Objective To investigate whether lumbar lordosis (LL) and lumbar segmental lordosis (LSL) are related to sex, age, low back pain (LBP), and lumbar disc space narrowing (DSN).
Methods A total of 569 farmers were recruited. In lateral spine radiograph, LL (L1–L5) and LSL (L1, L2, L3, L4, and L5) were measured using Cobb’s method. The differences in LSL values (ΔLSL) according to the presence or absence of a DSN were calculated as LSLDSN – LSLnoDSN for each DSN level.
Results In male, the lateral spine radiograph showed significantly greater L4-LSL and L5-LSL and smaller L1-LSL and L2-LSL compared to female. LLs in the 50–59 and ≥60 years age groups were significantly smaller compared to those in the <50 years age group. In subjects with LBP, LL and L4-LSL were significantly smaller than in those without. The ΔLSLs at the disc level with DSN showed the greatest decrease: L1-ΔLSL (Δ-3.99°), L2-ΔLSL (Δ-3.31°), L3-ΔLSL (Δ-2.87°), L4-ΔLSL (Δ-3.31°), and L5-ΔLSL (Δ-4.44°) in L1/2, L2/3, L3/4, L4/5, and L5/S1 DSN, respectively. Conversely, distant ΔLSLs were inversely increased: L1-LSL (Δ0.75°) with L4/5 DSN and L2-LSL (Δ0.94°) with L5/S1 DSN.
Conclusion Sagittal plane alignment was significantly associated with sex, age, LBP, and DSN. LSLs around the levels of DSN were decreased, and there was compensational increase of LSL distant to the DSN to maintain the overall LL.

High-riding right brachiocephalic and subclavian arteries are often asymptomatic and rare vascular variations. We present a patient with high-riding right brachiocephalic and subclavian arteries that caused compressive pharyngeal and cervical esophageal dysphagia. An 82-year-old woman presented to our hospital with dysphagia that worsened with solid food. A pulsatile lump was observed on the right neck side. A videofluoroscopic swallowing study showed a deviated food bolus movement anterolaterally from the normal vertical pharyngoesophageal transition, with a filling defect in the lower pharynx through the upper esophagus. Neck computed tomography (CT) showed high-riding right brachiocephalic and subclavian arteries and a tortuous right common carotid artery located adjacent to the trachea in the cervical area. The cervical midline structures were deviated to the left neck side. A neck mass with vascular variation should be considered as a cause of dysphagia that worsens with solid food; CT should be considered to determine its cause.
