Background:
Patients with type 2 diabetes (T2D) have an increased risk for vertebral fracture (VF). The aim of this study is to determine the utility of trabecular bone score (TBS) in T2D patients with VF and the relationship of TBS with serum bone turnover biomarkers (SBTBs).
Methodology:
Postmenopausal T2D female patients were prospectively enrolled. All patients received: (1) dual-energy X-ray absorptiometry exam for bone mineral density (BMD), T-score, and TBS values; (2) lateral lumbar spine radiographs for VF assessment; and (3) SBTBs: bone specific alkaline phosphatase and Beta-C-Terminal telopeptides. BMD, T-score, TBS, and SBTBs were tested for association with VF.
Results:
The study included 285 T2D patients (mean age = 61.1 years) and 32 patients had VF (11.2%). TBS had the strongest association with VF in T2D patients (area under curve 0.775). The TBS cutoff values for VF are 1.279 in T-score ≥1 and 1.236 in T-score <-1. In patients without VF, all sites of BMD and TBS are significantly associated with SBTBs, but in patients with VF, no associations are found between SBTBs and all sites of BMD and TBS.
Conclusions:
TBS can assess bone quality in the spine. The low TBS cutoff values for T2D patients with VF imply T2D does impair bone quality. Thus, TBS should be incorporated in VF risk assessment in T2D patients. In addition, a dissociated relationship between BMD and TBS with SBTBs represents imbalanced bone turnover rate and results in bone fragility and VF.

01:27Fractures: 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...

01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
01:29Bone 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...
