operation (all P<0.01). The VAS, ODI, Cobb angle and anterior height of the vertebral body were significantly improved in the two groups at 1 day and 6 months after operation compared with those before operation (all P<0.01), but there were no significant differences between 1 day and 6 months after operation (all P>0.05). The incidence of complications was not significantly different between the two groups ( P>0.05). Conclusion:The PVP with unilateral double-target puncture approach plus lateral opening propeller not only allows for adequate and evenly distributed injection of bone cement, but also effectively reduces the pain, improves the quality of life, corrects the kyphosis and restores the height of the vertebral body in treating Kümmell disease compared with the traditional PVP.
