Simple Elbow Dislocations: Evaluation, Management, and Outcomes

Abstract

Elbow dislocations are common athletic injuries and occur during a fall onto an outstretched hand as a combination of axial-compressive and rotational-shear forces are conducted across the elbow joint. Simple dislocations are those that involve purely ligamentous injury, while complex dislocations include periarticular fractures. The initial assessment, radiographic evaluation, and on-field treatment of these injuries is discussed. Multiple reduction techniques are described with the patient positioned both supine and prone. Definitive management involves primarily nonoperative treatment with limited immobilization and early active range of motion to minimize joint contracture and hasten return to pre-injury activities. For unstable elbows, surgical treatment is usually appropriate. Operative management may involve exploration, lateral ligament repair or reconstruction, and assessment of the need for medial ligament repair or reconstruction. The role of arthroscopic and arthroscopically assisted surgery for elbow dislocation is evolving. Clinical series have shown that extended periods of immobilization (> 3 weeks) are associated with poor outcomes. Early active range of motion should be initiated as early as possible because late or recurrent instability is uncommon. Contracture is the most common adverse sequela of elbow dislocation. The literature indicates an average of 3° to 8° of extension loss with standard management of simple elbow dislocations.
