Study Design Case series. Objectives To determine whether abnormal fibular alignment is
present in individuals with chronic ankle instability (CAI) using 3-D analysis of computed
tomography (CT)-based bone models. Background A positional difference of the distal fibula
in individuals with unilateral CAI, when compared to the contralateral side, has been
suggested. However, previous studies report no consistent pattern of fibular malalignment in
the anteroposterior direction and, to our knowledge, no study has investigated mediolateral …

Chronic ankle instability can be associated with ankle sprains and changes that occur at the
distal tibiofibular joint (DTFJ) with injuries. When there is increased movement at the DTFJ,
there is naturally an increase in talar movement, which affects the mechanics of the entire
foot. This change also affects the load distribution that occurs at the ankle during weight-
bearing and has been shown to lead to osteoarthritis of the ankle joint. 1 This increased
motion at the ankle is commonly assessed with radiography; however, computed …
