摘　　要：目的 :测量舟骨骨折线夹角和X线形态 ,探讨舟骨形态在损伤时与桡骨远端尺倾关节面夹角的相关性 ,为临床提供可靠的影像学依据。方法 :对 10 0例舟骨骨折线与桡骨远端尺倾关节面所成的角度和两端长度及宽度进行测量分型。结果 :骨折夹角最大 70° ,最小 2 0° ,其中Ⅰ型 30～ 5 0°者 82例 ,Ⅱ型 5 0°以上 10例 ,Ⅲ型 30°以下 8例。舟骨X线形态 :细长型 82例 ,粗短型 11例 ,不规则型 7例。结论 :粗短型舟骨损伤后骨折夹角较大在 5 0～ 70°之间 ,多见于舟骨远端。细长型夹角在 30～ 5 0°之间 ,好发腰部。不规则型舟骨夹角在 30°以下 。Objective:To meansure the clip-angle and X-ray patterns of scaphoid fracture,to study the correlativity of scaphoid pattern and the clip-angle of distal joint-surface in trauma of wrist,so that to provide the imaging key for clinic.Methods:The clip-angle between the scaphoid fracture line and the joint face of the lower end of radius,the length of both end and width of scaphord were measared and clasified in 100 cases with scaphoid fractnre.Results:The greatest fracture clip-angle 70 degree and smalles one was 20 degree,among them Ⅰ type was in 82 cases(30～50 degree),Ⅱ type was in 10 cases(50 degree)and Ⅲ type was in 8 cases(30 degree).The X-ray pattern of scaphoid:thin and longer type were in 82 cases,thick and shorter type were in 11 cases and irregular type was in 7 cases.Conclusion:In the thick and shorter type,the fracture clip-angle is 50～70 degree,usually see in distal end of scaphoid.In the thin and longer type,the clip-angle is 30～50 degree,and usually see in waist.In the irregular type,the clip-angle is below 30 degree,usually see in proximal end and ofthe combine with reverse or multiple trauma of othen carpal bone.
