Description
Technical field
The utility model belongs to orthopaedic medical treatment utensil technical field, is specifically related to a kind of baseThe ilium Wicresoft screw placement guider of printing in CAD 3D.
Background technology
Fracture of acetabulum is divided into Fracture Simple and the large class of compound fracture two, wherein, and simple boneFolding comprises 5 kinds of rear walls, rear pillar, antetheca, front pillar, transverse fracture, compound fracture bagDraw together rear pillar and rear wall, horizontal shape and rear wall, T shape, antetheca or the later half horizontal shape bone of front pillar companion5 kinds of folding, Both-column Fractures. Transverse fracture, twin columns in above-mentioned 10 kinds of fracture of acetabulumFracture, T-shaped fracture and front pillar accompany later half transverse fracture often to adopt front and back connection posterior approachThe fixing fracture that resets, but operation wound is large, in art, postoperative complications are many.
Sacral fracture is divided into following several types mostly: (1) separates with articulatio sacroiliacaRumpbone longitudinal fracture, general all with obvious displacement, treatment is comparatively complicated, except minority diseaseThe feasible open reduction of example and interior fixing outside, most of cases need to carry out traction reduction,Pelvis kicking strap suspension traction, gypsum pants are fixed, and the fracture end of separation sets backTime, can fix at the up pants gypsum of gypsum brandreth; (2) rumpbone epimere transverse fracture,Be more common in sacral 1～2 and sacral 3～4 places, if fracture line has a common boundary through sacrum 1～2Place, sacrum 1 and lumbar vertebrae shift forward simultaneously, are commonly referred to as " traumatic rumpbone slippage ",Due to displacement fracture and canalis sacralis narrow and can cause sacral nerve damage so that saddle area senseFeel obstacle and part gluteal paralysis; As sacrum 2～3 nerve damages, there is stool and urine meritDysfunction, this kind of case is often with transverse process of lumbar vertebra fracture, as waist 5 fractures of transverse process are saidBright ilio lumbar ligament fracture, other complication comprise retroperitoneal hematoma, rectal rupture, skinSkin is dampened necrosis and cerebrospinal fluid fistula etc., generally need to be according to displacement fracture situation and sacrum godImpaired and determine through whether, to occurring together injury of sacral nerve roots person, need row operative treatment more,To being shifted, obvious sacral fracture can consider to pass through percutaneous reduction by leverage; (3) the horizontal shape of rumpbone hypomereThe distal bone folded block of fracture shifts forward mostly, generally under local anaesthesia, refers to by anusThe method of inspection, pushes sclerite backward gently with forefinger and makes fracture end reduction, rightManipulative reduction loser, existing operation method is generally in open reduction and Kirschner wireLigamentopexis; (4) merge the transverse fracture of the sacrum of lumbosacral joint dislocation, waist 5 vertebral plates andThe little articular fracture of waist sacrum, waist more than 5 shifts forward, and transverse fracture of the sacrum is found in respectivelyIndividual sections, epimere transverse fracture, with both sides articulatio sacroiliaca ligament injury person, can causeRumpbone top is become flexible and is dumped forward; Sacrum 3～4 fracture as with obvious protruding one-tenth backward, be the damage of utmost point unstability, the means of prior art are pedicle screws fixations when at the angle+ fixation with steel wire ligation; (5) pure lumbosacral joint dislocation, except de-between waist sacralOutside position (waist 5 centrum reaches), most articular process and pedicle of vertebral arch bone with the 5th lumbar vertebraeFolding; The interverbebral disc of waist 5～sacrum 1 vertebra joint is also torn simultaneously, mostly selects way of escape vertebral archFix+vertebra of root screw internode Cage internal fixation; (6) bilateral of merging sacral fractureSacroiliac dislocation, many with the different sacral fracture of degree, even can there is pelvic ringFracture, rumpbone monoblock is shifted to front lower place. Visible bilateral ilium on normotopia X-ray filmRaise and waist sacral is shifted downwards; To smudgy judgement person, the CT of being difficult to of x-ray plain filmInspection can clearly show direction and the degree that rumpbone shifts forward.
Above-mentioned operation method is attended by serious postoperative complication more. Above-mentioned in order to overcomeShortcoming, clinically often through anterior lateral cervical approach, adopts Anterior column plate to add the fixing of rear pillar screwMode. Because the cross section of os metastyloideum is triangle, there are three faces, medial surface is fourRear wall and ischial tuberosity that Bian Ti, trailing flank are mortar, the lateral surface that anterolateral surface is mortar,Very abundant, the interior reliable support that fixedly provides is provided. Fracture of ilium need be from three directionsBe fixed and could form a firm fixed structure, these three directions are respectively iliumsTwo static lines of bone outward flange also need posterior superior iliac spine to be connected with anterior inferior spine simultaneously.Ilium uneven thickness and thinner, direction is slightly offset will locate inaccurately, causes tightHeavy postoperative complication.
The technological means addressing the above problem in prior art is to depend on facing of doctorBed experience maintains the orientation of whole surgical procedure light plate and screw, doctor according toHuman body ilium shape and thickness distribution, determine the angle and direction of pedicle screw, according to facingBed experience is carried out screw placement, particularly carries out " triangle " mechanics knot at sacral fractureWhen structure is fixing, screw is from the direction of posterior superior iliac spine and anterior inferior spine summit connecting lineImplant, but due to individual ilium configurations, tend to occur the side of screw placementTo departing from, because the ilium average thickness of human body is at 1cm left and right, the screw orientation of implantationOn deviation slightly, can cause screw tip end unsettled, cause screw loosening, interior fixingFailure, can not play fixing effect, also may damage important blood vessels and abdominal viscera,Often to take out screw and again implant, and due to ilium uneven thickness and entirety thinner,Ask once-through operation success as far as possible in operation, still occur implantation side if repeatedly put nailTo deviation, operation almost can be judged to be failure. Therefore the accurate location of screw is very heavyWant, whether successfully directly concern operation.
Also the technology that has doctor to adopt X-ray to guide in prior art, still, due to artFront mark location is complicated, exposed the effects limit such as too much it is extensive for doctor and patient x-rayApplication.
