We aim to describe our experience in the evaluation of talar lesions as a tertiary referral centre for orthopaedic oncology.
A series of tumours and tumour-like lesions are encountered in the talus.
This pictorial review provides a diagnostic approach for assessing these lesions.
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.
Imaging findings OR Procedure Details
A review of both the pathology and oncology databases at a tertiary referral centre for orthopaedic oncology was performed for patients with talar lesions.
histology and imaging features were recorded where available.
The site within the talus,
involvement of subchondral bone,
marrow and soft tissue oedema and fluid-fluid levels were recorded.
One hundred and twenty one patients with talar lesions were identified on our institutions databases with histopathological confirmation.
Patients with normal or nonspecific findings on...
As a tertiary referral centre for orthopaedic oncology,
we encounter a variety of tumours and tumour-like conditions of the talus.
The most common lesion encountered in our institution is chondroblastoma,
followed by osteoid osteoma.
The majority of lesions are benign,
malignant lesions are more common over the age of 30 years.
