Planning CT with a CT biopsy grid in place. Evidence of hardware within the calcaneum which causes beam hardening artefact. Severe posterior subtalar joint arthropathy.

A 27G needle cannulates the posterior subtalar joint, with subsequent images confirming an intra-articular needle position and iodinated contrast spreading throughout it.
Case Discussion
End stage arthritis in the posterior subtalar joint can mean severe joint space loss, making guided intervention difficult. Fluoroscopy can be used but can very challenging in such cases and CT offers further identification of the joint space.
