Summary
Post-traumatic osteonecrosis of the proximal humerus is a complex issue following severe fractures. This review covers its risk factors, epidemiology, vascular supply, and treatment strategies.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Bone Biology
Background:
- Post-traumatic osteonecrosis of the proximal humerus is a significant complication.
- It frequently follows multi-fragmentary proximal humerus fractures.
- This condition can impair long-term functional recovery.
Purpose of the Study:
- To review current evidence on proximal humerus osteonecrosis.
- To identify risk factors and challenges in epidemiological estimation.
- To outline vascular supply, classification, and management.
Main Methods:
- Literature review of existing evidence.
- Synthesis of data on epidemiology and risk factors.
- Analysis of anatomical vascular supply to the humeral head.
Main Results:
- Osteonecrosis complicates severe proximal humerus fractures.
- Epidemiology is challenging to ascertain due to various factors.
- Understanding vascularity is key to classification and treatment.
Conclusions:
- Management of post-traumatic proximal humerus osteonecrosis requires careful consideration.
- Further research may clarify epidemiological data and refine treatment protocols.
- This review provides a comprehensive overview for clinicians.

01:19Bones of the Upper Limb: Humerus
13.9K
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
10.7K
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...

01:27Fractures: Bone Repair
6.7K
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...

01:09Bones of the Upper Limb: Radius
11.0K
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.
The radius has a nail-shaped head, and a...
