Alternatively, the increase in lumbar spine BMD may in part be confounded by the progression of formation of ligament calcifications and fusion of facet joints [ 5, 29, 30].
Since the anterior-posterior lumbar spine BMD measured by DXA can be overestimated by the presence of syndesmophytes, ligament calcifications, and fusion of facet joints in these patients [ 1, 23– 25], we used hip BMD T-score for further analyzing the relevant factors of osteoporosis.
Acvr1 R206H/+ mice also showed the full spectrum of congenital malformations observed in individuals with FOP: fusion of subaxial cervical facet joints, costovertebral malformations, and osteochondromas of the proximal tibias and scattered other sites.
CT can always accurately demonstrate fractures of the posterior elements or non-fusion of the facet joints.
Our analysis shows that cartilaginous fusion and ankylosis of facet joints in AS patients is not mediated by chondrocyte hypertrophy but rather promoted by cartilage degeneration.
We report a case that is unusual in many aspects such as the site of tumour origin within the rib; associated myelopathic symptoms; occurrence in a middle-aged patient; and the erosion and fusion of the vertebral pedicle, facet, and body due to tumour extension.
They can be referred to Australidelphia because they exhibit fusion of the ectal and sustentacular facets, forming the australidelphian 'continuous lower ankle joint pattern', and subdivision of the calcaneocuboid facet into three distinct facets [5], [34].
It is hypothesized that strepsipteran eye evolution involved a reduction in the number of facets, however it remains unclear if eyelets evolved by enlarging individual facets or by the fusion of several facets.
The number of facets varies.
"It has lots of facets, lots of meanings.
Omnivores have an intermediate number of facets.
