Background: Chondroblastomas are benign tumors that typically occur in the epiphysis of long bones. Carpal bone chondroblastomas are very rare and are known to have less aggressive behavior with no evidence of recurrence reported. Methods: We present a case of a recurrent chondroblastoma in the capitate that was treated with repeat curettage, application of phenol, and bone grafting. Results: At 3 years post surgery, the patient is disease free with excellent functional return. Conclusion: Chondroblastomas are rare within the carpus. We present a review of the literature detailing their occurrence and treatment.

At the Mayo Clinic between 1950 and 1975, initial fusion of the interphalangeal joint of the great toe was attempted 166 times in 139 patients utilizing a Kirschner wire for stabilization. Follow-up examination of these patients disclosed an overall pseudarthrosis rate of 44%. Because of these disappointing results, a technique involving use of a longitudinal mini-cancellous bone screw was devised which provides increased stability and compression at the arthrodesis site. With this method, used 20 times in 18 patients, the pseudoarthrosis rate was decreased to 10%.

Angiomatoid fibrous histiocytoma (AFH) is a rare disease that is often misdiagnosed initially. Patients can present with a clinical picture concerning for other diseases, and pathologic review is not always revealing. Molecular diagnostics are increasingly being utilized to detect gene fusions characteristic for AFH. Surgery remains the mainstay of management, and can effectively control local recurrences and metastases. Herein we describe a case report of a 25-year-old gentleman whose presentation was concerning for lymphoma. Subsequently we review of the relevant literature.

Abstract Synovial chondromatosis of the shoulder has been treated in the past with an open arthrotomy, removal of loose bodies, and synovectomy. Several authors have described arthroscopy as a means of treating this rare disorder because of the excellent visualization of the glenohumeral joint, decreased morbidity, and early rehabilitation potential. This article offers a technique in which a large‐bore cannula and high pressure and flow are used to facilitate the removal of loose bodies from the joint.
