Background technology
At present, in artificial joint replacement, hip replacement surgery is widely used, when hip replacement, it is with respect to 40～45 ° of sagittal plane abductions that acetabular bone requires setting angle, leans forward 10～25 ° with respect to coronalplane, and this is a 3 D stereo angle, the grasp of this angle generally leans on patient's experience and position, range estimation to judge in art, often has certain error.For some acetabular dysplasia, entirely with patient's experience, operation does not make the acetabular component setting angle not reach the physiology angle probably under unfamiliar situation, through regular meeting the postoperative hip dislocation takes place, and causes operative failure when having normal anatomical relationship.It is vertical that some prosthese manufacturer adds a suspention on the reamer for hip arthroplasty,acetabulum connecting rod at present, can only solve the abduction angle, do not determine top rake, and application is restricted.
Need posterior cervical to beat pedicle nail fixedly during cervical vertebra disposing because of suffering from unstability Hangman fracture equally, it is variant because of disposing cervical vertebra position difference to advance to follow closely angle, when taking C
2.3During the neck fusion, getting C2 lateral mass mid point is entry point, being generally head-end tilts 20～30 °, tilt 25～35 ° to the midline, employing is tilted 35～40 ° to the midline for C3C4, upward soleplate is parallel with vertebral body, because cervical vertebra is in the human nerve concentrated position, it is improper as selecting to advance to follow closely angle, causes patient death or paralysis probably, at present except that relying on the doctors experience operation, also have and adopt location navigation device assist location, the location navigation device can accurately be measured into nail angle, but the price eighteenth of the twenty is expensive, want 300～5,000,000 yuan, limited its promotion and application for every.
