NCT04789044
The overall objective of this study is to determine the safety of PEG fusion when used with primary repair or reconstruction in patients with an acute upper extremity peripheral nerve injury. PEG is safe and effective for extending the half-life of circulating pharmaceutical products, when used in conjunction with a topical hemostatic agent in surgical wounds, and when used as a colon cleanser for endoscopic surgical procedures. However, PEG fusion has not been rigorously tested as a safe reagent to promote nerve regeneration in humans. Therefore, the goal of this Phase 2a clinical trial is to establish safety data and to examine the effect of PEG fusion on clinical outcomes including recovery of sensory and motor function. Results will be externally validated using data collected in the DoD funded prospective NERVE study and will provide preliminary evidence to power a larger phase II efficacy trial.
NCT01526681
This study is a registry of general use of Avance Nerve Graft and is intended to evaluate the uses, response rates, and safety of Avance Nerve Graft in the real-life clinical setting. Optional addendums 1 and 2 included in the protocol are intended to establish comparative groups and focused subgroups within the registry.
NCT07360730
This prospective multicentre observational registry evaluates early clinical outcomes following the use of High-Purity Type I Collagen (HPTC) as a circumferential nerve wrap during peripheral nerve procedures. Eligible procedures include nerve repair, coaptation, grafting, nerve transfers, and decompressions in the upper and lower limbs. Primary outcomes include early motor recovery assessed using the Medical Research Council (MRC) motor grading system. Secondary outcomes include sensory recovery, neuropathic pain, patient-reported functional outcomes, complication rates, and patient satisfaction assessed at standardized postoperative intervals up to two months.
NCT03999424
The purpose of this study is to assess the safety of autologous human Schwann cell (ahSC) augmentation of nerve autograft repair in participants with severe peripheral nerve injury (PNI). For humans with acute severe PNI, the hypothesis is that augmentation of nerve autograft repair with ahSCs can potentially enhance axonal regeneration and myelin repair and thus improve functional recovery.
NCT03913689
This Registry study will prospectively evaluate the long-term effectiveness, safety, and tolerability of the StimRouter Neuromodulation System, along with evaluating the technical performance of StimRouter, surgical outcomes, health-related quality of life, concomitant medical use, and subject's impression of improvement.
NCT02786888
Early ambulation after knee replacement surgery is made possible in large part by providing safe and effective pain control. Peripheral nerve blocks are increasingly used for postoperative analgesia since they can provide excellent pain relief and minimize the need for opioid analgesics. Ultrasound guided adductor canal block (ACB) was first reported in 2009 by anesthesiologists at the University of Utah. This block is unique in that it spares motor function in the lower extremity. Since 2009, a number of publications have described the successful use of ACB for pain management after total knee arthroplasty (TKA), anterior cruciate ligament (ACL) reconstruction, and other procedures of the knee. As a component of multi-modal analgesia, ACB can provide effective postoperative pain control and facilitate early hospital discharge. Although it is widely utilized, the ACB block can be technically difficult to perform since it requires injection in immediate proximity to the femoral artery and vein. In patients with a large thigh circumference, ultrasound can be challenging since the femoral vessels are deeper and more difficult to visualize. This presents the possibility of vessel trauma and/or intravascular injection of local anesthetic. The investigators have implemented a new technique for performing the ACB. This block is performed using a 20G fenestrated needle. The needle is FDA approved for peripheral nerve block. It has an occluded tip with 8 side ports on alternating sides of the distal 2cm. Injection through the fenestrated needle produces effective distribution of local anesthetic to nerves of the adductor canal without immediate proximity to the femoral artery and vein. The ultrasound landmarks used to perform ACB with the fenestrated needle are readily visible even in patients with very large thigh circumference. In summary, early experience with the US guided ACB block performed with a fenestrated block needle suggests that it is technically easier and potentially safer to perform than blocks performed with a conventional needle. This study should be performed prospectively in order to ensure accurate data comparing the two needles. A retrospective review of blocks performed using a conventional needle would not provide accurate data with respect to the number of attempts, time required to perform the blocks or the resulting sensory changes after performing the nerve block.

The implementation of early sensory re-education (SR) techniques, aimed to preserve the cortical hand area, such as the use of audio-tactile interaction, becomes an important strategy to obtain also a better sensory function. The aim of this study was to investigate sensory function outcomes (threshold monofilaments, two-point discrimination test, STI and DASH) and cortical responses (fMRI) in patients submitted to an early protocol of SR of the hand with a sensor glove model. After surgical repair of median and/or ulnar nerves, 17 participants were divided into two groups: the training group, trained on the protocol with the sensor glove model, and the control group, untrained. After six-month follow-up, no difference was observed between groups, related to sensory function, especially tactile gnosis. Despite this, the early training with this sensor glove model seems to provide some type of cortical audio-tactile interaction, contributing to previous studies that focus in early SR of the hand using the integration of different sensory modalities.
