Abstract

INTRODUCTION:

The majority of patients with extremity sarcoma can be surgically treated without amputation. However, limb-salvage surgery for foot sarcomas including the calcaneus remains challenging.

PRESENTATION OF CASE:

A 71-year-old man presented with a 5-year history of right heel persistent pain. Imaging studies revealed an osteolytic, destructive and highly metabolic lesion in the right calcaneus. Computed tomography guided core needle biopsy confirmed the diagnosis of grade 2 chondrosarcoma. A total calcanectomy was performed, and the defect was reconstructed with a patient matched three-dimensional printed titanium calcaneal prosthesis. Intra-operatively, ligaments including the Achilles tendon, and plantar fascia were reattached. The post-operative course was uneventful, and at the 5-month clinical follow-up, the patient was fully weightbearing, with a mobile ankle without pain.

DISCUSSION:

This case is the first to use additive manufacturing to create a prosthetic calcaneus. The complex peri-calcaneal articular surfaces and reattachment of tendinous structures facilitate efforts to stabilize the prosthesis in situ.

CONCLUSION:

Three-dimensional-printed prosthesis of the calcaneus is a viable alternative to amputation.
