Investigating the CO2 laser for plantar digital neurectomy in horses.

The research analyzed the use of a carbon dioxide (CO2) laser for plantar digital neurectomy in horses and concluded that it is superior to conventional methods in preventing painful nerve growths known as neuromas.

Objective of the Study

• The primary aim of the research was to assess the effects of a CO2 laser on plantar digital nerves in horses.
• The study sought to determine the approproiate power density level of the CO2 laser that would yield the best tissue effects, particularly in preventing the formation of neuromas – painful nerve growths that can occur after neurectomy.

Methodology

• The researchers conducted a histological study (studying the tissues microscopically) on plantar digital nerve sections in horses that were cut with the CO2 laser.
• They made a series of nerve cuts using various power densities of the laser to observe the different tissue effects seen.

Findings

• From the study, it was observed that lower power densities of the CO2 laser appeared to provide the most beneficial tissue effects.
• The beneficial tissue effects were judged on increased thermal sealing of the proximal stump at the axon level, which is expected to prevent neuroma formation.

Conclusion

• The study concluded that the CO2 laser is superior to conventional instruments in preventing painful neuroma formation in horses after a neurectomy.
• These findings were based on the histological studies and on clinical observation and follow-up of horses that were subjected to laser neurectomy.
