The VIDIA BONE score as a patient- and fracture-related risk score for the occurrence of fracture sequelae in proximal humerus fractures.

Purpose: The aim of the study was to determine preoperative patient- and fracture-related risk factors for estimating the risk of fracture sequelae after surgically treated proximal humerus fractures (PHF) using locking plate osteosynthesis. The purpose was to develop a fracture sequelae risk score as an additional tool to facilitate the treatment strategy for PHF.

Methods: All patients with PHF who underwent surgery with locking plate osteosynthesis were included.

All-Endoscopic Treatment of Acute Acromioclavicular Joint Dislocation: Coracoclavicular Double Cerclage EndoButton Technique and Acromioclavicular Stabilization Using the Coracoacromial Ligament.

High-grade the acromioclavicular joint (ACJ) dislocations can be treated surgically. Endoscopic techniques to stabilize the ACJ using an EndoButton suture technique for coracoclavicular (CC) fixation have been shown to be safe and reproducible. Several studies have demonstrated the benefit of stabilizing the ACJ to reduce postoperative horizontal instability.

Postoperative Fluid Accumulation is Associated With Underestimation of AKI Severity in Lung Transplant Recipients.

Background: Post-lung transplantation (LTx) fluid accumulation can lead to dilution of serum creatinine (SCr). We hypothesized that fluid accumulation might impact the diagnosis, staging, and outcome of posttransplant acute kidney injury (AKI).

Methods: In this retrospective study, we analyzed data from 131 adult LTx patients at a single German lung center between 2005 and 2018.

Comparative study of two different horizontal stabilisation methods in arthroscopically assisted coracoclavicular stabilisation for acute acromioclavicular joint dislocations-Good clinical outcome and no correlation to recurrent anteroposterior instability.

Purpose: The hypothesis of this study was that acromioclavicular K-wire transfixation is noninferior to horizontal FiberTape cerclage in terms of vertical and horizontal stability in the short follow-up period of acute acromioclavicular joint (ACJ) dislocations fixed with an arthroscopically assisted coracoclavicular single bundle endobutton cerclage system. The secondary aim was to investigate the impact of postoperative recurrent instability on clinical outcomes in these populations.

Methods: In this consecutive clinical trial, all patients who underwent surgery for acute AC joint dislocation between January 2017 and December 2021 were included.

Correct positioning of the calcar screw leads to superior results in proximal humerus fractures treated with carbon-fibre-reinforced polyetheretherketone plate osteosynthesis with polyaxial locking screws.

Background: Plate osteosynthesis with implants made of carbon-fibre-reinforced polyetheretherketone (CFR-PEEK) has recently been introduced for the treatment of fractures of the proximal humerus (PHFs). The advantages of the CFR-PEEK plate are considered to be its radiolucency, its favourable modulus of elasticity, and the polyaxial placement of the screws with high variability of the angle. The primary aim of this study is to investigate the influence of calcar screw positioning on the complication and revision rates after CFR-PEEK plating of PHFs.

Surgical treatment of fracture sequelae of the proximal humerus according to a pathology-based modification of the Boileau classification results in improved clinical outcome after shoulder arthroplasty.

Background: Fracture sequelae of the proximal humerus were classified by Boileau into four types. Since there are pathomorphological differences and specific characteristics within the four types, we have developed a subclassification. For elderly patients, shoulder arthroplasty is mostly recommended.

Functional results and unfavorable events after treatment of proximal humerus fractures using a new locking plate system.

Background: Proximal humerus fractures are often treated with a fixed-angle titanium plate osteosynthesis. Recently, plates made of alternative materials such as carbon fibre-reinforced polyetheretherketone (CFR-PEEK) have been introduced. This study presents the postoperative results of patients treated with a CFR-PEEK plate.

Severe Heterotopic Ossification with Proximal Entrapment of the Ulnar Nerve following Primary Anterior Shoulder Dislocation.

Heterotopic ossifications (HO) in the shoulder are rare. The effectiveness of conservative treatment is limited, and therefore, symptomatic cases are usually treated surgically. However, there are no guidelines for the surgical treatment of HO.

Proximal humeral fracture morphology in patients with advanced cuff tear arthropathy: an observational study in a surgically treated cohort.

Background: In the presence of cuff tear arthropathy (CTA), joint kinematics is alternated and fracture configuration might be different. The purpose of this study was to identify fracture patterns in patients with advanced CTA to facilitate recognition and treatment.

Methods: Radiographs and computed tomography scans of all patients undergoing surgical treatment for a proximal humeral fracture (PHF) in our institution during a 5-year period were retrospectively analyzed.

Tuberosity healing improves functional outcome following primary reverse shoulder arthroplasty for proximal humeral fractures with a 135° prosthesis.

Introduction: Reverse shoulder arthroplasty (RSA) is a common treatment for proximal humeral fractures (PHFs) in the elderly. This study evaluates the influence of tuberosity healing (TH) on functional outcome following a 135° humeral inclination RSA for PHFs.

Methods: Retrospectively, all patients with an acute PHF treated with a 135° humeral inclination RSA at four centers during a three-year period were followed up.

Evaluating the Use of Circulating MicroRNA Profiles for Lung Cancer Detection in Symptomatic Patients.

Importance: The overall low survival rate of patients with lung cancer calls for improved detection tools to enable better treatment options and improved patient outcomes. Multivariable molecular signatures, such as blood-borne microRNA (miRNA) signatures, may have high rates of sensitivity and specificity but require additional studies with large cohorts and standardized measurements to confirm the generalizability of miRNA signatures.

Objective: To investigate the use of blood-borne miRNAs as potential circulating markers for detecting lung cancer in an extended cohort of symptomatic patients and control participants.

Transcatheter aortic valve implantation in severe calcified annulus using the Lotus valve system: Increased incidence of fatal major vascular complications.

Objectives: This study reports the outcome of a highly selected transcatheter aortic valve implantation (TAVI) population.

Background: In patients with aortic valve stenosis and severe calcification of the left ventricular outflow tract and/or the annulus, the Boston Scientific Lotus valve provided a low paravalvular leakage rate omitting the risk of annular rupture.

Methods: Until now more than 3,600 TAVI procedures were performed at our institution.
