Management of periprosthetic knee joint infections: focus on the role of Nuclear Medicine (v2).

Background: When faced with a painful knee replacement, ruling out infection is mandatory to set the correct therapeutic approach. However, it is not always easy, especially in subclinical/chronic infections. A multidisciplinary approach is necessary to assess in the most correct way each case of suspected periprosthetic knee joint infection.

Combined Microwave Ablation and Osteosynthesis for Long Bone Metastases.

The purpose of this study was to evaluate the feasibility, safety and efficacy of microwave ablation (MWA) in combination with open surgery nail positioning for the treatment of fractures or impending fractures of long bone metastases. Eleven patients (four men, seven women) with painful bone metastases of the humerus, femur or tibia with non-displaced fractures (one case) or impending fractures (10 cases) underwent open MWA in combination with osteosynthesis by locked nail positioning. Pain intensity was measured using a VAS score before and after treatment.

Late onset periprosthetic joint infection of the knee caused by Streptococcus anginosus. Case presentation and literature review.

Periprosthetic joint infection (PJI) is one of the most dramatic complications of joint arthroplasty. Although streptococcal bone and joint infections are less common than staphylococcal cases, their role as causative agents of bone and joint remains significant accounting for at least 10% of PJIs. Streptococcus anginosus group (SAG) bacteria are usually found in the normal flora of the urogenital tract, intestinal tract and oropharynx and could cause pyogenic infections to affect brain, lungs and liver.

Poller blocking screw augmentation to treat delayed union of proximal tibial shaft fracture after locked IM nailing.

Cases: We present the cases of two adult male patients with painfully delayed union of proximal tibia diaphyseal fracture after intramedullary nailing. Patients underwent to nail dynamization and Poller blocking screw augmentation at 3 and 5 month, respectively, after the index surgery. Both patients were pain-free after the surgery and bone-union were radiographically evident after 3 months.

The Epidemiology of Fractures and Muskulo-Skeletal Traumas During COVID-19 Lockdown: A Detailed Survey of 17.591 Patients in a Wide Italian Metropolitan Area.

Introduction: On 9 March 2020 the Italian Government declared a national lockdown to curb the spread of Covid-19. The aim of our study was to analyze the effects of such intervention on the traumatological emergency service, with particular emphasis on variations in trauma incidence and patients' characteristics.

Materials And Methods: An observational analysis was performed.

Conservative treatment of early-onset tubercular periprosthetic joint infection following total knee arthroplasty.

Tubercular periprosthetic joint infections (PJI) are uncommon diseases in developed countries. Therefore, the systematic screening for Mycobacterium tuberculosis (TB) is not currently recommended before a total knee arthroplasty procedure. However, due to the new human migration flows and higher mycobacterial infection rates, tuberculosis could represent a rare but potential cause for PJI.
