Purpose Clinical observations suggest that endplate shape and size are related to complications of disc arthroplasty surgery. Yet, the morphology of the vertebral endplate has not been well defined. This study was conducted to characterize the morphology of lumbar vertebral endplates and to quantify their morphometrics using radiographic, visual and digital measures. Methods A total of 591 vertebral endplates from 76 lumbosacral spines of men were studied (mean age 51.3 years). The shape of the vertebral endplates was classified as concave, flat and irregular, and was evaluated from both radiographs and cadaveric samples. Each endplate was further digitized using a laser scanner to quantify diameters, surface area and concavity for the whole endplate and its components (central endplate and epiphyseal rim). The morphological characteristics and morphometrics of the vertebral endplates were depicted. Results In both radiographic and visual assessments, more cranial endplates (relative to the disc) were concave and more caudal endplates were flat at all disc levels (p \ 0.001). On average, the mean concavity depth was 1.5 mm for the cranial endplate and 0.7 mm for the caudal endplate. From L1/2 down to L5/S1 discs, the vertebral endplate gradually changed into a more oval shape. The central endplate was approximately 70 % of the diameter of the whole endplate and the width of the epiphyseal rim varied from 3 to 7 mm. Conclusions There is marked morphological asymmetry between the two adjacent endplates of a lumbar intervertebral disc: the cranial endplate is more concave than the caudal endplate. The size and shape of the vertebral endplate also vary considerably between the upper and lower lumbar regions.

“…These variants are due to notochordal remnants. In a previous study no clinically important relationship was found between lumbar bone density, body height and weight, and prevalence of the Cupid's bow contour [63]. Limbus vertebrae results from an anterior (or posterior) intraosseous herniation of the nucleus pulposus and was first described in detail by Neidner [64].…”

As populations age osteoporosis becomes an increasingly important public health issue. Among osteoporotic fractures vertebral fractures are of particular relevance: they are the most common fractures, frequently are asymptomatic but have an important influence on prognosis and morbidity in the osteoporotic patient. Previous studies have suggested that these fractures are frequently not diagnosed and that radiologists miss a high percentage of osteoporotic, vertebral fractures present on lateral chest radiographs. The aims of this review are (1) to emphasize the important role that radiologists play in the accurate and clear reporting of vertebral fractures, (2) to provide guidance in assessing these fractures in radiographs, MRI and computed tomography imaging of the vertebral spine and (3) to sensitize the radiologist in diagnosing fractures in chest radiographs.

Cupid's bow contour of the vertebral body: evaluation of pathogenesis with bone densitometry and imaging-histopathologic correlation.

Abstract: The Cupid's bow deformity is a developmental phenomenon that is unrelated to osteopenia or mechanical stress on the spine.
