Lead bicyclic dentoid process of axis's sighting device of hollow screw positioning.
Background technology
Fracture of odontoid process of vertebra dentata is the common fracture of cervical vertebra, accounts for the 10%~14% of fracture of cervical spine.Untreated or treatment are not
Odontoid fracture disunion rate is 42-72% caused by, and exists simultaneously potential atlanto-axial instability and determines, may cause brain stem,
The acute or chronic damage of spinal cord or nerve root, causes serious quadriplegia, respiratory dysfunction or even death.Therefore to pivot
The patient of vertebra odontoid fracture answers active treatment.From 1981, report used the direct treatment of internal fixation of odontoid fracture of screw for the first time
Since, it has proven convenient that compared with traditional therapy, this technology can not only rebuild the stability of articulatio atlantoepistrophica for clinical practice,
The activity of articulatio atlantoepistrophica can also be retained to the maximum extent, operation wound is small, and union rate is high, and is obviously improved minimal invasive treatment
Quality, it is believed that the technology is the first choice of odontoid fracture operative treatment.Although anterior screw treatment of internal fixation of odontoid fracture
Curative effect is clinically affirmed, but in the past due to mainly operating by rule of thumb, being oriented to Kirschner wire needs to adjust repeatedly, performs the operation
Randomness is big, in some instances it may even be possible to serious complication is generated, including screw extraction, displacement fracture, nonunion or screw tapping
Cdontoid process and injure spinal cord etc..Chinese patent 2012102768399 discloses one kind《Dentoid process of axis's screw sighting device》, adopt
Two shrinking connecting-rods being mounted on hollow guiding pipe are adjusted so as to change the direction of hollow guiding pipe, two shrinking connecting-rods with nut
It is connected on vernier control plate, vernier control plate is connect by ball-joint with supporting rod.This dentoid process of axis's screw sighting device
It can be used for guiding Kirschner wire in fracture of odontoid process of vertebra dentata treatment to be accurately positioned, so as to improve surgical quality, reduce surgical error,
Reduce the pain of patient.But in surgical procedure, since the position for needing to adjust is numerous, and adjusts each point of adjustment and mutually close
Connection, generally requires to adjust repeatedly and can be only achieved requirement, influences operation progress.In addition, the length for the shrinking connecting-rod that nut is adjusted is difficult
Precisely to measure, the position that shrinking connecting-rod is connected on vernier control plate is not known yet, this dentoid process of axis's screw sighting device
Coordinate data record position cannot be used, the positioning in can not performing the operation before repetition.
