Impingement syndrome of anterior ankle. Could be due to:
1) Anterior ankle osteophyte
2) Thickened synovium from previous ankle sprain (may progress to osteophyte)
3) End range of dorsiflexion activity (eg ballet dancing) may lead to osteophytes
Aching over anterior joint line – usually lateral; restricted dorsiflexion; anterior ankle is tender to palpation; may be able to palpate osteophytes; pain at end range of dorsiflexion.
Lateral weightbearing in dorsiflexion x-ray will show impingement
Activity modification; heel raise; surgical removal of osteophyte and/or irritated synovium (usually with arthroscope).
