having abnormal sagging of the spine (especially in horses)
例句
With aging, patients with OA maintained the lumbar lordotic angle and did not develop a posterior sacral slope angle. 但OA患者随着年龄增大，他们的腰椎前凸角保持不变，同时也不会出现骶骨后倾角。
Lumbar lordotic and sacral slope angles were significantly greater in patients with advanced/terminal-stage OA than the control. OA进展期/终末期病例的腰椎前凸和骶椎倾斜角较之对照组要明显大得多。
In healthy subjects, aging is associated with reduction of lumbar lordotic angle and tendency for posterior inclination of the sacrum. 在健康人群中，腰椎前凸角和骶骨后斜度数会随年龄增大而减少。
Methods.From 442 lateral cerical radiographs, 40 with lordotic, 40 with straight or sigmoid, and 40 with kyphotic alignment were selected. 方法：本研究选择442例颈椎侧位片，其中挑选了40例颈椎前凸，40例曲度变直或成S型，40例曲度侧后凸。
To the cases of jumping multilevel CSM that have a kyphotic deformity, it allows anterior decompression and reconstruction of the spine to help restore a lordotic curvature. 对于伴有颈椎后凸畸形的颈椎病患者，既能前路减压又能重建颈椎生理前凸。
A more vigorous surgical correction of the segmental kyphosis than achieved in this study might have caused the kyphotic segments to behave like the lordotic segments. 比本研究所完成的更有力的后凸节段的外科矫治，可能是使后凸节段向前曲节段一样活动。
