Rabbit model of a biofilm-contaminated, percutaneous orthopaedic endoprosthesis.

Department of Orthopaedics, Dartmouth Health, Lebanon, NH.
Preclinical models of osseointegrated orthopaedic implants tend to focus on implant stability, surface modifications to enhance integration with host tissue, and reduction in iatrogenic contamination through antibiotic-eluting/bacteria-resistant coatings. While these studies are imperative to early success in osseointegration, continued success of percutaneous devices throughout the lifespan of the patient is also critically important. A perpetual challenge to the implant is formation of bacterial biofilm on the abutment.

Emphysematous splenitis traditionally requires a splenectomy, resulting in life-long consequences for the patient. is often seen in an immunocompromised population. This case demonstrates a multidisciplinary team approach consisting of percutaneous drainage and a prolonged intravenous and oral antibiotic regime, including ceftriaxone and metronidazole, as well as amoxicillin and clavulanic acid, to provide a successful outcome in an elderly immunocompetent female.

Pyogenic spondylitis in older patients with osteoporosis presents significant challenges due to implant failure and comorbidities. This study reports two cases of osteoporotic pyogenic spondylitis with substantial bony destruction, treated with cement-augmented pedicle screws (CAPS) and titanium mesh cages (TMC). Both patients achieved complete eradication of infection, spinal stabilization, and favorable clinical outcomes without recurrence or implant failure during follow-up.

Background: Percutaneous minimally invasive retrograde screw fixation is a widely accepted treatment strategy for patients with superior ramus fractures and has shown good biomechanical stability compared to plating. Recently, elastic stable intramedullary nailing (ESIN) devices have been proposed as an alternative in the treatment of superior ramus fractures. However, biomechanical studies on this new treatment are lacking.

Unlabelled: Magerl's technique remains a widely accepted method for achieving C1-C2 fusion. Although two approaches using intermuscular corridors and biplanar X-ray guidance have been reported, there are no published studies dedicated to fully percutaneous techniques employing cannulated screws.
Objective: to demonstrate the feasibility of a fully percutaneous C1-C2 fixation technique using cannulated screws and to analyze the short- and long-term outcomes of the initial case series.
