Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

3.2K
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.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

10.6K
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...

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:

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.2K
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...

Radial System Protection01:23

Radial System Protection

463
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

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.

Area of Science:

  • Orthopedics
  • Neurology
  • Traumatology

Background:

  • The radial nerve is the most frequently injured major nerve in the upper limb due to its anatomical proximity to the humeral shaft.
  • Vulnerability to injury is heightened during humeral fractures and gunshot wounds, as well as iatrogenic causes during surgery.

Purpose of the Study:

  • To provide a comprehensive overview of radial nerve injuries, including their causes, treatment modalities, and outcomes.
  • To highlight the importance of conservative management and indications for surgical intervention.

Main Methods:

  • Review of current literature on radial nerve injuries.
  • Discussion of various treatment strategies, from conservative measures to surgical techniques like nerve grafting and biological therapy.

Main Results:

  • Radial nerve injuries are common, particularly with humeral fractures.
  • Non-operative treatment is the mainstay, focusing on maintaining joint mobility.
  • Surgical intervention is indicated for nerve transection or lack of improvement with conservative care.

Conclusions:

  • Radial nerve injuries, while frequent, typically yield satisfactory results due to being the least debilitating upper limb nerve injury.
  • A combination of conservative and surgical approaches, including newer biological therapies, can effectively manage these injuries.
