Abstract
Objectives:To analyze the prognosis of patients with low back pain according to the severity of abnormal lumbar lordotic angle and Ferguson's angle.

Methods: Data from electronic medical record of a total of 199 patients hospitalized in Korean medicine hospital were analyzed. With the sagittal view of lumbar spine X-ray, lumbar lordotic angle was defined as the angle between the superior endplate of L1 with the inferior endplate of L5. Ferguson¡¯s angle was defined as the angle between the superior surfaces of the sacral with a horizontal line. ¡®Measure Cobb¡¯s Angle Tool¡¯ of ¡®INFINITT PACS¡¯ was used to measure both angles. Lumbar lordotic angle and Ferguson's angle were subdivided into five sections. The number of days from onset and the duration of hospitalization were analyzed in each section.

Results: Severe hypolordotic lumbar lordotic angle group were found to have longer medical history and hospitalization duration than the control group. The ratio of long-term hospitalization (over 15 days) and chronic medical history (over 180 days) of patients with severe hypolordotic Ferguson¡¯s angle were significantly higher than the control group. The ratio of patients with chronic medical history (over 180 days) was significantly higher in severe hyperlordotic Ferguson's angle group than the control group.

Conclusions: Severe hypolordotic lumbar lordotic angle was related to patient¡¯s prognosis. Both severe hyperlordotic and severe hypolordotic Ferguson¡¯s angle were found to be related to patient¡¯s prognosis. However, a moderate loss of lumbar lordotic angle and Ferguson¡¯s angle was not related to prognosis of low back pain patients.
