Indian Ocean glacial deoxygenation and respired carbon accumulation during mid-late Quaternary ice ages.

Reconstructions of ocean oxygenation are critical for understanding the role of respired carbon storage in regulating atmospheric CO. Independent sediment redox proxies are essential to assess such reconstructions. Here, we present a long magnetofossil record from the eastern Indian Ocean in which we observe coeval magnetic hardening and enrichment of larger, more elongated, and less oxidized magnetofossils during glacials compared to interglacials over the last ~900 ka.

Convalescence after arthroscopic capsular release in frozen shoulder.

Introduction: To determine if arthroscopic capsular release (ACR) shortens duration of illness in frozen shoulder (FS) in comparison to the depicted natural course of 30.1 months and to identify risk factors for persisting complaints.

Materials And Methods: A consecutive group of 71 shoulders in 70 patients with mean age of 54 (37-74) years with FS were treated by ACR and enrolled in our study with follow-up investigation at 1, 3, 6 and finally 32 (19-49) months postoperatively.

Calcifying tendinitis and outlet impingement - Evaluation of the prevalence analyzing radiological and intraoperative criteria.

Introduction: The question of our study was to evaluate the incidence of coexisting outlet impingement among patients with calcifying tendinitis and a failure of the conservative treatment using intraoperative in addition to radiological criteria.This question is of clinical relevance as there is still a discussion about whether an additional arthroscopic subacromial decompression (ASD) should be performed when arthroscopic removal of the calcific deposits is needed.

Materials And Methods: From February 2017 to 02/2018, we prospectively enrolled 50 patients who needed shoulder arthroscopy for calcifying tendinitis.

Coupled microbial bloom and oxygenation decline recorded by magnetofossils during the Palaeocene-Eocene Thermal Maximum.

Understanding marine environmental change and associated biological turnover across the Palaeocene-Eocene Thermal Maximum (PETM; ~56 Ma)-the most pronounced Cenozoic short-term global warming event-is important because of the potential role of the ocean in atmospheric CO drawdown, yet proxies for tracing marine productivity and oxygenation across the PETM are limited and results remain controversial. Here we show that a high-resolution record of South Atlantic Ocean bottom water oxygenation can be extracted from exceptionally preserved magnetofossils-the bioinorganic magnetite nanocrystals produced by magnetotactic bacteria (MTB) using a new multiscale environmental magnetic approach. Our results suggest that a transient MTB bloom occurred due to increased nutrient supply.

Ultrasound is as reliable as plain radiographs in the diagnosis of cam-type femoroacetabular impingement.

Introduction: In the diagnosis of femoroacetabular impingement (FAI), plain radiographs are accepted as the initial imaging method. However, there is no consensus regarding the optimal lateral view, and radiographs can underestimate the asphericity of the head-neck junction. Our research question was if ultrasound has at least the same reliability as X-ray and can be used as an alternative or additional method in the initial imaging of FAI.

Patients With Impingement Syndrome With and Without Rotator Cuff Tears Do Well 20 Years After Arthroscopic Subacromial Decompression.

Purpose: To present the long-term outcome of arthroscopic subacromial decompression (ASD) for patients with impingement syndrome with or without rotator cuff tears as well as with or without calcific tendinitis in a follow-up of 20 years.

Methods: We included 95 patients after a mean follow-up of 19.9 (19.

Ultrasonography can quantify the extent of osteochondroplasty after treatment of Cam-type femoroacetabular impingement.

Purpose: Surgical resection of femoroacetabular Cam impingement (cam-FAI) is now a generally accepted treatment, producing adequate hip score increases. Insufficient resection at the head-neck junction is the main reason for revision. The anterolateral region of the head-neck junction is visualized only suboptimally by radiography, which can be inadequate for monitoring resection results postoperatively.

Biomechanical analysis for primary stability of shoulder arthrodesis in different resection situations.

Background: Only very few publications dealing with shoulder arthrodesis after bone resection procedures and no biomechanical studies are available. The presented biomechanical analysis should ascertain the type of arthrodesis with the highest primary stability in different bone loss situations.

Methods: On 24 fresh cadaveric shoulder specimens three different bone loss situations were investigated under the stress of abduction, adduction, anteversion and retroversion without destruction by the use of a material testing machine.

Evaluation of Cam-type femoroacetabular impingement by ultrasound.

Purpose: In the diagnosis of femoroacetabular impingement (FAI), magnetic resonance imaging (MRI) and X-ray are widely accepted methods for detection. When evaluating the hip head-neck junction using MRI, oblique axial sequences are required. However, the construction and analysis of these images are restricted to specialist radiologists and surgeons in the field of hip joint MRI.

[Replacement of the Glenoid Using a Reconstruction Socket (EPOCA RECO].

Objective: Alleviation of pain, restoration of function and active range of motion in the shoulder in case of cuff tear arthropathy.

Indications: Cuff tear arthropathy with an insufficient coracoacromial arch and salvage operation of failed hemiprosthesis or reverse shoulder prosthesis.

Contraindications: Active or chronic infections.
