Summary
This study shows that multidirectional palmar fixed-angle plates effectively treat unstable distal radius fractures, enabling early patient mobilization and good functional recovery. The Aptus Radius plate system provides stable fixation for displaced distal radius fractures.
Area of Science:
- Orthopedic surgery
- Traumatology
- Biomechanical engineering
Background:
- Distal radius fractures are common injuries.
- Unstable fractures often require surgical intervention for optimal outcomes.
- Traditional fixation methods may have limitations in achieving stable reduction and early motion.
Purpose of the Study:
- To evaluate the efficacy of a multidirectional palmar fixed-angle plate system (Aptus Radius 2.5) for treating unstable distal radius fractures.
- To assess the ability of this system to provide stable fixation and allow early functional recovery.
- To determine if subchondral support prevents secondary dislocation.
Main Methods:
- A prospective study of 61 patients with unstable distal radius fractures treated with the Aptus Radius 2.5 plate system.
- No bone grafting was used.
- Postoperative radiographic assessment and clinical follow-up including DASH and Krimmer scores were performed on 55 patients.
Main Results:
- All fractures achieved anatomical reduction and united without complications.
- Excellent radiographic alignment was maintained at follow-up.
- Patients demonstrated good functional recovery with preserved range of motion and grip strength, indicated by low DASH and high Krimmer scores.
Conclusions:
- The Aptus Radius 2.5 multidirectional palmar fixed-angle plate system offers stable internal fixation for unstable distal radius fractures.
- This system facilitates early mobilization and good functional outcomes.
- The multidirectional fixation and dual screw lines ensure optimal restoration of the articular surface and subchondral support.

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.

Fractures: Bone Repair
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 procedure...

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...
