NCT04346680

Brief Summary

The goal of the investigator's observational, nonrandomized, open label study is to investigate the safety and efficacy of autologous adipose derived mesenchymal cells (ADSC) transplantation into the individuals with faiure in reconstruction of peripheral nerves. ADSC will be used during a last-chance surgery (neurolysis, nerve release) on a previously reconstructed nerve. All enrolled patients will have a documented at least 2-years clinical and electrophisiological observation. Each patient will recive once 10 microinjections of ADSC along the injured nerve, directly after nerve neurolysis. Safety, adverse events and efficacy will be confirmed by clinical, elecrophisiological (EMG, Sensory Thyreshold) and DASH survey.

Outcome Measures

Primary Outcomes (1)

  • Electrophysiological improvement

    Improvement in EMG - the appearance of activities in denervated muscles

    1 year

Study Arms (1)

Experimental group

EXPERIMENTAL
Procedure: ADSC administration

Interventions

The treated nerve will be identified and released. Scar tissue will be removed, and nerve fibers will be exposed. Prepared solutions of ADSC will be administered via microinjection with a 30-G needle along the released nerve fascicles, above and below the reconstructed area and around the adjacent tissue, which stayed in contact with the nerves.
