2 Clinical Trials for Various Conditions
The study will be a non-blinded two cohort design consisting only of symptomatic patients with CuTS or compressive peroneal neuropathy or in need of peroneal nerve decompression. The first cohort will be - patients with CuTS. Evaluation of each CuTS patient will include assessment by the treating surgeon and a certified hand therapist. Patients who have clinical examination and history consistent with a diagnosis of CuTS based on subjective and functional assessment outlined below will be consented to this study. The second cohort will be patients in need PND for compressive neuropathy of peroneal nerve. PND patients will be evaluated by clinical exam and have imaging with high resolution ultrasound or MRI negative for mass lesion.
The goal of this clinical trial is to compare lidocaine without epinephrine to papaverine a known vasodilatory agent, in creating improved motor strength in patients with drop foot involving an entrapment of the Common Peroneal Nerve. This phenomenon has been named the Phoenix Sign and is a very specific peripheral nerve block. Researchers will compare the effects of the above agent for pre and post infiltration changes in motor strength. Participants will: * Will be randomized to one of either agents already listed * After receiving the ultrasound guided injection, motor testing will be evaluated in 4-6 minutes with manual motor strength testing of the anterior compartment muscles. * No additional follow will be required
