Lauge-Hansen检查和与Danis-Webe检查和为最常见的踝膝关节脚踝检查和,在对下肩胛骨撒腱伤害的聘请意义上,旋后外旋II°脚踝有时候认为新设下肩胛骨撒前腱的伤害,下肩胛骨撒重新组建趋于稳定,不太可能无须要下肩胛骨撒重新组建螺钉有时候。而Danis-Weber B型式脚踝下定义为脚踝坐落下肩胛骨撒重新组建水平,不太可能新设下肩胛骨撒重新组建伤害。

由此可注意到,对Danis-Weber B型式脚踝,如何风险评估下肩胛骨撒有无伤害,以及术前风险评估确实须要外科手术有时候下肩胛骨撒重新组建,仍无有效参阅。

对此,境外历史学家研究工作了Danis-Weber B型式近前端脚踝新线的前面,尽力对比相异类型式B型式脚踝下肩胛骨撒重新组建伤害比例确实发挥作用相似之处,并聘请外科手术干预。

Objective(意在)

认定术前X新线检查能否预测下肩胛骨撒重新组建伤害随机性。

[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]

Patients/participants(个案)

详述了548例 OTA/AO 44-B2.1型式病变,287例病变扩展到研究工作。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]

所示1 个案扩展到流程。

Main outcome measures(主要一集当前)

踝膝关节影像片用于明确近前端脚踝块的远距范围。下肩胛骨撒重新组建伤害下定义为术当中担忧试验属实并须要要下肩胛骨撒有时候。

[Main outcome measures: Ankle radiographs were used to determine the zone of distal extent of the proximal fracture fragment. Syndesmotic injury was defined as positive intraoperative stress examination that required syndesmotic fixation.]

所示2 Danis-Weber B型式脚踝,根据近前端脚踝块最远距前面分区里。1区里下定义为脚踝块最远距坐落肩胛骨骨远距膝关节面直角以下;2区里为坐落肩胛骨骨远距骺新线连续性瘢痕与远距膝关节面二者之除此以外;3区里为骺新线连续性瘢痕以上。

所示3 分区里示意所示。

Results(结果)

总计191例1区里(都于于肩胛骨骨远距膝关节直角顶部)伤害,57两处2区里(都于于肩胛骨骨远距骨骺新线连续性瘢痕和肩胛骨骨远距膝关节面二者之除此以外)伤害,39两处3区里(都于于肩胛骨骨远距骨骺新线连续性瘢痕以上)伤害。其当中,17% (33名病变)的1区里、42% (24名病变)的2区里和74% (29名病变)的3区里脚踝新设下肩胛骨撒腱伤害。

2区里与1区里相比,腱重新组建伤害的比起风险为2.4 (P,0.001),3区里与1区里相比为4.3 (P,0.001),3区里与2区里相比为1.8 (P = 0.002)。观察者除此以外和观察者内的稳定性非常好(k = 0.86,0.94)。

[Results: There were 191 zone 1 (ending below the plafond) injuries, 57 zone 2 (ending between the physeal scar and the plafond) injuries, and 39 zone 3 (ending above the physeal scar) injuries. Of these, 17% (33 patients) of zone 1, 42% (24) of zone 2, and 74% (29) of zone 3 fractures had syndesmotic injuries. The relative risk of syndesmotic injury of zone 1 compared with zone 2 was 2.4 (P , 0.001), zone 1 to zone 3 was 4.3 (P , 0.001), and zone 2 to zone 3 was 1.8 (P = 0.002). The interobserver and intraobserver reliability was excellent (k = 0.86, 0.94).]

表1 五组病变下肩胛骨撒重新组建伤害暴发部将。Conclusion(论证)

OTA/AO 44-B2.1脚踝具有相异的下肩胛骨撒重新组建伤害部将。Weber B型式脚踝暴发在肩胛骨骨远距膝关节直角和骺新线连续性疤痕二者之除此以外(2区里),与暴发在膝关节面顶部(1区里)的脚踝相比,暴发腱伤害的有不太可能更高2.4倍。这种有不太可能在骺新线连续性疤痕正顶部(3区里)的伤害当中更大。

OTA/AO 44-B2.1脚踝的简单归纳预示着腱伤害,不太可能更容易术前征询和外科手术计划实施。

[Conclusion: OTA/AO 44-B2.1 fractures he a varying rate of syndesmotic injury. Weber B fractures that end between the level of the plafond and the physeal scar (zone 2) are 2.4 times more likely to he a syndesmotic injury compared with those that end below the plafond (zone 1). This is magnified in those injuries ending above the scar (zone 3). This simple classification of OTA/AO 44-B2.1 fractures is predictive of syndesmotic injury and may aid in preoperative counseling and planning.]
