Proximal humerus head-splitting fracture associated with single-part anterior dislocation
- Humeral başı split kırıkları nadir görülen ve özellikle anterior çıkıklı vakalarda parçaların subskapularis kası arasına sıkışması nedeniyle cerrahi zorluk teşkil eden yaralanmalardır.
- Ameliyat öncesi bilgisayarlı tomografi (BT) çekilmesi, kırık deplasmanını doğru değerlendirmek ve etkili bir cerrahi planlama yapmak için hayati önem taşır.
- Genç ve aktif hastalarda omuz ekleminin anatomik bütünlüğünü ve fonksiyonunu geri kazanmak için açık anatomik redüksiyon ve internal fiksasyon (ORIF) öncelikli tedavi yöntemidir.

Understanding Rare Humeral Head Split Fractures
Humeral head split fractures are exceptionally rare clinical occurrences that present significant challenges in orthopedic surgery. While the split fragment in these injuries is typically associated with posterior dislocation, certain complex cases involve an anteriorly dislocated fragment. In these specific instances, the split part becomes trapped between the anterior glenoid and the subscapularis muscle, requiring a specialized approach for successful management.
The Importance of Preoperative Diagnostic Imaging
In the management of complex shoulder traumas, the acquisition of preoperative CT results is considered vital. Detailed imaging is essential to accurately visualize the displacement and formulate effective exposure and reduction strategies. Without comprehensive CT data, planning the surgical path becomes significantly more difficult, increasing the risk of intraoperative complications.
Surgical Treatment Standards for Young Active Adults
For young and active patients, the primary goal of treatment is to restore the anatomical integrity of the shoulder joint. Clinical evidence suggests that open anatomic reduction and internal fixation (ORIF) should be considered the first treatment of choice. This approach ensures the best possible functional recovery by providing stable fixation and precise alignment.
Key Clinical Considerations
To summarize the management protocol for these rare fractures, the following points are critical:
- Dislocation Pattern: Be aware that while posterior dislocation is common, anterior displacement can occur and involve the subscapularis muscle.
- Diagnostic Necessity: Utilize preoperative CT scans as a mandatory tool for surgical planning.
- Primary Intervention: Prioritize open anatomic reduction to achieve optimal outcomes in active populations.
- Fixation Method: Implement internal fixation to maintain the reduction during the healing process.
