Lateral Mass Screw versus Transfacet Screw Fixation for Cervical Myelopathy: An Institutional Experience
Abstract: Aims and Objectives: Posterior subaxial cervical fusion with lateral mass screw and rod instrumentation is a widely used fixation technique. Subaxial transfacet screw fixation is a relatively unknown fusion technique. This study evaluated the outcomes of cervical decompressive laminectomy with lateral mass fixation versus transfacet fixation. Materials and Methods: This study compared 20 patients who underwent cervical decompressive laminectomy with lateral mass fixation to 20 who underwent transfacet fixation. The modified Japanese orthopedic association score (mJOA) scale, Nuricks grade assessment were employed to quantify the functional result. The clinical follow-up period lasted 6months. Results: Demographically males are more seen as subjects in our study, a higher impact of etiological variables on the elderly age group. There was significant difference in mJOA score preoperatively and postoperatively in both groups. There were significant changes in Nuricks functional grade in both groups upto grade 3 with little or no change in grade by either of procedure for grades 4 and 5. There was significant difference in operative time, blood loss favoring towards transfacet group. Conclusion: Both of the posterior instrumentation methods revealed similar results in terms of neurological endpoints. Traditional screw placement options may be limited due to altered anatomy caused by congenital deformity, tumor, trauma, infection, or failed lateral mass fixation. Transfacet screw placement is a good alternative option for posterior cervical fusion with good efficacy rates in comparison with traditional techniques of screw placement.
