This study aimed to investigate the profiles of and correlation between objective and subjective short-term outcome assessments after open-door laminoplasty for CSM. Methods We retrospectively analyzed surgical outcomes in 129 consecutive CSM patients who underwent open-door laminoplasty in Peking University Third Hospital from February 2008 to November 2011. Both objective and subjective assessments were evaluated before surgery, 3 months after surgery, and 1 year after surgery. We then analyzed the profiles of and correlation between objective and subjective short-term outcomes. Results The Modified Japanese Orthopaedic Association （mJOA） score was significantly improved at 3 months （P〈0.01） and 1 year （P〈0.01） after surgery. Bivariate Logistic regression showed that sensory improvement contributed more to the recovery rate than motor function improvement at 3 months after surgery, while motor function contributed more to the recovery rate at 1 year after surgery. On the subjective assessment （the short form （SF）-36）, there was no significant improvement at 3 months after surgery （P〉0.05）, while physical function （PF）, role-physical （RP）, and social function （SF） were notably improved at 1 year after surgery （P〈0.01）. Improved mJOA score correlated with improvements in PF, RP, bodily pain, general health （GH）, vitality （VT）, and SF （P〈0.05） at 3 months after surgery; PF, GH, VT, and SF were associated with improved mJOA scores at 1 year after surgery. Conclusions Patients benefit from surgery by postoperative restitution of neurological function with early recovery of sensory function, followed by a gradual transition to motor function improvement. At the early stage of recovery, improvement in the mJOA score essentially correlated with improvements in the physical domains of the SF-36, while at the later stage, mJOA score improvement was associated with improvements in both mental and physical domains of the SF-36.Chin med J 2014;127（14）：2659-2663展开更多
