Abstract:
The onset age of fracture may be useful to explore the clinical and genetic heterogeneity of fracture study. In the present study, we investigated the heritability of the onset age of wrist fracture (OAWF) in 30 female full-sib pairs. The phenotypic correlation coefficient of OAWF was 0.309 (P=0.09) for this cohort of female sib pairs, and the narrow-sense heritability (h2) was estimated to be 0.618 (P=0.09). In addition, the h2 derived from the variance component model implemented in SOLAR was 0.722 (P<0.05). This study, for the very first time, suggested that OAWF is under genetic control and thus potentially helps clarify genetic heterogeneity of wrist fracture.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
