Below is a detailed overview of the standard treatment approaches for this specific type of fracture.

Overview of Lesser Tuberosity Fractures

The lesser tuberosity of the humerus is a small bony prominence located on the anterior aspect of the humerus, serving as an attachment point for the subscapularis muscle. Fractures in this area can occur due to trauma, such as falls or direct impacts, and may be associated with other shoulder injuries, including rotator cuff tears.

Conservative Treatment Approaches

1. Initial Assessment and Imaging

• Clinical Evaluation: A thorough physical examination is essential to assess the range of motion, pain levels, and any associated injuries.
• Imaging Studies: X-rays are typically the first step to confirm the fracture and evaluate its displacement. In some cases, MRI or CT scans may be necessary for a detailed assessment, especially if there is suspicion of associated soft tissue injuries[1].

2. Non-Surgical Management

• Immobilization: The affected arm may be placed in a sling to immobilize the shoulder and allow for healing. This is usually recommended for non-displaced fractures.
• Pain Management: Analgesics and anti-inflammatory medications can help manage pain and swelling.
• Physical Therapy: Once the initial pain subsides, physical therapy may be initiated to restore range of motion and strengthen the shoulder muscles. This typically begins with gentle passive movements and progresses to active exercises as tolerated[2].

Surgical Treatment Approaches

1. Indications for Surgery

• Surgery is generally indicated for displaced fractures, fractures with significant instability, or when there is associated injury to the rotator cuff or other structures. Surgical options may include:
  • Open Reduction and Internal Fixation (ORIF): This procedure involves surgically realigning the fracture fragments and securing them with plates and screws. This is often the preferred method for displaced fractures to ensure proper alignment and stability[3].
  • Arthroscopic Techniques: In some cases, minimally invasive arthroscopic surgery may be used to repair the fracture and any associated soft tissue injuries. This approach can reduce recovery time and minimize scarring[4].

2. Postoperative Care

• Rehabilitation: Post-surgery, a structured rehabilitation program is crucial. This typically includes:
  • Early Mobilization: Gentle range-of-motion exercises may begin shortly after surgery to prevent stiffness.
  • Strengthening Exercises: As healing progresses, strengthening exercises are introduced to restore function and stability to the shoulder.
• Follow-Up Imaging: Regular follow-up appointments and imaging studies may be necessary to monitor healing and ensure proper alignment of the fracture[5].

Conclusion

The management of a lesser tuberosity fracture of the humerus (ICD-10 code S42.26) involves a careful assessment of the fracture's characteristics and the patient's overall condition. While many cases can be effectively treated with conservative measures, surgical intervention may be necessary for more complex or displaced fractures. A comprehensive rehabilitation program is essential for optimal recovery and return to function. As always, treatment should be tailored to the individual patient, considering their specific needs and circumstances.
