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. [1]
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 ...
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]
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 ...
The Hill equation reflects the occupancy of macromolecules: the fraction that is saturated or bound by the ligand. [1] [2] [nb 1] This equation is formally equivalent to the Langmuir isotherm. [3] Conversely, the Hill equation proper reflects the cellular or tissue response to the ligand: the physiological output of the system, such as muscle ...
They use the sensitivity and specificity of the test to determine whether a test result usefully changes the probability that a condition (such as a disease state) exists. The first description of the use of likelihood ratios for decision rules was made at a symposium on information theory in 1954. [ 1 ]
