Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

4.3K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

4.0K
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...

Fractures: Bone Repair

4.7K
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: Humerus01:19

Bones of the Upper Limb: Humerus

6.6K
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
  • Bone Healing

Background:

  • Malunion is the most frequent complication of non-surgical distal radius fracture treatment.
  • Symptomatic malunion often necessitates corrective osteotomy, posing surgical challenges with variable outcomes.

Purpose of the Study:

  • To discuss the challenges and potential improvements in surgical correction of distal radius malunion.
  • To highlight strategies for preventing malunion and optimizing surgical outcomes.

Main Methods:

  • Review of current literature on distal radius fracture malunion.
  • Discussion of established and emerging surgical techniques for malunion correction.
  • Exploration of the role of advanced technologies in surgical planning and execution.

Main Results:

  • Maintenance of volar cortical contact and use of volar fixed-angle devices may obviate the need for bone grafting in some malunion corrections.
  • New technologies like 3-dimensional modeling and computer-generated osteotomy guides show promise for enhancing surgical treatment outcomes.

Conclusions:

  • Preventing distal radius fracture malunion is the optimal approach.
  • Advanced technologies are expected to positively influence the results of surgical malunion correction.
