Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.4K
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

3.6K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.5K
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 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: Humerus01:19

Bones of the Upper Limb: Humerus

3.8K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomedical Engineering

Background:

  • Non-reconstructible radial head fractures often involve concomitant injuries, leading to elbow instability.
  • Radial head prosthesis implantation is a common treatment for such complex fractures.

Purpose of the Study:

  • To provide practical tips and tricks for the successful surgical implantation of radial head prostheses.
  • To outline essential aftercare protocols following prosthesis implantation.
  • To review the long-term outcomes and revision rates associated with radial head prostheses.

Main Methods:

  • Review of current prosthetic designs and implantation techniques.
  • Discussion of common surgical pitfalls and strategies to avoid them.
  • Analysis of literature regarding long-term patient outcomes and revision surgery data.

Main Results:

  • Successful implantation requires careful attention to specific surgical techniques and potential complications.
  • Adherence to recommended aftercare protocols is crucial for optimal functional recovery.
  • Long-term outcomes vary, with revision rates influenced by prosthesis type, surgical technique, and patient factors.

Conclusions:

  • Radial head prosthesis implantation is an effective treatment for unstable elbow fractures when performed with meticulous technique.
  • Proper patient selection, surgical execution, and post-operative management are key to minimizing complications and maximizing success.
  • Understanding long-term outcomes and revision rates is essential for informed clinical decision-making and patient counseling.
