■射频回波多光谱(REMS)是目前用于骨质疏松症的光密度评估的超声技术,并且已针对双能X射线吸收法进行了验证。然而,在严重运动和智力残疾(SMID)患者中使用REMS进行骨密度测定还有待报道.本研究旨在探讨REMS技术是否可用于SMID伴髋关节脱位和严重脊柱侧凸患者的骨密度评估。
■65名SMID患者,居住在长期护理机构并接受全面的医疗和康复护理,接受股骨颈和/或腰椎的REMS扫描。有关人体测量参数(身高和体重)的数据,骨矿物质密度(BMD),临床诊断分类,身体能力,脊柱侧凸和髋关节脱位的存在,并获得了两个髋关节的额叶X光片。
■我们包括29名男性和34名女性(平均年龄:52.6岁)。所有患者均在股骨颈(82.5%)或腰椎(95.2%)成功扫描。使用REMS获得的BMD测量值显示低值,平均BMD,T-score,Z评分为0.67g/cm2,-2.39标准偏差(SD),和-1.38标准差,分别,股骨颈和0.66g/cm2,-2.70SD,和-1.87SD,分别,腰椎。腰椎平均Cobb角为34.0°;在成功测量和未成功测量BMD的患者之间,脱位率没有显着差异(p=0.073)。腰椎BMDT评分与股骨颈BMDT评分显著相关(p<0.001,r=0.530)。
■所有患有SMID的患者都能够进行脊柱或股骨颈BMD的测量;此外,77.7%的患者在腰椎和股骨进行了测量。我们的数据表明,REMS可用于测量居住在机构中的SMID患者的BMD。
UNASSIGNED: Radiofrequency echographic multi-spectrometry (REMS) is an ultrasound technology currently used for the densitometric evaluation of osteoporosis and has been validated against dual-energy X-ray absorptiometry. However, the use of REMS for bone densitometry in patients with severe motor and intellectual disabilities (SMID) remains to be reported. This study aimed to investigate whether REMS technology can be used for densitometric evaluation of osteoporosis in patients with SMID with hip dislocation and severe scoliosis.
UNASSIGNED: Sixty-five patients with SMID, who resided in a long-term care facility and received comprehensive medical and rehabilitation care, underwent REMS scans of the femoral neck and/or lumbar spine. Data regarding anthropometric parameters (height and weight), bone mineral density (BMD), clinical diagnostic classification, physical ability, presence of scoliosis and hip dislocation, and frontal radiographs of both hip joints were obtained.
UNASSIGNED: We included 29 men and 34 women (mean age: 52.6 years). All patients underwent successful scanning at either the femoral neck (82.5 %) or lumbar spine (95.2 %). BMD measurements obtained using REMS revealed low values, with a mean BMD, T-score, and Z-score of 0.67 g/cm2, -2.39 standard deviation (SD), and - 1.38 SD, respectively, at the femoral neck and 0.66 g/cm2, -2.70 SD, and - 1.87 SD, respectively, at the lumbar spine. The average Cobb angle of the lumbar spine was 34.0°; furthermore, dislocation rates did not significantly differ between those with and without successful BMD measurements (p = 0.073). Lumbar BMD T-scores were significantly correlated with femoral neck BMD T-scores (p < 0.001, r = 0.530).
UNASSIGNED: All patients with SMID were able to undergo measurements of either spinal or femoral neck BMD; furthermore, 77.7 % of the patients underwent measurements at both the lumbar spine and femur. Our data suggest that REMS is useful for measuring BMD in patients with SMID who are residing in institutions.
