Transected sciatic nerve repair by diode laser protein soldering.

Area of Science:

• Regenerative Medicine
• Biomedical Engineering
• Neurosurgery

Background:

• Peripheral nerve injuries (PNI) present ongoing challenges in regenerative medicine.
• Current standard treatment involves nerve suturing and anastomosis, with limitations in functional recovery.

Purpose of the Study:

• To compare the efficacy of diode laser protein soldering versus standard suturing for repairing transected sciatic nerves.
• To evaluate functional recovery and histological outcomes following different nerve repair techniques.

Main Methods:

• Adult male rats underwent sciatic nerve transection and immediate repair using either standard sutures or diode laser protein soldering.
• Functional recovery was assessed biweekly using the sciatic functional index.
• Electromyography (EMG) and histological evaluations were performed at 12 weeks post-surgery.

Main Results:

• Laser-assisted nerve repair was significantly faster than suture repair.
• The laser group demonstrated superior functional recovery based on the sciatic functional index (p<0.05).
• Histological analysis revealed improved epineurium recovery in the laser group (p<0.05) without increased inflammation.

Conclusions:

• Diode laser protein soldering is a more efficient and effective method for peripheral nerve repair compared to conventional suturing.
• This technique shows promise for enhancing nerve regeneration and functional outcomes in patients with nerve injuries.
