Résumé
Percutaneous vertebroplasty is a safe and effective procedure for the treatment of benign and malignant lesions of the spine, but has been associated with some known complications. Most complications are related to the percutaneous approach, but more severe complications related to the unwanted migration of acrylic cement can occur. We report an unusual case of a fatal pulmonary embolism caused by acrylic cement. Known factors related to cement leakage are incorrect needle position, the consistency of the cement, and the vascularity of the lesion. Emergency physicians should consider acute pulmonary embolism as a diagnosis when evaluating a patient who is suffering from dysnea or chest pain after an orthopedic procedure performed with cement.

PURPOSE: We had examined the effect of high dose MTX loaded acrylic cement in the treatment of type II collagen induced arthritis. MATERIALS AND METHODS: we used inbreed rat(16weeks - 20weeks) and divided into control group and experimental groups. inbreed rat was induced arthritis by prepared collagen through injection at the tail base. The control group was injected with collagen only. but the experimental groups were inserted intraperitoneally MTX-loaded acryl cement: 25mg, 20mg, 15mg, and 10mg MTX in acrylic cement (0.5gm) respectively. The histopathologic results were investigated to determine the effect of MTX on the 3rd, 7th, 14th, 28th, 42th, and 56th day after inserting high dose MTX loaded acrylic cement which was inserted intraperitoneally 2weeks later of collagenase injection RESULTS: The arthritis index of the MTX-loaded groups had reduced than arthritis index of the control group according to the dosage and In histopathological test, the experimental group injected with 15mg, 20mg, and 25mg of MTX had distinctive effects, compared to the control group, as dosage chronologically. CONCLUSION: The treatment of high-dose MTX loaded acrylic cement might be effective on rheumatoid arthritis managment.

3 cases of giant cell tumor in the distal femur or upper tibia were treated by curettage and acrylic cement packing between October 1978 and May 1981. All were females. The postoperative courses were satisfactory with no recurrence or malignant change for periods of 16 months to 30 months. In one case, acrylic cement reinforced with tantalum wire was used because it is superior to acrylic cement alone in mechanical properties. The adventages of this method are: 1. The cautery effect of setting cement. 2. Avoidence of the need for large quantities of cancellous bone 3. The possibility of incorporating a prosthesis if the lesion is extensive. 4. Rapid mobilization. 5. Ease of early diagnosis of recurrence.
