Fractures of the Lateral Process of the Talus.

Lateral talar process fractures (LTPF) are uncommon injuries but have become more relevant with snowboarding. Currently the fractures are classified according to McCrory-Bladin into 3 types, with advice for treatment that is not ideal anymore. This article proposes modifying the existing classification by differentiating the multifragmented type III into 3 subtypes: IIIa, articular multifragmented but metaphyseal simple; IIIb, articular and metaphyseal multifragmented but reconstructable; and type IIIc, comminuted and nonreconstructable. A treatment-algorithm is presented. Undisplaced fractures are usually treated conservatively and displaced are an indication for surgery. In general, the outcome is good to excellent, if timely diagnosed and adequately treated.
