Limited data suggest that greater FRAX-derived fracture probability is associated with incident falls at least in elderly men. Our aim was to examine the association of FRAX-derived fracture probability with the risk for subsequent fall-associated hospitalizations. We identified individuals aged 40 yr or older at the time of baseline DXA with FRAX-derived major osteoporotic fracture (MOF) probability assessed through the Manitoba BMD Program. We used linkage with population-based data to identify subsequent hospitalization that included a fall diagnosis code. Sensitivity analyses examined fall-associated hospitalizations unrelated to a concurrent fracture (diagnosed within 30 d). Cox regression was used to estimate HR for time to fall-associated hospitalization according to MOF probability without and with BMD (per SD increase and also for individual variables in the FRAX tool). The study comprised 88 684 individuals, mean age 64.6 yr, 89.5% female. During mean 8.6 yr observation (total 759 963 person-years), 9715 (11.0%) individuals experienced a fall-associated hospitalization; of these, 3363 (3.8%) were unrelated to concurrent fracture. Every SD increase in MOF fracture probability was strongly associated with fall-associated hospitalization (without BMD HR, 2.47; 95% CI, 2.41-2.52; with BMD HR, 2.48; 95% CI, 2.43-2.53). No significant interaction was seen between fracture probability and follow-up time (p = .516). Findings were similar when restricted to individuals with falls unrelated to concurrent fracture, when adjusted for previous fall-associated hospitalization (last 3 yr) or self-reported fall (last 12 mo), when restricted to individuals without previous falls, and for FRAX-derived hip fracture probability. All FRAX variables except for parental hip fracture showed a positive relationship with fall-associated hospitalization.

The current analyses describe patterns of change in BMD, serum bone turnover markers, and serum and urine calcium in adults with chronic hypoparathyroidism treated with palopegteriparatide through 3 years of the PaTH Forward trial. Baseline BMD Z-scores for the LS, TH, FN, and 1/3 distal radius were above zero, indicating bone mass exceeding age-adjusted normative values. BMD decreased from these elevated baseline levels with palopegteriparatide treatment, with larger reductions during the first 26 weeks and modest declines thereafter.

Participants with lower baseline BMD (Z-scores below -1 and T-scores below -2.5) generally exhibited lesser declines in BMD versus those with higher baseline BMD.

We conducted a multicenter case-control study with cross-sectional exposure assessment to compare ulna flexural rigidity (EI), a biomechanical property correlated with whole-bone strength (R2 ≈ 0.99), estimated using cortical bone mechanics technology (CBMT), with DXA-derived BMD for discriminating prior fragility fractures in postmenopausal women.

We and others have previously reported that Pls3-deficient mice display a skeletal phenotype that unexpectedly affects only the cortical bone compartment. To better characterize the impact of PLS3 inactivation on bone (micro-)architectural parameters in humans, we retrospectively analyzed skeletal parameters obtained from male XLO patients and compared them to corresponding data from male individuals with genetically diagnosed osteogenesis imperfecta type I (OI-I). We observed no major differences between XLO and OI-I patients in baseline characteristics, laboratory parameters, or bone mineral density measurements by dual-energy X-ray absorptiometry (DXA). However, there was a significant difference between the two groups observed by high resolution peripheral quantitative computed tomography (HRpQCT). More specifically, XLO patients displayed significantly reduced cortical bone parameters, compared to both normal reference ranges and OI-I, especially at the distal radius. We also analyzed female heterozygous carriers of (likely) pathogenic PLS3 alleles, who were less affected compared to male XLO patients. However, two of them displayed osteoporotic fractures at a postmenopausal age, thus treatment with romosozumab, a monoclonal antibody targeting sclerostin, was initiated and appeared to be effective. Since another sclerostin-neutralizing antibody is currently studied for the treatment of OI patients, we crossed Pls3-deficient mice with mice carrying a high bone mass allele of Lrp5 (Lrp5A213V), which serves as a molecular mimic of anti-sclerostin therapy. We found that the presence of the Lrp5A213V allele led to significantly increased cortical and trabecular bone mass not only in wildtype but also in Pls3-deficient mice.

A jump test on a force plate measures weight-bearing power and allows the dissection of peak power into its components, force and velocity. We investigated the association between jump test power measures and major osteoporotic fractures (MOF) risk in 1841 older men (median age 84 yr). Peak jump power (W/kg body weight), force (N/kg body weight) at peak power, and velocity (m/s) at peak power were measured by jump tests on a force plate. Fractures were identified by triannual questionnaires, with all self-reported fractures confirmed by medical record. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CIs) by continuous (per one SD increment) and across quartiles of jump test measures. Participants that were excluded from the jump tests were classified into the \"lowest\" group (referent; N = 599). A total of 136 incident MOF occurred over 5 yr of follow-up. In the multiply adjusted models, one SD increment of peak power/kg body weight was associated with a lower risk of MOF (HR 0.71, 95% CI: 0.54-0.92), with a similar risk reduction observed with velocity at peak power (HR 0.76, 95% CI: 0.59-0.98). Further adjustment for femoral neck (FN) bone mineral density (BMD) did not attenuate the association. There was significant trend of decreasing MOF with increasing power and velocity. For force, only the highest quartile was significantly associated with lower risk of MOF, but this was not significant after adjusting for FN BMD. In older men, peak leg power and velocity, but not force, predicted MOF risk independent of FN BMD.
