The damp type dentoid process of axis sighting device of 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
The odontoid fracture disunion rate caused by is 42-72%, and it is fixed to exist simultaneously potential atlanto-axial instability, may cause brain stem,
The acute or chronic damage of spinal cord or nerve root causes serious quadriplegia, respiratory dysfunction, or even dead.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 is oriented to Kirschner wire due to mainly operating by rule of thumb in the past and is needed to adjust repeatedly, and performed the operation
Randomness is big, in some instances it may even be possible to generate serious complication, 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 on hollow guiding pipe are mounted on to change the direction of hollow guiding pipe, two shrinking connecting-rods with nut adjustment
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, to improve surgical quality, reduce surgical error,
Reduce the pain of patient.But it in the course of surgery, since the position for needing to adjust is numerous, and adjusts each point of adjustment and mutually closes
Connection, generally requires to adjust repeatedly and can be only achieved requirement, influences operation progress.In addition, the length of the shrinking connecting-rod of nut adjustment 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.
