[Malleolar fractures. A statistical evaluation]

In a series of 67 displaced ankle fractures, the significance of the following factors is evaluated: age, sex, obesity, adequacy of the post-reduction position of the malleoli, restoration of distal tibio-fibular syndesmosis, talo-crural angle, talar tilt, width of medial clear space, severity of injury, traumatic mechanism, treatment. The statistical study is developed using stepwise discriminant analysis up to multiple linear regression. The significant parameters are the talo-crural angle, residual malleolar displacement, the integrity of the syndesmosis, and obesity. The discrimination is very good (p < 0.01).
