Clinical outcomes of modified versus traditional expansive open-door laminoplasty for cervical spondylotic myelopathy: A single-institution experience

Purpose To compare the surgical outcomes of modified expansive open-door laminoplasty (EOL) (C4-C6) and traditional EOL (C3-C7) in patients with cervical spondylotic myelopathy (CSM). Methods One hundred and two CSM patients were retrospectively recruited from Fujian Medical University Union Hospita...

description Purpose To compare the surgical outcomes of modified expansive open-door laminoplasty (EOL) (C4-C6) and traditional EOL (C3-C7) in patients with cervical spondylotic myelopathy (CSM). Methods One hundred and two CSM patients were retrospectively recruited from Fujian Medical University Union Hospital between March 2012 and December 2019. Seventy-one patients with CSM underwent modified EOL, and 31 patients underwent traditional EOL. The primary endpoint was axial symptoms. Results Patients who underwent modified EOL had a significantly lower incidence of axial symptoms (odds ratio: 0.273; 95% confidence interval: 0.184-0.691; p = .002). The length of hospital stay ( p = .263), and intraoperative blood loss ( p = .402) were not significantly different between the groups. Significantly more postoperative drainage was observed in patients who underwent modified EOL ( p < .001), while the cost of hospitalization in patients treated with traditional EOL was higher ( p = .011). There were significant differences between modified and traditional EOL for the changes in range of motion ( p < .001), modified Japanese Orthopaedic Association score ( p = .001), and the Nurick grade ( p = .014), while the changes of visual analogue scale ( p = .250), and the neck disability index ( p = .134) were not significantly different between the groups. Conclusion This study found modified EOL may decrease the incidence of axial symptoms in patients with CSM compared to traditional EOL.
