Summary
Managing complex proximal humerus fractures often requires shoulder arthroplasty. This approach, when using fracture-specific prostheses, aids in anatomic tuberosity healing and augmented osteosynthesis for better outcomes.
Area of Science:
- Orthopedic surgery
- Trauma management
- Shoulder reconstruction
Background:
- Four-part proximal humerus fractures are challenging upper extremity trauma cases.
- Many of these fractures are unsuitable for standard operative fixation.
Purpose of the Study:
- To evaluate shoulder arthroplasty as a primary surgical treatment for four-part proximal humerus fractures.
- To highlight the role of fracture-specific prostheses in achieving anatomic tuberosity osteosynthesis.
Main Methods:
- Surgical management of four-part proximal humerus fractures using fracture-specific prostheses.
- Focus on timely reestablishment of the Gothic arch for tuberosity healing.
Main Results:
- Shoulder arthroplasty, when utilizing fracture-specific implants, reliably achieves anatomic tuberosity osteosynthesis.
- Prosthetic implantation effectively supplements anatomic tuberosity reconstruction.
Conclusions:
- Shoulder arthroplasty for fractures should be viewed as augmented osteosynthesis.
- Ongoing research explores enhanced tuberosity healing in elderly patients using specialized implants and biologic substrates.

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...
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...
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.
