Summary
Darrach resection for distal radioulnar joint instability causes stump problems. New implants preserve ligaments and restore joint function, offering better treatment options for forearm rotation issues.
Area of Science:
- Orthopedic surgery
- Biomechanics
- Reconstructive surgery
Background:
- Darrach resection is standard for distal radioulnar joint (DRUJ) issues but causes ulnar stump instability.
- The ulnar head is crucial for DRUJ function and distal forearm stability during rotation.
Purpose of the Study:
- To evaluate the role of the ulnar head in DRUJ function.
- To introduce novel DRUJ implants for improved patient treatment.
Main Methods:
- Development and application of partial resurfacing and modular ulnar head implants for DRUJ reconstruction.
- Assessment of implant function in primary, revision, and salvage procedures.
Main Results:
- Partial resurfacing implants preserve ligamentous attachments and DRUJ stability in primary cases.
- Modular ulnar head implants restore ulnar head offset and stabilize the stump in revision/salvage scenarios.
Conclusions:
- Novel DRUJ implants address limitations of Darrach resection.
- These implants offer solutions for a majority of DRUJ prosthesis indications, restoring pain-free function.

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: 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.

Bones of the Upper Limb: Humerus
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...
