Development and clinical application of lateral segmental positioning plates of the body surface spine
Objective To investigate the clinical efficacy of body-surface guide plates for lateral segmental positioning in the thoracolumbar spine.Methods From March 2018 to March 2021,768 gerontal patientss underwent percutaneous vertebro-plasty with balloon dilatation due to thoracolumbar compression fracturess,356 males and 412 females.aged from 64 to 92 years old with an average of(77.9±13.5)years old.All patients were treated in hospital within 1 week after injury.All patients underwent preoperative localization,and were divided into localization plate group and locator group according to different lo-calization methods.There were 390 patients in the localization plate group,180 males and 210 females,aged from 64 to 92 years old,with an average age of(78.4±14.3)years old.There were 378 patients in the locator group,176 males and 202 fe-males,aged from 64 to 90 years old,with an average age of(77.5±13.4)years old.After preliminary positioning with the above two methods,skin markers were made,cloth was routinely disinfected,and the spinal lateral position was fluoroscopically ex-amined after the fine needle was inserted into the marked point and the vertical body at the near tail end.The accuracy of the original positioning method was evaluated.The number of times,time and accuracy of positioning of the two groups of patients were compared and analyzed.Results The specific data of patient positioning in the two groups were collected for statistical analysis.The number of times of fluoroscopy in the positioning plate group and the locator group was(3.3±0.5)times and(5.0± 1.2)times,and the positioning time was(60.4±9.4)s and(105.0±30.9)s,respectively.The accuracy of fluoroscopy was 97.5％(380/390)and 85.7％(324/378),respectively,with statistical significance(P＜0.05).Conclusion The lateral seg-mental positioning plate of the body surface spine has the advantages of simple operation,accurate positioning,and reducing X-ray radiation for patients,which is worthy of clinical application.
