Summary
Semiconstrained elbow replacement effectively treats distal humeral nonunion in elderly patients, significantly improving pain and function. This joint replacement arthroplasty offers a reliable alternative to repeated osteosynthesis, which is often ineffective.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
Background:
- Distal humeral nonunion is a challenging condition, particularly in elderly patients.
- Repeated osteosynthesis has demonstrated limited efficacy for this condition.
Purpose of the Study:
- To evaluate the safety and efficacy of semiconstrained elbow replacement for treating distal humeral nonunion.
Main Methods:
- Retrospective review of 36 patients undergoing semiconstrained elbow replacement for distal humeral nonunion.
- Analysis of patient outcomes, including pain levels, range of motion, stability, and complications.
Main Results:
- 86% of patients reported satisfactory results with significant pain reduction and improved range of motion.
- Elbow replacement arthroplasty led to stable extremities in all cases of flail involvement.
- Complications occurred in 18% of patients, with 13% requiring reoperation.
Conclusions:
- Semiconstrained elbow replacement is a safe and reliable treatment for distal humeral nonunion.
- This arthroplasty provides a significant advancement over ineffective repeated osteosynthesis methods.

01:19Bones 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...
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.
