Asymptomatic patients with early radiographic signs of OAH have been reported to have an elevated FN BMD, leading to the conclusion that not only cartilage but also adjacent bone is affected in OAH (Bruno et al. 1999).
In particular the following bones were affected: tibial swelling occurred in six patients, ulnar and radial in four, femoral in three, fibular in three, mandibular in two, humeral in two, and clavicular in one (Table 1).
The carpal bones were affected by primary tumours in 5.5% of cases and of these 8.6% were malignant.
In particular, in the field of oral and maxillofacial surgery, where comparatively small but anatomically complex bones are affected, reconstruction in terms of an esthetic and functional outcome is often difficult to achieve [ 3].
In order to establish how quickly bone structure and volume were affected in young (6-week old) animals, we characterised the effects of a single dose of zoledronic acid (100 μg/kg, ZOL) or PBS 1, 3, 5 and 10 days post treatment by μCT analysis.
Bone densitometric studies proved that all sites of bone including axial and appendicular skeleton were affected in patients with hyperthyroidism [ 33], but Van de ven and Erdtsieck studies (2008) revealed that changes in cortical bone (appendicular skeleton like femur and radius) were more prominent than cancellous bone (axial skeleton as spine) [ 4].
Bone densitometry analysis performed on the tibiae of 1 and 2 month-old wild-type and dtd mice showed that not only bone size, but also bone quality is affected in mutant mice.
The compromised intra-fibrillar mineralization observed provides a mechanism by which early bone mineralization is affected in hyperglycemia.
In Kang and colleagues' article, bone colonization was affected in the transfectants while adrenal colonization was not impacted by overexpression of these genes.
