Clinical Efficacy On The Treatment Of Far Lateral Lumbar Disc Henriation With Unilateral Pedicle Cage Interbody Fusion Of Internal Fixation

Objective:To exploe the clinical result of line of bone marrow remove nuclearfusion (or cage bone fusion) unilateral using pedicle screws treatment for the extremelateral disc herniation after failure of conservative therapy.Methods: According to theinclusion criteria and exclusion criteria,20patients with the very type of intervertebral discwho underwent operative treatment between April2009and October2011in AffilatedHospital of Shan dong university of traditional Chinese medicine were included in thisstudy.out-patient questionnaire, physical examination and radiography, were followed upmore than1year after surgery by phone, mail, etc., met the inclusion criteria and a total of20cases with complete data. By using the visual analog scale (VAS) and modifiedJapanese Orthopaedic Association low back pain score (M-JOA) A careful analysis ofpreoperative and postoperative clinical symptoms and treatment.Result: Twenty patientsafter3to18months of follow-up, through statistical analysis, this paper concludes that thescore of VAS and JOA preoperative and postoperative follow-up the end time there was asignificant difference (P <0.05), gender and age on the end time when the effect ofadenoidectomy follow-up surgery no significant difference (P>0.05), no statisticalsignificance very lateral prolapse of lumbar intervertebral disc type of surgery theinfluence factors of the results: effect of operation curative effect and the preoperativeoutstanding nucleus pulposus oppression degree oppression merger trauma and relevantcourse position. Conclution: A lateral type prolapse of lumbar intervertebral disc treatmentis effective reduced pressure and key fully loose and the corresponding solution nerve rootin the fusion of fixed a type of intervertebral disc to expect the unilateral fixed by unilateral decompression and fusion of the fixed to reduce the between vertebra surgical trauma andthrough the lower fixed segment stiffness to reduce the incidence of adjacent segmentdegeneration, which can get with bilateral fixed similar postoperative fusion rate, in orderto improve the overall effect through a series of detailed clinical research affirms theunilateral fixed has certain biomechanical stability seriously reasonable choice of unilateralfixed treatment, so as to maximize the reduce the disease complications of proven thelength of the course of nucleus pulposus were prominent merger trauma is extremelyinfluence degree of the lateral prolapse of lumbar intervertebral disc operation of the keyfactors in the curative effect.
