zos This bibliometric study evaluated the scientific impact of papers dealing with osteoporosis detected by dental panoramic radiographs by performing citation analysis and cited reference analysis. Retrospective data was extracted from the Web of Science Core Collection database and imported into VOSviewer, CRExplorer, and CitNetExplorer for analyzing semantic contents, cited references, and temporal citation network. The 280 relevant papers identified were cited 4874 times, having an h-index of 38 and 17.4 citations per paper. The top five major contributing countries were Japan (n = 54, 19.3%), USA (n = 43, 15.4%), ...

A 44-year-old woman with a history of hypertension and partial gastrectomy presented to the emergency department with low thoracic back pain of 2  days' duration without red flag symptoms. The physical examination was significant for point tenderness to palpation in the lower thoracic spine without overlying skin changes or neurologic symptoms. Considering her large body habitus and history of gastrectomy, a thoracic radiograph was obtained to rule out compression fracture due to osteoporosis (Figure 1).

CONCLUSIONS: A high index of suspicion is needed to diagnose sacral insufficiency fracture after LS arthrodesis. A trial of conservative management is reasonable for select patients; potential surgical indications include refractory pain, neurological deficit, fracture nonunion with anterolisthesis or kyphotic angulation, L5-S1 pseudarthrosis, and spinopelvic malalignment. Lumbopelvic fixation with iliac screws may be effective salvage treatment to allow fracture healing and symptom improvement. High-risk patients may benefit from prophylactic lumbopelvic fixation at the time of index LS arthrodesis. PMID: 32217798 [P...

AbstractPurpose of ReviewThis review discusses imaging modalities for fracture repair assessment, with an emphasis on pragmatic clinical and translational use, best practices for implementation, and challenges and opportunities for continuing research.Recent FindingsSemiquantitative radiographic union scoring remains the clinical gold standard, but has questionable reliability as a surrogate indicator of structural bone healing, particularly in early-stage, complex, or compromised healing scenarios. Alternatively, computed tomography (CT) scanning enables quantitative assessment of callus morphometry and mechanics through ...

Authors: Li J, Karim MA, Che H, Geng Q, Miao D Abstract To investigate whether p16 deletion can prevent osteoporosis caused by estrogen deficiency, we first confirmed that p16 protein expression levels were significantly up-regulated in bony tissue of ovariectomized (OVX) wild-type mice. Eight-week-old wild-type and p16-/- mice were then sham-operated or bilateral OVX. After 12 weeks, the bone phenotypes of all models were analyzed by radiography, micro-computed tomography, histology, immunohistochemistry, and molecular biology. The results showed that p16 deficiency could rescue OVX-induced osteoporosis by signifi...

This study aimed to investigate whether USF concomitant with low-energy DRF was associated with the bone mineral status and the degree of radiographically observed pretreatment radius displacement in Japanese adults above 50  years of age.MethodsThe study subjects were 45 (44 female, 1 male) consecutive patients aged>  50 years with DRF caused by falls from June 2015 to May 2016. Fractures due to high-energy injuries were excluded. Patients were divided into two groups according to the presence or absence of USF. Radius displacement was assessed on anteroposterior and lateral radiographs by measuring ul...

AbstractPurpose of ReviewTo summarize the bone findings, mainly bone mass and fracture risk, in Ehlers –Danlos syndromes (EDS).Recent FindingsLow bone mineral density and fractures seem to be frequent in some of the rare EDS types (kyphoscoliotic, arthrochalasia, spondylodysplastic, and classic-like EDS). For the more prevalent hypermobile and classic EDS types, some case –control studies found mildly decreased bone mineral density, but it was not clear that fracture rates were increased. Nevertheless, abnormalities in vertebral shape seem to be common in classical and hypermobile EDS types. In a cohort of indi...

Objective: Immunological abnormalities, the resulting endocrinopathies and their treatments may impact bone health in patients with autoimmune polyendocrinopathy–candidiasis–ectodermal dystrophy (APECED, APS1). The aim of the present study was to describe skeletal characteristics in patients with APECED and the prevalence and risk factors of compromised bone health.Patients and methods: We performed a cross-sectional study on 44 patients (27 females) with APECED and 82 age-, gender- and ethnicity-matched control subjects (54 females). We determined the prevalence of osteoporosis by dual-energy X-ray absorptiome...

ConclusionsIn contrast to the well ‐established association between black race and knee or hip OA, odds of hand OA are lower in black versus nonblack subjects, which is not mediated by known hand OA risk factors. Future mechanistic works are warranted to determine the mediating protective factors for hand OA among the black subject s.

Abstract BACKGROUND: The concurrent presence of sarcopenia and osteoporosis may enhance fracture risk. AIM: To evaluate the association between sarcopenia, osteoporosis, or the concurrent presence of both the conditions (osteosarcopenia) and the burden (number and severity) of vertebral fractures in women with hip fracture. DESIGN: Cross-sectional study. POPULATION: We studied 350 women with subacute hip fracture. METHODS: Lateral radiographs of the spine were taken 18.2±4.5 days after fracture occurrence and the spine deformity index (SDI) was calculated. Body composition was assessed b...
