Background: Gravid females with pelvic fractures are rarely encountered by the orthopaedic trauma surgeon. The initial injury can be detrimental to the pregnant patient, but an unnecessary "second hit" from surgery could also contribute to the outcome of the fetus. Understanding the surgical risks for this unique patient population requires knowledge about the negative effects of anesthesia, surgical exposures, and radiation.

Sandwiched Strut Allografts with Stem Retention to Treat Fragile Periprosthetic Femoral Fractures: A Case Report.

Managing periprosthetic femoral fractures is challenging, particularly in osteoporotic patients with fragile bones. Revision with a long stem is commonly considered but may fail to provide adequate fixation and stability in fragile bones. A novel approach using sandwiched strut allografts and controlled bone crushing with robust cable fixation can offer mechanical support and provide secondary stability to the loosened femoral stem and can be considered a treatment option for low-demand patients.

The study aimed to evaluate a newly designed semicircular implant for the fixation of Vancouver Type B1 periprosthetic femoral fractures (PFFs) in total hip arthroplasty (THA) patients. To determine its strength and clinical applicability, the new implant was compared biomechanically with conventional fixation methods, such as lateral locking plate fixation and a plate combined with cerclage wires. : Fifteen synthetic femur models were used in this biomechanical study.

Background: Cementless hip hemiarthroplasty is one of the options for the treatment of osteoporotic femoral neck fractures. Intraoperative periprosthetic femoral calcar fractures sometimes occur during the surgery, and the use of cerclage wiring to maintain the position and stability of the femoral stem and prevent the progression of the fracture. This study examines the outcomes of cerclage wiring to treat intraoperative periprosthetic calcar fractures in cementless hip hemiarthroplasty in osteoporotic femoral neck fractures.
