Prevalence and Predictors of Osteoporosis Risk in Orthopaedic Patients

Abstract

Level I, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.

Parathyroid hormone (1‐34) compensates the negative effect of smoking around implants

“…Clinical studies have demonstrated that smoking (Rozental et al. ) and estrogen deficiency (Popat et al. ) are important determinants for low bone density.…”

“…Clinical studies have demonstrated that smoking (Rozental et al 2010) and estrogen deficiency (Popat et al 2009) are important determinants for low bone density. On account of this close relationship, the impact of smoking on estrogen levels, bone remodeling markers, vitamin D-PTH axis, and other sex hormones has been extensively investigated.…”

“…), and osteoporosis (Ward & Klesges ; Rozental et al. ). Thus, this study aimed to investigate the influence of subcutaneous administration of PTH (1‐34) on bone around titanium implants inserted in rats submitted to CSI.…”

“…In general, it has been observed that PTH (1-34) exerts a positive effect, favoring bone formation, despite the presence of bone catabolic factors. However, there is lack of evidence evaluating PTH (1-34) in the presence of tobacco, one of the factors most investigated, in clinical studies, with relation to poor bone healing, osteopenia (Popat et al 2009), and osteoporosis (Ward & Klesges 2001;Rozental et al 2010). Thus, this study aimed to investigate the influence of subcutaneous administration of PTH (1-34) on bone around titanium implants inserted in rats submitted to CSI.…”

Fracture — A Risk Factor for Development and Progression of Osteopenia and Osteoporosis

“…Имеется обширная доказательная база, что пере-ломы в области лучевой кости в типичном месте, дис-тальном отделе плечевой кости, позвоночнике и прок-симальном отделе бедренной кости ассоциируются с повышением риска последующего перелома, что явля-ется отражением снижения МПК после предшествую-щего перелома [23,61].…”
