Treatment of an Infected Tibial Shaft Non-Union Using a Novel 3D-Printed Titanium Mesh Cage: A Case Report.

Treating large bone defects resulting from trauma, tumors, or infection can be challenging, as current methods such as external fixation with bone transport, bone grafting, or amputation often come with high costs, high failure rates, high requirements for follow-up, and potential complications. In this case report, we present the successful treatment of a complicated, infected tibial shaft non-union by using a personalized three-dimensional (3D)-printed titanium mesh cage. This case adds to the existing body of literature by demonstrating successful integration of bone into a titanium implant and a demonstration of immediate postoperative weight bearing in the setting of suboptimal operative and psychosocial conditions.

Increased morbidity and mortality in elderly patients with lower extremity trauma and associated injuries: A review of 420,066 patients from the national trauma database.

Introduction: There is a paucity of research addressing the morbidity and mortality associated with polytrauma in elderly patients. This study aimed to compare the outcomes of elderly trauma patients with an isolated lower extremity fracture, to patients lower extremity fractures and associated musculoskeletal injuries.

Methods: This study is a retrospective review from the National Trauma Database (NTDB) between 2008 and 2014.

Treatment of a complex orthopaedic infection due to extensively drug-resistant .

According to the Centers for Disease Control and Prevention (CDC), approximately 51 000 healthcare-associated infections caused by occur annually in the USA, more than 6000 of which (13%) are caused by multidrug resistant (MDR) strains. Ceftolozane/tazobactam (TOL/TAZ) (Zerbaxa) was approved by the US Food and Drug Administration (FDA) in December 2014 for the treatment of complicated intra-abdominal and urinary tract infections. At this time, clinical data on the role of TOL/TAZ treatment outside of FDA-approved indications is limited.

Molybdenum scavenging by iron monosulfide.

Molybdenum profiles in dated sediment cores provide useful historical information about anoxia in anthropogenically impacted natural waters but would be of greater service if Mo fixation mechanisms were better understood. Here, we explore Mo scavenging by precipitated FeS in a model system consisting of an FeIII-bearing kaolinite (KGa-1B) dispersed in NaHS solutions. Test solutions contain 18 microM thiomolybdates (mainly MoOS3(2-)).
