Abstract:
An avulsion fracture occurs when soft tissues, including the tendons and ligaments, are forcibly detached from the main bone by an external force. The hand contains numerous anatomical structures, such as ligaments, tendons, and volar plates, which are essential for maintaining multidirectional motion and joint stability. Excessive force applied in a specific direction can damage these structures, leading to avulsion fractures around the joint. These fractures can result in severe complications if left untreated or improperly managed, including joint deformity, contracture, nonunion or malunion of the fracture, secondary osteoarthritis, and limited range of motion. Therefore, an accurate examination, diagnosis, and appropriate treatment are crucial for preventing these adverse outcomes. An avulsion fracture can be managed conservatively when the avulsed fragment does not compromise joint stability or motion. Nevertheless, surgical intervention is required to stabilize the fragment if it affects joint stability or motion. The use of internal fixation has become more prevalent because of recent advances in small implants for fixation.
