Evaluation of Bone Cement Augmentation in Proximal Femur
نویسندگان
چکیده
The prevalence of bone fractures increases markedly with age, which is correlated to osteoporosis, low bone mass and structural deterioration of trabecular bone. Infiltration of bone cement into vertebral bodies (vertebroplasty) has been shown to substantially increase the strength and stiffness of mechanically compromised trabecular bone. It was expected that a similar benefit might be realized in the proximal femur [Heini, et al, 2001]. Before clinical trails, the effects of this treatment technique should be investigated. The objective of this study was to investigate the effects of cement augmentation on the mechanical properties of the proximal femur. In the present paper, the relative effects of bone osteoporosis, femoral neck fracture and cement augmentation on the femur stiffness were evaluated using finite element simulations.

متن کاملThe PFNA® Augmented in Revision Surgery of Proximal Femur Fractures
OBJECTIVES Modern implants for proximal femur fracture treatment have clearly improved clinical results. However, complications, including cut-out and loss of reduction, requiring revision surgery still occur. A major challenge in these cases is a loss of bone stock due to the existing implant, which is usually exacerbated by osteoporosis. A potential solution is the augmentation of implants, f...
متن کاملIntramedullary nailing without curettage and cement augmentation for the treatment of impending and complete pathological fractures of the proximal or midshaft femur.
Metastases in the proximal femur and in the femoral diaphysis are usually treated with either cephalomedullary or intramedullary nailing. The benefit of curettage and augmentation of the nail with methyl methacrylate remains controversial. The authors retrospectively studied the outcomes with cephalomedullary and intramedullary nailing without curettage and methyl-methacrylate augmentation for ...

Giant cell tumor (GCT) is a primary and benign tumor of bone, albeit locally aggressive in some cases, such as in the epi-metaphyseal region of long bones, predominantly the distal end of femur and proximal end of tibia (1). There are a variety of treatments for a bone affected by GCT, ranging from chemotherapy, radiotherapy, embolization, and cryosurgery, to surgery with the use of chemical or...

Osteoporotic hip fracture is the most severe kind of fracture with high morbidity and mortality. Patients' ambulation and quality of life are significantly affected by the fracture because only 50% regain their prefracture functional status, even if they undergo surgeries. There are many issues associated with the current preventive methods e.g., cost, side effects, patient compliance, and time...
