PURPOSE To evaluate factors predictive of recurrence following curettage of simple bone cysts (SBCs) in the proximal humerus. METHODS Records of 29 male and 3 female patients aged 3 to 22 (mean, 11) years who underwent curettage with or without bone grafting for a solitary SBC in the proximal humerus were reviewed. The appearance, size, location, activity level, and fracture pattern of each c...

Simple bone cysts are nonsymptomatic lesions. They typically involve the medullary cavity, but they can also be found in nonlong bones such as the calcaneum. Their treatment remains controversial varying from observation and conservative healing to irritating injections or bone grafting. In the case of a pathologic fracture, surgical treatment seems most appropriate especially when the cyst is ...

aneurysmal bone cyst (abc) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. treatment methods include surgical excision and curettage with or without bone grafting. we report a proximal femu...

aneurysmal bone cyst (abc) is a benign expansile bone tumor, most commonly involving the medulla of long bones. abc rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary abc changes, and telangiectatic osteosarcoma. both of these are sometimes mistaken micros...

although aneurysmal bone cysts and calcifying odontogenic cysts accompanied with other lesions are reported in the literature, the simultaneous occurrence of these two distinct lesions has not been reported. to the best of our knowledge, this is the first report describing co-occurrence of these two lesions located in the left mandibular ramusin a 36-year-old woman.

Introduction:Following the removal of cysts of the jaw, the resultant bone defect is filled or left unfilled depending on its size. There is, however, no universal standard defining the volume above which a bone defect should be filled. The objective of this study was therefore to determine a threshold for bone defect filling and to assess whether this threshold value can be used for preoperati...
