What Is the Clinical Value of Long Head of Biceps Tendon Tests in Distal Supraspinatus Tendon Rupture? A Prospective Multicenter Study.

Purpose: The purpose of this study was to determine the clinical value of diagnostic tests for the long head of the biceps tendon (LHBT) injuries in the setting of a Patte stage 1 supraspinatus tendon rupture.

Methods: This was a prospective cohort multicenter study of 361 patients aged 30 to 80 years with Patte stage 1 distal supraspinatus tendon rupture. The LHBT was assessed clinically by palpation of the bicipital groove, the speed test, the Yergason test and the Kibler test.

Ternary recombination of excited Ar+(P1/22) ions, established experimental results reinterpreted with a new extended model.

For many years, the recombination of excited ions of argon, Ar+(P1/22), has been assumed negligible under ambient conditions as compared to the recombination of ground-state ions, Ar+(P3/22). This opinion was confronted with detailed experimental results that seem to clearly support it. Here, we propose a new interpretation in light of our recent calculations, which shows that the recombination efficiency is comparable for both fine-structure states.

Rotational Transitions in the N Ion Induced by Collisions with Helium Atoms in Cold Helium Plasmas. A Quasiclassical Trajectory Study.

Cross-sections of state-to-state rotational transitions in electronically ground-state (X ) ions induced by collisions with He atoms have been calculated using a quasiclassical trajectory method and a set of artificial neural networks representing the /He potential energy surface. The training points for the neural networks have been calculated at a MCSCF (multi-configuration self-consistent field)/aug-cc-pVQZ level. A broad range of the /He collision energy has been considered (  eV) and the efficiency of vibrational transitions in the ion has also been analyzed.

Methods of analyzing the long head of the biceps tendon in the management of distal supraspinatus tendon ruptures. Part 2: The role and validation of an arthroscopic exploration protocol of the long head of the biceps tendon.

Introduction: Inter-observer arthroscopic assessments of the Long head of the Biceps tendon (LHB) injuries, in the absence of predefined instructions, are poorly reproducible. There are several types of LHB injuries, of varying severity, which can make its intraoperative analysis subjective.

Hypothesis: The application of a precise arthroscopic exploration protocol, particularly dynamic, associated with an equally precise analysis of the possible tendon lesions, intrinsic or extrinsic, makes it possible to obtain a reproducible analysis of the lesions of the LHB and aid decision-making around its conservation or its resection, in distal supraspinatus tendon ruptures.

Methods to analyse the long head of the biceps in the management of distal ruptures of the supraspinatus tendon. Part 1: the concept of the "biceps box": dynamic rotator interval approach. Incidence of lesions of the long head of the biceps tendon.

Introduction: The area encompassing the long head of the biceps (LHB) can be represented as a rectangular parallelepiped. This geometric view can be likened to a box, the "biceps box", where the sides are the extrinsic structures and the LHB is the intrinsic structure. Since these structures are mobile in relation to each other, a dynamic "biceps box" model can modify assessments of the LHB, in its healthy or pathological state, and make the therapeutic approach to treating LHB lesions less arbitrary.
