“…First, we included participants aged 10-19. This age range can be regarded as wide, considering that the sagittal alignment of the spine changes as a child grows and the amount of smartphone usage varies significantly with age [20][21][22][23][24][25][26][27]. For the same reason, the age of the participants has been suggested to be the most critical confounding factor in related studies [13].…”

Despite numerous attempts to correct forward head posture (FHP), definitive evidence-based screening and diagnostic methods remain elusive. This study proposes a preliminary diagnostic methodology for FHP, utilizing a noninvasive body angle measurement system as a screening test for FHP and incorporating radiological parameters for sagittal alignment. We enrolled 145 adolescents for FHP screening. The forward neck tilt angle (FNTA), defined as the angle between the vertical line and the line connecting the participant’s acromion and tragus, was measured using the POM-Checker (a noninvasive depth sensor-based body angle measurement system). A whole-spine standing lateral radiograph was obtained, and eight sagittal alignment parameters were measured. Statistical analyses of the association between the FNTA and eight sagittal alignment parameters were conducted. We used 70% of the participant data to establish a preliminary diagnostic model for FHP based on FNTA and each sagittal alignment parameter. The accuracy of the model was evaluated using the remaining 30% of the participant data. All radiological parameters of sagittal alignment showed weak statistical significance with respect to FNTA (best case: r = 0.16, p = 0.0500; cranial tilt). The proposed preliminary diagnostic model for FHP demonstrated 95.35% agreement. Notably, the model using FNTA without radiological parameters accurately identified (100%) participants who required radiographic scanning for FHP diagnosis. Owing to the weak statistical significance of the association between radiological parameters and external body angle, both factors must be considered for accurate FHP diagnosis. When a clear and severe angle variation is observed in an external body angle check, medical professionals should perform radiographic scanning for an accurate FHP diagnosis. In conclusion, FNTA assessment of FNTA through the proposed preliminary diagnostic model is a significant screening factor for selecting participants who must undergo radiographic scanning so that a diagnosis of FHP can be obtained.

“…The sagittal parameters of cervical spine are important parameters to reflect the mechanics of cervical spine and the mechanical stress in the sagittal plane of vertebral body and are important basis for evaluating the clinical status of patients and predicting the prognosis of diseases [10]. Previous studies on the relationship between sagittal parameters of cervical spine and Modic changes have found that the larger T1 slope and the smaller and C2-7 lordosis are closely related to the occurrence and development of cervical spine Modic changes [11][12][13].…”

Background Cervical sagittal parameters are important parameters that reflect the mechanical stress in the sagittal plane of the cervical spine and are an important basis for predicting the clinical status and prognosis of patients. Although it has been confirmed that there is a significant correlation between cervical Modic changes and some sagittal parameters. However, as a newly discovered sagittal parameter, there is no report on the relationship between the K-line tilt and the Modic changes of cervical spine. Methods A retrospective analysis was performed for 240 patients who underwent cervical magnetic resonance imaging scan for neck and shoulder pain. Among them, 120 patients with Modic changes, namely the MC(+) group, were evenly divided into three subgroups of 40 patients in each group according to different subtypes, namely MCI subgroup, MCII subgroup and MCIII subgroup. One hundred twenty patients without Modic changes were included in MC(−) group. We measured and compared the sagittal parameters of cervical spine among different groups, including K-line tilt, C2–C7 sagittal axial vertical distance (C2–C7 SVA), T1 slope and C2–7 lordosis. Logistic regression was used to analyse the risk factors of cervical Modic changes. Results The K-line tilt and C2–7 lordosis were significantly different between MC(+) group and MC(−) group (P < 0.05). The K-line tilt greater than 6.72° is a risk factor for Modic changes in cervical spine (P < 0.05). At the same time, the receiver operating characteristic curve showed that this change had moderate diagnostic value when the area under the curve was 0.77. Conclusion This study shows that the K-line tilt greater than 6.72° is a potential risk factor for Modic changes in cervical spine. When the K-line tilt is greater than 6.72°, we should be alert to the occurrence of Modic changes. Trial registration number: 2022ER023-1.

Background. Three main interrelated principles form the basis for modern surgery of traumatic cervical spine injuries, namely decompression, reconstruction and stabilization. Restoration of the sagittal profile is one of the basic tasks of the reconstructive stage. Currently, there are no clear recommendations for surgical management in traumatic injuries depending on the degree of deformation, and the state of sagittal balance of the injured cervical spine in the preoperative period has practically not been studied. The purpose of the work is to study the state of the sagittal profile and the degree of segmental deformation of the cervical spine following traumatic injury at the subaxial level, to determine the relationship between them and the type of injury. Materials and methods. We performed a retrospective analysis of X-ray data from 140 patients with subaxial cervical spine traumatic injury who were hospitalized at the Department of Spinal Cord Pathology of the Romodanov Neurosurgery Institute of the National Academy of Medical Sciences of Ukraine in the period from 2008 to 2018. We calculated indicators of segmental kyphosis and general cervical lordosis and determined the type of damage according to AO Spine Subaxial Cervical Spine Injury Classification System. Results. We found that the type of the damage affects the degree of segmental deformation (p < 0.001). Type A1, A2 and C injuries show the maximum kyphotic angulation: 13.51° (8.18; 20.07), 21.8° (20.12; 22.96) and 20.01° (17.52; 21.99), respectively. Injuries of type A2 and C statistically significantly differ from other types of lesions. We registered maximum values of deviations from the normal sagittal circuit in patients with injuries types A2 and C: ‒26.77° (‒32.78; ‒20.91) and ‒26.70° (‒36.30; ‒16.77), respectively. The parameters of segmental kyphosis and general cervical lordosis reveal high interdependence (r2 = 0.766, p < 0.001). We found maximum correlation in type A3, A4 and B3 injuries: ‒0.93, ‒0.91 and ‒0.97, respectively (p < 0.001). And types A1 and A2 injuries demonstrated statistically insignificant relationship (p > 0.05). Conclusions. The results show that traumatic injury of the subaxial cervical spine is characterized by a wide range of kyphotic segmental angulation values, which is largely determined by the type of injury. General cervical lordosis tends to flatten in most cases, but the degree of physiological curvature loss correlates with local deformation to some extent.
