98 Clinical Trials for Various Conditions
Determine if volume imaging can diagnose bone, ligament, muscle injuries.
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 purpose of this study is to compare two bone graft wound healing techniques; an open wound healing approach versus the standard closed wound healing approach.
The goal of this clinical trial is to compare photobiomodulation therapy (PBMT) in addition to standard of care in the treatment of tibial and metatarsal bone stress injuries in a military training setting. Participants will all receive usual care and also be randomized to either active or sham photobiomodulation therapy. Effectiveness will be assessed based on time to return to duty and measures of pain and function. * Participants will receive care for a maximum of 6 weeks. * Participants will have follow-up through 4 months (or graduation/dismissal from training, whichever comes first).
The goal of this study is to determine whether Vitamin D supplementation improves strength and bone density, and reduces the risk of injury in collegiate athletes.

Data analysis is underway.
The purpose of this study is to determine the effects of etanercept, and define the toxicity, when administered to patients with acute non-infectious lung injury (idiopathic pneumonia syndrome, IPS) and with subacute pulmonary dysfunction after allogeneic stem cell transplantation.
This multicenter prospective patient registry was developed with the aim of documenting how orthopedic surgeons are utilizing the NanoBone products in acute trauma cases along with relevant patient outcomes. These outcomes include radiographic measures such as fracture healing, instrumentation integrity, and clinical outcomes (symptom and function improvement) based on investigator and patient-based outcome assessments.
This is a double-blind, randomized, placebo-controlled trial of zoledronic acid, 5mg, to be administered intravenously to people who have suffered an acute spinal cord fracture. The goal is to evaluate if zoledronic acid can prevent the acute bone loss seen in this population. Outcome measures will include bone density determinations over a one year period.
Individuals with spinal cord injury sustain significant loss of bone mass in their lower extremities (20-40% or more). This study evaluates the ability of PTH and weight-bearing, two interventions that build bone, to increase bone mass in this population.
Neurogenic osteoporosis is a common complication of spinal cord injury (SCI) that is associated with low impact bone fractures. It is concerning that more than 46,000 Veterans affected with SCI and are at risk of osteoporosis and possible low impact fractures. About fifty percent of all individuals with SCI will develop low impact fracture in their life time. The management of osteoporosis-related fractures can impose substantial economic burden on the health care system, the individual and the families. Previous studies did not succeed in reversing the process of bone loss after SCI. In the present pilot study, we will evaluate the effect of Neuromuscular Electrical Stimulation Resistance Training in combination with oral Vitamin D supplementation, on bone quality in Veterans with chronic SCI, using a randomized experimental design.
The purpose of this pilot study is to explore whether dried plum (prunes) added to the diet is effective in reducing or reversing bone loss following spinal cord injury (SCI). The investigators will look for changes in bone mineral density as well as evidence in the blood of markers of bone activity. The first part of the study is to check whether participants with SCI can and will eat the required amount of dried plums (prunes) on a daily basis. The second part of the study is to follow participants over one year and look for changes in bone mass and blood markers.
Patients scheduled for major extremity lower amputation to receive bone marrow cells (cBMA) injected IM in the leg proximal to the amputation in the index limb to prevent ischemic wound complications after surgery.
This is a research study to determine the effects of functional electrical stimulation (FES) rowing and a drug called zoledronic acid in bone health. The investigators hoped to learn if zoledronic acid treatment will increase bone mineral density in persons with chronic spinal cord injury (SCI) who received it. The investigators also want to find out if zoledronic acid is safe for persons with SCI to take without causing too many side effects.
Guided bone regeneration (GBR) is a procedure used to increase the amount of bone volume in the jaw before placing a dental implant. It is needed when a lot of bone has been lost around the spot where a tooth has been lost or extracted. An incision is made, bone grafting material is placed in that spot, there is a membrane put over it as a barrier, then gum tissue has to be pulled back over it. Usually, this is enough to cover the whole wound, but sometimes the barrier membrane can't be covered with tissue the whole way without too much pulling, and the barrier membrane is still exposed. In that case, one thing that can be done is to place another material, an acellular collagen matrix, over the barrier membrane and secure it there. This material has been shown to help with the healing in these cases. Participants in this study will be clinic patients who have been determined to need a GBR procedure. Participants will get the GBR. If the barrier membrane is still exposed, then the acellular matrix material will be placed. This study will compare the healing outcomes and the success of the GBR depending on whether the acellular matrix material was used. The procedure itself is not part of the study. The only people in the study are patients who are already planning to have this procedure done as part of their dental care. It is important to note that the research study will not affect the care that the patient is given, or whether or not the acellular matrix material is used. That will be decided by the dental surgeon who is treating them, based on their clinical judgement. The research study will only observe and compare the outcomes. For the study, participants will have some additional clinical measurements made, besides the ones that are done as part of the follow-up care, and will be asked questions about their experience.
Traumatic injury followed by critical illness provokes pathophysiologic changes in the bone marrow and the gut that contribute to persistent anemia and changes in the microbiome which significantly impact long-term recovery. This project will define the interactions between the stress, chronic inflammation, bone marrow dysfunction, and an altered microbiome which will provide a strong foundation for future clinical interventions to help improve outcomes following severe trauma.
A prospective case series of 200 patients who have been treated with Bone Marrow Concentrate using anterior approach through posterior oropharynx for treating alar, accessory, and transverse injuries for patients with craniocervical junction instability.
Spinal cord injury (SCI) results in marked acute loss of bone. This study evaluates the effect of teriparatide (PTH) and the use of vibration as a form of mechanical stimulation on bone mass.
