Locking plate (LP) re-fixation is mainly used to treat postoperative implant periprosthetic refractures; however, the extensive trauma and the fixation form of LP make the operation difficult. The bridge combined fixation system (BCFS) is a new clip-rod internal fixation system, and its clinical application is in its infancy. To compare the clinical effect of BCFS and LP in the treatment of geriatric postoperative implant periprosthetic refracture following proximal femoral fracture surgery. Thirty-two patients (14 with BCFS and 18 with LP) with postoperative implant periprosthetic refracture following proximal femoral fracture surgery, who underwent surgery in our hospital, were analyzed retrospectively. The incision length, operation time, intraoperative bleeding volume, postoperative drainage volume, postoperative hospital stay, fracture healing time and complications of each patient were recorded. Regular radiographs were taken after the operation to evaluate the fracture reduction and fixation. All the patients were followed for 12 months to evaluate their limb function by Johner-Wruhs scoring criteria. The patients were followed for an average of 24.1 months, and all achieved bony union, with no complications such as infection, nonunion, and internal fixation instrument falling off and loosening after the operation. Delayed healing occurred in two cases in the LP group. The average value of surgical incision length, operation time, postoperative hospitalization time and fracture healing time in the BCFS group were significantly smaller than those in the LP group, accompanied by a decrease in intraoperative bleeding and postoperative drainage volumes (P < .05). The rate of limb function in the BCFS group (85.7%) was higher than that in the LP group (83.3%), with no significance (P > .05). The BCFS in the refracture around the implant of the proximal femoral fracture exhibited many advantages such as simple operation, strong plasticity, effective reduction of surgical trauma, promotion of fracture healing and early functional rehabilitation, etc, making it an advantageous clinical application.

Aims: The Peri-Implant and PeriProsthetic Survival AnalysiS (PIPPAS) study aimed to investigate the risk factors for one-year mortality of femoral peri-implant fractures (FPIFs).
Methods: This prospective, multicentre, observational study involved 440 FPIF patients with a minimum one-year follow-up. Data on demographics, clinical features, fracture characteristics, management, and mortality rates were collected and analyzed using both univariate and multivariate analyses.

Introduction: This paper examines the use of local antibiotic therapy in one-stage septic revision surgery for late periprosthetic joint infections (PJIs). This case study suggests that morselized bone allografts impregnated with antibiotics in powder form are a preferable alternative to polymethyl methacrylate (PMMA) because they can generate higher local antibiotic concentrations. Current research also recommends using vancomycin and aminoglycosides as the preferred choice of antibiotics, as they may have low diffusion in tissues when administered intravenously, but are effective when administered locally.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

Objective: Transcutaneous osseointegration prosthetic systems (TOPS) offer a stable skeletal attachment for artificial limbs post-extremity amputation, serving as an alternative to socket attachment. Press-fit osseointegration implants (OI) utilized in TOPS consistently enhance quality of life and mobility for amputees, particularly those experiencing socket-related issues. Despite notable benefits, late complications such as infection and implant loosening pose challenges unique to TOPS due to their percutaneous nature.
