Sumario: | INTRODUCTION AND IMPORTANCE: Pathologic fractures of the tibial tuberosity secondary to giant cell tumor of bone are rare injuries. While there are several well-described methods in the literature to reattach the tibial tuberosity, these techniques rely on good quality bone. However, in the presence of diseased and weak bone, additional factors have to be considered. CASE PRESENTATION: A 47-year-old man with a Giant Cell Tumor of bone affecting the proximal tibia presented with a displaced avulsion fracture of the tibial tuberosity. The patient underwent surgical curettage, bone grafting and osteosynthesis with reattachment of the tibial tuberosity. Eighteen months after surgery there is no evidence of tumor recurrence, and despite mild knee pain and a limited range of movement, the patient has returned to work. CLINICAL DISCUSSION: The extensor mechanism was repaired by first reinforcing the tuberosity fragment with an autograft before reattaching it using a tension band FibreWire ® suture. Without access to a tumor endoprosthesis we used a joint sparing approach to treat the Giant Cell Tumor. CONCLUSION: Patients with dual-pathology present technical challenges in repairing the extensor mechanism and treating the underlying condition. Surgeons must address competing priorities in a holistic, patient-centred approach consistent with their working environment. |
