Fibular + Medial malleolus + Posterior malleolus Anterior impingement
Definition
Impingement between anterior distal tibial osteophyte and sulcus of the talus in dorsiflexion
Epidemiology
Seen in athletes with repetitive dorsiflexion Football / soccer / ballet / gymnasts
Pathology
Anterior osteophytes Soft tissue impingement - scar tissue in anterolateral gutter from recurrent ankle sprains Bassett's ligament - thickened fascicle of the AITFL
Ankle ArthrodesisResults
90% fusion rates
Lose
Disadvantages of Arthrodesis
Non union rates up to 12% Decreased gait speed Poor mobility over uneven surfaces Ankle Arthroplasty
History
First generation (late 70s early 80s)
Results PVNSDefinition

Epidemiology
Age: 20 - 50 Sex: M > F
Types
