摘要:

文题释义:
胫骨平台骨折:胫骨平台位于胫骨近端,外形膨大,松质骨较为丰富,密质骨较少,对暴力抵抗能力较差,其关节面与股骨远端关节面相对应。胫骨平台骨折近年来呈增多趋势,占全部骨折的1.2%,粉碎性骨折更多见,常合并严重的半月板、韧带和血管神经损伤,且常遗留术后畸形等。
骨折线三维模型:2009年ARMITAGE等提出了“骨折线分布地图”技术(骨折地图技术),该技术将骨折患者的原始CT资料行三维重建,将各重建模型拟合叠加到选择的标准模型上,对骨折线的走行分布、骨折形态特征进行直接观察,为各处骨折的诊断、分型、手术入路及方案、内固定物选择提供了一种更先进的统计研究方案。

背景:胫骨平台骨折常由于其复杂的骨折类型及不满意的治疗结果,手术入路及治疗方法常不明确。临床常用骨折分型各有侧重,给临床医生的选择带来一定困难。近年来随着骨折地图绘制技术应用于临床研究,骨折地图研究越来越多。
目的:重建胫骨平台骨折三维模型,分析骨折线特点。
方法:回顾性研究133例胫骨平台骨折患者的病历资料,收集其原始影像资料,在Mimics 17.0软件中重建骨折模型,在3-matic 9.0软件中将重建的骨折模型复位并拟合到标准模板,在标准模板上临摹并叠加全部骨折线,分析骨折线分布规律。
结果与结论:①胫骨平台骨折患者年龄大多分布于43-52岁(33.1%),其中男性患者骨折好发于43-52岁(35.4%),平均发病高峰为47岁;女性患者骨折好发于53-62岁(40.7%),平均发病高峰为52岁;②胫骨外侧平台骨折(81.8%)多于内侧平台(31.4%),骨折线主要集中在外侧平台内侧并延续至胫骨结节、Gerdy结节交界区(75.9%)和髁间嵴(71.5%),次要骨折线有3条,一条从髁间嵴向腓骨头前缘走行(21.2%),第2条沿前外侧平台外缘呈外弧形走行(13.8%),第3条从内侧平台前内侧向后外侧走行并延伸至外侧平台(15.3%);骨折线较少在胫骨结节(13.1%)、Gerdy结节(10.9%)、后内侧骨块(8.6%)、胫骨腓关节面(7.3%)出现;③结果表明,胫骨平台骨折有好发部位,临床中不能完全依赖某一骨折分型,需要个性化分析和治疗。

Abstract: BACKGROUND: Due to complex fracture types and unsatisfactory treatment results of tibial plateau fracture, the surgical approach and treatment methods are often unclear. The common clinical classification of tibial plateau fracture is different, which brings some difficulties to the choice of clinicians. In recent years, with more and more application of fracture mapping technology in clinical research, more and more studies on tibial plateau fracture mapping have been conducted.  
OBJECTIVE: To reconstruct the three-dimensional model of tibial plateau fracture and to analyze the characteristics of fracture lines.
METHODS: A retrospective study was conducted in 133 cases of tibial plateau fractures. The original imaging data of patients were collected and used to reconstruct fracture model in Mimics 17.0 software. The reconstructed fracture model was reduced and fitted to the standard template and all fracture lines were delineated and superimposed on the standard template in 3-matic 9.0 software.  
RESULTS AND CONCLUSION: (1) Most patients of tibial plateau fracture were aged between 43 and 52 years (33.1%). Fractures in male patients mainly occurred between 43 and 52 years old (35.4%), and the average peak age of onset was 47 years; fractures in female patients mainly occurred between 53 and 62 years (40.7%), and the average peak age of onset was 52 years old. (2) The fracture line of lateral tibial plateau (81.8%) was more than that of medial plateau (31.4%). Fracture lines tended to occur mainly on the inner part of the lateral condyle that extended to the junctional zone between Gerdy’s tubercle and the tibial tubercle (75.9%), as well as intercondylar eminence (71.5%). There were three secondary fracture lines: One ran from the intercondylar eminence to the front of the fibular head (21.2%). The second line took an outer arc along the outer edge of the anterolateral tibial plateau (13.8%). The third line ran from the anteromedial to the posterolateral that extended to lateral tibial plateau (15.3%). Fracture lines were less likely to occur in the tibial tubercle (13.1%), the Gerdy’s tubercle (10.9%), the posteromedial fragment (8.6%), and tibiofibular articular surface (7.3%). (3) Results have showed that tibial plateau fracture has its own predilection sites. In clinical work, individual analysis and treatment are needed instead of relying entirely on a certain fracture type.