In persons with SCI, because of inherent considerations, the use of mechanical stimulation has not been studied to determine improvement in bone mass. To achieve maximum transmission of the vibration from a vibrating plate to the lower body, the legs must be extended and the feet firmly placed against the surface plate of the device. Thus, these logistical considerations must be addressed to perform this mechanical intervention in persons with SCI. In those with complete or almost complete motor injury, there is lack of musculoskeletal function below the level of the lesion, which would prevent rigid straight leg extension and pressing one's feet against a surface, regardless of the angle of tilt that would permit adequate transmission of impulse in an able-bodied individual (preliminary data). However, in one subject with SCI, there was measurable, albeit low level, transmission of vibration with increasing angles of tilt (preliminary data). Because of the ability to transmit some signal in an individual with complete SCI, the possibility exists that with forms or mechanical support/manipulation, greater signal transmission may be possible. The study will be able to determine the best angle to transmit mechanical vibration through the lower body of SCI patients.
This study will examine the relationship between circulating irisin and bone health individuals with spinal cord injury. Additionally, this study seeks to examine the influence of muscle fiber type on circulating irisin and identify an exercise-based means to increase irisin concentrations.
This pilot study will determine the feasibility of implementing a combinatory rehabilitation strategy involving testosterone replacement therapy (TRT) with locomotor training (LT; walking on a treadmill with assistance and overground walking) in men with testosterone deficiency and walking dysfunction after incomplete or complete spinal cord injury. The investigators hypothesize that LT+TRT treatment will improve muscle size and bone mineral density in men with low T and ambulatory dysfunction after incomplete or complete SCI, along with muscle fundtion and walking recovery in men with T low and ambulatory dysfunction ater incomplete SCI.
The purpose of this study is to determine if a year of alendronate treatment will maintain or increase bone mass density (BMD) compared to baseline BMD values in people with chronic spinal cord injury (SCI). This study will also investigate 1) if alendronate therapy will increase bone strength in people with chronic SCI, 2) the number of participants with adverse events from alendronate, and 3) the effects of alendronate on serum markers of bone metabolism.
The purpose of this study is to determine if a second year of exposure to teriparatide in both subjects that received a year of teriparatide or teriparatide-placebo will result in a greater increase in bone mass density (BMD) compared to that seen in a single year's treatment. This study will also investigate 1) if a second year of teriparatide therapy will increase bone strength in people with chronic spinal cord injury (SCI) who previously received a year of teriparatide or teriparatide-placebo, 2) the number of participants with adverse events from teriparatide, and 3) the effects of teriparatide on serum markers of bone metabolism.
All patients will be randomly assigned using a computer randomization algorithm to one of two matched cohort groups. Patients will not be advised which group they belong to until after the completion of the study. One group will be treated with autologous bone graft for bone patellar-tendon bone (BTB) Anterior Cruciate Ligament Reconstruction (ACLR), and the other group will be treated with commercially available DBM (Demineralized bone matrix) putty. Patients will be enrolled from Banner University. Before and after surgery, patient reported outcomes including visual analog pain scale (VAS), Tegner-Lysholm and Cincinnati ACL Test. The principal investigator will evaluate the patients on subjective criteria such as pain and objective criteria including range of motion, arthritic changes seen on radiographs, infection, and ability to kneel.
This study will examine whether using bone marrow aspirate (BMA) during knee arthroscopy surgery can improve patient outcomes. The investigators will enroll 50 patients who need knee arthroscopy surgery for meniscus injuries or cartilage damage. Like flipping a coin, patients will be randomly assigned to one of two groups of 25 patients each. One group will receive standard arthroscopic surgery plus an injection of bone marrow aspirate, while the other group will receive standard surgery plus a saline (salt water) injection. During surgery, for patients in the treatment group, approximately 4mL (less than one teaspoon) of bone marrow will be taken from their hip bone using a special needle system. A small amount (1mL) will be sent to the laboratory for testing. Patients will be followed for 12 months after surgery and will complete questionnaires about their pain levels and knee function at several time points: before surgery, 2 weeks, 6 weeks, 3 months, 6 months, and 12 months after surgery. These questionnaires will ask about pain, daily activities, and overall improvement.
The main purpose of the study is to measure and localize immediate post extraction changes i.e. socket expansion versus no width change along the socket wall and identify whether the immediate post-extraction ridge width condition (expansion or no change) is a determinant of buccolingual ridge width and height changes 4 months following extraction and ridge preservation.
The goal of this pilot randomized clinical trial is to look into the efficacy of concentrated bone marrow aspirate (cBMA) in improving post traumatic osteoarthritis (PTOA) symptoms in patients undergoing revision anterior cruciate ligament reconstruction surgery. The main questions it aims to answer are whether clinical outcomes, such as pain, are improved in patients who get cBMA with surgery, if there is a change in circulating markers of inflammation and what part of the cellular and molecular composition of cBMA may explain its effects.
Analgesic drug study that will compare pain outcomes of opioid analgesia and opioid-free analgesia in post-operative orthopedic patients.
Patients with Type 1 Diabetes Mellitus (T1DM) have a higher risk of low-trauma (osteoporotic) fracture that is 7-12 times higher than non-diabetics. The bone density of people with Type 1 Diabetes is higher at the time of fracture than in non-diabetics. This suggests the presence of underlying bone tissue mechanical defects. The potential benefits to participants would be knowledge gained about their bone density and the results of laboratory tests. On a wider scale, there may be general benefits to society because the knowledge gained from this study may help better understand the effects of diabetes on bone health
Serum lactate has been utilized as a standard in guiding management of orthopedic injuries. Elevated preoperative lactate has been associated with a higher likelihood of postoperative complications. However, lactate's role in guiding operative timing in non-critical long-bone fractures has not been previously explored. This study investigates lactate's role in guiding surgical timing and predicting complications secondary to delayed definitive correction in non-critical long-bone fractures with Injury Severity Score \<16.
