The Stryker Exeter stem (Stryker, Kalamazoo, MI) has been in service for over 50 years and remains the most widely used cemented stem. Stem fracture is a rare complication, with recently reported rates of 1 in 10,000. We present a case of Exeter stem fracture 25 years following initial implantation as well as a large periacetabular defect secondary to osteolysis. A revision total hip arthroplasty was performed, including periacetabular bone grafting for extensive osteolysis along with retention of a stable acetabular component. This case highlights the rare complication of Exeter stem fracture as well as the technique of bone grafting a large periacetabular defect with a retained acetabular component. This is of particular interest given the rarity of this event and the resurgence in North America of cemented femoral components in total hip arthroplasty., (© 2024 The Authors.)

Introduction: The Bosworth fracture-dislocation is a rare injury originally described as an irreducible dislocation of a distal fibula fracture where the proximal fibular fragment becomes incarcerated behind the distal tibia. There have since been a few cases described of an intact distal fibula with dislocation and similar difficulties in closed reduction attempts, typically seen with associated injuries to the ankle or proximal fibula. Regardless of the specific fracture or dislocation pattern, closed reduction attempts have consistently failed in the significant majority of these cases, which can lead to complications including soft-tissue compromise, severe post-traumatic arthritis, compartment syndrome, avascular necrosis of the talus, and neurovascular compromise. There is only one case in recent literature that describes an isolated distal fibula dislocation without associated fractures or dislocations of the lower extremity; however, it required an open reduction. Cases where a closed reduction was successful to achieve an anatomic reduction of a Bosworth-type injury are exceedingly rare., Case Report: We present a rare case of a purely ligamentous, isolated distal fibula dislocation in a 21-year-old male who underwent a successful closed reduction upon initial presentation and later underwent surgical fixation with a syndesmosis repair system. We describe the technique used for a successful closed reduction for this injury and present a 1-year follow-up with excellent outcomes., Conclusion: This is the only known case report of a successful closed reduction in an isolated distal fibula dislocation, as well as demonstrating a minimally invasive technique for definitive treatment with a syndesmosis repair system. Accurate diagnosis, early treatment, and anatomic reduction are imperative for good clinical outcomes and reducing complications for Bosworth injuries. This technique may improve the rates of successful closed reductions of Bosworth injuries upon initial presentation, leading to decreased complications and improved patient outcomes., Competing Interests: Conflict of Interest: Nil, (Copyright: © Indian Orthopaedic Research Group.)

Revision total hip arthroplasty presents many challenges in regards to reconstructing or managing large amounts of bone loss and soft-tissue damage. Modern revision components, as well as techniques, have helped to address these challenges; however, the goal of any surgery is to provide the least amount of surgery with the most successful outcome. This case highlights a 74-year-old man with a Tronzo total hip arthroplasty placed over 50 years prior. He presented with subjective hip instability and radiographs demonstrating disassociation of the modular component. In an attempt to avoid more extensive and costly surgery, a custom-made all-polyethylene femoral head was used. This case illustrates the revision of likely one of the few Tronzo total hips remaining and the utility of obtaining a compassionate-use clearance from the Food and Drug Administration to create a custom piece, to minimize potential morbidity and mortality from extensive hip revision surgery., (© 2020 The Authors.)

Purpose of Review: Innovative measures have recently been proposed to prevent periprosthetic joint infection following total hip and knee arthroplasty. We sought to review these recent innovations to determine the reported reduction in periprosthetic joint infection., Recent Findings: The most recent literature demonstrates promising results in regard to hydrofiber dressings as an independent risk factor for primary prosthetic joint infection reduction, which in turn is also linked with cost savings. As our understanding of safe yet effective concentrations of antiseptic solutions develops, dilute betadine in particular has demonstrated encouraging efficacy which warrants continued investigation through controlled trials. In summary, we found that the application of a hydrofiber dressing may prove beneficial in decreasing the risk of prosthetic joint infection following primary total hip and knee arthroplasty. The gold standard for an infection prevention protocol continues to be explored and optimized.

Revision total hip arthroplasty in the setting of severe femoral bone loss can be challenging, with salvage options often limited to modular tapered stems, allograft prosthetic composites, and megaprostheses. This case highlights a 79-year-old woman with 2 years of thigh pain who is 8 years status post a revision proximal femoral allograft prosthetic composite reconstruction. Radiographs demonstrated significant stem subsidence into the femoral condyle. In an attempt to avoid a total femoral replacement and spare her functioning native knee, a tibial cone was used in conjunction with a proximal femoral replacement to structurally fill the flaring femoral canal and serve as a stable pedestal for the megaprosthesis body and provide the potential for biologic ingrowth. At 12-month follow-up, she ambulates with a cane, and radiographs reveal stable implant position.
