Purpose: Bone cement-reinforced fenestrated pedicle screws (FPSs) have been widely used in the internal fixation and repair of the spine with osteoporosis in recent years and show significant improvement in fixation strength and stability. However, compared with conventional reinforcement methods, the advantages of bone cement-reinforced FPSs remain undetermined. This article compares the effects of fenestrated and conventional pedicle screws (CPSs) combined with bone cement in the treatment of osteoporosis.

Forensic age estimation is performed by assessing pulp chamber constrictions due to physiological age-related changes in dental radiographs; however, the estimated ages occasionally deviate from the actual ages. In particular, long-term steroid users tend to demonstrate pulp chamber constrictions in all teeth. Because this is uncommon among younger age groups, caution should be exercised when evaluating pulp chamber constriction.

The cervical uncinate process is a unique structure of the cervical spine that undergoes significant changes in its morphological characteristics with age, and these changes may be related to osteoporosis. This study aimed to observe the distribution of cancellous bone in the cervical uncinate process and its morphological features using micro-computed tomography (Micro-CT) to gain a deeper understanding of the morphological characteristics of the uncinate microstructure. We performed Micro-CT scans on 31 sets of C3-C7 vertebrae, a total of 155 intact bone samples, and subsequently used the measurement software with the Micro-CT system to obtain parameters related to the cancellous bone of the uncinate process.

Aromatase deficiency (ORPHA:91; OMIM: 613,546) is a rare, autosomal recessive disorder due to loss of function mutations in the CYP19A1 gene, described in both genders with an estimated incidence below 1/1000000. While in female the clinical manifestations generally occur at birth or in early infancy, and mainly involve sexual characteristics, in men clinical signs of aromatase deficiency mostly occur in puberty and especially in late puberty, so that diagnosis is generally established after the second decade due to tall stature, unfused epiphyses and reduced bone mass. Here we review the available information concerning the skeletal and extraskeletal phenotype and the clinical management of bone health in patients with aromatase CYP19A1 gene mutations.

Patients with radiographic axial spondyloarthritis (r-axSpA) experience a higher prevalence of fragility fractures, though the pathophysiology of osteoporosis associated with this disease remains poorly understood. The objective of this study was to evaluate the histomorphometric data in r-axSpA patients. Male r-axSpA patients up to 55 years old were enrolled in this cross-sectional study.
