“…While providing sufficient stability, it avoids friction with surrounding soft tissues and reduces the incidence of postoperative foreign body sensation and swallowing disorders. 7 At the same time, artificial disc replacement can retain the mobility of the replaced segment relative to that after ACDF and does not cause increased stress in adjacent segments after cervical fusion. 8 This approach can retain the overall range of motion (ROM) of the cervical spine and the ROM of replaced segments, and patients have a greater chance of obtaining good segmental ROM in the long term postoperatively.…”

“…The total score of the 5 parameters is the GAP score which divides the patients into 3 groups: a GAP score of 0–2 was defined as the proportioned group; a GAP score of 3–6 was defined as the moderately disproportioned group; those with a GAP score of 7–13 were defined as the severely disproportioned group [ 8 ]. Research has found significant age, gender, and racial differences in spinopelvic parameters [ 14 , 15 ]. Therefore, the ideal spinopelvic parameters we adopted were based on healthy individuals in China reported by Ma et al [ 16 ].…”

Study design The GAP score predicted post-operative mechanical complications more effectively whereas SRS-Schwab classification improved evaluation of postoperative PROMs. Objective The study compared the GAP Score and SRS-Schwab Classification in predicting surgical outcomes for adult spinal deformity (ASD) and elucidated whether both systems should be included in the preoperative planning. Materials and methods Radiographic measurements and health-related quality of life scores at baseline, 6 weeks after surgery, and the last follow-up were collected from a cohort of 69 ASD patients subjected to long segment spinal fusion surgery after they were grouped by GAP score and SRS-Schwab classification respectively. Fisher's exact test and receiver operator characteristic (ROC) curve analysis was used to compare the incidence of mechanical complications and the discriminant capacity during revision surgery between the two groups. Postoperative patient-reported outcomes measures (PROMs) were compared by one-way ANOVA, and the proportions of MCID achieved for PROMs compared by chi-square test between the two groups. Results The overall incidence of mechanical complications and revision surgery were 42% and 8.7%. Both GAP score and its categories predicted mechanical complications and revision surgery, but the GAP score system could not predict the improvements of PROMs. The SRS-Schwab classification could predict the occurrence of postoperative mechanical complications and improvements of postoperative PROMs between the aligned, moderately misaligned and severely misaligned groups (P < 0.05). Conclusion Hence, a comprehensive surgical strategy for postoperative planning may improve patients’ quality of life and minimize mechanical complications. Graphical Abstract

Purpose The “normal” cervical spine may be non-lordotic shapes and the cervical spine alignment targets are less well established. So, the study was to propose novel classification for cervical spine morphologies with Chinese asymptomatic subjects, and to address cervical balance status based on the classification. Method An overall 632 asymptomatic individuals on cervical spine were selected from January 2020 to December 2022, with six age groups from 20–30 year to 70 plus group. Cervical alignment contained C2-7 cervical lordosis (C2-7 CL) and T1 slope (T1S), together with C1-2 CL, C2-4 CL, C5-7 CL, C2S, cervical sagittal vertical axis (CSVA), thoracic inlet angle (TIA) and neck tilt (NT). C2-7 cervical lordosis was regarded as primary outcomes. To identify groups with similar cervical alignment parameters, a 2-step cluster analysis was performed. Results C2-7 CL, T1S, CSVA, TIA and NT increased by age and mean value of them were larger in male than female group. Four unique clusters of female lordotic cluster, female kyphotic cluster, male lordotic cluster and male kyphotic cluster were classified mainly based on gender and C2-C7 CL. T1S was the independent influencing factor for C2-7 CL in all individuals and C2-7 CL = -28.65 + 0.57 × TIA, which varied from clusters. Although interactions among cervical parameters, it showed the alignment was more coordinated in lordotic groups. Conclusions The cervical sagittal profile varied with age and gender. Four clusters were naturally classified based on C2-7 CL and gender. The cervical balance status was addressed by C2-7 CL = − 28.65 + 0.57 × TIA.
