Filter by:The primary purpose of this study is to determine whether or not there is a correlation between MRI and ultrasound for the diagnosis of lower limb stress injuries. Patients that are seen at the University of Iowa Sports Medicine Center with a suspected diagnosis of a lower limb stress injury will be recruited. These patients will undergo a diagnostic ultrasound of the affected region prior to undergoing an MRI of that region. Then, the ultrasound findings will be compared to the MRI findings to determine if a correlation exists.
The purpose of this study is to determine the effects of a single dose of non-steroidal anti-inflammatory drugs on post-exercise markers of bone and muscle metabolism.
The main objective of this study is to find whether supplemental vitamin d and calcium can reduce the incidence of stress fractures in recruits. These high-risk recruits undergo intensive training which elevated bone turnover, which requires adequate level of vitamin D and calcium in order to support bone health. It is hypothesized that supplemental vitamin d and calcium will decrease the occurrence of stress fractures.
To test for a difference in the pharmacokinetics (PK) and pharmacodynamics (PD) of teriparatide (PTH 1-34), between healthy male and female volunteers matched to military recruits in training.
FORTEO (teriparatide [rDNA origin]; Eli-Lilly, Indiana, USA) is an injectable synthetic recombinant human parathyroid hormone analog that is commonly used to treat people with osteoporosis. In the current investigation this drug will be tested to evaluate its efficacy to accelerate bone healing and decrease the convalescence time of US Army Basic Trainees who have sustained a diaphyseal tibial stress fracture (DTSF). Investigators from the University of South Carolina will collaborate with military personnel to perform a prospective, randomized, double-blind, placebo-controlled study at Fort Jackson, SC.
A clinical trial will be conducted comparing healing of a posterior lumbar vertebra stress reaction in children treated either with cessation of sports activities for a period of six weeks and wearing a soft spinal brace 16 hours per day or cessation of sports activities only. Primary outcome is the change in stress reaction on MRI at 6 weeks compared to pre-treatment MRI.
Investigation into the use of teriparatide in the treatment of stress fractures. Primary outcome is healing on MRI, secondary outcomes are pain, time spent in rehabilitation and future stress fractures. This study will help the investigators understand how to treat stress fractures in the future.
The study will comprise of an original investigation that will take the form of a prospective intervention (two matched groups) study. Condition-1 will be a vitamin D supplementation group (50.000 IU every two months), and Condition-2 will be a placebo supplementation group. The primary research aim of this project is to evaluate the effectiveness of vitamin D supplementation to reduce stress fracture risk and susceptibility to skin, soft tissue infection (SSTI) and respiratory infection in Royal Marine recruits undertaking arduous physical training in a randomised control trial (RCT). The secondary research aims are: 1. To investigate whether supplementation of vitamin D3 at a dose of 50.000 IU every two months (equivalent to 800 IU per day) is effective in reducing the risk of stress fracture and susceptibility to skin, soft tissue and respiratory infection. 2. To examine changes in vitamin D status (relative to baseline serum 25(OH)D concentration), serum PTH concentration, and markers of bone turnover in response to vitamin D3 supplementation during the winter and summer months. 3. To identify interactions between dietary intakes, physical fitness, physical characteristics (body mass, BMI, thigh girth), smoking habit, alcohol consumption, and stress fracture prevalence with serum 25(OH)D status, serum PTH concentration and markers of bone turnover in the vitamin D3 supplemented group vs. the placebo supplemented group.
A clinical trial comparing healing of unilateral or bilateral spondylolysis in children treated with a Boston thoracolumbar orthosis (brace) or with a soft spinal brace (Porostrap lumbar support) for four months. Inclusion criteria will be a child or adolescent aged between 8 and 20 years with an early uni- or bilateral defect (fracture line) in the pars interarticularis in the CT-scan with no signs of bony sclerosis. Additionally, bone marrow edema has to be confirmed in MR images (T2 sagittal) as a sign of an early lesion. Exclusion criteria will be spondylolisthesis on standing spinal radiograph, systemic skeletal disorder or lack of interest. Patient's preference defines the treatment method. Minimum follow-up time will be 2 years for all patients. According to statistical power analysis a total of 60 patients will be needed to provide evidence for the effectiveness or no effectiveness of rigid thoracolumbar orthosis on the natural history of early spondylolysis. Measured outcome parameters are 1) Bony healing on CT-scan, 2) SRS-24-score at the beginning of the treatment and during the 2-year follow-up, 3) Back and lower extremity pain at the beginning of the treatment and during the 2-year follow-up (Pain drawing including VAS-score in children under 16 years old, Oswestry disability index including VAS-score in patients over 16 years old), 4) Thoracolumbar radiographs at 2-year follow-up: Evidence of spondylolisthesis, 5) Trunk strength and spinal mobility at follow-up visits. As part of this study, the investigators will also evaluate patients with spondylolysis treated in their hospitals before this clinical trial begun. In this retrospective study they will evaluate all patients between 8 and 20 years of age with spondylolysis, which have been treated with thoracolumbar orthosis after year 2009 and are not participating in to prospective study. Main focus will be in bony healing in CT-scans after brace treatment.
The main objective of this study is to find a correlation between vitamin D deficiency and stress fracture occurrences in athletes who participate in high-risk activities. These high-risk athletes undergo elevated bone turnover, which requires adequate levels of vitamin D in order to support bone health. It is hypothesized that providing supplemental treatment to athletes showing lower than normal serum vitamin D levels will decrease the occurrence of stress fractures. By recording the dates and specific occurrences of fractures, it may be possible to correlate injury rates with seasons, providing more supportive data to pre-existing literature. This area of research is lacking in the quantity of prospective studies. Previous studies primarily focus on adolescent, elder, or military recruit populations. While literature has shown that vitamin D plays an important role in bone health, there are no previous studies that directly examine vitamin D deficiency and supplemental treatment in conditioned collegiate athlete populations. This study will add to the existing knowledge and will provide a more specific analysis for athletes.
