X-ray at right shows same shoulder after reduction and internal rotation, revealing both a Bankart lesion and a Hill-Sachs lesion. Diagnosis can be suspected by history and physical examination which is usually followed by imaging. Because of the mechanism of injury, apprehension of anterior dislocation is common with provocative maneuvers.
Small-angle X-ray scattering (SAXS) is a small-angle scattering technique by which nanoscale density differences in a sample can be quantified. This means that it can determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes and characteristic distances of partially ordered materials.

GISAS combines the accessible length scales of small-angle scattering (SAS: SAXS or SANS) and the surface sensitivity of grazing incidence diffraction (GID). Geometry of a GISAS experiment. The incident beam strikes the sample under a small angle close to the critical angle of total external x-ray reflection.
MRI of shoulder after dislocation with Hill-Sachs lesion and labral Bankart's lesion. In young adults engaged in highly demanding activities shoulder surgery may be considered. [25] Arthroscopic surgery techniques may be used to repair the glenoidal labrum, capsular ligaments, biceps long head anchor or SLAP lesion or to tighten the shoulder ...
It is an indication for surgery and often accompanied by a Hill-Sachs lesion, damage to the posterior humeral head. [5] A bony Bankart is a Bankart lesion that includes a fracture of the anterior-inferior glenoid cavity of the scapula bone. [6] The Bankart lesion is named after English orthopedic surgeon Arthur Sydney Blundell Bankart (1879 ...
In terms of modelling, small-angle X-ray and neutron scattering data can be combined with the program MONSA. An example in which SAXS, SANS and EM data has been used to build an atomic model of a large multi-subunit enzyme has recently been published. [3] For some examples of this method see. [4]
Cells are least sensitive when in the S phase, then the G 1 phase, then the G 2 phase, and most sensitive in the M phase of the cell cycle.This is described by the 'law of Bergonié and Tribondeau', formulated in 1906: X-rays are more effective on cells which have a greater reproductive activity.
Sensitivity testing results can allow a clinician to change the choice of antibiotics from empiric therapy, which is when an antibiotic is selected based on clinical suspicion about the site of an infection and common causative bacteria, to directed therapy, in which the choice of antibiotic is based on knowledge of the organism and its ...
