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...
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Radial System Protection01:23

Radial System Protection

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,...
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...
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:
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...

Summary
This summary is machine-generated.

Radial head fractures are common elbow injuries. Nonoperative treatment is effective for undisplaced fractures, while optimal surgical indications for displaced fractures and outcomes of radial head replacement for comminuted fractures require further study.

Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Radiology

Background:

  • Radial head fractures are the most frequent elbow fractures.
  • These injuries often involve associated ligamentous, cartilaginous, or other bony damage.
  • Accurate diagnosis relies on clinical assessment and radiological imaging.

Purpose of the Study:

  • To review the management strategies for radial head fractures.
  • To identify the optimal treatment for displaced partial articular radial head fractures.
  • To evaluate the outcomes of radial head replacement for comminuted fractures.

Main Methods:

  • Review of clinical assessment and radiological diagnostic methods.
  • Analysis of nonoperative management outcomes for undisplaced fractures.
  • Discussion of surgical indications and outcomes for displaced and comminuted fractures.

Main Results:

  • Undisplaced or minimally displaced radial head fractures without rotational block achieve excellent results with nonoperative management.
  • The threshold displacement for superior surgical outcomes in partial articular fractures remains undetermined.
  • Medium-term data indicate favorable outcomes for comminuted radial head fractures treated with radial head replacement.

Conclusions:

  • Nonoperative management is suitable for select radial head fractures.
  • Further research is needed to define surgical criteria for displaced fractures.
  • Radial head replacement shows promise for comminuted radial head fractures.
