The first known description of the coronal fracture of the lateral femoral condyle was published by Busch in 1869. Hoffa used Busch's drawing in the 1st edition of his book in 1888 and accompanied it with only one sentence.
A full case history of this fracture pattern was described by Braun in 1891. However, the Braun's article disappeared in oblivion and so the fracture was popularized only in 4th edition of the Hoffa's textbook, particularly thanks to the drawing, rather than the brief description.
Therefore, a fracture of the posterior femoral condyle, or more specifically, of the lateral condyle could properly be called "Busch-Hoffa fracture".
