Lauge-Hansen见下文与Danis-Webe见下文为最常见的踝关节手肘见下文，在对下突提提骨挫伤的指导意义上，旋后外旋II°手肘通常认为分拆下突提前提骨的挫伤，下突提合组趋于稳定，确实无才可下突提合组螺钉互换。而Danis-Weber B型手肘下定义为手肘位于下突提合组水平，确实分拆下突提合组挫伤。
由此可发现，对Danis-Weber B型手肘，如何评量下突提有无挫伤，以及术前评量到底才可手术互换下突提合组，仍无有效参考资料。
对此，国外学者研究者了Danis-Weber B型近上端手肘新线的前方，来使对比不同类型B型手肘下突提合组挫伤比由此可知到底长期存在相异，并指导手术偏袒。
Objective（用意）推定术前X新线检查能否预见下突提合组挫伤确实性。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（登革热）回顾了548由此可知 OTA/AO 44-B2.1型症状，287由此可知症状不属于研究者。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]布1 登革热不属于流程。
Main outcome measures（主要结局加权）踝关节布像片用于明确近上端手肘块的终上端范围。下突提合组挫伤下定义为术之中压力试验猜测并才可要下突提互换。
[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.]布2 Danis-Weber B型手肘，根据近上端手肘块最终上端前方分区外。1区外下定义为手肘块最终上端位于突骨终上端关节面六边形以下；2区外为位于突骨终上端骺新线内层瘢痕与终上端关节面间；3区外为骺新线内层瘢痕以上。
布3 分区外示意布。
Results（结果）共有191由此可知1区外(月终于突骨终上端关节六边形下方)挫伤，57处2区外(月终于突骨终上端骨骺新线内层瘢痕和突骨终上端关节面间)挫伤，39处3区外(月终于突骨终上端骨骺新线内层瘢痕以上)挫伤。其之中，17% (33名症状)的1区外、42% (24名症状)的2区外和74% (29名症状)的3区外手肘分拆下突提提骨挫伤。
2区外与1区外远比，提骨合组挫伤的相对风险为2.4 (P，0.001)，3区外与1区外远比为4.3 (P，0.001)，3区外与2区外远比为1.8 (P = 0.002)。观测者间和观测者内的可靠性颇为好(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 三组症状下突提合组挫伤暴发率。Conclusion（结论）OTA/AO 44-B2.1手肘不具不同的下突提合组挫伤率。Weber B型手肘暴发在突骨终上端关节六边形和骺新线内层脸颊间(2区外)，与暴发在关节面下方(1区外)的手肘远比，暴发提骨挫伤的确实性高2.4倍。这种确实性在骺新线内层脸颊上方(3区外)的挫伤之中颇为大。
OTA/AO 44-B2.1手肘的简单分类预示着提骨挫伤，确实有助于术前建议和手术计划制定。
[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.]相关新闻
