Abstract
Complications in bone regeneration in patients with systemic impaired bone metabolism (e.g., osteoporosis) represent a rapidly increasing clinical challenge. Alendronate and simvastatin are drugs commonly used to promote bone metabolism in osteoporotic conditions. The aim of this study was to evaluate initial bone regeneration within osseous defects grafted with beta-tricalcium phosphate (β-TCP) in adjunction with systemic coadministrations of alendronate and simvastatin (i.e., daily subcutaneous injection for 3 weeks) in healthy and osteoporotic rats. Eighty Wistar female rats were ovariectomized (OVX; n = 40) or sham operated (n = 40). Six weeks later, osseous defects (a 3-mm critical-sized defect) were created in the left femoral condyles and then grafted with β-TCP. From the day following graft installation, OVX and sham animals received for 3 weeks a daily subcutaneous injection of alendronate (50 μg/kg of body weight) and simvastatin (5 mg/kg of body weight), alone or in combination. A control group was included, which received subcutaneous saline administration. At the end of the 3 weeks, rats were euthanized and specimens (femoral condyles) were retrieved for histological evaluation and histomorphometric measurements, that is, bone area (BA%) and remaining bone graft (RBG%). In osteoporotic rats, 3 weeks of daily subcutaneous injection of combined therapy (alendronate plus simvastatin) led to a significant (p < 0.05) increase in BA% and a significant decrease in RBG% compared to healthy controls in osseous defects grafted with β-TCP (BA%: 28.6 ± 12.0 vs. 18.2 ± 7.6, RBG% 61.3 ± 11.1 vs. 70.7 ± 7.3). No significant differences in BA% and RBG% were found in the OVX rats for single treatments. Furthermore, healthy controls showed similar BA% and RBG% upon single or combined therapy compared to nontreated control rats. Daily coinjections (for 3 weeks) of alendronate plus simvastatin result in a significant enhancement of bone regeneration within osseous defects grafted with β-TCP in osteoporotic rats. Despite the expected effects on osteoporotic bone, our study did not confirm the hypothesized benefit of alendronate and simvastatin on bone regeneration in osseous defects in healthy conditions. The efficacy of the combination drug therapy on bone regeneration demands further investigation to elucidate molecular and cellular aspects underlying this therapy.

Abstract
The aim of this review was to systematically assess bone regeneration by using antiosteoporotic drugs in adjunction with bone grafting compared with controls (bone grafting without the administration of antiosteoporotic drugs). The review also evaluated statistical differences in the effect between systemic and local routes of drugs. Also, the effect of type of drugs (anticatabolic vs. anabolic) was subevaluated. PubMed and EMBASE (via OvidSP) resulted in inclusion of 60 animal studies. The studies were assessed for reporting quality and risk of bias. Outcome data from selected studies were categorized as either experimental (bone grafting with the administration of antiosteoporotic drugs) or control. Meta-analysis of selected studies was done for these outcomes: histomorphometrical bone area (BA%) and micro-CT bone volume (BV%). In this review, several animal models (52 healthy, 6 osteoporotic, and 2 both conditions) were subjected to examine the effect of antiosteoporotic drugs on bone grafting, with a predominant use of rodent species. Assessment indicates poor reporting quality and unclear risk of bias in the majority of studies. Random-effects meta-analysis revealed a significant increase in overall BA% (mean difference [MD]: 2.6, confidence interval [CI]: 2.25 to 2.92) and BV% (MD: 0.12, CI: 0.05 to 0.19) due to osteoporotic drug treatment compared with controls. For subgroups, both routes of antiosteoporotic drug administration showed similar effects on BA%. In contrast, systemic antiosteoporotic drug administration led to significantly higher BV% (MD: 6.75, CI: 5.30 to 8.19) compared with local administration (MD: 0.02, CI: -0.03 to 0.08). Further, administration of anabolic drugs significantly increased BA% (MD: 5.75, CI: 4.62 to 6.87) compared with anticatabolic drugs (MD: 1.86, CI: 1.47 to 2.26). In conclusion, both histomorphometrical and micro-CT scan analysis indicated an overall effect of using the antiosteoporotic drugs toward bone regeneration in adjunction with grafting. However, not all studies showed a positive effect and the present results need to be applied with care, as the included papers showed experimental heterogeneity for animal models. Further (pre)clinical research is warranted to explore whether drug-based strategies can be an effective adjunctive with bone grafting. Impact Statement The aim of this meta-analysis was to assess whether antiosteoporotic drugs can promote bone regeneration in adjunction with bone grafting by using preclinical animal models. Although the majority of included studies indicated poor reporting quality and unclear risk of bias, an overall positive effect of the antiosteoporotic drugs toward bone regeneration related to bone grafts can be highlighted.

Abstract
To compare the efficacy of once-weekly and once-daily subcutaneous injections of teriparatide (recombinant human parathyroid hormone 1-34) on fracture healing, 50 adult male Sprague-Dawley rats were subjected to a unilateral tibia fracture and received internal fixation with a Kirschner needle. Based on the injection dose and frequency, the rats were randomly divided into five groups (n = 10 each): subcutaneous injections of saline or 10 µg/kg/w, 20 µg/kg/w, 10 µg/kg/d, and 20 µg/kg/d teriparatide. Four weeks later, the rats were euthanatized, and the fractured tibiae were assessed using X-rays, dual-energy X-ray absorptiometry, micro-computed tomography, the three-point bending biomechanics test, and histology. Compared to the saline control group, either daily or weekly subcutaneous injections of teriparatide significantly increased bone mass, improved the bone microarchitecture, and promoted fracture healing (p < 0.05). There were no significant differences in bone mineral density (BMD), bone microstructure or bone strength between the 20 µg/kg/w and 10 µg/kg/d groups (p > 0.05). Teriparatide 20 µg weekly injections promoted bone fracture healing to the same extent as teriparatide 10 µg daily injections, which can dramatically decrease the cumulative dosage of teriparatide injections. © 2017 Orthopaedic Research Society.

