Femoral shaft fracture reduction is a key technique for long bone fracture therapy.Based on the description of traditional reduction methods,the status,characteristics and performance of computer assisted reduction for femoral shaft fracture are summarized.Firstly,the technical aspects of navigated reduction in space mapping and visualization interface are analyzed.Secondly,the operational characters of serial mechanism robot and parallel mechanism robot in the procedure of bone fracture reduction are compared.The operation space and dexterity of serial robot are bigger,positioning accuracy and pose maintenance stability of parallel robot are higher.Then the real time operation feature of local operation and the anti-eradiation feature of tele-operation are investigated from the aspect of human-machine operation mode in the femoral shaft fracture reduction.Finally,the evaluation methods of fracture reduction effect and the development trend are discussed.
