Evaluating the Effectiveness of Conventional Prostheses Against Dual-Mobility Prostheses in the Treatment of Femoral Neck Fractures in Two Separate Groups of Patients: A Clinical Trial Study.

Background: Femoral neck fracture is a common posttraumatic injury in the elderly. Currently, orthopedic surgeons conducting total hip arthroplasty (THA) for hip fractures have various prosthetic alternatives. Dual-mobility cup THA is recommended for hip fracture patients to reduce prosthesis dislocation. Therefore, the goal of this research is to evaluate the effectiveness of conventional prostheses against dual-mobility prostheses in treating femoral neck fractures in two groups of patients. Materials and Methods: The current clinical investigation involved patients with femoral neck fractures. Among approved 84 patients, 44 and 40 were undergoing conventional THA (group A) and dual-mobility THA (group B), respectively. Patients were observed regularly after surgeries, and the same measurements were performed. The data were assembled and entered into SPSS software (version 25, IBM Corporation, Armonk, NY, USA) and analyzed. In all analyses, a P value of less than 0.05 was considered significant. Results: Eighty-four cases with an average age of 63.97 years were evaluated. In postoperative follow-up, there were no statistically significant differences between the groups in terms of Harris hip score, SF-36, and infection (P > 0.05). However, patients who received conventional implants had more dislocation postoperatively (P = 0.045). Regarding the rehabilitation costs, there were no statistically significant differences between the groups, so the group using the conventional implants incurred a higher cost (P = 0.041). Conclusion: According to the results, both dual mobility and conventional implants had optimal functional outcomes in patients with femoral neck fractures.

The role of 18F-fluorodeoxyglucose PET/computed tomography in the diagnosis and monitoring of large vessel vasculitides - a review article.

In the last two decades, advancements in positron emission tomography (PET) technology have increased the diagnostic accuracy of patients with large-vessel vasculitis (LVV). Numerous systematic reviews and meta-analyses have been conducted, and patients suspected of having LVV can be diagnosed earlier with 18F-FDG PET. Two subtypes, giant cell arteritis (GCA) and Takayasu arteritis (TA), will progress when their response to corticosteroids and enhanced immunosuppression is inadequate. In the majority of patients, disease activity cannot be monitored solely through laboratory procedures; consequently, glucose metabolism may be a source of potential biomarkers. In this article, we discuss the current state of 18F-FDG PET/CT imaging standards.
