Abstract
The invention discloses a lumbosacral portion and ilium combined device and a method for the combined fixation of lumbosacral portion and ilium. The lumbosacral portion and ilium connecting device comprises an iliac-screw connecting part and a bar connecting part, which are connected together through three connecting shafts and two connecting rods. The lumbosacral portion and ilium connecting device is mainly used for enhancing the internal fixation stability of the lumbosacral portion and pelvises; during the fixation process of iliac-screws, through the replacement of the screw inlet point position and screw channels and the reduction of the screw length, the risk that iliac-screws penetrate the bone to destroy important visceral organs, nerves and blood vessels in a pelvic cavity is remarkably reduced, and besides, the fixation strength can be enhanced, and particularly, the stress load between lumbar 5 and sacrum 1 is reduced; meanwhile, through the connection of the lumbosacral portion and ilium connecting device, the stripping range and the local trauma of surrounding tissues during the operation process are reduced, the lumbar vertebra and pelvis are enabled to be connected and fixed directly, complications of the fixation failure of the lumbosacral portion and the formation of pseudarthrosis are avoided, and especially for a patient who cannot be fixed by sacrum screws, the internal fixation strength of the lumbosacral portion and the pelvises can be remarkably improved.
Description
Technical field
The invention belongs to the supporting device of internal fixation of spine, be mainly used in increasing stability maintenance in lumbosacral section and pelvis, be specifically related to a kind of waist ilium joint control and adopt this waist ilium joint control to carry out waist ilium associating fixing means.
Background technology
The lumbosacral segment spinal fusion is a challenging zone in spinal surgery always.Local complicated anatomical structure, unique biomechanics characteristic and the relatively poor sclerotin quality of rumpbone are all the reasons that the lumbosacral segment spinal column is difficult to merge.Particularly long segment need to merge the patient to rumpbone, and sacrum 1 pedicle screw need to bear great physiological loads, therefore often causes the severe complications such as lumbosacral joint place's screw loosening and pseudoarticulation formation.
Development along with spinal surgery, fixing concept and the technology of spinal column-pelvis accepted more and more widely and used, namely insert by posterior lumbar, rumpbone and ilium nail and carry out fixedly fusion of waist sacrum ilium, obtained satisfied stable fixed effect, particularly for fixing the fusion and the protruding case such as orthopedic of spinal column long segment side after the slippage of vertebral body severe, by insert ilium follow closely carry out waist sacrum-pelvis fixedly fusion can obtain higher fusion rate.
But in the clinical practice of ilium nail, how accurately inserting safely the ilium nail in art, avoid the important feature such as injured blood vessel, nerve in art as far as possible, is also puzzlement doctor's a great problem.Because the ilium anatomical structure is complicated, and adjoin vitals, nerve and blood vessel, iliac screw is longer, in inserting process, as inaccurate in entry point and nail road regioselective, very easily make iliac screw pass sclerotin, important organ, nerve and blood vessel in the damage pelvic cavity; Moreover, existing ilium nail entry point often is chosen in posterior superior iliac spine, for some Sacral Tumors resections and the regression of osteoporotic waist sacrum, can't carry out the fixing patient of rumpbone, in art for appearing the ilium entry point, easily cause to the far-end dissection scope excessive, surrounding soft tissue and muscle are caused unnecessary damage, patient's post-operative recovery is affected greatly.
Summary of the invention
Defective or deficiency for above-mentioned prior art existence, the object of the invention is to, a kind of waist ilium joint control is provided and adopts this waist ilium joint control to carry out waist ilium associating fixing means, can significantly improve constant intensity in lumbosacral section and pelvis, organize dissection scope and local wound to reduce in operation process, reduce the complication such as the waist sacrum is fixed unsuccessfully, pseudoarticulation formation, be beneficial to the stable fixing of waist sacrum, pelvis.
In order to realize above-mentioned task, the present invention takes following technical solution:
