现代假肢可以追溯到19世纪中期后各种物质被分配在尊重双方结合,阻止纤维的再现或骨胶着。最初,这些移植或自体组织,而不是物质(配件都构建)从远程或相邻位置,包括合并、肥胖,肌肉和皮肤。远,外科医生致力于各种人造的物质包括赛璐珞、玻璃、胶木移植或物质。Smith-Petersen 1940年工业化钴铬钼合金(cast cobalt-chromemolybdenumalloy)这是一个移植或髋关节的关节成形术,为关节提供改进的结果。

根据Allieu Y,Marck G,et al(1990)另外无数的外科医生开始越来越多的假体在各种物质代替单一的组合作为替代移植或关节成形术。金属假体被发现存在和更长更大的生物相容性。这包含髋关节假体的摩尔和汤普森,和膝关节假体(胫骨高原)MacIntosh和麦基弗。未替换结合外部,待疼痛的基础,特别对病人与关节炎的关节。根据Rolf O,Gohlke F(2004)要解决这个挫折,完成etalon-metal假肢的髋关节和膝关节的关节。早期的草图可能不提供正常的目的相结合,经历了从失事率升高引发了放松,过度磨损和感染。

Modern prosthesis goes back to the mid-nineteenth century after assorted substances were allocated amid respected combined sides to stop the reappearance of fibrous or bony ankylosis. Originally, there were autogenous tissue instead of these interpositional substances (fitting to the alike build) seized from remote or adjacent locations, encompassing combined, obese, muscle and skin. Far along, surgeons endeavored assorted substances which were man-made encompassing celluloid, glass, and Bakelite as interpositional substance. Smith-Petersen in 1940 industrialized the Vitallium (cast cobalt-chromemolybdenumalloy) which is an interpositional arthroplasty of the hip, which provided improved outcomes for arthritic joints.

According to Allieu Y, Marck G, et al (1990) to innumerable surgeons additionally commenced growing prostheses in assorted substances to substitute single side of the combined as a substitute to interpositional arthroplasty. Metal prostheses were discovered to have longer existence and larger bio-compatibility. This encompassed the hip prosthesis by Moore and Thompson, and knee prosthesis (tibial plateau) by MacIntosh and McKeever. The unreplaced combined external though, stayed a basis of pain, exceptionally for patients alongside arthritic joints. According to Rolf O, Gohlke F, (2004) to resolve this setback, finished etalon-metal prosthesis for the hip and knee joints were developed. The early sketches might not furnish the normal combined purpose, and endured from elevated wreck rate provoked by loosening, excessive wear and infection.
