经舟骨月骨周围腕脱位的损伤机理与X线类型(附35例分析)

Traumatic Mechanism and Radiological Type of Perilunare Dislocation Periscaphoid (A Report of 35 Cases)

目的 :通过分析经舟骨月骨周围腕脱位的X线类型 ,探讨损伤机理与其内在的相关性。材料与方法 :回顾性复习有关文献和腕关节损伤资料 ,总结经舟骨、月骨周围腕脱位的规律 ,按类分型。结果 :经舟骨、月骨周围腕背侧脱位 16例 ,不典型的经舟骨、月骨周围腕背侧脱位 11例 ,经舟骨、月骨周腕背侧脱位伴桡骨茎突骨折 7例 ,经舟骨、月骨周围腕掌侧脱位 1例 ;其中各型的损伤机理与腕关节的自身解剖 ,韧带的生理强度和生物力学密切相关。结论 :经舟骨、月骨周围腕脱位的X线征象复杂 ,只有掌握损伤机理、诊断要点、准确分型 ,方能为临床治疗提供科学依据。

Purpose:To analyse the radiological type of perilunare dislocation periscaphoid and discussed its traumatic mechanism and inner correlativity.Materials and Methods:Review the literature and materials of wrist trauma respectively,and summerize the rules of perilunare dislocation periscaphoid to divided its types.Results:Perilunare dorsal disolcation periscaphoid 16 cases,untypical perilunare dorsal dislolcation periscaphoid 11 cases,perilunare dorsal disolcation periscaphoid with fracture of styloid and radius 7 cases,perilunare palmar dorsal dislocation periscaphoid 1 cases.Among them,its traumatic mechanism of every type varied with anatomy,physiological strenght,and biological energy.Conclusion:The radiological signs of perilunare dislocation periscaphoid is very complex,according to the traumatic mechanisms.Important points diagnosis and its types,provide more scientific bases for clinical therapy.
