Midterm results of stemless impaction shoulder arthroplasty for primary osteoarthritis: a prospective, multicenter study.

Background: Stemless shoulder arthroplasty using 4 open-fin press-fit anchors has been showing promising short-term clinical and radiographic results for patients' primary osteoarthritis. This prospective, multicenter study presents 5-year postoperative clinical and radiological outcomes of a stemless shoulder arthroplasty for primary osteoarthritis.

Methods: Between November 2012 and December 2015, 100 patients were treated for primary osteoarthritis with the Sidus stem-free shoulder system at 7 European centers.

Sidus Stem-Free Shoulder System for primary osteoarthritis: short-term results of a multicenter study.

Background: The aim of this prospective multicenter study was to evaluate clinical and radiologic results of a new metaphyseal anchored system. This system features a different anchor geometry that potentially leads to better bony integration and less loosening.

Methods: From November 2012 until December 2015, 148 patients (151 shoulders) were treated with the Sidus Stem-Free Shoulder System at 9 centers in Europe.

A multicenter study to evaluate subscapularis muscle function using 5:30 o'clock portal for antero-inferior shoulder stabilization.

Introduction: The purpose of this study was to compare the outcome after arthroscopic antero-inferior shoulder stabilization with and without using a 5:30 o'clock portal.

Materials And Methods: Sixty-two patients [age (mean ± SD), 28.05 ± 8.

Significant benefit for older patients after arthroscopic subacromial decompression: a long-term follow-up study.

Background: Patients suffering from isolated subacromial impingement (SI) of their shoulder but who are resistant to other therapies benefit substantially from arthroscopic subacromial decompression (ASD) if they are young (<60 years). Although physical demands rise notably in the older population, it still remains unclear if surgery leads to better results in these patients. Therefore, the aim of this study was to focus on the impact of age on the functional outcome in elderly patients suffering from SI.

The Munich Shoulder Questionnaire (MSQ): development and validation of an effective patient-reported tool for outcome measurement and patient safety in shoulder surgery.

Background: Outcome measurement in shoulder surgery is essential to evaluate the patient safety and treatment efficiency. Currently this is jeopardized by the fact that most patient-reported self-assessment instruments are not comparable. Hence, the aim was to develop a reliable self-assessment questionnaire which allows an easy follow-up of patients.

The fulcrum axis: a new method for determining glenoid version.

Previously applied methods for the evaluation of glenoid version did not use body-surface landmarks; therefore, it is not possible to get information about glenoid version from the outside. The tip of the coracoid and the posterolateral corner of the acromion can easily be found on the body surface. These 2 landmarks were connected by a line called the fulcrum axis.

Functional malcentering of the humeral head and asymmetric long-term stress on the glenoid: potential reasons for glenoid loosening in total shoulder arthroplasty.

We tested the hypothesis that functional malcentering of the humeral head during arm elevation exists in patients with glenohumeral osteoarthritis and influences long-term glenoid loading. Twenty-eight healthy volunteers and 10 patients with primary osteoarthritis, 10 with cuff-arthropathy, and 1 with dysplastic glenoid were examined. Open magnetic resonance imaging and 3-dimensional (3D) digital postprocessing techniques were applied in various arm positions.

Hemiarthroplasty for Humeral Head Fractures.

Objective: Replacement of the fractured humeral head with a modular prosthesis. The procedure aims at an adequate reconstruction of shape and function of the shoulder.

Indications: Displaced three- and four-part fractures of the proximal humerus that cannot be reduced and internally fixed.

Serum S-100B and interleukin-8 as predictive markers for comparative neurologic outcome analysis of patients after cardiac arrest and severe traumatic brain injury.

Objective: To compare S-100B and interleukin-8 serum values on scene/at admission and 12 hrs later with respect to neurologic long-term outcome 12 months after cardiac arrest and return of spontaneous circulation, as well as after severe traumatic brain injury.

Design: Prospective comparative cohort study.

Setting: On scene; intensive care units of a university hospital.
