Abstract

Background: Tissue engineering development has become a highlight in recent decades. One of the key areas of focus is producing mature bone tissue to overcome orthopedic problems, such as bone defects. Various cultures have been implemented on stem cells; some induce osteoblastic differentiation markers, while others have the opposite effect. Microgravity has been proven in several studies to inhibit the expression of osteogenic differentiation markers. Conversely, hypergravity is expected to have the opposite impact, supporting stem cells in the osteogenesis pathway. Methods: A literature search was conducted using online databases including Sciencedirect, PubMed, and Proquest, covering the period from 2008 to 2022. This search considered only experimental studies published in English. The keywords used in this research were "hypergravity" and "mesenchymal stem cell." All acquired data were processed and analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (2020). Results: Initially, 190 studies were collected from online databases based on relevant keywords. After screening, 5 studies were included in the final analysis, focusing on hypergravity treatment and its effects on mesenchymal stem cells (MSCs). Conclusion: Hypergravity shows a significant and strong impact on osteoblastic differentiation. This study revealed that a gravity force of 30G and a culture duration of 7 to 14 days are the most optimal combination for inducing osteoblastic differentiation in MSCs.

Abstract

Implant failure and acetabular protrusion are significant complications following Austin Moore prosthesis insertion, particularly in elderly patients with hip fractures. Total hip arthroplasty (THA) offers superior outcomes compared to hemiarthroplasty (HA) but comes with its own set of challenges. Understanding the risk factors and implications of these complications is crucial for choosing effective management.  In this article, we report a 76-year-old woman who presented with severe left hip pain post-fall, eight years after HA with an Austin Moore prosthesis due to a trochanter fracture. The patient was able to walk with a walker before the fall. Physical examination revealed tenderness and limited range of motion. Radiographic imaging confirmed acetabular protrusion and AMP neck fracture. Conversion to THA using a hybrid system was performed successfully, with the patient exhibiting no post-operative complications. This case report showed that implant failure and acetabular protrusion pose complex challenges, exacerbated by patient demographics, implant design, and bone quality. THA emerges as a preferred option due to its superior outcomes, although conversion from HA is associated with increased risks. Early diagnosis and intervention, as well as a multidisciplinary approach and careful consideration of patient-specific factors, are crucial for optimizing patient outcomes and quality of life.
