Application of a Ni-Ti arched shape-memory connector in unstable lateral malleolus fractures: A retrospective study.

•ASC only fixation can serve as an effective means of managing Weber (AO) Type A or B lateral malleolus fractures.•ASC only fixation decreases wound and soft tissue complications, hardware complaints, and the incidence of additional surgery for revision or hardware removal.•With the distal extension of the fracture line, ASC only fixation is more applicable than lateral plate fixation.•For certain comminuted fracture patterns, the ASC can also be flexibly used for augmented fixation of a plate.
