Cervical alignment as a concept has come to the forefront for spine deformity research in the last decade. Studies on cervical sagittal alignment started from normative data, and expanded into correlation with global sagittal balance, prognosis of various conditions, outcomes of surgery, definition and classification of cervical deformity, and prediction of targets for ideal cervical reconstruction. Despite the recent robust research efforts, the definition of normal cervical sagittal alignment and cervical spine deformity continues to elude us. Further, many studies continue to view cervical alignment as a continuation of thoracolumbar deformity and do not take into account biomechanical features unique to the cervical spine that may influence cervical alignment, such as the importance of musculature connecting cranium-cervical-thoracic spine and upper extremities. In this article, we aim to summarize the relevant literature on cervical sagittal alignment, discuss key results, and list potential future direction for research using the '5W1H' framework; "WHO" are related?,

“…21,35 Several studies have reported on the changes in cervical spine alignment secondary to postural variations during radiography. 18,23 To the best of our knowledge, the present study was the first to evaluate the differences in cervical alignment between sitting cervical lateral radiographs and whole-spine lateral radiographs.…”

“…The CGH-C7 SVA (sagittal vertical axis) is frequently used to evaluate the position of the head relative to the cervical spine. 12,17 However, in different hospitals, cervical radiographs are taken using setups that involve different distances between the X-ray tube and film, 14,18-20,22,23,27 which diminishes reproducibility because the CGH-C7 SVA is affected by magnification error. 22 Instead, we used the CGH-C7 angle, defined as the angle between an imaginary vertical line and the line joining the CGH and the center of the C7 vertebral body.…”

“…Subsequently, the whole-spine lateral radiograph with clavicle positioning was taken with the patient standing and looking straight ahead, holding the elbows and wrists fully flexed and the fingers placed into the ipsilateral supraclavicular fossae, without any external support (Figure 1b). 21 The distance between the X-ray tube and the film was 1.5 m 14,16,22 for the sitting radiograph and 1.8 m 18,23 for the standing radiograph, per the protocol described in other studies. All measurements were made using a digital tool available on the hospital’s image viewing system (SYNAPSE V4.1.3; Fuji Photo Film, Co Ltd, Japan).…”

Study Design:Retrospective review of medical charts and radiographic data.Objectives:We aimed to clarify the differences in cervical alignment findings between sitting cervical lateral radiographs and standing whole-spine lateral radiographs with clavicle positioning in cervical spondylotic myelopathy (CSM) patients.Methods:We retrospectively evaluated the radiographs of 50 consecutive patients who underwent cervical surgery for CSM in our hospital. Cervical sagittal alignment was evaluated based on the C0-2 angles and C2-7 Gore and Cobb angles. Head position was evaluated in terms of the center of gravity of the head to C7 (CGH-C7) angle and the McGregor angle (ie, the angle between the McGregor line and a horizontal line). The T1-slope was also evaluated.Results:The mean values of the CGH-C7 angle and T1-slope were significantly lower, while the mean value of the McGregor angle was significantly higher on whole-spine lateral radiographs with clavicle positioning than on sitting cervical lateral radiographs. The mean values of the C0-2 and C2-7 angles did not differ significantly between the 2 radiographic positioning approaches.Conclusions:Using whole-spine lateral radiographs with clavicle positioning may result in a significantly lower T1-slope and a posterior tilt of the head. In the absence of a compensatory change in cervical alignment, clavicle positioning may force patients to adopt an upward gazing position of the head. These compensatory mechanisms should be considered while evaluating cervical alignment on whole-spine lateral radiographs with clavicle positioning. Surgical planning should take into account the effect of posture on the radiographic appearance of cervical alignment.

“…The standing position is generally considered to be a comfortable and functional posture for spinal radiography. Previous researchers have used the standing position to assess the sagittal alignment of the C-spine [16,17] However, a standing position with arms by the sides prevents adequate visualization of the lower cervical spine [18]. Therefore, one of the customized positioning techniques should be used based on patient's capabilities.…”

Background: The visualization of the lower cervical spine (C-spine), including the C7-T1 junction on lateral radiograph is a challenge due to the overlapping of the shoulder girdle. Therefore, the radiographers have adapted different positioning strategies to overcome this challenge. This study explores the current practice and perception of radiographers on positioning techniques of erect lateral cervical spine radiography in non-trauma adult patients. Methods: This prospective study was conducted with a self-administered, structured questionnaire distributed among 50 radiographers working in four selected hospitals in Sri Lanka. Results: The radiographers used weight-bearing and non-weight-bearing positioning techniques for the erect lateral C-spine radiography. Most of them employed the standing breath-holding technique for image acquisition with or without exertion. While 54% of the radiographers utilized two water-filled cans during the weight-bearing technique, 82% used holding arms back with the shoulders down and pulling as low as possible in the non-weight-bearing technique. In addition, 88% of the radiographers believed that the weight-bearing position could increase the visibility of the C-spine. Almost all the radiographers (100%) stated that correct positioning instruction could improve the visibility of the C-spine. Conclusion: Radiographers have mainly used two positioning techniques of weight-bearing and non-weight-bearing for erect lateral C-spine radiography for non-trauma adult patients. In addition, most radiographers had a positive attitude toward the weight-bearing technique in the evaluation of lateral C-spine. These results highlight the importance of conducting studies to evaluate the effectiveness of the weight-bearing technique in erect lateral C-spine radiography.
