Reconstruction of Digital Nerve Lesions With Muscle-in-Vein Conduits
Peripheral Nerve Injury Upper LimbMuscle-in-vein conduits (MVCs) provide an alternative for bridging digital nerve defects when tension-free suture is not possible. Low donor site morbidity and absence of additional costs are favorable advantages compared to autografts or conduits. 37 patients with 43 defects of proper palmar digital nerves were retrospectively enrolled. Primary repair by MVCs was performed in 22 cases while 21 underwent secondary reconstruction. Recovery of sensibility was assessed by static and moving two-point discrimination (2PDs, 2PDm) and Semmes-Weinstein monofilaments (SWM). Results were compared with contralateral side serving as intraindividual control. Outcome data were stratified according to international guidelines and evaluated for differences in terms of age, gap length, time of reconstruction and concomitant injuries.
Pain-related Evoked Potentials in Unilateral Peripheral Nerve Injuries
Peripheral Nerve InjuriesThe study examines pain-related evoked potentials (PREP) in patients with peripheral nerve injuries. Since previous studies found altered latencies and amplitudes of PREP in generalized polyneuropathies, e. g. HIV-polyneuropathy and fibromyalgia, this study investigates if these alterations are detectable in unilateral peripheral nerve injuries as well.

Peripheral Nerve InjuriesTo observe the Mid-term clinical effect of biodegradable conduit small gap tublization to repair peripheral nerve injury in multi-center.
NTX-001 to Repair Peripheral Nerve Transection(s)
Peripheral Nerve Injury Upper LimbThe proposed use of NTX-001 for transections of peripheral nerves in the upper extremity for subjects that don't qualify for study NTx20201.
Expanded Access - Autologous Human Schwann Cells in Peripheral Nerve Repair
Peripheral Nerve InjuriesEmergency expanded access for a single patient was granted to receive autologous human Schwann cell (ahSC) augmentation of nerve autograft repair after severe peripheral nerve injury (PNI).
Peripheral Physiological Measures as Determinants of Pain Risk
PolyneuropathiesPeripheral Nerve Injuries3 moreThis study evaluates peripheral nervous system function using Multiple Excitability Measures (MEM) to obtain "electrophysiological pain phenotypes"
Somatosensory Evoked Potential (SSEP) Monitoring for Detection of Intraoperative Positional Neuropraxia...
Peripheral Nerve InjuriesThoracic SurgeryPNI (Peripheral Nerve Injury) occurs in 5-15% of patients in cardiac surgery. So far, the mechanism of injury has never been researched. In this study, we will compare minimally invasive cardiac surgery with conventional cardiac surgery using a novel portable SSEP device to pinpoint the mechanism and timing of PNI during cardiac surgery.
Cortical Effects of Peripheral Nerve Injury At Birth
Peripheral Nerve InjuryCortical activity during rest and with stimulation by functional magnetic resonance imaging will be investigated in patients with OBPI.
Chronic Neuropathic Pain After Nerve Repair Hand Surgery
Peripheral Nerve InjuriesThis study intends to compare the patients with pain with those who underwent same procedure without developing pain. The patients with pain and without pain will be further analyzed in respect to clinical differences, biomarkers and genetical differences.
