Impaired bone formation in ovariectomized mice reduces implant integration as indicated by longitudinal in vivo micro-computed tomography.

PLoS One 2017 14;12(9):e0184835. Epub 2017 Sep 14.

Institute for Biomechanics, ETH Zurich, Zurich, Switzerland.

Although osteoporotic bone, with low bone mass and deteriorated bone architecture, provides a less favorable mechanical environment than healthy bone for implant fixation, there is no general agreement on the impact of osteoporosis on peri-implant bone (re)modeling, which is ultimately responsible for the long term stability of the bone-implant system. Here, we inserted an implant in a mouse model mimicking estrogen deficiency-induced bone loss and we monitored with longitudinal in vivo micro-computed tomography the spatio-temporal changes in bone (re)modeling and architecture, considering the separate contributions of trabecular, endocortical and periosteal surfaces. Specifically, 12 week-old C57BL/6J mice underwent OVX/SHM surgery; 9 weeks after we inserted special metal-ceramics implants into the 6th caudal vertebra and we measured bone response with in vivo micro-CT weekly for the following 6 weeks.

Division of Analytical Bio-Medicine, Graduate School of Medicine, Ehime University, Shitukawa, Toon city, Ehime, Japan.

Teriparatide [human parathyroid hormone (1-34)], which exerts an anabolic effect on bone, is used for the treatment of osteoporosis in patients who are at a high risk for fracture. That the once-daily administration of teriparatide causes an increase in cortical porosity in animal models and clinical studies has been a matter of concern. However, it is not well documented that the frequency of administration and/or the total dose of teriparatide affect the cortical porosity. Read More

Carotid Stent Fracture from Stylocarotid Syndrome.

J Radiol Case Rep 2016 Jun 30;10(6):1-8. Epub 2016 Jun 30.

Department of Radiology, University of Mississippi Medical Center, Jackson, MS, USA.

Eagle syndrome is a rare condition resulting from elongation of the temporal styloid process or calcification of its associated stylohyoid ligaments. Although usually presenting with pain or odynophagia, Eagle syndrome has been reported to cause a multitude of neurologic symptoms or vascular complications, some of which can be life-threatening. We present a case in which an endovascularly placed internal carotid artery stent in close proximity to a calcified stylohyoid ligament resulted in stent fracture with subsequent stent and vessel occlusion.

Local administration of a hedgehog agonist accelerates fracture healing in a mouse model.

Biochem Biophys Res Commun 2016 Oct 28;479(4):772-778. Epub 2016 Sep 28.

Division of Clinical Biotechnology, The University of Tokyo Graduate School of Medicine, Bunkyo-ku, Tokyo, 113-0033, Japan; Department of Bioengineering, The University of Tokyo Graduate School of Engineering, Bunkyo-ku, Tokyo, 113-8656, Japan. Electronic address:

Bone fracture healing is processed through multiple biological stages including the transition from cartilaginous callus to bony callus formation. Because of its specific, temporal and indispensable functions demonstrated by mouse genetic studies, Hedgehog (Hh) signaling is one of the most potent signaling pathways involved in these processes, but the effect of Hh-signaling activation by small compounds on the repair process had not yet been addressed. Here we examined therapeutic effects of local and one shot-administration of the Hh agonist known as smoothened agonist (SAG) on bone fracture healing in a mouse model. Read More
