Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

10.8K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Imaging Studies for Cardiovascular System III: X-Ray

621
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.5K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

X-ray Imaging01:24

X-ray Imaging

11.0K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

2.9K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Area of Science:

  • Orthopedics
  • Radiology
  • Anatomy

Background:

  • The wrist's intricate anatomy and biomechanics lead to diverse instability patterns.
  • Several classification systems exist for carpal instability, with the Mayo classification being widely adopted.

Purpose of the Study:

  • To emphasize the importance of the Mayo classification for carpal instability.
  • To guide the interpretation of imaging and improve physician communication.

Main Methods:

  • Review of existing literature and classification schemes.
  • Discussion of imaging modalities for carpal instability assessment.

Main Results:

  • The Mayo classification provides a standardized framework for carpal instability.
  • Understanding this classification is crucial for accurate diagnosis and treatment planning.

Conclusions:

  • The Mayo classification is essential for diagnosing and communicating about wrist carpal instability.
  • Standard and stress radiographs are primary imaging tools, supplemented by other modalities.
