What is Fractura de Segond?

The Fractura de Segond is a specific type of avulsion fracture that occurs on the lateral side of the tibial plateau. It involves the detachment of a small bony fragment from the lateral tibial condyle, often due to excessive varus (inward) stress on the knee combined with internal rotation of the tibia. This fracture is frequently associated with injuries to the knee ligaments, particularly the anterior cruciate ligament (ACL), and can also be accompanied by meniscal tears.

Historical Perspective

First described by Dr. Paul Segond in 1879, this fracture has become a classic indicator in the medical field for assessing knee injuries. Dr. Segond's observations highlighted the correlation between this type of fracture and ligamentous injuries, paving the way for modern diagnostic techniques and treatment plans. The historical context of Fractura de Segond underscores its significance in orthopedic and sports medicine.

Importance in Diagnosis

The presence of a Fractura de Segond is a crucial diagnostic marker that alerts clinicians to the potential for additional knee injuries, specifically to the ACL. While the fracture itself may not cause significant pain or disability, it serves as a red flag for more complex knee trauma that requires comprehensive assessment and management.

Causes of Fractura de Segond

Fractura de Segond typically results from high-energy trauma to the knee, often occurring in sports that involve sudden pivoting or twisting motions. Common activities associated with this injury include soccer, basketball, skiing, and football. The fracture can also be caused by direct trauma to the knee, such as a fall or an automobile accident.

Biomechanical Factors

The mechanism of injury involves a combination of varus stress and internal rotation of the tibia, which places significant strain on the lateral structures of the knee. This stress can lead to the avulsion of the lateral tibial plateau, resulting in a Fractura de Segond. Understanding these biomechanical factors is crucial for developing prevention strategies and rehabilitation protocols.

Associated Injuries

Due to the nature of the forces involved, a Fractura de Segond is often associated with other knee injuries, most notably tears of the anterior cruciate ligament (ACL). Meniscal tears and injuries to the medial and lateral collateral ligaments are also common. Recognizing these associated injuries is essential for comprehensive treatment planning and achieving optimal recovery outcomes.

Symptoms and Signs

While the Fractura de Segond itself may not produce significant symptoms, it is often accompanied by other knee injuries that manifest through a range of clinical signs. These symptoms can vary depending on the severity of the injury and the extent of associated ligamentous damage.
