摘　　要：目的:为人工肩关节置换治疗肱骨近端粉碎性骨折、假体设计提供参考数值。方法:对68例成人干燥肱骨标本进行观测分析。结果:肱骨头横径:左侧(40.67±1.90)mm,右侧(40.49±1.36)mm;肱骨头纵径:左侧(44.54±1.31)mm,右侧(43.45±1.48)mm;肱骨头后倾角:左侧(26.59±1.36)°,右侧(26.85±1.61)°;头结节距(肱骨头最高点至大结节最高点的垂直距离):左侧(6.63±1.13)mm,右侧(6.80±1.02)mm;颈干角:左侧(134.320±3.49)°,右侧(135.58±1.50)°。结论:(1)假体头直径在(40～45)mm,后倾角30°左右,假体高度应该高于大肱骨结节6～8mm;(2)人工肩关节置换应该考虑选择适合的假体高度、后倾角度、假体头的大小等,这与患者肩关节功能重建、并发症的发生密切相关。Objoctive： To provide anatomic parameters for shoulder arthroplasty after comminuted proximal humerus fracture and the design of shoulder joint prosthesis. Methods： 68 Chinese adult cadaveric humeri were measured and assessed with SPSS 10.0 software. Results： Transverse diameters of left and right humeral heads were （40.67 ±1.90）mm and （40.49±1.36）mm, vertical diameter （44.54±1.31）mm and （43.45±1.48）mm, retroversion angle （26.59±1.36）° and （26.85±1.61）°, max interval of humeral humeral-tuberosity （6.63± 1.13 ）mm and （6.80±1.02）mm, humeral head-shaft angle （134.320±3.49）° and （135.58±1.50）° respectively. Conclusions： For ideal prosthesis, the diameter of the head of 40 -45mm, retroversion angle of 30° and the height above the greater tubercle about 6-8cm are a reliable selection. The height of prosthesis, retroversion angle and the size of the head have to be considered during arthroplasty, which concerning with the functional reconstruction of shoulder joint.