Abstract
Calcific aortic vasculopathy correlates with bone loss in osteoporosis in an age-independent manner. Prior work suggests that teriparatide, the bone anabolic treatment for postmenopausal osteoporosis, may inhibit the onset of aortic calcification. Whether teriparatide affects the progression of preexisting aortic calcification, widespread among this patient population, is unknown. Female apolipoprotein E-deficient mice were aged for over 1 yr to induce aortic calcification, treated for 4.5 wk with daily injections of control vehicle (PBS), 40 µg/kg teriparatide (PTH40), or 400 µg/kg teriparatide (PTH400), and assayed for aortic calcification by microcomputed tomography (microCT) before and after treatment. In a followup cohort, aged female apolipoprotein E-deficient mice were treated with PBS or PTH400 and assayed for aortic calcification by serial microCT and micropositron emission tomography. In both cohorts, aortic calcification detected by microCT progressed similarly in all groups. Mean aortic 18F-NaF incorporation, detected by serial micropositron emission tomography, increased in the PBS-treated group (+14 ± 5%). In contrast, 18F-NaF incorporation decreased in the PTH400-treated group (-33 ± 20%, P = 0.03). Quantitative histochemical analysis by Alizarin red staining revealed a lower mineral surface area index in the PTH400-treated group compared with the PBS-treated group ( P = 0.04). Furthermore, Masson trichrome staining showed a significant increase in collagen deposition in the left ventricular myocardium of mice that received PTH400 [2.1 ± 0.6% vs. control mice (0.5 ± 0.1%), P = 0.02]. In summary, although teriparatide may not affect the calcium mineral content of aortic calcification, it reduces 18F-NaF uptake in calcified lesions, suggesting the possibility that it may reduce mineral surface area with potential impact on plaque stability. NEW & NOTEWORTHY Parathyroid hormone regulates bone mineralization and may also affect vascular calcification, which is an important issue, given that its active fragment, teriparatide, is widely used for the treatment of osteoporosis. To determine whether teriparatide alters vascular calcification, we imaged aortic calcification in mice treated with teriparatide and control mice. Although teriparatide did not affect the calcium content of cardiovascular deposits, it reduced their fluoride tracer uptake.

Abstract
Recombinant Human Parathyroid Hormone (rhPTH 1-34) administration is an effective treatment to improve bone mass in osteoporosis. The aim of this study was to develop a Tissue Engeenering Tool for bone regeneration. We evaluated the efficacy of a freeze dried rhPTH membrane in calvarial critical size defect (CSD). Forty-four Wistar female rats (body weight 150 ± 50 g) with CSD (5 mm) were divided into four groups: group 1: rhPTH membrane (rhPTHm); group 2: atelocollagen membrane (Cm); group 3: rhPTH and atelocollagen I (CrhPTHm); group 4: without any treatment (CG). All samples were evaluated on the 1st, 3rd, and 6th weeks (weeks) post-surgery by soft X-ray, histological and histometric studies. Soft X-ray results showed a radiolucent image with many irregular radiopaque areas. Histologically, rhPTHm was replaced by reticular bone (7%) since 3rd week, and lamellar bone ossicles (30%) at 6th week. Cm showed bone formation like composite bone type on week 1st, 3rd, and 6th (2%, 44%, and 41%, respectively). With CrhPTHm, bone formation was observed in all periods (2.4%, 48%, and 53%), showing statistical difference with CG in the 3rd and 6th wks (p = 0.03 and 0.01). Our results demonstrated the effectiveness of a new biomaterial called CrhPTHm because its ability to regenerate calvarial CSD. Moreover, the membrane represents a new local intermittent delivery system allowing rhPTH slow release.

Abstract
Enhancing the quantity and quality of cancellous bone with anabolic pharmacologic agents may lead to more successful outcomes of non-cemented joint replacements. Using a novel rabbit model of cancellous bone loading, we examined two specific questions regarding bone formation at the bone-implant interface: (1) does the administration of intermittent PTH, a potent anabolic agent, and mechanical loading individually and combined enhance the peri-implant cancellous bone volume fraction; and, (2) does surgical trauma enhance the anabolic effect of PTH on peri-implant bone volume fraction. In this model, PTH enhanced peri-implant bone volume fraction by 30% in loaded bone, while mechanical loading alone increased bone volume fraction modestly (+10%). Combined mechanical loading and PTH treatment had no synergistic effect on any cancellous parameters. However, a strong combined effect was found in bone volume fraction with combined surgery and PTH treatment (+34%) compared to intact control limbs. Adaptive changes in the cancellous bone tissue included increased ultimate stress and enhanced remodeling activity. The number of proliferative osteoblasts increased as did their expression of pro-collagen 1 and PTH receptor 1, and the number of TRAP positive osteoclasts also increased. In summary, both loading and intermittent PTH treatment enhanced peri-implant bone volume, and surgery and PTH treatment had a strong combined effect. This finding is of clinical importance since enhancing early osseointegration in the post-surgical period has numerous potential benefits.
