Abstract Unicameral bone cysts (UBCs) of the calcaneus, although rare, can cause significant pain and deformity and are often missed on initial evaluation. In this case study, we present a 64-year-old male diagnosed with a calcaneal bone cyst causing pain to the right heel. Surgical intervention was deemed necessary due to persistent pain and functional impairment. The patient underwent excision of the calcaneal bone cyst via cortical windowing, curettage, application of phenol, grafting, and insertion of a fibular strut to maintain strength and stability of the calcaneus. No complications occurred and postoperative plain film radiographs confirmed adequate consolidation of bone defect with stabilization of calcaneus bone integrity. Postoperatively, the patient's pain resolved and he was able to bear weight in stable shoe gear once again. This case presents a comprehensive approach in the treatment of unicameral bone cysts to achieve successful outcomes and prevent fracture through the subtalar joint.
