P3: Role of PTH in enhancing fracture repair in aging (Clinical Trial)

本项目将调查特立帕帝(一种甲状旁腺激素的类似物)对加速的影响。 人体的骨折愈合过程。Teriparatide目前以Forteo的品牌名称销售 FDA批准用于治疗骨质疏松症。 我们的假设是，Teriparatide，凭借其刺激软骨细胞和 成骨细胞，会加速骨折愈合过程。要测量的骨折部位将是 骨盆。这将包括前柱和后柱、上支和下支的所有骨折以及 骶骨。受试者年龄将超过55岁，骨折将是由于低能量创伤造成的。 骨折愈合的评估将通过功能测试和骨痂的放射测量来进行。 量、疼痛评估和自我感觉功能。这项研究是一项前瞻性、双盲、 安慰剂对照试验。它将通过意向治疗分析进行分析。 在目标1中，我们将使用仪表化的坐立测试、计时起立测试和步态速度来 在康复过程中测量受试者的功能。我们还将对功能进行自我评估 问卷记录受试者对愈合的印象。在目标2中，我们将对愈伤组织体积进行量化 并监测疼痛程度、精神状态和抑郁的变化。 在这项试验结束时，我们将能够确定特立帕帝是否对功能性， 骨盆骨折愈合的生物学或主观幸福感方面。

This project will investigate the effects of teriparatide (an analog of parathyroid hormone) on accelerating the fracture healing process in humans. Teriparatide is currently marketed under the brand name Forteo and is FDA approved for the treatment of osteoporosis. Our hypothesis is that teriparatide, by virtue of its ability to stimulate recruitment of chondrogenic and osteogenic cells, will accelerate the fracture healing process. The fracture site to be measured will be the pelvis. This will include all fractures of the anterior and posterior columns, superior and inferior rami and the sacrum. Subjects will be over the age of 55 and the fracture will have been due to a low energy trauma. Evaluation of fracture healing will be by functional tests as well as radiographic measurements of callus volume, evaluation of pain and self-perceived function. The study is designed to be a prospective, doubleblind, placebo controlled trial. It will be analyzed with an intent-to-treat analysis. In Aim 1 we will use an instrumented sit-to-stand test, a timed-up-and-go test and gait velocity to measure subject function during healing. We will also administer a self-assessment of function questionnaire to document the subjects impression of the healing. In Aim 2 we will quantify callus volume and monitor changes in pain levels, mental status and depression. At the conclusion of this trial we will be able to determine if teriparatide has any effect on the functional, biological or subject well-being aspects of healing a pelvic fracture.
