Abstract: BACKGROUND: Abnormal changes of cervical curvature are common in cervical spondylosis. Although conservative treatment is the main treatment for cervical spondylosis, symptomatic treatment is adopted in most cases, and the correction of abnormal cervical curvature is ignored in conservative treatment.  
OBJECTIVE: To observe the clinical effect on cervical spondylosis treated by three-dimensional (3D) printing personalized cervical vertebra correction pillow combined with health education of cervical spondylosis, thermal physiotherapy, and oral drugs in early treatment.
METHODS:  A total of 33 patients with cervical spondylosis admitted in Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine from July 2019 to December 2020 were selected as the research objects. Based on health education for cervical spondylosis, thermal therapy, and routine oral drugs in early treatment, all patients were asked to use 3D printing personalized cervical vertebra correction pillow during sleep, for 24 continuous weeks. The improvement of cervical curvature (Borden’s method), the Neck Disability Index, Visual Analogue Scale score and Pittsburgh Sleep Quality Index before and after treatment were observed and the overall clinical efficacy was evaluated.  
RESULTS AND CONCLUSION: Compared with baseline data, Borden value of cervical curvature was significantly increased in the patients after 24-week treatment (P < 0.05). After treatment, Neck Disability Index, Visual Analogue Scale score and Pittsburgh Sleep Quality Index were all significantly decreased (P < 0.05). After treatment, the total effective rate of clinical efficacy was 88%. These findings indicate that based on the health education of cervical spondylosis, thermal physiotherapy and oral drugs in early treatment, the use of 3D printing personalized cervical vertebra correction pillow during sleep at night can effectively correct and restore the cervical physiological curvature, reduce the pain of patients’ neck and shoulder muscles and improve sleep quality, which is an effective method for the treatment of patients with cervical spondylosis with abnormal cervical curvature.
