It is advisable to delay the application of dressings until swelling has subsided. During this time, the patient should be in bed with the injured arm supported on a pillow and ice applied intermittently. If acute flexion is employed, layers of gauze should absorb secretions and prevent skin chafing. The inner surface of the arm and forearm must not come into contact with the chest to avoid irritation. A strip of adhesive encircles the wrist and passes over the shoulder for securing the upper extremity in a position from semi-flexion to acute flexion, allowing gradual increase in flexion as swelling subsides. If additional security is needed, an axillary pad can be used. For immobilizing the forearm between complete extension and semiflexion, plaster splints are usually most satisfactory.
Operative treatment may be necessary if ordinary methods are not efficient. The open method often yields better results but requires a thorough understanding of the anatomy of the lower humerus to avoid harm. Wire or nails should rely on compact tissue for stability. Incisions must avoid injuring critical nerves and arteries around the elbow joint. After exposing the bone, analyze fracture lines and forces preventing reduction before placing fixation materials.
After-treatment involves careful monitoring to prevent constriction and ensure proper splint positioning. Passive motion and massage can begin once swelling subsides but should be gentle and under a surgeon's guidance to avoid fragment displacement. The prognosis varies based on patient age, severity of the fracture, and whether it enters the joint cavity.

Prognosis is generally favorable if accurate reduction and internal fixation are achieved, followed by early passive motion. However, complications such as Volkmann's contracture can occur due to constriction from dressings.
Key Takeaways
- Delay dressing application until swelling subsides.
- Use gauze and padding to prevent skin irritation during immobilization.
- Operative treatment may be necessary for complex fractures.
- Careful monitoring is essential in the after-treatment phase.
Practical Tips
- Apply ice intermittently to reduce swelling before dressing application.
- Gradually increase flexion as swelling decreases post-injury.
- Use axillary pads and adhesive strips for additional immobilization security.
Warnings & Risks
- Avoid entering the olecranon or coronoid fossa during surgery.
- Monitor closely for constriction to prevent Volkmann's contracture.
Modern Application
While some techniques like using ice caps and gauze layers are still relevant today, modern medical practices have advanced surgical methods and materials. However, the principles of careful monitoring and gradual rehabilitation remain crucial in preventing complications such as Volkmann's contracture.
Frequently Asked Questions
Q: What is the recommended position for immobilizing a fractured lower humerus?
The injured arm should be supported on a pillow with intermittent ice application until swelling subsides. Acute flexion can be employed, but it must be gradually increased as swelling decreases.
Q: Why is careful monitoring necessary during the after-treatment phase?
Careful monitoring helps prevent constriction and ensures proper splint positioning, which are crucial to avoid complications such as Volkmann's contracture.
Q: What surgical approach is recommended for complex fractures of the lower humerus?
The open method is often preferred for its better results but requires a thorough understanding of the anatomy and careful avoidance of critical nerves and arteries around the elbow joint.
