Ankle Ganglion Associated with Tarsal Coalition: A Case Report with a 5-Year Follow-up
1Department of Orthopaedic Surgery, Shriners Hospitals for Children Northern California, Sacramento, California.
Case:
Talocalcaneal coalition (TCC) is a common type of coalition, often neglected. This case is of a 10-year-old girl with a painful ankle mass, diagnosed with TCC and a ganglion cyst. Examination revealed stiff subtalar motion, a submalleolar prominence, and well-circumscribed, tender mass at the posteromedial ankle. Treatment options include short period of casting/observation, excision vs. aspiration of the cyst, resection of the TC coalition, or a combination of the above. She underwent TCC resection with cyst aspiration.
Conclusion:
At the 5-year follow-up, the patient's examination and imaging revealed normal motion without cyst recurrence, indicating resolution of the cyst with coalition resection.
