ABSTRACT
The term ``ankle impingement'' encompasses a broad range of conditions that are typically
post-traumatic and often chronic. Various forms of mechanical impingement can result
from synovial proliferation, bone spur formation, or ligamentous scarring and hypertrophy.
Since symptoms and physical findings can mimic a variety of disorders, accurate diagnosis
may remain elusive, and proper effective therapy may be delayed. The objective of
this article is to define and elucidate the etiology of the various forms of ankle
impingement, clarify the range of associated osseous and soft-tissue pathology, and
describe the imaging features and therapeutic options.
