Managing Calciphylaxis: Insights from Real-World Cases at a Tertiary Academic Center.

Calciphylaxis is a rare and potentially fatal condition involving chronic, nonhealing wounds caused by microvascular calcification. There is currently no approved treatment for calciphylaxis, contributing to its devastating impacts on quality of life. In this case series, the authors highlight instances of potentially misdiagnosed calciphylaxis in a cohort of patients and emphasize the importance of accurate diagnosis through multidisciplinary management approaches.

Developing a Risk Score for Predicting Multiple Revision Surgeries in Patients With Fracture-Related Infections.

Introduction: Postoperative infections are a leading cause of morbidity following fracture repair. The purpose of this study is to develop a risk score predicting fracture-related infection (FRI) that will require one versus multiple revision surgeries related to infection eradication and bone healing.

Methods: This is a retrospective cohort study conducted at a single level I trauma center from 2013 to 2020.

The purpose of this study is to identify risk factors associated with dysfunctional elbow stiffness in distal humerus fractures after operative fixation.

Methods: A retrospective review of all distal humerus fractures that underwent operative fixation (AO/OTA 13A-C) at a single level 1 trauma center from November 2014 to October 2021.

Structured bubbling in vibrated gas-fluidized beds of binary granular particles: experiments and simulations.

Mixing and segregation of granular particles on the basis of size and density from vertical vibration or upward gas flow is critical to a wide range of industrial, agricultural and natural processes. Recently, combined vibration and gas flow under certain conditions has been shown to create periodically repeating structured bubbling patterns within a fluidized bed of spherical, monodisperse particles. Here, we demonstrate with experiments and simulations that structured bubbling can form in binary mixtures of particles with different size and density, but with similar minimum fluidization velocities.

The Effect of Extracorporeal Membrane Oxygenation in Patients With Multiple Orthopaedic Injuries.

Introduction: Extracorporeal membrane oxygenation (ECMO) plays a vital role in providing life support for patients with reversible cardiac or respiratory failure. Given the high rate of complications and difficulties associated with caring for ECMO patients, the goal of this study was to compare outcomes of orthopaedic surgery in polytrauma patients who received ECMO with similar patients who have not. This will help elucidate the timing and type of fixation that should be considered in patients on ECMO.

Setting: Eight centers.

Outcomes of SARS-CoV-2 infection among patients with orthopaedic fracture surgery in the National COVID Cohort Collaborative (N3C).

Background: The objective of this study was to investigate the outcomes of COVID-19-positive patients undergoing orthopaedic fracture surgery using data from a national database of U.S. adults with a COVID-19 test for SARS-CoV-2.

Nail Plate Constructs are Associated with Decreased Rates of Reoperation in Complex Distal Femur Fractures.

Objectives: To determine if nail plate constructs have lower rates of reoperation to promote bone healing than lateral locking plates in the treatment of distal femur fractures.

Design: Retrospective Cohort.

Setting: Single Level 1 trauma centerPatients/Participants: 312 consecutive patients treated operatively for native distal femur fractures (OTA/AO 33A or 33C).

Does pes anserinus tenotomy affect surgical site infection rate in operative tibial plateau fractures?

Purpose: To assess if pes anserinus tenotomy (PAT) during definitive open reduction and internal fixation (ORIF) of tibial plateau fractures is associated with a decreased risk of surgical site infection (SSI) and other postoperative complications.

Methods: A retrospective review of all adults who underwent ORIF for tibial plateau fractures from April 2005 to February 2022 at single level 1 trauma center was performed. Patients who had a medial approach to the plateau with minimum three-month follow-up were required for inclusion.

Setting: Six Level I trauma centers.

Management of open pelvic ring injuries.

Open pelvic ring injuries are rare clinical entities that require multidisciplinary care. Due to the scarcity of this injury, there is no well-defined treatment algorithm. As a result, conflicting evidence surrounding various aspects of care including wound management and fecal diversion remain.

Stomal and peristomal complications management: a retrospective study.

Objective: Correctly identifying and managing stomal and peristomal complications are key to assisting individuals with an ostomy when they are facing challenges with self-care. Providers that are knowledgeable and experienced with stomal and peristomal care are vital when complications arise. Providing care that is consistent with findings in current high evidence-based literature supports the goal of providing optimal patient outcomes in a timely manner.

Bicondylar tibial plateau fracture dislocations with an intact anterolateral cortical rim: A surgical technique.

A displaced medial tibial plateau fracture with central and lateral impaction, but an intact anterolateral cortical rim, is an uncommon variant of bicondylar tibial plateau fracture that presents a number of challenges. Without a lateral metaphyseal fracture line to work through, it is challenging to address central and lateral impaction. Previously published techniques for addressing this fracture pattern describe an intra-articular osteotomy of the lateral plateau to aid visualization and reduction, or use a posterolateral approach to the proximal tibia with or without an osteotomy of the proximal fibula.
