doi:10.3969/j.issn.1006-7795.2019.04.006

Abstract

Abstract: Objective To improve the open-door laminoplasty based on the preservation of the semispinalis cervicis, and to investigate the curative effect and to explore whether the complications can be reduced. Methods Reconstruction group(45 cases) and common group (39 cases), followed up for 18-24 months. The range of motion, Japanese Orthopedic Association Scoring System (JOA) score and severity of axial symptoms were compared after surgery. Results There was no significant difference in the loss of range of motion between the two groups (9.4°±4.1° vs 11.6°±7.8°) and the recovery rate of JOA score (57.7% vs 54.4%) (P>0.05). However, there was a significant difference between the incidence of axial symptoms before and after surgery of the two groups (P<0.05). Conclusion Reconstruction of the spinous processes of C₄_-7 can further reduce the incidence of axial symptoms while retaining the C₂ spinous process.

Key words: cervical spondylosis, laminoplasty, laminectomy
