PURPOSE To determine whether the percentage of vertebral lesion filling and the leakage of methyl methacrylate have any clinical significance at follow-up. MATERIALS AND METHODS Forty percutaneous vertebroplasties were performed for metastases (30 cases) and myeloma (10 cases) in 37 patients. A computed tomographic scan was obtained 1-8 hours after methyl(More)
Vertebroplasty is an effective new radiologic procedure consisting of the percutaneous injection of a biomaterial, usually methyl methacrylate, into a lesion of a vertebral body. This technique allows marked or complete pain relief and bone strengthening in most cases. The principal indications for vertebroplasty are osteolytic metastasis and myeloma,(More)
The aim of this study was:to assess the long-term efficacy and safety of percutaneous vertebroplasty (PVP) for treating painful vertebral osteoporotic fractures, and to estimate the risk of vertebral fracture in the vicinity of a cemented vertebra. A prospective open study was conducted. PVP were carried out between July 1995 and September 2000 for 16(More)
OBJECTIVE To study the relationship between bone turnover markers and bone mineral density in patients with rheumatoid arthritis. METHODS We studied 54 patients, 24 of whom were receiving low dose steroids, and compared them to 54 age and sex matched controls. RESULTS An 8.2% decrease of femoral neck bone mineral density (BMD) was found in patients not(More)
The purpose of this cross-sectional study was to assess the extent of and mechanisms involved in bone loss in anorexia nervosa patients. We compared 113 anorexia nervosa patients (mean age 25 ± 8 years, mean duration of disease 5.7 ± 6.1 years) with 21 age-matched controls. Mean duration of amenorrhea was 3.2 ± 4.7 years. We measured serum calcium and(More)
Quantitative ultrasound (QUS) measurement, a different approach to bone fragility assessment, has already been attempted in women with osteoporosis but rarely in men. In order to test its value and ability to identify osteoporotic men, a case–control prospective study was conducted using the Lunar Achilles, a device that measures attenuation and velocity(More)
OBJECTIVES Percutaneous biopsy is widely used for the diagnosis of primary and secondary bone malignancies. The primary objective of this study was to evaluate the contribution of percutaneous biopsy to the definite diagnosis in patients with suspected bone tumor. The secondary objective was to assess the potential diagnostic benefits of a second(More)
We evaluated ultrasound propagation through the calcaneus using the Achilles Lunar unit in patients with postmenopausal or glucocorticoid-induced osteoporosis. Speed of sound, broadband ultrasound attenuation and a combination of these two parameters called stiffness were determined. Reproducibility was 0.23%, 2.6%, and 2.6% for these three parameters,(More)
OBJECTIVE To characterize the clinical, biological, and imaging features and outcomes of patients with streptococcal and enterococcal spondylodiscitis (SESD). METHODS This retrospective study of patients with SESD was carried out in 2 departments of rheumatology from 1990 through 2002. Comparison was made with cases of staphylococcal spondylodiscitis(More)
Animal experiments and studies in humans clearly show that the relation between pain (acute and chronic) and sleep quality is two-way: sleep disorders can increase pain, which in turn may cause sleep disorders. Sleep disorders and chronic low back pain are frequent health problems and it is unsurprising that the two can co-exist. This study was conducted to(More)
