Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

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 of the...
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...

    Summary

    This case study details an acute traumatic dorsal distal radioulnar joint (DRUJ) dislocation treated with casting. The dislocation recurred after re-injury, but long-term follow-up showed no pain or activity restrictions.

    Area of Science:

    • Orthopedic Surgery
    • Traumatology
    • Sports Medicine

    Background:

    • Isolated acute distal radioulnar joint (DRUJ) dislocations are rare injuries.
    • Reports of DRUJ luxations are infrequent, often presented as isolated case reports.

    Purpose of the Study:

    • To present a case of acute traumatic dorsal DRUJ dislocation.
    • To evaluate the outcome of cast immobilization and subsequent recurrence.

    Main Methods:

    • A case of acute traumatic dorsal DRUJ dislocation was treated with cast immobilization.
    • The patient experienced recurrence after subsequent trauma.
    • Follow-up was conducted 17 months after the initial event and 9 months after recurrence.

    Main Results:

    • The patient experienced recurrence of the dorsal DRUJ dislocation after new trauma.
    • At 17-month follow-up, the patient reported no pain.
    • No restrictions in work or sports-related activities were noted at follow-up.

    Conclusions:

    • Cast immobilization can be a treatment option for acute traumatic dorsal DRUJ dislocations.
    • Recurrence is possible after initial treatment, even with conservative management.
    • Despite recurrence, patients may achieve good functional outcomes with long-term follow-up.
