Vascularized Bone Autograft for the Treatment of Chondroblastoma of the Talus at Imminent Risk of Joint Breakdown: Three Case Reports

Posterior ankle arthroscopic treatment of a talar chondroblastoma with allograft and a platelet-rich plasma-fibrin glue: A case report and literature review

Talar chondroblastoma, which is a benign tumor of immature cartilage cells, is an uncommon but easily missed diagnosis of foot pain. Arthroscopic treatment for this condition is a safe, powerful, and promising technique with definitive advantages of visualization and minimal invasion. Here, we report a case of a talar chondroblastoma treated by posterior ankle arthroscopic curettage, allograft bone graft, and platelet-rich plasma-fibrin glue (PRP-FG) application.

Benign and Malignant Tumors in Child Foot

Bone tumors affecting pediatric foot are a rare occurrence. Most lesions are benign, but a thorough diagnostic evaluation must always be performed to rule out malignant tumors. Approach to benign lesions is conservative, from observation follow-up to curettage or mininvasive techniques. In malignant lesions, a wide resection must be performed and same protocols applied as in tumors affecting other skeletal sites. Reconstructive procedures should aim to mechanical stability and long-lasting results; joint motion restoring can be attempted when not negatively affecting stability. Amputation procedures should be considered as a still viable choice because of their good functional result in the foot.
