Spinal Nerves: Plexus I01:22

Spinal 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.

Bones of the Upper Limb: Radius01:09

Bones 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.
The radius has a nail-shaped head, and a short...
Assessment of radial pulse01:11

Assessment of radial pulse

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:
Assessment of apical radial pulse01:25

Assessment of apical radial pulse

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.

Arteries of the Upper Limbs01:12

Arteries 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...
Bones of the Upper Limb: Ulna01:15

Bones 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...

Area of Science:

  • Neurology
  • Orthopedic Surgery
  • Traumatology

Background:

  • Acute radial nerve palsy can occur after blunt trauma without associated fractures or dislocations.
  • Conservative management with a long-arm cast was initially applied to the patient.
  • Preoperative assessment included electromyoneurography and MRI to evaluate the nerve injury.

Observation:

  • A 45-year-old male sustained blunt trauma resulting in radial nerve palsy.
  • The injury was located at the humeral groove, classified as a second-degree nerve injury.
  • Preoperative wrist extension strength was graded at 2/5 using the British Medical Research Council (MRC) scale.

Findings:

  • Surgical intervention was performed under general anesthesia.
  • The patient achieved complete recovery of wrist and finger extension function.
  • Full motor recovery was observed within a six-month postoperative period.

Implications:

  • Detailed clinical and electrodiagnostic evaluation is crucial for determining optimal treatment (conservative vs. surgical) for radial nerve injuries.
  • Prompt surgical intervention may be indicated for certain degrees of nerve injury to restore function.
  • This case underscores the potential for significant functional recovery following appropriate management of traumatic radial nerve palsy.
