Intraoperative Doppler flowmetry evaluation of humeral head perfusion after proximal humerus fracture.

Background: Understanding vascularity and assessing the risk of post-traumatic avascular necrosis are crucial for predicting outcomes and identifying optimal treatment options in proximal humerus fractures (PHFs). Until now, Hertel et al have been the only researchers to evaluate the intraoperative perfusion of the humeral head after fracture using Doppler flowmetry in a central single drill hole within the head. This pilot study aims to standardize the evaluation of intraoperative perfusion measurements in different areas of the humeral head in patients with PHF.

Dysregulation of Wnt signaling in bone of type 2 diabetes mellitus and diabetic Charcot arthropathy.

Background: Type 2 diabetes mellitus (T2DM) patients show a markedly higher fracture risk and impaired fracture healing when compared to non-diabetic patients. However in contrast to type 1 diabetes mellitus, bone mineral density in T2DM is known to be normal or even regionally elevated, also known as diabetic bone disease. Charcot arthropathy is a severe and challenging complication leading to bone destruction and mutilating bone deformities.

Current management of trimalleolar ankle fractures.

A trimalleolar ankle fracture is considered unstable and treatment is generally performed operatively. Computed tomography is important for the operative planning by providing an elaborated view of the posterior malleolus.Trimalleolar ankle fractures have a rising incidence in the last decade with up to 40 per 100,000 people per year.

The role of serum C-reactive protein in the diagnosis of periprosthetic shoulder infection.

Introduction: There is a paucity of literature regarding serum C-reactive protein (CRP) in the evaluation of a shoulder periprosthetic joint infection (PJI). The purpose of the current study was to establish cutoff values for diagnosing shoulder PJI and evaluate the influence of the type of infecting microorganism and the classification subgroups according to last proposed International Consensus Meeting (ICM) criteria on the CRP level.

Materials And Methods: A retrospective analysis of all 136 patients, who underwent septic or aseptic revision shoulder arthroplasty in our institution between January 2010 and December 2019, was performed.

[Delayed occurrence of compartment syndrome of the upper arm after shovelling snow by a patient under oral anticoagulation].

This article reports the case of an 81-year-old male patient under treatment with oral anticoagulation who suffered delayed compartment syndrome of the upper arm from arterial capillary hemorrhage after shovelling snow. The diagnosis was made 48 h after the initial symptoms in the emergency surgical department of the Klinikum rechts der Isar (München) with the presence of clear neurological deficits. Following computed tomography angiography (CTA) imaging an emergency dermatofasciotomy was carried out as well as a vascular ligature via a medial approach.

Emergency room as primary point of access in the German healthcare system : Objective evaluation and interview of motivation for ER entrance of 235 ER patients in a German hospital.

Background: The importance of emergency rooms (ERs) as everyday healthcare suppliers is growing. Due to increasing patient flows, hospitals are forced to raise physicians' and caregivers' headcount continuously to meet the new demand of patients seeing the ER as primary point of contact in non-emergency situations. Patients from various cultural and educational backgrounds approach the ER for different reasons.

The Munich Ankle Questionnaire (MAQ): a self-assessment tool for a comprehensive evaluation of ankle disorders.

Background: There are many approved patient-related outcome measurement tools regarding ankle pathologies. However, there is none incorporating the range of motion (ROM) as an objective parameter. Most instruments focus on subjective parameters such as pain and impairment at work or daily living.

Hyperinsulinemia reduces osteoblast activity in vitro via upregulation of TGF-β.

Affecting more than 230,000,000 patients, diabetes mellitus is one of the most frequent metabolic disorders in developed countries. Among other complications, diabetic patients have an increased fracture risk and show delayed fracture healing. During the disease progression, these patients' blood glucose and insulin levels vary significantly.

The Munich Myocardial Infarction Registry: impact of C-reactive protein and kidney function on hospital mortality in diabetic patients.

Introduction: The aim of this study was to analyse hospital mortality with regards to the presence of diabetes, elevation of C-reactive protein (CRP) levels and impaired kidney function (IKF) on admission.

Methods: All patients in the Munich Myocardial Infarction Registry (1999-2004, n = 2,015) were assessed. In both the diabetic (n = 770, 38%) and non-diabetic (n = 1,245, 61.
