Objective:
The aim of this study is to identify the dependence of the result of surgical treatment of patients of elderly and senile age with fractures of the proximal femur on the characteristics of the response cytokine-mediated regulatory response to trauma and surgery.
Patients And Methods:
Materials and methods: In 74 patients after hip arthroplasty, serum levels of bone metabolism markers were determined using enzyme-linked immunosorbent assay. Patients were divided into 2 groups depending on the results of treatment.
Results:
Results: It was found that compared with group 2 (treatment outcome is worse) in group 1 (treatment outcome is better) there was a greater number of correlations. In group 1, correlations were found between OPG and RANKL (r = 0.88; p = 0.000), OPG and OPG/RANKL (r = 0.44; p = 0.006), TGF-β1 and OPG/RANKL (r = 0.66; p = 0.000) , IL-6 and OPG (r = 0.67; p = 0.000), IL-6 and RANKL (r = 0.53; p = 0.001), IL-6 and OPG/RANKL (r = 0.39; p = 0.016). In group 2, only between OPG and OPG/RANKL (r = 0.72; p = 0.000), RANKL and OPG/RANKL (r = -0.53; p = 0.0007). In patients of group 2, there was a decrease in the level of OPG relative to the control and a less significant increase in TGF-β1 and IL-6 relative to group 1.
Conclusion:
Conclusion: The prognosis of the results of treatment of patients with proximal femur fractures is largely determined by the nature of the adaptive response to injury and theimplant, the synchronism of the mechanism of stress remodeling of the bone. A less favorable prognosis after arthroplasty is associated with exacerbation of the initial metabolic disorders in the bone tissue due to severe cytokine-mediated dysfunction of the regulatory pathways.

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...

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...
