Osteolysis due to polyethylene wear is a well-known complication associated with total knee arthroplasty (TKA). Here, we present the case of one failure that has been rarely reported. We report the case of a 51-year-old male who fractured through a large osteolytic lesion in his femur after a previous TKA. The patient presented 4 years after revision TKA after a fall and was found to have fractured through the large lesion. After a diagnostic workup, he was treated with open reduction and internal fixation (ORIF) of the distal femur fracture, and the fixation was augmented with a morselized femoral head allograft and ViviGen (LifeNet Health, Virginia Beach, VA). Osteolysis secondary to polyethylene wear and reactions to arthroplasty components continues to be an ever-present complication of TKAs.

The best treatment method for reverse obliquity intertrochanteric fractures (ROIFs) is still under debate. Our team designed the modified proximal femoral nail (MPFN) specially for treating such fractures. The objective of this research was to introduce the MPFN device and compare the biomechanical properties with Proximal Femoral Nail Antirotation (PFNA) and InterTAN nail via finite element modelling.

Purpose: The fixation method commonly employed worldwide for treating unstable fractures of the posterior pelvic ring is the percutaneous iliosacral screw technique. However, prolonged operation time and frequent fluoroscopies result in surgical risks. This study aimed to investigate whether a new triangulation method could reduce operative and fluoroscopy times and increase the accuracy of screw placement.

Background: Proximal femoral fractures has been associated with high mortality risk, while little is known about more distal lower extremity fractures. The aim was to report 30- and 365-days mortality in surgically treated lower extremity fractures in individuals above 65 years.
Materials And Methods: We extracted data from the Danish National Patient Register on all surgically treated lower extremity fracture in the period 1998-2017.

Background: Malnutrition predicts poor outcomes following hip fracture, affecting patient recovery, healthcare performance, and costs. Evidence-based guidelines recommend multicomponent, interdisciplinary nutrition care to improve intake, reduce complications, and enhance outcomes. This study examines global variation in oral nutrition support for older (65+ years) hip fracture inpatients.

Background: Osteoporosis is characterized by the microstructural depletion of bone tissue and decreased bone density, leading to an increased risk of fractures. Nakai, an endemic species of the Korean Peninsula, grows wild in Ulleungdo. In this study, we aimed to investigate the effects of and its components on osteoporosis.
