Description
This is the rough crest of bone running down the posterior shaft of the femur in its middle third. It is a broad ridge of compact bone that serves as the site of attachment for many muscles and as a compressive strut for the shaft's anterior curvature. The vastus medialis, vastus lateralis, adductor brevis, adductor longus, adductor magnus, and short head of the biceps femoris muscles all attach to this landmark.
Etymology
This landmark derives its names from the Latin terms linea meaning line and aspera meaning rough.
