文题释义:
桡骨远端单柱die-punch骨折:指轴向暴力传递导致仅局限在桡骨远端中间柱的塌陷或撕脱性骨折。仅波及中间柱的单柱die-punch骨折往往是桡腕关节处中立位和轴向暴力不大时发生。然而,桡骨远端单柱die-punch骨折在临床较为少见,多数情况下,更容易发生中间柱die-punch骨折合并轻度桡侧柱骨折,即双柱die-punch骨折临床上更为多见。
桡骨远端双柱die-punch骨折:指轴向暴力传递导致桡骨远端中间柱塌陷或撕脱性骨折为主,同时伴桡侧柱轻度骨折为辅的骨折。发生原因是轴向暴力较大或轴向暴力合并一定旋转暴力或者桡腕关节处尺偏位遭受轴向暴力所致。按照桡侧柱骨折波及部位的不同,分为干骺端型、关节面型和混合型3型。该分型较好地反映了桡骨远端双柱die-punch骨折发生力学机制和部位特点,符合AO骨折分型原则,具有较高一致性,对临床治疗和预后判断具有一定参考价值。

 
摘要
背景:按照三柱理论,有桡骨远端单柱和双柱die-punch骨折之分,文献已有单柱die-punch骨折分型报道,但尚无双柱die-punch骨折类型报道。
目的:探讨桡骨远端双柱die-punch骨折影像学特点和类型,以及新分型的价值。
方法:回顾性分析2007年6月至2017年6月498例桡骨远端双柱die-punch骨折影像学资料,根据影像学特点分为干骺端型、关节面型和混合型3型。选择2名影像学医师独立对100例桡骨远端双柱die-punch骨折行分型,分型结果采用Kappa方法行一致性分析。
结果与结论:①498例桡骨远端双柱die-punch骨折患者中,干骺端型130例,关节面型156例,混合型212例,未见无法归类者;②观察者间的Kappa系数为0.823-0.868,观察者内的Kappa系数为0.868-0.900,具有高度一致性;③按AO骨折分型,关节面型属于B型或C型,干骺端型和混合型均属于C型;④据此得出,该桡骨远端双柱die-punch骨折影像学分型较好地反映了骨折发生力学机制和骨折部位等特点,符合AO骨折分型原则,一致性好,对临床治疗和预后判断具有一定参考价值。

Abstract:

BACKGROUND: According to the three-column theory, there are single-column and double-column die-punch fractures of the distal radius. The single-column die-punch fracture has been reported, but there is a lack of study on double-column die-punch fracture.

OBJECTIVE: To explore the characteristics and imaging types of double-column die-punch fracture of the distal radius as well as the value of the new classification.
METHODS: A retrospective analysis of imaging data was made in 498 cases of double-column die-punch fracture of the distal radius between June 2007 and June 2017. According to the imaging characteristics of the fracture, the patients were divided into types of metaphysis, articular surface and mixed. Two radiologists were chosen and independently typed the fractures in 100 cases of double-column die-punch fracture of the distal radius, and agreement was analyzed with Kappa statistics.
RESULTS AND CONCLUSION: (1) In 498 cases of double-column die-punch fracture of the distal radius, type of metaphysis was found in 130 cases, type of articular surface in 156 cases and mixed type in 212 cases, and all were categorized. (2) The inter-observer Kappa coefficient was 0.823-0.868 and the intra-observer Kappa coefficient was 0.868-0.900, showing high consistency. (3) According to AO classification of fracture, the type of articular surface belonged to type B or type C, type of metaphysis and the mixed type belonged to type C. (4) These results suggest that the new imaging typing of double-column die-punch fracture of the distal radius well reflects the mechanical characteristics and fracture site, meets the principle of AO classification, has high consistency and provides reference for clinical treatment and prognosis judgment.
