CT三维重建辅助手法复位加医用高分子夹板弹力带外固定治疗Colles骨折临床研究

Clinical Study on the Treatment of Colles Fracture with CT Three-Dimensional Imaging Assisted Manual Reduction and Medical Polymer Splint Elastic Band External Fixation

摘要: 目的：分析研究CT三维成像辅助手法复位加医用高分子夹板弹力带外固定治疗桡骨远端骨折的临床疗效。方法：选取在2020年1月至2021年12月期间骨伤科诊治的桡骨远端骨折120例，按随机数字表法将其分为CT三维成像组和对照组，各60例。CT三维成像组运用CT三维成像技术还原桡骨远端骨折全景图，通过观察CT三维成像桡骨远端骨折的全景图，进行手法复位并予医用高分子夹板弹力带外固定的方法进行治疗；而对照组直接采用手法整复小夹板外固定的方法进行治疗。研究分析治疗后两组患者桡骨远端骨折的临床疗效。结果：CT三维成像组在骨折复位后早期患肢的疼痛、肿胀较对照组明显减轻，差异具有统计学意义(P < 0.05)；患肢最终功能恢复及远期临床疗效优于对照组，差异具有统计学意义(P < 0.05)；在腕关节功能Cooney评分中优于对照组，差异具有统计学意义(P < 0.05)；同时在纠正骨折掌倾角、尺偏角、防止桡骨短缩上均优于对照组，差异具有统计学意义(P < 0.05)。结论：CT三维成像辅助手法复位加医用高分子夹板弹力带外固定治疗桡骨远端骨折临床研究结果显示，治疗组临床疗效明显优于对照组，骨折愈合率高，并发症与后遗症显著减少，综合疗效好，简便易行，值得临床推广应用。

Abstract: Objective: To analyze the clinical efficacy of CT three-dimensional imaging assisted manual reduc-tion combined with medical polymer splint elastic band external fixation in the treatment of Colles fractures. Methods: A total of 120 cases of Colles fractures diagnosed and treated in orthopedics department from January 2020 to December 2021 were selected and divided into CT three-dimensional imaging group and control group according to the random number table method, with 60 cases in each group. The CT three-dimensional imaging group used the CT three-dimensional imaging technology to restore the panoramic view of the Colles fracture. By ob-serving the panoramic view of the CT three-dimensional imaging of the Colles fracture, manual re-duction and external fixation with medical polymer splint were performed. However, the control group was treated with manual rectification and external fixation of small splint to analyze the clin-ical efficacy of Colles fracture in two groups after treatment. Results: The pain and swelling of the affected limb in the three dimensional CT imaging group were significantly reduced compared with the control group (P < 0.05). The final functional recovery and long-term clinical efficacy of the af-fected limb were better than those of the control group, and the difference was statistically signifi-cant (P < 0.05). The Cooney score of wrist function was better than that of control group, and the difference was statistically significant (P < 0.05). At the same time, it was better than the control group in correcting palmar angle, ulnar angle and preventing radius shortening, and the differences were statistically significant (P < 0.05). Conclusions: The clinical results of CT three-dimensional imaging assisted manual reduction combined with medical polymer splint elastic band external fixation in the treatment of Colles fractures show that the clinical efficacy of the treatment group is significantly better than that of the control group, the fracture healing rate is higher, the complica-tions and sequelae are significantly reduced, the comprehensive effect is good, simple and feasible, and it is worthy of clinical application.
