• Ice Application: Applying ice to the affected area can help reduce swelling and alleviate pain. This should be done for 15-20 minutes every few hours during the initial days following the injury[4].

2. Pain Management

• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are commonly prescribed to manage pain and inflammation. In some cases, stronger pain relief may be necessary, depending on the severity of the injury[5].

3. Physical Therapy

• Rehabilitation Exercises: Once the acute pain subsides, physical therapy is crucial for restoring range of motion and strengthening the shoulder muscles. A physical therapist will design a tailored exercise program that gradually increases in intensity[6].

• Proprioceptive Training: This involves exercises that enhance the body’s ability to sense joint position, which is vital for preventing future dislocations or subluxations[7].

4. Surgical Intervention

• Indications for Surgery: If conservative management fails to stabilize the shoulder or if there are recurrent episodes of subluxation, surgical options may be considered. Surgical procedures can include arthroscopic stabilization techniques or open surgery to repair any damaged ligaments or tendons[8].

• Postoperative Care: Following surgery, a structured rehabilitation program is essential to ensure proper healing and restore function. This typically involves a period of immobilization followed by gradual reintroduction of movement and strengthening exercises[9].

Conclusion

The management of posterior subluxation of the left humerus (ICD-10 code S43.022) typically begins with conservative measures, including rest, immobilization, and pain management, followed by physical therapy to restore function. In cases where conservative treatment is ineffective, surgical options may be explored. It is crucial for patients to follow a comprehensive rehabilitation program to prevent recurrence and ensure optimal recovery. Always consult with a healthcare professional for personalized treatment plans tailored to individual needs and circumstances.
