Case Reports
Successful treatment of aggressive aneurysmal bone cyst of the pelvis with serial embolization.
Intralesional surgery is most commonly used for aneurysmal bone cysts. Rarely is en bloc resection used for active, aggressive, recurrent lesions and those located in expendable bones. However, persistence or recurrence of aneurysmal bone cysts is common. ⋯ Six years after treatment, the patient was symptom free, and imaging showed complete ossification of the cyst. Selective catheterization and occlusion of the feeding arteries with the appropriate embolic agent provide tumor devascularization, size reduction, pain relief, and induction of new bone formation. Multiple procedures are often necessary, and complications may occur.

The association between hip fracture and reduced bone mineral density is well documented, with reduced bone mineral density predisposing to fracture. However, it is unknown whether an association exists between the magnitude of bone density lost and the severity of the hip fracture sustained. One hundred forty-two patients (96 women, 46 men) with a mean age of 74 years (range, 49-92 years) who sustained a hip fracture following a simple ground-level fall and were treated for this injury were reviewed. ⋯ Although a low hip bone mineral density (T- or Z score <2.5) was associated with an increased risk of extracapsular fracture (P=.025) compared with other fracture types, no association existed between bone mineral density and the severity of the resultant hip fracture. Although an association exists between bone mineral density and the risk of fragility fractures, the results of the current study suggest that the severity of hip fractures does not follow this correlation. Therefore, no assumption can be made about bone mineral density of the proximal femur based on the severity of the fracture observed on plain radiographs.

Bisphosphonates are a class of drugs that prevent bone loss by decreasing bone resorption. They represent a major treatment for osteoporosis and other metabolic bone diseases. Recent reports suggest that a potential complication of long-term bisphosphonate therapy may be atypical insufficiency fractures of the femur. ⋯ The literature currently recommends treating bisphosphonate fractures with an intramedullary nail. Perhaps initial treatment of these fractures should be similar to an atrophic nonunion, involving compression plating to obtain bone-on-bone contact and promote healing. This would address the biologic and mechanical etiologies of the bisphosphonate fracture.

Nonunion and secondary reduction loss complicate open distal femur fractures with bone loss. The authors hypothesized that locking plates decrease subsequent bone grafting yet maintain alignment and immediate postfixation radiographic features predict primary union. A retrospective chart/radiographic review was performed at a Level 1 university trauma center. ⋯ Thirty-four had accurate frontal plane reductions and 35 had accurate sagittal plane reductions. Despite metaphyseal bone loss, locking plates obviate the need for routine bone grafting of some open distal femur fractures. Those with radiographic posterior cortical contact are strongly correlated with primary union.

Every year, 4 billion pounds of waste are produced by health care facilities, and the amount continues to increase annually. In response, a movement toward greening health care has been building, with a particular focus on the operating room. Between 20% and 70% of health care waste originates from a hospital's operating room, and up to 90% of operating room waste is improperly sorted and sent for costly and unneeded hazardous waste processing. ⋯ Early review indicates that these changes are feasible, but a need exists for further evaluation of the effect on the operating room and flow of the surgical procedure and of the risks to the surgeons and operating room staff. Other key considerations are the effects of reprocessed and reused equipment on patient care and outcome and the role of surgeons in helping patients make informed decisions regarding surgical care. The goals of this study were to summarize the amount and types of waste produced in hospitals and operating rooms, highlight the methods of disposal used, review disposal methods that have been developed to reduce waste and improve recycling, and explore future developments in greening health care.
