Lauge-Hansen分型与Danis-Webe分型为最常见的踝关节小腿分型,在对下肩胛骨约翰膝盖损坏的指导意义上,旋后外旋II°小腿通常认为合并下肩胛骨约翰前膝盖的损坏,下肩胛骨约翰协同有所改善,显然无须下肩胛骨约翰协同皮带固定。而Danis-Weber B型小腿度量为小腿坐落于下肩胛骨约翰协同高水平,显然合并下肩胛骨约翰协同损坏。

由此可发现,对Danis-Weber B型小腿,如何评核下肩胛骨约翰有无损坏,以及术前评核究竟需手术固定下肩胛骨约翰协同,仍无适当参考。

举动,国外学者学术研究了Danis-Weber B型近末端小腿支线的右边,以求对比有所不同种类B型小腿下肩胛骨约翰协同损坏人口比可有究竟存在差异,并指导手术干预。

Objective(用以)

确定术前X支线检查能否预测下肩胛骨约翰协同损坏几部将。

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

Patients/participants(确诊)

回顾了548可有 OTA/AO 44-B2.1型病人,287可有病人纳入学术研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]

图1 确诊纳入流程。

Main outcome measures(主要结局指标)

踝关节影像片用以明确近末端小腿块的可执行范围。下肩胛骨约翰协同损坏度量为术中压力试验证实并需要下肩胛骨约翰固定。

[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 B型小腿,根据近末端小腿块最可执行右边分一区。1一区度量为小腿块最可执行坐落于肩胛骨骨可执行关节面矩形以下;2一邻接坐落于肩胛骨骨可执行骺支线连续性瘢痕与可执行关节面之有数;3一邻接骺支线连续性瘢痕以上。

图3 分一区示意图。

Results(结果)

共有191可有1一区(月终于肩胛骨骨可执行关节矩形下方)损坏,57处2一区(月终于肩胛骨骨可执行骨骺支线连续性瘢痕和肩胛骨骨可执行关节面之有数)损坏,39处3一区(月终于肩胛骨骨可执行骨骺支线连续性瘢痕以上)损坏。其中,17% (33名病人)的1一区、42% (24名病人)的2一区和74% (29名病人)的3一区小腿合并下肩胛骨约翰膝盖损坏。

2一区与1一区来得,膝盖协同损坏的相对风险为2.4 (P,0.001),3一区与1一区来得为4.3 (P,0.001),3一区与2一区来得为1.8 (P = 0.002)。观察者有数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).]

表1 两组病人下肩胛骨约翰协同损坏暴发部将。Conclusion(结论)

OTA/AO 44-B2.1小腿不具备有所不同的下肩胛骨约翰协同损坏部将。Weber B型小腿暴发在肩胛骨骨可执行关节矩形和骺支线连续性脸颊之有数(2一区),与暴发在关节面下方(1一区)的小腿来得,暴发膝盖损坏的显然性高2.4倍。这种显然性在骺支线连续性脸颊上方(3一区)的损坏中更大。

OTA/AO 44-B2.1小腿的简单界定预示着膝盖损坏,显然有助于术前建议和手术蓝图拟定。

[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.]
