Winkelstabile Plattenfixation

There are fundamental biomechanical differences between fixed-angle plate systems, also referred to as internal fixators, and conventional plate-screw fixation systems. Fixed-angle systems have rapidly gained widespread acceptance in recent years for almost all indications and anatomical sites. This contribution presents tips and tricks on their implantation and on the management of complications. Much of the information has already been presented elsewhere, in print or orally. Some of it is based on the authors’ own experience in their hospitals. The tips and tricks presented here are intended to help surgeons find pragmatic solutions to intraoperative problems.     

Diagnostische videoassistierte Thorakoskopie

Modern radiologic diagnostics show a variety of pathological changes in the mediastinum, pleura, and lung but no evidence on their histogenesis. Transbronchial and transthoracal fine-needle aspiration biopsy usually cannot yield detailed diagnostic results because of its small size. Sufficient and representative material can be obtained by thoracoscopy. Video-assisted thoracoscopy allows safe and fast diagnosis of diffuse lung diseases, pleural diseases including malignant mesothelioma, indeterminate peripheral lung nodule, and mediastinal masses. This gentle diagnostic method can give invaluable information guiding further management of the thoracic injury. Video-assisted thoracoscopy is a safe and effective guiding tool if performed by experienced thoracic surgeons able to convert to thoracotomy. It is to be noted that interpretation of intraoperative findings plays a decisive role in interdisciplinary diagnostics of intrathoracal diseases.     

Cabergoline compared to levodopa in the treatment of patients with severe restless legs syndrome: results from a multi-center, randomized, active controlled trial.

We report the first large-scale double-blind, randomly assigned study to compare two active dopaminergic therapies for Restless Legs Syndrome (RLS), the dopamine agonist cabergoline (CAB) and levodopa/benserazide (levodopa). Patients with idiopathic RLS were treated with fixed daily doses of 2 or 3 mg CAB or 200 or 300 mg levodopa for 30 weeks. Efficacy was assessed by changes in the IRLS (International RLS Severity Scale) and by time to discontinuation of treatment due to loss of efficacy or augmentation. 361 of 418 screened patients (age 58 +/- 12 years, 71% females) were randomly assigned and treated (CAB: n = 178; levodopa: n = 183) in 51 centers of four European countries. Baseline IRLS total score was 25.7 +/- 6.8. The baseline-adjusted mean change from baseline to week 6 in IRLS sum score was d = -16.1 in the CAB group and d = -9.5 in the levodopa group (d = -6.6, P < 0.0001). More patients in the levodopa group (24.0%) than in the CAB group (11.9%, P = 0.0029, log-rank test) discontinued because of loss of efficacy (14.2% vs. 7.9%, P = 0.0290) or augmentation (9.8% vs. 4.0%, P = 0.0412). Adverse events (AEs) occurred in 83.1% of the CAB group and in 77.6% of the levodopa group. In both groups, most frequent AEs were gastrointestinal symptoms (CAB: 55.6%, levodopa: 30.6%, P < 0.0001). This first large-scale active controlled study in RLS showed superior efficacy of cabergoline versus levodopa after a 30-week long-term therapy. Tolerability was found more favorable with levodopa than with cabergoline.

Komplikationen nach arthroskopischer Rotatorenmanschettennaht

Rotator cuff tears are increasingly treated arthroscopically, preferentially with suture anchors since a stable anchorage in bone is possible, simple and rapid. However, the restricted view, especially with longer operating times, conceals a danger of misplacement. Such risks can be determined rapidly with experience and should be corrected as soon as possible, e.g. through a change to open procedures. In our case report, the migration of a metal anchor could be corrected in a later operation and a revision of the re-rupture was then carried out using mini-open technique.
