Stacked Rayleigh-Taylor Instabilities Grow Drops into Soft Stalactitelike Structures.

The interplay between thin film hydrodynamics and solidification produces formidably intricate geophysical structures, such as stalactites and icicles, whose shape is a testimony of their long growth. In simpler settings, liquid films can also produce regular patterns. When coated on the underside of a flat plate, these films are unstable and yield lattices of drops following the Rayleigh-Taylor instability.

The Outcome Of Surgical Management Of Chronic Pectoralis Major Ruptures In Weightlifters.

Pectoralis major repair is increasing in frequency due to the uptake of weight training. Chronic tendon injuries tend not to have as favourable outcomes. We report our outcome of chronic pectoralis major ruptures following surgical repair.

Arthroscopic plication for multidirectional instability: 50 patients with a minimum of 2 years of follow-up.

Background: Treatment of patients who have not improved after physiotherapy for multidirectional instability (MDI) remains challenging, with no agreed best practice. The purpose of this study was to ascertain whether arthroscopic plication is safe and effective for these patients.

Methods: Fifty consecutive patients who had not improved after at least 6 months of specialized shoulder physiotherapy for symptomatic MDI and no labral lesion at arthroscopy underwent arthroscopic plication between 2006 and 2013.

The use of shoulder scoring systems and outcome measures in the UK.

Introduction: In future, outcomes following shoulder surgery may be subject to public survey. Many outcome measures exist but we do not know whether there is a consensus between shoulder surgeons in the UK. The aim of this study was to survey the preferred outcome measures used by National Health Service (NHS) shoulder surgeons operating in the UK.
