Summary
This case report details a rare Salter type 3 proximal humerus fracture with posterior dislocation in a teen. MRI was crucial for diagnosis, and while surgery led to good motion, avascular necrosis developed.
Area of Science:
- Orthopedic Surgery
- Pediatric Traumatology
- Radiology
Background:
- Salter type 3 physeal fractures of the proximal humerus are uncommon pediatric injuries.
- Posterior dislocation of the proximal humerus is a rare complication.
Observation:
- A 16-year-old boy presented with a Salter type 3 physeal fracture and posterior proximal humerus dislocation.
- Standard radiography was insufficient; MRI revealed the humeral head locked behind the glenoid labrum.
Findings:
- Open reduction was required for treatment.
- Postoperatively, Magnetic Resonance Imaging (MRI) and radiography detected avascular necrosis of the humeral head 16 months after surgery.
- Despite full range of motion and absence of pain, long-term monitoring is recommended.
Implications:
- This case highlights the diagnostic utility of MRI in complex physeal fractures with dislocation.
- It underscores the potential for avascular necrosis development even with successful initial reduction and functional recovery.
- Emphasizes the need for vigilant, long-term follow-up in similar pediatric shoulder injuries.

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...

Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

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.
The radius has a nail-shaped head, and a short...
