三翼肋骨接骨板治疗多发性肋骨骨折及连枷胸的临床应用与力学分析

Clinical Application and Mechanical Analysis of the Treatment of Multiple Rib Fractures and Flail Chest Using Three-wings Rib Plate

该研究通过力学分析及临床验证,评价三翼肋骨接骨板治疗多发性肋骨骨折及连枷胸的临床疗效。建立肋骨与三翼接骨板模型,采用带预紧力的接触模拟进行有限元分析,结果发现三翼肋骨接骨板对骨折处内固定后,肋骨的可承受压力增大,固定效果良好。回顾复旦大学附属浦东医院53例使用三翼肋骨接骨板治疗肋骨骨折及连枷胸的临床资料,术后病人疼痛缓解,胸部CT三维重建均显示骨折复位良好,验证了三翼接骨板的临床疗效。三翼肋骨接骨板对肋骨骨折的治疗有较高的临床使用价值。

This research evaluated the clinical efficacy of three-wings rib plate in the treatment of multiple rib fractures and flail chest with mechanical analysis and clinical verification.The model of rib and threewings rib plate was reconstructed.The contact simulation with pretension stress was applied to the plate’s fixation,and it was found that the bearable stress of the rib fractures after fixation increased from the result which indicated a good fixation efficacy of the plate.Clinical data of 53 cases of rib fractures and flail chest treated with three-wings rib plate in Shanghai Pudong Hospital of Fudan University were retrospectively analyzed.After the operation,the pain of the patients was relieved.Postoperative CT reconstruction of the chest showed good restoration of the rib fractures,which verified the clinical efficacy of three-wings rib plate.The three-wings rib plate showed a high value in clinical use for treatment of rib fractures.
