Benign tumours and tumour-like conditions of the foot are not uncommon.
Primary bone tumours of the foot and ankle account for approximately 2-4% of all bone neoplasms and most commonly arise in the talus and calcaneus.
We provide an educational pictorial review of a range of tumours and tumour-like conditions of the talus treated in a tertiary referral centre for orthopaedic oncology.
Development and anatomy of the talus
The talus forms part of the hindfoot,
articulating with the tibia,
calcaneus and navicular.
Ossification of the talus originates from a single primary ossification centre,
formed between the 7thand 8thintrauterine month.
It possesses a head,
neck and body,
with approximately 60% of its surface being covered by articular cartilage (Fig. 1).
It has numerous ligamentous attachments but no muscular attachments.
It is supplied by the anterior tibial,
posterior tibial and peroneal arteries.
