Robot-assisted C7 nerve root transfer from the contralateral healthy side: A preliminary cadaver study

Area of Science:

• Neurosurgery
• Robotic Surgery
• Rehabilitation Medicine

Background:

• Patients with cerebral palsy and spastic hemiplegia often exhibit severe upper extremity dysfunction.
• Current treatments for spastic hemiplegia yield limited functional improvements.
• Contralateral C7 nerve root transfer is an innovative technique to improve motor control and reduce spasticity.

Purpose of the Study:

• To evaluate the feasibility of a minimally invasive, robot-assisted contralateral C7 nerve root transfer.
• To assess the potential of this technique to overcome limitations of traditional open procedures.

Main Methods:

• Dissection of both C7 nerve roots in a cadaver model.
• Proximal resection of the recipient C7 root and distal resection of the donor C7 root.
• Utilization of the da Vinci SI surgical robot for the nerve transfer procedure.

Main Results:

• The robot-assisted technique successfully eliminated the need for large incisions.
• A significantly shorter nerve graft was required compared to traditional methods.
• Demonstrated feasibility of a minimally invasive approach for contralateral C7 nerve transfer.

Conclusions:

• Minimally invasive, robot-assisted contralateral C7 nerve transfer is a feasible technique.
• This approach offers advantages by reducing incision size and nerve graft length.
• Potential for improved outcomes in patients with spastic hemiplegia due to enhanced neurotization.
