	'''Segond fracture''' refers to an avulsion fracture occurring on the lateral aspect of the [[tibial plateau]]. This distinctive injury involves a small bone fragment being pulled away from the main tibial structure, often due to forceful twisting or hyperextension of the knee joint. The Segond fracture is closely associated with tears of the [[anterior cruciate ligament]] ([[ACL]]) and is recognized as a reliable indicator of more significant ligamentous injuries.

	== Anatomy and Mechanism of Injury ==		== Anatomy and Mechanism of Injury ==
	The Segond fracture is believed to result from excessive tension applied to the [[anterolateral ligament]] ([[ALL]]), a structure connecting the lateral femoral condyle to the anterolateral tibia. Sudden force, as in sports or trauma, can cause the ALL to exert significant pull on the lateral tibial plateau, leading to the avulsion fracture. It commonly coexists with ACL tears, with up to 75-100% of Segond fractures occurring alongside ACL injuries. Additional injuries, like medial meniscal tears, may also be present.

	== Diagnosis ==		== Diagnosis ==
	Clinical diagnosis of a Segond fracture involves a thorough history and physical examination, complemented by imaging studies such as X-rays. X-rays typically reveal the characteristic avulsion fracture, though small fragments may not always be visible. In such cases, [[computed tomography]] (CT) scans or [[magnetic resonance imaging]] (MRI) can provide confirmation. MRI is particularly useful for assessing associated ligamentous injuries, including ACL tears.

	Treatment of Segond fractures depends on the injury's severity and concurrent ligamentous damage. Isolated fractures without significant instability may be managed conservatively with knee immobilization, rest, ice, compression, elevation (RICE), pain management, and physical therapy. In cases of associated ACL tears or significant instability, surgical intervention is often necessary. This may involve ACL reconstruction, fixation of the avulsion fracture, and repair or reconstruction of other injured ligaments.
