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...

Summary
This summary is machine-generated.

Radial head fractures are common elbow injuries. Treatment for these fractures depends on fragment number, displacement, and associated injuries, guiding decisions from early motion to radial head replacement.

Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Musculoskeletal imaging

Background:

  • Radial head fractures are the most frequent elbow fractures.
  • These fractures often occur with other injuries, complicating treatment.
  • Treatment planning requires integrating clinical presentation, physical examination, and imaging findings.

Purpose of the Study:

  • To outline the decision-making process for managing radial head fractures.
  • To correlate fracture characteristics with optimal treatment strategies.
  • To review current evidence for various treatment options.

Main Methods:

  • Review of clinical presentation, physical examination, and imaging characteristics of radial head fractures.
  • Analysis of treatment options including non-surgical management, fragment excision, open reduction internal fixation (ORIF), and radial head replacement (arthroplasty).
  • Consideration of fracture characteristics (fragment number, displacement, impaction, bone quality) and associated injuries in treatment selection.

Main Results:

  • Minimally displaced fractures without mechanical block are managed non-surgically with early range of motion (ROM).
  • Displaced fractures with fewer than 3 fragments can be treated non-surgically or with ORIF, with no clear superiority of either method.
  • Displaced fractures with 3 or more fragments benefit from radial head replacement.
  • Radial head arthroplasty is favored over fixation in cases with ligamentous injury compromising joint stability.

Conclusions:

  • Fracture characteristics are pivotal in determining the optimal treatment for radial head fractures.
  • Early motion is suitable for stable, minimally displaced fractures.
  • Radial head replacement offers a reliable solution for complex fractures and those with associated instability.
