The population-based prevalence of osteoporotic vertebral fracture and densitometric osteoporosis in postmenopausal women over 50 in Valencia, Spain …
2010
Purpose: To estimate the prevalence of vertebral fracture and densitometric osteoporosis in postmenopausal women over the age of 50 in Valencia, Spain. Methods: This cross-sectional study was conducted in 2006-2007. An age-stratified population-based random sample of 824 postmenopausal women over the age of 50 answered a questionnaire and received a densitometric examination of the lumbar spine and hip with dual-energy X-ray absorptiometry and a lateral X-ray of the thoracic spine and lumbar regions. Osteoporosis was defined as a T-score less than or equal to -2.5 compared to a population of young women, and the presence of vertebral fractures was classified according to Genant's semiquanti…
Ibandronate: a review of its vertebral and nonvertebral antifracture efficacy.
2009
After the Ibandronate Osteoporosis Vertebral Fracture Trial in North America and Europe (BONE) study had demonstrated the strong vertebral and nonvertebral antifracture efficacy of daily and intermittent oral ibandronate, the Monthly Oral Ibandronate In Ladies (MOBILE) study gave evidence for an increased efficacy on the bone mineral density (BMD) of higher intermittent oral ibandronate doses (150 mg monthly) compared with 2.5 mg daily. The BONE study also observed nonvertebral antifracture efficacy in patients with a high risk for fractures (mean femoral neck T score of −3.0 or less). A recently published meta-analysis assessing the nonvertebral antifracture efficacy corresponding to the …
Response of Bone Metabolism Markers to Ice Swimming in Regular Practitioners
2021
Objective: Both exercise and cold exposure cause physiological stress and they often occur in combination. However, the effects of exercise during severe cold on variation in bone metabolism in humans have remained elusive. The aim of this study was to investigate the variations in circulating bone metabolism markers after ice swimming (IS).Methods: Eighty-seven women and men aged 42–84 years old were recruited to perform regular IS activities. Serum parathyroid hormone (PTH), total calcium (Ca2+), total phosphorus (Pi), total magnesium (Mg2+), N-terminal osteocalcin (N-MID), total propeptide of procollagen 1 (TPINP), and C-terminal telopeptide of type 1 collagen (β-CTX) were measured 30 mi…
Duration of breastfeeding as a risk factor for vertebral fractures
2014
Abstract Purpose Among the risk factors for osteoporosis and fractures, gynecological history (fertile period, parity and breastfeeding) play an important part. Changes in calcium metabolism to enable an adequate mineral transfer to the milk have a prominent role in bone loss during breastfeeding. Data on the influence of breastfeeding in postmenopausal osteoporosis are inconsistent. The aim of the present study was to identify any association between duration of breastfeeding and vertebral fractures in postmenopausal women. Methods All patients underwent the following tests: bone mineral density measurements of the lumbar spine (L1–L4) and the total and femoral neck using dual-energy X-ray…
Is there still an indication for operative treatment of femoral neck fractures with a ceramic hemiprosthesis?
2000
From 1985 to 1995, 417 patients with dislocated medial femoral neck fractures (Garden III–IV) were treated with hemiarthroplasty using a Biolox ceramic head. The average patient age at the time of operation was 81.5 years. A total of 140 survivors was available for follow-up examination with a mean prosthesis longevity of 55.8 months. The Harris hip score recorded a mean of 70.6 points. At the time of follow up, 5 patients had severe hip pain, and in 8 the roentgenographic examination revealed protrusio acetabuli. Five of these 8 patients underwent revision surgery for replacement of the cup, leaving the stem in situ.
Langzeitergebnisse nach Versorgung medialer Schenkelhalsfrakturen mit Keramikkopfendoprothesen
1996
Total hip replacement is often recommended for the treatment of femoral neck fractures in elderly patients. A less invasive approach with shorter operating time is the replacement of the femoral head only, leaving the acetabular cartilage in situ. Hemiarthroplastic hip replacement using a metallic head prosthesis was not successful in the past, because the majority of patients developed protrusio acetabuli after surgery. In the present study hemiarthroplastic hip replacement using an Al2O3-ceramic head was shown to be a useful method for the treatment of femoral neck fractures in elderly patients. From 1985 to 1990 277 patients were treated with hemiarthroplasty. The average age at the time…
Improved femoral neck BMD in older Finnish women between 2002 and 2010.
2013
Abstract Purpose The number of hip fractures among Finns over 50-years of age rose constantly between 1970 and 1997, but since then, there has been a nationwide decline in incidence of hip fractures. One possible explanation, although not the only one, for the declining fracture rates, could be improved bone mineral density (BMD). The aim of this study was to evaluate differences in femoral neck BMD between older Finnish women born about a decade apart. Methods We compared the baseline data of two population-based samples of home-dwelling 70–80-year-old women who were initially recruited in exercise intervention studies ( N = 216 in Cohort1, and N = 389 in Cohort 2). Femoral neck BMD was …
Clinical performance of a highly portable, scanning calcaneal ultrasonometer.
2001
The aim of this study was to establish a normative database, assess precision, and evaluate the ability to identify women with low bone mass and to discriminate women with fracture from those without for a highly portable, scanning calcaneal ultrasonometer: the QUS-2. Fourteen hundred and one Caucasian women were recruited for the study. Among them were 794 healthy women 25–84 years of age evenly distributed per 10-year period to establish a normative database. Of these, 171 aged 25–34 years were defined as the young normal group for the purpose of T-score determination. Precision was assessed within 1 day (short-term) and over a 16-week period (long-term) in 79 women aged 25–84 years. Five…
Monitoring bone growth using quantitative ultrasound in comparison with DXA and pQCT.
2008
Quantitative ultrasound (QUS) is a safe, inexpensive, and nonradiation method for bone density assessment. QUS correlates with, and predicts fragility fractures comparable to, dual-energy X-ray absorptiometry (DXA)-derived bone mineral density (BMD) in postmenopausal women. However, its validity in monitoring bone growth in children is not well understood. Two hundred and fifty-eight 10-13 yr pubertal girls and 9 37-43 yr adults without diseases or history of medications known to affect bone metabolism were included in the 2-yr prospective study. Calcaneal broadband ultrasound attenuation (cBUA) was assessed using QUS-2 (Quidel, Santa Clara, CA), speed of sound of tibial shaft (tSOS) using …
Muscle strength characteristics and central bone mineral density in women with recent onset rheumatoid arthritis compared with healthy controls.
1999
Muscle strength and bone mineral density (BMD) at the lumbar spine (BMDspine) and femoral neck (BMDfem) were determined in 20 healthy women and in 20 women with recent onset rheumatoid arthritis (RA). The mean duration of articular symptoms of the patients was eleven months and none of them had used glucocorticoids or disease modifying antirheumatic drugs. BMDs were measured by dual x-ray absorptiometry (DXA). Knee extension, trunk extension, and flexion as well as grip strength were measured with David 200 and Digitest dynamometers. BMDspine (1.17 g/cm2 and 1.20 g/cm2) and BMDfem (0.98 g/cm2 and 0.96 g/cm2) between the women with early RA and healthy women did not differ. However, knee ext…
