Background
Who? Most commongly occurs in the active population following a sprain or repetitive micro-trauma at the extreme ranges of movement.
What? Chronic pain,
instability and limited range of movement.
How? Haemorrhage,
reactive synovial hyperplasia and scarring leading to abnormal soft tissue interposition within the joint.
Developmental or aquired bony spurs may also impede the normal range of movement.
Classification? This heterogenous group of pathologies is categorised according to the anatomical relation to the tibiotalar joint.
3 main types1...
- Anterior impingement,
which can be subdivided into anterolateral,
anteromedial and purely anterior impingement;
- Posterior impingement,
subdivided into posterior and posteromedial impingement.
- Extra-articular lateral hindfoot impingement,
which encompasses talocalcaneal and subfibular impingement secondary to a planovalgus foot deformity.
