Summary
A new lateral approach for radiocarpal arthrography offers an alternative to traditional dorsal techniques for evaluating wrist pain and instability.
Area of Science:
- Orthopedic imaging and interventional procedures.
- Radiocarpal joint diagnostics.
Background:
- Conventional dorsal approaches are standard for radiocarpal arthrography.
- Alternative techniques may offer benefits in specific clinical scenarios.
Purpose of the Study:
- To describe and evaluate a lateral approach technique for radiocarpal arthrography.
- To present a viable alternative to existing dorsal methods.
Main Methods:
- Detailed description of the radiocarpal arthrography technique utilizing a lateral entry point.
- Application of the technique for diagnostic purposes in patients with wrist conditions.
Main Results:
- Successful implementation of the lateral approach for radiocarpal arthrography was demonstrated.
- The technique provides a functional alternative to conventional dorsal methods.
Conclusions:
- The lateral approach for radiocarpal injection is a safe and effective alternative.
- It aids in the assessment of wrist pain and instability, complementing dorsal techniques.

01:09Bones of the Upper Limb: Radius
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.

01:15Bones of the Upper Limb: Ulna
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 of the...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
