Primary synovial chondromatosis of the talonavicular joint: A case report.
Synovial chondrometaplasia is an uncommon benign lesion most commonly affecting males in the 20 to 60 age range. The youngest heretofore reported patient is 14 years of age. In a male patient of 7 years, 2 months, with a bone age of 5 years with left elbow involvement, there was no history of antecedent trauma. The presenting complaint was enlargement of the elbow with limitation of motion. At surgery 54 osteocartilaginous bodies were removed, some of which were still covered with synovium. Eighteen months following an anterior synovectomy, there was 5 degrees to 128 degrees of pain-free elbow flexion and full painless forearm pronation and supination with no recurrence of the disease.
