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...

Early primary ligament repair for acute unstable elbow dislocations is effective. This surgical approach restores elbow stability, enabling early joint mobilization and good functional outcomes.

Area of Science:

  • Orthopedic Surgery
  • Traumatology

Background:

  • Acute unstable elbow dislocations often require surgical intervention.
  • Limited data exists on the efficacy of early primary ligament repair for these injuries.

Purpose of the Study:

  • To evaluate the clinical outcomes of early primary ligament repair in patients with acute unstable elbow dislocations.
  • To assess the effectiveness of this surgical technique followed by protected early joint mobilization.

Main Methods:

  • Retrospective review of 13 patients (11 male, 2 female; average age 37) with unstable elbow dislocations without fractures.
  • Surgical repair of medial and/or lateral structures based on intraoperative stability assessment.
  • Protected early joint mobilization exercise post-surgery.

Modified Long Head of Biceps Tendon Rerouting and Fixation as Partial Capsular Reconstruction for Massive Irreparable Rotator Cuff Tears

Published on: March 6, 2026

Main Results:

  • All patients achieved stable elbows post-operation, with no recurrent dislocations or subluxations.
  • Mean Mayo Elbow Performance Score was 93.5; 10 patients returned to previous work within 3.5 months.
  • Complications included heterotopic ossification (6 patients) and mild ulnar nerve symptoms (3 patients).

Conclusions:

  • Primary ligament repair for acute unstable elbow dislocations is a successful surgical strategy.
  • The procedure provides sufficient stability to permit early mobilization and good functional recovery.
  • This approach facilitates a quicker return to pre-injury activities.
