【摘要】 目的:设计与骨盆、髋臼的解剖形态与力学性能相适应的骸臼骨折内固定器,探讨髋臼骨折内固定一种新技术与新方法。 方法:1、取已知性别成套成人干燥骨盆标本109副,按髋骨盆面线弧特征,确定观测项目和测量标准,进行几何测算,主要有:(1)双侧弓状线弧长和弦长并算出弧度;(2)用几何法测算出经弓状线三等分中点的弧形骨面弧度—弓前弧、弓中弧、弓后弧 (3)耻骨梳的长度和弧度;(4)弓耻弧长度:由弓状线和耻骨梳的长度组成;(5)髋臼中心点到弓状线的距离即臼心弓距。对所得结果用SPSS软件处理。2、根据髋骨盆面的三维结构、标本测量相关数据以及髋臼骨折的生物力学,设计与髋骨盆面三维解剖结构相吻合的重建钢板。它由钢板体部、上翼板和下翼板共同构成;并做力学性能测试。3、按Letournel和Judet分类,对两组非后壁和后柱髋臼骨折病例均采取髂腹股沟入路,分别采用普通重建钢板和新设计内固定器固定,用SPSS软件统计分析两组的手术时间、失血量、复位满意率和优良率等。 结果:1、男女弓状线弧长为(57.71±5.59)mm、(52.08±6.27)mm,纵向弧度为61.41°±11.86°和67.42°±11.94°;男女弓状线横向弧度分别为弓前弧111.16°±12.37°和111.14°±21.09°、弓中弧106.81°±14.60°和109.58°±16.50°、弓后弧138.00°±更多还原

【Abstract】 Objective: To design a style of internal buttress plate for acetabular fractures ,which adapt to the structure and biomechanics of internal surface of acetabular wall; To introduce a new technique for treatment acetabular fracture with the new style of internal buttress plate.Methods: 1. The lengths of the arc of arcuate line of hipbone on 109 pairs (F58, M51) were measured. In addition, the distance between the center of the acetabulum and arcuate line and three vertical chords of the arcuate line between the points where each side 2 cm to the arcuate line at the middle of each one third arcuate line were also measured ,and the distance from the center of acetabulum to arcuate line is also measured. All the data and its radians were calculated by SPSS software. 2. To design the style of internal buttress plate according to the data by measuring and the biomechanics of acetabulum. 3. To compare the results of treatment for tow groups of acetabular fractures with common buttress plate and the new style buttress plate.Results: 1.The female and male average arc lengths(mm)are 57.71± 5.59 and 52.08±6.27,the radians(°) are 61.41±11.86 and 67.42±11.94 , transverse radians(°)of arcuate line are 111.16±12.37 and 111.14±21.09 in anterior third,106.81±14.60 and 109.58±16.50 in middle third, 138.00±16.60 and 144.46± 15.21 in posterior third. The female and male average arc lengths(mm) of arcuate line plus pecten pubis 123.50 ± 8.01 and 127.75 ± 7.82; distance from the更多还原
