Addressing Muscle Imbalance After Humerus Fracture: Treatment Options - Orthopedics

More Info

---

Addressing muscle imbalance after a humerus fracture can be a multifaceted process that involves understanding the underlying issues related to the fracture, the healing process, and the subsequent rehabilitation.
Firstly, regarding your question about the statement made by the physician that the bone could not heal completely and would leave a gap, this is often related to the nature of the fracture itself. In cases of spiral fractures, the bone may not align perfectly due to the twisting nature of the injury. This misalignment can lead to a non-union or malunion, where the bone heals in an incorrect position. The body may create a fibrous union instead of a solid bony union, which can lead to functional deficits and aesthetic concerns. The gap or misalignment can affect muscle attachment and function, contributing to the muscle imbalance you are experiencing.

Now, concerning the muscle imbalance, particularly the atrophy of the triceps muscle on the injured side, this is a common occurrence after a fracture. When a limb is immobilized, as in your case with a cast, the muscles can atrophy due to disuse. Even after the cast is removed, it can take time for the muscle to regain its strength and size. However, if you have been consistently training and still notice a significant difference, it may indicate that the muscle has not fully recovered or that there are other factors at play, such as nerve involvement or altered biomechanics.

To address the muscle imbalance and improve the appearance of your left arm, consider the following treatment options:
1. Physical Therapy: Engaging with a physical therapist who specializes in post-fracture rehabilitation can be beneficial. They can assess your range of motion, strength, and functional movement patterns. A tailored rehabilitation program can help you regain strength in the triceps and correct any biomechanical issues that may be contributing to the muscle imbalance.

2. Strength Training: Focus on targeted strength training exercises for the triceps and surrounding muscles. Incorporate unilateral exercises that specifically work the left arm, such as tricep extensions, push-ups, and resistance band exercises. Gradually increase the weight and intensity as your strength improves.

3. Functional Training: Incorporate functional movements that mimic daily activities and sports-specific actions. This can help improve coordination and muscle recruitment patterns, which may have been altered due to the injury.

4. Surgical Options: If the muscle imbalance is significant and does not improve with conservative measures, surgical options may be considered. This could involve procedures to correct any malunion or to enhance muscle attachment. However, surgery carries risks and should be discussed thoroughly with an orthopedic surgeon who specializes in upper extremity injuries.

5. Aesthetic Procedures: If your primary concern is cosmetic and you are looking for a more immediate solution, consult with a plastic surgeon or an orthopedic surgeon who specializes in aesthetic procedures. They can provide options for muscle augmentation or other techniques to improve the appearance of your arm.

6. Nutrition and Recovery: Ensure you are consuming a balanced diet rich in protein, vitamins, and minerals to support muscle recovery. Adequate hydration and rest are also crucial for muscle repair and growth.

In conclusion, while the initial injury and subsequent healing process may have led to the muscle imbalance you are experiencing, there are various treatment options available to help restore symmetry and function. It is essential to work closely with healthcare professionals to develop a comprehensive plan tailored to your specific needs and goals.
