Minimally invasive approaches such as sclerotherapy have been introduced to treat aneurysmal bone cysts. Sclerotherapy has been associated with reasonable healing rates during the past two decades. However, it is unclear whether sclerotherapy compares with the more traditional extended curettage and bone grafting. We therefore compared the healing rates and functional scores in patients having percutaneous repetitive sclerotherapy using polidocanol (Group 1) with those with intralesional excision (extended curettage with a high-speed burr) and bone grafting (Group 2) for treatment of aneurysmal bone cyst. We randomly divided 94 patients into two treatment groups. We assessed healing rates (primary outcome measure), pain relief, time to healing and recurrence, hospital stay, and the Enneking functional score. Forty-five patients from Group 1 and 46 from Group 2 were available for study. The minimum followup was 3.2 years (mean, 4.4 years; range, 3.2–6.1 years). At last followup, 93.3% in Group 1 and 84.8% in Group 2 had achieved healing. Complications in Group 1 were minor and resolved. In Group 2, three patients had deep infections and five had superficial infections, and two had growth disturbances. Although the healing rates were similar, we found higher rates of clinically important complications, worse functional outcomes, and higher hospital burden associated with intralesional excision. Repetitive sclerotherapy using polidocanol is a minimally invasive, safer method of treatment for aneurysmal bone cysts compared with intralesional excision and bone grafting. In this preliminary study, we found similar recurrence rates for the two treatment methods, however, this will require confirmation in larger studies. Level II, therapeutic study.

We present a 6-year-old child with a chondromyxoid fibroma (CMF) of the clavicle. In view of the atypical site, clinical features and imaging was not useful to pin point a diagnosis. The diagnosis was confirmed on histopathology. CMF is a rare benign bone tumor and only three cases of CMF clavicle are reported in world literature. Our patient is the first child reported with CMF of the clavicle. A very good result was obtained following an en-block resection of the clavicle. The report highlights the importance of keeping a diagnosis of CMF even at atypical sites like clavicle. [ABSTRACT FROM AUTHOR]

Abstract: Low grade central osteosarcoma is a rare primary bone tumor. This fibro-osseous lesion shares some radiological and histopathological resemblance with fibrous dysplasia, which is a more common entity. Thus it may be mistaken as fibrous dysplasia and may receive inadequate treatment resulting in a more malignant recurrent bone tumor. We present a case of low grade central osteosarcoma of the right tibia, which was initially treated as fibrous dysplasia with curettage and bone grafting. Three years later the tumor recurred with greater soft tissue and bony involvement but without metastasis. The patient was treated with above knee amputation and has been asymptomatic for the last two years. [Copyright &y& Elsevier]
