Journal of Orthopaedic Surgery and Research 2010 5 79 http content 5 1 79 JOURNAL OF ORTHOPAEDIC SURGERY AND RESEARCH CASE REPORT Open Access Unicameral bone cyst of the lunate in an adult case report Hakan Gundef Mustafa Sahin Tugrul Alici Abstract We report a case of a symptomatic unicameral simple bone cyst of the lunate in a 42-year- old woman. The lesion was treated with curettage and cancellous autogenous iliac bone grafting. At five years of follow-up the wrist was pain free there were no limitations of motion and the radiographs showed complete obliteration of the cavity. To the best of our knowledge no other unicameral bone cyst of the lunate has been reported in an adult. Cysts with significant cavities at the carpal bones in an adult should be approached cautiously as they may require early curettage and bone grafting for healing before collapse and degenerative changes occur. Background Unicameral bone cysts UBCs also known as simple bone cysts are benign fluid-filled lesions involving the metaphysis of long bones 1-3 . On radiography they demonstrate a centrally located lytic lesion with well-defined margins 2 . The cyst wall is lined with a fibrous membrane which contains serous yellow fluid 2 . 80 of UBCs occur in the proximal humerus and proximal femur 1 3 . Most UBCs occur in childhood where one third of the cases will resolve spontaneously by skeletal maturity 1-3 . Occurrence of a single symptomatic radiolucent lesion in the lunate is rare 4 5 . A differential diagnosis of a painful radiolucent lesion in the lunate would include intraosseous ganglion Kienbock s disease osteoid osteoma giant cell tumor aneurysmal bone cyst and enchondroma 4-9 . The incidence of UBCs involving the wrist bones and lunate has not been clearly defined in the literature 10 . Case presentation A 42-year-old woman was referred to the hand clinic with dull pain and discomfort in her right dominant wrist that had been present for six .
