“…The resulting synovial joint central and ventral gaps were, respectively, about 2 and 4 mm, which corresponded well to the reported literature (Lewin et al, 1962;Bogduk, 1997;Tanno et al, 2004). All the geometrical changes previously cited are illustrated in Fig.…”

“…They reported asymmetrical facet dimensions such as superior and inferior lumbar facet lengths, however, no information was provided on the facet joint surface areas. Although the facet joint surface areas were measured in the left and right sides in the above mentioned studies of Panjabi et al 12,13 and Tanno et al 14, no statistical comparisons between both sides were reported. Future studies on the asymmetry in the facet joint surface area will be required.…”

“…8,12–14 Panjabi et al 12,13 were the first to investigate facet joint morphology three-dimensionally in a quantitative manner. They measured heights and widths of the facet joint surface using images of the facet joint projected onto orthogonal planes and calculated the facet joint surface area by assuming facet joint shape an elliptical.…”

Study Design-In vivo measurement of lumbar facet joint surface area.Objectives-To investigate lumbar facet joint surface area in relation to age and the presence of chronic low back pain.Summary of Background Data-Facet joint surface area is an important parameter for understanding facet joint function and pathology, but information on the lumbar facet joint is limited especially in relation with age and low back pain symptoms.Methods-In vivo measurements of the lumbar facet joints (L3/L4-L5/S1) were performed on 90 volunteers (57 asymptomatic subjects, 33 chronic low back pain subjects) using subject-based three-dimensional facet joint surface CT models.Results-The facet joint surface area increased significantly at each successive inferior level. In the low back pain subjects over 40 years old, both superior and inferior facet surface areas increased except superior facets at L5/S1 compared to younger subjects. In the asymptomatic subjects over 40 years old, only the superior facets showed an increase in the L3/4 facet surface area compared to younger subjects. Conclusions-The lumbar facet areas measured in vivo in the current study were similar to previous cadaveric studies. The lumbar facet area was significantly greater at the inferior lumbar levels and also increased with age. This age related increase in the facet joint surface was observed more in the low back pain subjects compared to asymptomatic subjects. The increase in the area of the facet joint surface is probably secondary to increased load-bearing in the lower lumbar segments and facet joint osteoarthritis.

“…In extension, the joint surfaces come in contact, essentially setting the limit of that motion [43, 44]. During axial rotation, initially the joint capsule on the side opposite to the rotation is stretched and begins to resist [45-47], while at the extremes of motion the inferior articular process of the rotating vertebra comes into contact with the superior process of the still vertebra beneath [41, 44]. The most important facet joint feature is the resistance they exert to shear forces.…”

Aging of the spine is characterized by two parallel but independent processes: the reduction of bone mineral density and the development of degenerative changes. The combination of degeneration and bone mass reduction contribute, to a different degree, to the development of a variety of lesions. This results in a number of painful and often debilitating disorders. The present review constitutes a synopsis of the pathophysiological processes that take place in the aging spine as well as of the consequences these changes have on the biomechanics of the spine. The authors hope to present a thorough yet brief overview of the process of aging of the human spine.
