Summary
Prosthetic lunate replacement for Kienböck disease can lead to dislocation years later. This case highlights a rare complication requiring further surgical intervention for wrist pain.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Musculoskeletal Disorders
Background:
- Kienböck disease is a rare condition affecting the lunate bone in the wrist.
- Traditional treatments include revascularization, fusions, or carpectomy with prosthetic lunate placement.
- Prosthetic lunate replacement, once favored, has declined due to complications like synovitis and arthritis.

01:15Bones 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...
01:09Bones 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.
