Successful Outcomes With Nonoperative Treatment and Immediate Weightbearing Despite Stress-Positive Radiographs in Isolated Distal Fibula (OTA/AO 44B) Fractures.

Objectives: To determine whether a nonoperative management protocol results in equivalent outcomes in isolated OTA/AO 44B (Weber B) fractures without initial medial clear space (MCS) widening regardless of stress radiography findings.

Design: Prospective cohort.

Setting: Level 1 academic trauma center.

Adherence to Antibiotic Recommendations and Infection Among Patients With Open Long-Bone Fractures: An Examination of Antibiotic Prioritization in Fracture Management.

Open fractures are at high risk of infection because of exposure of bone and tissue to the environment. Initiation of intravenous antibiotics is recommended within 1 hour of hospital arrival, although the presence of other severe injuries may lead to delays in fracture management. This retrospective study of adult patients with open long-bone fractures admitted to six level 1 trauma centers between January 1, 2018, and December 31, 2019, aimed to examine adherence to antibiotic recommendations.

Temporizing External Fixation vs Splinting Following Ankle Fracture Dislocation.

Background: Closed reduction and splinting followed by outpatient management is standard of care for temporizing most ankle fractures. However, ankle fracture-dislocation potentially warrants a different approach based on the propensity for loss of reduction. The purpose of this study was to determine the rate of complications associated with closed reduction and splinting of unstable ankle fracture-dislocations.

Is It Safe to Prep the External Fixator In Situ During Second-Stage Pilon Surgical Treatment?

Objective: To evaluate the infection rate of our protocol of prepping the external fixator in situ during definitive second-stage pilon fracture open reduction internal fixation.

Design: Retrospective clinical investigation.

Setting: Academic Level 1 Trauma Center.

Initial Experience With Percutaneous IM Rodding of the Humeri in Children With Osteogenesis Imperfecta.

Background: To report a single-center surgical experience treating humeral deformity and fractures in children with osteogenesis imperfecta (OI) using the Fassier-Duval (FD) intramedullary elongating rods.

Methods: A retrospective review was conducted between December 2005 and July 2013 of all OI patients who underwent FD rodding with a minimum of 1-year follow-up. All patients were also being concurrently treated with bisphosphonates.

Outcomes of Aortic Surgery for Abdominal Aortic Graft Infections.

Background: Literature on postoperative outcomes following aortic surgery for aortic graft infection (AGI) is limited by relatively small sample sizes, resulting in lack of national benchmarks for quality of care. We report in-hospital outcomes following abdominal aortic surgery for AGI and identify factors associated with postoperative complications using the Nationwide Inpatient Sample (NIS) database.

Methods: Patients who underwent aortic graft resection for AGI were identified from the 2002 to 2008 NIS database, a multicenter database capturing 20% of all US admissions.

Theoretical study of Cl(-)RG (rare gas) complexes and transport of Cl- through RG (RG = He-Rn).

We present a systematic investigation of the accuracy of the various theories and basis sets that can be applied to study the interaction of Cl(-) ions with Ar atoms. It is conclusively shown that gaseous ion mobility can distinguish among theoretical ion-neutral interaction potentials. Based on the conclusions, high-level ab initio potential energy curves are obtained for all of the Cl(-)-RG (RG = He-Rn) complexes.
