Objectives/Interrogation: To analyse the clinical features, imaging Characteristics, differential diagnosis, clinical treatment methods and The recurrence rate of aneurysmal bone cyst of the metacarpals and phalanges of the hand.

Methods: The clinical data of 12 cases of aneurysmal bone cyst of the metacarpals and phalanges from 2002 to 2012 was evaluated, and follow-up information was available. To review clinical symptoms and signs, X-ray and MRI imaging Characteristics, tumor performance, operative methods and bone graft, recurrence rate.

Results and Conclusions: 8 of 12 cases were in metacarpal, 4 of 12 were in phalange. The mean age was 28 years, 7 male and 5 female. Clinical features: Characteristics were local inflation and pain. Radiographs typically show a lytic lesion with expansion of the cortex. The lesion is usually well marginated and may have a faint sclerotic rim. MRI show a soap bubbIe like expensive bone destruction was detected. Bone trabecuIae mixed with osseous septae in the lesion and fluid-fluid level was detected. During operation bone contex became purple and swelling and thin. Treatment is by curettage and bone grafting and resection with reconstruction. 1 case recurrence. The diagnosos was clear by histopathology. 1 cases concurrent Giant cell tumors. Aneurysmal bone cyst of the metacarpals and phalanges of the hand is a infrequent disease, is not famillar to hand surgery surgeon. Early diagnosis is very difficult, should be differentiated from other hand bone tumors. Aneurysmal bone cyst of the metacarpals and phalanges of the hand have some identical clinical features and imaging characteristics, combination of X-rar and MRI can distinctly improve the correct ratio of the diagnosis. High-speed burr curettage and bone grafting and resection with reconstruction may reduce recurrence rate.
