Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

3.8K
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...

Fractures: Bone Repair

4.1K
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...

Radial System Protection01:23

Radial System Protection

173
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

3.4K
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...

Assessment of radial pulse01:11

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

1.4K
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...

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Radiology

Background:

  • Radial head fractures are the most frequent elbow fractures.
  • They frequently occur with associated ligamentous, cartilaginous, or other fractures.
  • Associated injuries significantly influence fracture management strategies.

Purpose of the Study:

  • To review the diagnosis and management of radial head fractures.
  • To highlight the importance of identifying and treating associated injuries.
  • To discuss current treatment options, including conservative and operative interventions.

Main Methods:

  • Review of current literature on radial head fracture management.
  • Discussion of diagnostic modalities, including CT scans.
  • Analysis of various surgical techniques: excision, open reduction internal fixation (ORIF), and prosthetic replacement.

Main Results:

  • Modified Mason classification incorporates associated injuries.
  • CT scans aid in diagnosis.
  • Non-operative treatment for undisplaced fractures.
  • Headless cannulated screws preferred for displaced fractures due to stability and minimal invasiveness.
  • Plate fixation for comminuted neck fractures.
  • Excision for unfixable fractures in the elderly; prosthetic replacement for younger patients or those with severe associated injuries.

Conclusions:

  • Accurate diagnosis of radial head fractures and associated injuries is crucial.
  • Treatment should be individualized based on fracture pattern and associated injuries.
  • Headless cannulated screw fixation offers advantages for displaced fractures.
  • Surgical options like excision or prosthetic replacement are reserved for specific complex cases.
