Our latest paper, co-authored with my previous registrar @scott_rb , has been published in the Annals of the The @royalcollegeofsurgeons .
The paper examines the evolution of our understanding of posterior malleolar fractures, from JG Bonnin’s original cadaveric experiments to contemporary CT-based classification.
His experiments 75 years ago, demonstrated that an axially loaded, rotating talus could act as a wedge within the ankle mortise, producing a rotational pilon-type fracture (the Mason and Molloy type 2). He also recognised that the resulting damage to the tibial plafond, rather than simply the size of the posterior fragment, was important in determining prognosis.
