Texas Back Institute Clinical Research
Pioneers for Advancing Spine Care
At Texas Back Institute (TBI), our physicians are dedicated to engaging in industry and physician-initiated studies and feel it is vital that discoveries translate into treatments and interventions that will improve the care for our patients.
Founded over 4 decades ago, our TBI physicians have proven their ability to keep up with patients’ varied needs, constantly adapting to remain at the forefront of innovated treatments that get our patients back to life. At TBI, we are committed to providing the highest quality treatments and services to our patients. One way we stay in the forefront of the latest advances in technology and treatment is through our clinical research program. With a dedicated research team, our patients receive benefit from some of the latest clinical spine studies, information gleaned from peer-reviewed research papers and the latest technology in motion-preserving procedures, minimally invasive procedures, and robotic technology for spine surgery.
Clinical studies at TBI help advance the field of spine care and patients gain access to technologies that often aren’t available to the public for several years. Our surgeons at TBI have been pioneers and champions in the advancement of spine surgery and are diverse in that we cover everything from trauma and deformity to tumors and the degenerative changes in the neck and spine that occur as part of the aging process.
Clinical studies involve patients and help doctors and researchers find new ways to improve treatments and the quality of life for people with spine disease, injury or deformity. In clinical studies, researchers methodically test drugs, medical devices, screening approaches, behavioral modifications and other interventions.
Clinical studies are used to answer many different clinical questions which can help you stay healthy and get better sooner. Participating in a clinical study at TBI can get you the most advanced treatment and help further spine research in our own community. Clinical studies are important for discovering new ways to detect, diagnose and treat spine conditions. Clinical studies can show researchers what does and doesn’t work and adds to overall medical knowledge to best treat the medical condition of patients.
Clinical studies vary from study to study but there are many similar benefits to participating in clinical studies:
- The potential of getting a newer and better treatment.
- Contributing to the advancement of medicine for a family member or friend and knowing that the knowledge gained by your participation may benefit others in the future.
- Getting the same high-quality treatment you would get with any treatment provided by TBI.
- Receiving additional care and attention from a research coordinator who works with the study doctor.
In order to participate in a clinical study, you must meet a strict set of criteria. These criteria are necessary in order to ensure you are the right patient for the study and to protect your safety. Your study doctor at TBI must always follow the study criteria for each specific study and must feel that in his/her medical opinion, you will benefit from the study treatment.
There are potential risks to participating in a clinical study. The risks may include:
- You may have to spend more time at your doctor’s office for research-related procedures and follow-ups which may not be required if you were not participating in a study.
- You may experience a side effect of the treatment.
- You may not receive any immediate benefit.
Your study doctor and study team will explain to you all the risks and benefits of participating in a study.
Your health and protection are our top priority. All studies are reviewed and approved by an Institutional Review Board (IRB). An IRB is a group of outside physicians, nurses, lay people and members of the community who are tasked with protecting all patients who consent to a clinical study. Studies are continuously monitored to ensure they are ethical and safe.
Before you can begin a clinical study, you will be asked to sign an informed consent form. This informed consent form is study-specific and will outline the clinical study and provide all the information we can give so that you can make an informed decision on your participation.
TBI is committed to providing the best possible care to you in an environment of innovation, research and education. TBI is truly unique in that they combine the expertise of fellowship-trained orthopedic surgeons and neurosurgeons who will work together to find the best treatment for you. Together, the research today may become the standard tomorrow.
Basic Science
The Spine Biomechanics Laboratory at Texas Back Institute exists to investigate the biomechanical and neuromuscular risk factors associated with spinal ailments in an effort to define the most appropriate and effective treatment options.
This lab is a critical component in bridging the basic science of biomechanics and engineering, with the clinical science of treating patients suffering from spinal ailments.
The clinicians and scientists involved with the lab are uncompromising in furthering the biomechanics related to the treatment of spinal pathology. They will make every effort to further the science and translate that knowledge into clinical advances which will benefit the patients we serve.
