Abstract:
Objective:To evaluate the efficacy of percutaneous vertebroplasty (PVP) by percutaneous bi-level bilateral puncture in the treatment of type ⅡA acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) with dense bone bands.Methods:From March 2017 to March 2018, 65 patients (65 vertebrae) with type ⅡA ASOTLF with dense bone bands were treated at Department of Orthopaedic Trauma, Qingdao Central Hospital. They were 25 males and 40 females, with an age of (71.6±8.4) years. The time from injury to operation was (3.5±0.7) d. They were divided into 2 groups according to different treatments. In the observation group of 31 cases (31 vertebrae), PVP was conducted by percutaneous bi-level bilateral puncture; in the control group of 34 cases (34 vertebrae), PVP was conducted by percutaneous single-level bilateral puncture. The 2 groups were compared in terms of operation time, volume of polymethyl methacrylate injected, incidence of bone cement leakage, incidence of vertebral refracture, diffusive distribution of bone cement in the vertebral body, and visual analogue scale (VAS) and Oswestry dysfunction index (ODI) at postoperative 1 day and 6 months.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). Operations were completed uneventfully in all the 65 patients. All the 65 patients were followed up for (8.2±1.2) months. There was no significant difference between the 2 groups in operation time, incidence of bone cement leakage or incidence of vertebral refracture for each vertebral body injured ( P>0.05). The volume of polymethyl methacrylate injected [(6.64±0.93) mL] and the excellent and good rate of diffusive distribution of bone cement in the vertebral body [87.1% (27/31)] in the observation group were significantly larger than those in the control group [(4.36±0.79) mL and 64.7% (22/34)] ( P<0.05). The VAS scores at postoperative 1 day and 6 months [2 (1, 2) and 1 (1, 2)] and ODIs at postoperative 1 day and 6 months (23.7%±1.6% and 18.8%±1.4%) in the observation group were significantly lower than those in the control group [2 (2, 3) and 2 (2, 2); 26.9%±4.2% and 22.1%±3.3%] ( P<0.05). The VAS scores and ODIs at postoperative 1 day and 6 months in all patients were significantly lower than those before operation ( P<0.05). Compression symptoms of the spinal cord and nerve root were observed in none of the patients. Conclusion:In the treatment of type ⅡA ASOTLF with dense bone bands, PVP by percutaneous bi-level bilateral puncture is more effective than the traditional PVP by percutaneous single-level bilateral puncture, and will not increase bone cement leakage or vertebral refracture.
