Inexpensive Attachment Device for Cell Therapy Administration into Injured Spinal Cord.
BACKGROUND
Cell therapy is configured as a promising strategy for the treatment of spinal cord injury (SCI), but it requires reliable systems to achieve microinjections with different rates and volumes, according to the different characteristics of the injured spinal cord tissue and the targets previously selected.


OBJECTIVE
We sought to describe an original and inexpensive device for support of microinjection systems in the course of spinal cord surgery.


METHODS
Our attachment device consists of an arch and a system of bars that can be fixed to the operating table and on which a microinjection pump can be displaced and fixed in the course of surgery.


RESULTS
This device has been used for therapy administration into injured spinal cords. It is easy to use and permits reproducible results.


CONCLUSIONS
We have described an original attachment device for the support of a microinjection pump. It is applicable to spinal cord surgery and should be considered as a cheap solution for intralesional administration of cell therapy after spinal cord injury.
