Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

4.0K
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

3.7K
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 Repair01:27

Fractures: Bone Repair

4.4K
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...

Summary

Distal radius malunion (DRMU) is improper healing of a distal radius fracture, causing wrist dysfunction. Surgical correction via osteotomy can restore anatomy and improve function.

Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Hand Surgery

Background:

  • Distal radius malunion (DRMU) results from non-anatomical healing of distal radius fractures.
  • DRMU leads to impaired wrist function, including restricted motion, decreased strength, and pain.
  • Associated complications can include nerve/tendon involvement, carpal malalignment, and ulnar-carpal impingement.

Purpose of the Study:

  • To outline the diagnostic imaging and surgical management of distal radius malunion.
  • To detail the anatomical and functional consequences of DRMU.
  • To describe current surgical techniques for correcting DRMU.

Main Methods:

  • Diagnostic imaging typically includes X-ray and CT; CT-arthrography is crucial for intra-articular DRMU.
  • Surgical intervention is guided by clinical assessment and involves osteotomy (opening or closing wedge) to restore distal radial anatomy.
  • Bone grafting or bone substitutes may be necessary; computer-assisted planning is recommended.

Main Results:

  • DRMU significantly alters wrist biomechanics and can progress to radiocarpal osteoarthritis.
  • Surgical correction aims to restore the native anatomy of the distal radius.
  • Associated ulnar osteotomy may be performed, and palliative procedures are options for specific patient groups.

Conclusions:

  • Accurate imaging is essential for diagnosing and planning the treatment of DRMU.
  • Surgical correction through osteotomy is the primary method for restoring function in DRMU.
  • Management strategies should be tailored to the specific type of malunion and patient factors.
