Easy and safe: a new surgical fixation technique for acute and chronic anterior instabilities of the sternoclavicular joint: technique and results.

Background: Instabilities of the sternoclavicular (SC) joint are a rare injury, accounting for only 3% of all injuries of the shoulder girdle. Although acute posterior dislocations are an emergency and require immediate surgical intervention, anterior instabilities (first and second degree according to Allman) can mostly be treated conservatively. Chronic and highly instable acute anterior instabilities often impose a significant limitation on the lives of affected patients.

Tuberosity refixation improves functional outcome following primary reverse shoulder arthroplasty in proximal humeral fracture.

Introduction: The purpose of this prospective study was to examine clinical results of tuberosity refixation in RSA for the treatment of displaced PHF in elderly patients. We hypothesized that tuberosity refixation would increase clinical outcome.

Methods: In this prospective study, 50 patients were included after receive a primary RSA for complex proximal humeral fracture between March 2013 and December 2015 for follow-up after three, 12 and 24 months.

[Management of muscle trauma in popular sports].

Muscle injuries make up the majority of injuries in popular sports. The causes for the development are multifactorial and can be divided into functional disorders and a lack of knowledge regarding training control. Insufficient warm-up and overtraining both increase the danger of the occurrence of the injury.

Rapid and Highly Stable Membrane Reconstitution by LAiR Enables the Study of Physiological Integral Membrane Protein Functions.

Functional reintegration into lipid environments represents a major challenge for investigation of integral membrane proteins (IMPs). Here, we report a new approach, termed LMNG Auto-insertion Reintegration (LAiR), for reintegration of IMPs into lipid bilayers within minutes. The resulting proteoliposomes displayed an unprecedented capability to maintain proton gradients and long-term stability.
