Abstract:
A single-centre cross-sectional study was performed to investigate the potential association between the presence of sarcopenia and fracture patterns in patients with a proximal femoral fracture. We identified all consecutive patients who were admitted due to proximal femoral fracture. The patient's demographic data and the presence of sarcopenia were assessed. The presence of sarcopenia was investigated preoperatively according to EWGSOP2 criteria using the SARC-F questionnaire and the hand grip strength test. According to the presence of sarcopenia, two groups were formed and analysed. We identified 70 patients who matched the inclusion criteria and were analysed in this study. In the sarcopenic group, there was a significantly higher proportion of extracapsular fractures (63.6% vs. 26.9%; p = 0.00298, z = 2.9684) with an increased proportion of pertrochanteric fractures (52.3% vs. 23%; p = 0.0164, z = 2.396) compared to the non-sarcopenic group. Also, we observed a significant difference in the proportions of femoral neck fractures between two analysed groups (36.4% vs. 73.1%; p = 0.0029, z = -2.9684). It is important to screen for sarcopenia and apply comprehensive geriatric care to all hip fracture patients, especially those with pertrochanteric fracture patterns.

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...
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...

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...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
