Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

8.9K
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...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

11.3K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

9.0K
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...

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

Muscles of the Forearm that Move the Hand and Fingers

3.4K
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...

Anatomical Movements00:51

Anatomical Movements

13.8K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

3.4K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Summary

A novel triangular holder offers a cost-effective, mobile, and radiolucent tower for wrist arthroscopy. This adaptable tool can benefit surgical practices prioritizing budget-friendly solutions.

Area of Science:

  • Orthopedic Surgery
  • Surgical Technology
  • Minimally Invasive Procedures

Background:

  • Wrist arthroscopy requires specialized equipment, including towers to position the arthroscope.
  • Commercially available towers can be expensive and may lack mobility or radiolucency.
  • Cost-effectiveness is a significant consideration for many surgical practices.

Purpose of the Study:

  • To describe the use of a triangular holder as an alternative tower for wrist arthroscopy.
  • To evaluate the utility of this holder in a cost-conscious surgical setting.

Main Methods:

  • A triangular holder was adapted for use as a mobile, radiolucent tower during wrist arthroscopy procedures.
  • The holder's performance, cost, and practical application were assessed.
