Introduction: Indications for surgical management of coccydynia are not well-defined in the medical literature. Furthermore, relatively high rates of local wound infection make coccygectomy a controversial procedure. Methods: The authors report two patients with favorable outcomes after surgical management of coccydynia, and suggest factors that may portend a positive response to coccygectomy. Results: The first patient suffered a pathologic coccygeal fracture from metastatic disease. The second presented with a displaced, mobile, chronic coccygeal fracture; this patient had derived significant but temporary benefit from focal injections performed by the Anesthesia Pain service. Both patients underwent coccygectomy and experienced excellent symptomatic relief postoperatively. Conclusion: The presence of imaging abnormalities of the coccyx, such as pathologic fractures and chronic non-union, and a positive response to focal injections are factors that likely predict a good outcome following coccygectomy.
