Effects of exosomes from mesenchymal stem cells on functional recovery of a patient with total radial nerve injury: A pilot study

Figure 1 Illustration of application. Sural nerve grafting was performed using 8-0 prolene to create four epineural sutures on each side. The subepineural route was used to microsurgically apply 0.25 mL of 1 mL exosome (containing 5 billion microparticles) to both sides of the proximal and distal stumps.

Figure 2 An intraoperative photograph. A gap of approximately 7 cm was observed in the injured radial nerve trace. Sural nerve graft was taken and repair of this gap was achieved with microsurgical technique. In the photograph, the light coloured part in the middle along the nerve line shows the sural nerve graft.
