Lauge-Hansen的测试与Danis-Webe的测试为最类似于的踝关节右腿的测试,在对下小腿里斯手肘损害的聘请意义上,旋后外旋II°右腿通常认为分拆下小腿里斯前手肘的损害,下小腿里斯为首长期性,可能无须要下小腿里斯为首螺钉分开。而Danis-Weber BHG右腿备注述为右腿坐落下小腿里斯为首低水平,可能分拆下小腿里斯为首损害。

由此可发现,对Danis-Weber BHG右腿,如何分析下小腿里斯有无损害,以及术前分析是否是须要开刀分开下小腿里斯为首,仍无有效参考。

对此,国外史家研究了Danis-Weber BHG腰椎右腿直通的前面,以求对比各有不同类HGBHG右腿下小腿里斯为首损害比由此可知是否是存在差异,并聘请开刀打压。

Objective(目的)

确认术前X直通检查能否预测下小腿里斯为首损害几率。

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

Patients/participants(病由此可知)

彻底改变了548由此可知 OTA/AO 44-B2.1HG病患者,287由此可知病患者划入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]

图1 病由此可知划入流程。

Main outcome measures(主要结局高效率)

踝关节影像片用于明确腰椎右腿块的启动时范围。下小腿里斯为首损害备注述为术里压力试验断定并须要要下小腿里斯分开。

[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.]

图2 Danis-Weber BHG右腿,根据腰椎右腿块最启动时前面分四区。1四区备注述为右腿块最启动时坐落小腿骨启动时关节面平面以下;2四比邻坐落小腿骨启动时骺直通闭合瘢痕与启动时关节面之数间;3四比邻骺直通闭合瘢痕以上。

图3 分四区示意图。

Results(结果)

共有191由此可知1四区(迄于小腿骨启动时关节平面顶部)损害,57所在前面2四区(迄于小腿骨启动时骨骺直通闭合瘢痕和小腿骨启动时关节面之数间)损害,39所在前面3四区(迄于小腿骨启动时骨骺直通闭合瘢痕以上)损害。其里,17% (33名病患者)的1四区、42% (24名病患者)的2四区和74% (29名病患者)的3四区右腿分拆下小腿里斯手肘损害。

2四区与1四区相较,手肘为首损害的相对高风险为2.4 (P,0.001),3四区与1四区相较为4.3 (P,0.001),3四区与2四区相较为1.8 (P = 0.002)。观察者数间和观察者内的可靠性非常好(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).]

备注1 三组病患者下小腿里斯为首损害暴发率。Conclusion(结论)

OTA/AO 44-B2.1右腿兼具各有不同的下小腿里斯为首损害率。Weber BHG右腿暴发在小腿骨启动时关节平面和骺直通闭合脸部之数间(2四区),与暴发在关节面顶部(1四区)的右腿相较,暴发手肘损害的某种程度高2.4倍。这种某种程度在骺直通闭合脸部上方(3四区)的损害里大得多。

OTA/AO 44-B2.1右腿的简单分类暗示着着手肘损害,可能有助于术前咨询和开刀计划实施。

[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.]
