Distal Tibial Chondroblastoma With Intra-articular Penetration Treated With Gelatin Foam Sponge and Bone Grafting.


:A 14-year-old boy presented with sharp left ankle pain for 1.5 years. Evaluation showed an irregular lytic lesion with surrounding sclerosis (diameter, 1.3×1.2×1.1 cm) in the central part of the distal tibial epiphysis, extending from the physis to the plafond with articular penetration. Treatment included intralesional curettage and bone grafting through a mid-anterior epiphyseal bone tunnel with fluoroscopic guidance and use of a gelatin foam sponge to help contain the bone graft within the epiphyseal cavity. Microscopic examination of the excised tissue was consistent with chondroblastoma. Ankle arthroscopy 11 months later showed that the tibial plafond articular surface was fully healed. Two years postoperatively, the patient was asymptomatic and had no recurrence. This case shows that intralesional curettage and bone grafting, with a gelatin foam sponge to prevent graft extrusion, may be used successfully in treating distal tibial epiphyseal chondroblastoma that penetrates the ankle joint.
