Context: Arthroscopic surgical repair of the shoulder is recommended when conservative treatment for shoulder instability (SI) fails. However, many patients undergoing this procedure do not return to same level of activity.

A malunion as a complication of distal humerus fractures has been frequently linked with aesthetic problems but less frequently with posterolateral rotatory instability.

The etiology of the so-called posterolateral rotatory instability of the elbow is mostly traumatic, but iatrogenic causes have also been described such as the treatment of tennis elbow and less frequently and chronically due to overuse and overload because of

Reverse shoulder arthroplasty (RSA) is performed to decrease pain and improve function and range of motion (ROM) primarily for patients with rotator cuff arthropathy, an arthritis of the shoulder secondary to rotator cuff insufficiency. However, RSA has suffered from high early to mid-term rates of complication, with instability being one of the most common. The shoulder biomechanics post-RSA depend on multiple factors such as implant geometry, positioning, and cuff integrity.

Abstract:
The vast majority of shoulder complaints are due to soft tissue lesions, and rotator cuff disorders represent the largest diagnostic category of these. Many shoulder complaints are multifactorial in origin, and articular and extra-articular disorders can coexist. Instability also plays a major role; the shoulder is the most mobile joint of the body, achieving this mobility at the expense of its stability. Loss of the fine balance between optimal mobility of the joint and its stability is a common, albeit frequently subtle, feature of shoulder complaints....

We investigate and analyze the time dependence of the so-called differential entropy as a measure of the dynamical stability of a one-dimensional, propeller-shaped quantum Brownian molecular rotator. The larger the entropy change, the more profound the instability (lower control) of the rotator. The quantum molecular rotator is modelled by the quantum Caldeira-Leggett master equation while assuming the external harmonic field for the rotator. Rotational stability is found relatively high for the constructed Gaussian states, especially for molecules with a larger number of blades.

The non-linearity in the mass, stiffness or damping of the system may have provided a coupling or frequency transformation between the excitation forces and the subsynchronous vibrations.
