Clinical Efficacy Analysis Of Anterior Cervical Subtotal Vertebrectomy Decompression With Intervertebral Fusion And Fixation Surgery In The Treatment Of Heics

Objective: To evaluate and analysis clinical efficacy and its influencingfactors of anterior cervical subtotal vertebrectomy decompression with fusionand fixation in the treatment of Hyperextension injuries of the cervical spine(HEICS).and further to explore the recognition process, Pathogenesis,clinical characteristics, Surgical treatment method and its advantages.provide reference for clinical treatment of Hyperextension injuries of thecervical spine.Methods: A retrospective analysis was made on39patients who acceptanterior cervical subtotal vertebrectomy decompression with fusion andfixation surgery from January2010to August2013in Affiliated Hospital ofShandong University of Traditional Chinese Medicine. Using the AmericanSpinal Injury Association (ASIA) classification of spinal cord injury and theJapanese Orthopaedic Association improved JOA score rate to assess surgicalefficacy. According to a number of factors that may affect surgical efficacy,such as age, timing of surgery, for statistical analysis, reveal its impacton surgical efficacy.Result: A review6months after surgery show that all patients had varyingASIA grade improvement over the admission，No surgical complications such aspseudo articulation formation，graft dislocation，screw and plates loosing or broken happened． no intractable neck pain occurred. According toHirabayashi method to assess JOA score improvement rate:13cases areexcellent,21cases are good,5cases are average. The superior rate was88%.The statistical analysis showed that age (P <0.01), the timing of surgery (P<0.05), cervical degeneration (P <0.01), cervical spinal cord MRI signalchange (Ⅰand Ⅱ: P <0.05,Ⅰand Ⅲ: P <0.01,Ⅱand Ⅲ: P <0.05) were allassociated with surgical efficacy.Conclusion: Anterior cervical subtotal vertebrectomy decompression withfusion and fixation surgery was a safe and effective way for the treatmentof Hyperextension injuries of the cervical spine, With shorter operative time,less blood loss, high fusion rate, fewer complications and so on. age, timingof surgery, cervical degeneration and spinal cord MRI signal change all havevarying degrees of impact on the efficacy of surgery.
