Long bone fracture, especially Long bone shaft fracture at lower limbs, adopt closed reduction intramedullary pin osteopathy usually.The good reset reaching fracture in art is one of necessary requirement of successful surgery enforcement.Malreduction can cause the limbs line of force abnormal, malunion of fracture, the serious consequences such as secondary revision procedure.Relative to open reduction fracture operation, closed reduction bone fracture bonesetting art can retain the blood supply of fracture end periosteum to greatest extent, promotes union of fracture.In addition, for comminuted fracture, open surgery might not reach anatomical reduction object, and the anti-destruction that will speed up the supply of fracture local blood, causes fracture delayed union even not connect, thus lose Surgical Significance.Therefore, especially aobvious important to the judgement of closed reduction situation of fracturing in Rhizoma Atractylodis Macrocephalae.Can touch the shaft fracture of bone mark for body surface, as fracture of tibia, distal fibular fracture etc., can judge the reset case of fracturing substantially by the seriality touching bone ridge.Abundant Fracture of femur is covered for muscle, the judgement of the reduction of the fracture situation during closed reduction, cannot be completed by the seriality touching bone ridge.Fracture of femur Coronal and sagittal plain fracture reduction can be assessed to line situation from two dimensional surface by normotopia in art and position, side X-ray examination, but this constructs as 3 D stereo due to skeleton, so when performing the operation for third dimension plane---transverse section, namely the Turning matched situation of shaft fracture is difficult to complete by common perspective assess relatively accurately.
The femoral rotation para-position appraisal procedure adopted in domestic and international art at present generally includes two large classes.One class is: by the method for surgical doctor visual assessment, comprise the mode combining perspective gained image, as cardinal principle ocular estimate, local dermatoglyph traveling observational method, electric knife leads method, lesser trochanter of femur consistency profiles, cortical bone balanced method, Tornetta biplane perspective estimation algorithm etc.Simple visual observations method (substantially ocular estimate and local dermatoglyph traveling observational method) precision cannot ensure substantially, and the Turning matched situation still existing defects of third dimension plane is estimated by the two dimensional image (electric knife leads method, lesser trochanter of femur consistency profiles, cortical bone balanced method, Tornetta biplane perspective estimation algorithm etc.) of x-ray, even occur that clinical operation is slipped up.
Another kind of: to simulate skeleton Space Rotating alignment situation in vitro by instrument, as 3D-CT real-time in art, the methods such as computer navigation.Because these class methods rely on relevant software programs, can accomplish to be close to accurate calculating and assessment, so the effect controlling to rotate is fairly good.These class methods often need special armarium and software kit, need the paraprofessional personnel team of a tacit cooperation simultaneously.Facts have proved, use said method to extend operating time, the probability of intraoperative blood loss and generation infection may be increased; Increase the perspective x-ray time simultaneously, may potential damage be caused.In addition, associated medical devices and software kit price high, basic hospital is probably difficult to popularize; Overall process also be unable to do without the good fit of paraprofessional personnel.
