Efficacy Analysis Of Cervical Spondylotic Myelopathy Treated With Posterior Unilateral Laminoplasty With Absorbable Suture Anchor

ObjectiveCervical spondylotic myelopathy treated with single door laminoplasty has beenwidely used in clinical practice.Efficacy of this surgery is well, but it has lots ofcomplications. The absorption band line anchor pin in cervical posterior single doorvertebral canal expanded keratoplasty in treatment of myelopathic type was theoperation method and clinical curative effect of cervical spondylosis.MethodsChoose between January2009and January2013, accept can absorb the anchorpin type cervical posterior single door vertebral canal plasty and traditional cervicalposterior single door myelopathic type was82cases of cervical spondylosis ofvertebral canal for treatment, patients with the above the bank of China can absorbthe anchor pin type cervical posterior single door vertebral canal plasty is set to groupA, traditional operation method for group B.All patients course in June-15years,average5.6years.Follow-up time3to18months, an average of16months.Selectedcases of standard for bone science branch of Chinese medical association ofmyelopathic type cervical vertebra disease diagnostic criteria:(1) in patients with clinical symptoms and signs consistent with cervical spinal cord injuryperformance;(2). The imaging findings of cervical spinal oppressed;(3). Rule outother diseases.Cases into the operation standard:(1) in accordance with myelopathictype cervical vertebra disease diagnosis (2). The imaging showed that three and threeor more continuous or discontinuous segmental spinal cord oppressed;(3).Conservative treatment the effect not beautiful.Postoperative follow-up time is:1,3,6,9months.According to the Japanese orthopaedic association (JOA) score standard toassess spinal cord function recovery, and the postoperative axial symptoms, toevaluate cervical curvature is lost;The X-ray, CT imaging technology assessmentdegree of vertebral canal expanded and lamina bone healing of incision.ResultFollow-up time3to18months, an average of16months.Group A averageoperation time80minutes, intraoperative blood loss, on average,90ml, no vertebralartery injury, no epidural hematoma, case closed again.Group B average operationtime of60minutes, intraoperative blood loss, on average,80ml, no vertebral arteryinjury, no epidural hematoma, then close in2cases.A, B two kinds of operativemethods in treatment of cervical spondylosis myelopathic type was significantlycurative effect, and no obvious difference in terms of neural functional recovery.Buttwo kinds of operation in the incidence of axial symptoms, cervical curvature lossprevention, A kind of operation has obvious advantages.ConclusionAbsorbable anchors improved type cervical posterior single door laminacompared with the traditional surgery, performed in the spinal cord recovery effect isthe same, but in the prevention of postoperative complications in especiallyirreplaceable superiority;Is a kind of treatment of cervical spondylosis segmental myelopathic type was more safe, effective and reliable new operation.
