Spondylosis is an anatomical defect of the small facet joints between the spinal vertebrae often due to load bearing and mechanical wear. It is a major contributor to lower back pain. The current standard of care in patients diagnosed with spondylosis in the lower back is to perform a radiofrequency ablation (RFA) of the lumbar medial branch nerves which carry the pain signals from that region to the brain. RFA accomplishes this by using radio waves transmitted through inserted electrodes. This leads to a temporary lesion or "burn"; stopping the pain signals from being transmitted as as well as changing the pain signals themselves. The electrodes themselves do not heat up but instead cause ions in the surrounding tissue to vibrate and heat up. When performing the procedure at the UAMS pain clinic, one can use the Stryker system with a single electrode end which protrudes out of the cannula or the Stratus Nimbus electrode with two prongs which expand in a "V"; formation along the sides of the cannula. While testing in chicken tissue shows that the latter electrode type produces a larger lesion size, anecdotal evidence suggests that it may lead to longer term pain relief. As such, the choice is currently left up to physician preference as both are FDA approved for use in this condition. This study is trying to assess if the larger lesion size results in a reduction in impairment of activities of daily living due to pain measured by the patient-reported PROMIS (Patient Reported Measurement Information System)-29 questionnaire. The PROMIS-29 is given to all patients who are seen in the UAMS Pain Clinic at initial and follow-up visits. In this study we would like to randomize what electrode and cannula set is used in RFA for patient's who are already going to be receiving the procedure for treatment for their spondylosis. The study team would then compare the PROMIS outcomes between cases that used the Stryker and Stratus Nimbus electrodes at 1,3,6,9 and 12 months. It is hypothesized that the Nimbus electrode will result in a greater reduction and improvement in PROMIS scores for a longer duration than the Stryker electrode.
Spondylolysis, a stress fracture in the pars interarticularis of a lumbar vertebra, is the most common identifiable cause of low back pain (LBP) in adolescent athletes, occurring in 14-30% of athletes who experience LBP. Spondylolysis can cause significant pain and disability and months of exclusion from sports or an active lifestyle. Standard care of spondylolysis in adolescent athletes is primarily based on expert opinion, with dramatic variations in clinical practice, including restrictive bracing, extended rest periods before the intervention, long durations out of sport and activity, and suboptimal long-term clinical outcomes. As the next step towards our research goal, the overall objective of this pilot study is to perform a pilot randomized controlled trial to assess a novel rehabilitation strategy, the immediate functional progression program (IFPP), for treating active spondylolysis in adolescent athletes. Participants randomized to the IFPP group will begin physical therapy immediately (\<1 week) after diagnosis. In contrast, those in the standard care group (control) will not start physical therapy until their pain has resolved. Aim 1 will evaluate the effects of the IFPP on outcomes (Function, Pain, Quality of Life, and Edema on MRI) among adolescent athletes with an active spondylolysis. Aim 2 will assess the feasibility of performing a full randomized trial using the novel IFPP to treat athletes ages 10-19 with an active spondylolysis. Aim 3 will compare the tolerability of the IFPP to standard care. This pilot study will lay the necessary groundwork to perform a larger hypothesis-driven randomized controlled trial.
The objective of this clinical study is to compare OSTEOAMP SELECT Fibers to Infuse Bone Graft, in terms of effectiveness and safety, when used as a bone graft substitute in in skeletally mature patients qualified for 2-lumbar interbody fusion (LIF) by means of an intra-patient control model.
Opioid overuse is a widespread public health crisis in the United States with increasing rates of addiction and overdose deaths from prescription opioids. Reducing the need for opiate analgesics in the post-operative setting has become a high priority in minimizing long-term opioid use in surgical patients. This study will serve to demonstrate the efficacy of the addition of regional analgesic techniques in reducing post-operative opioid requirements in patients undergoing common lumbar spinal surgical procedures.
The purpose of this single-blind, randomized, controlled study is to assess the efficacy of "informative text messages" vs "traditional handouts" provided to lumbar spine surgery patients post-operatively.
This is a Pilot Study that is an open label, prospective, non-controlled study in which the safety and feasibility of Wharton's Jelly (WJ) allograft will be evaluated in 100 participants suffering with low back pain.
