[Percutaneous nucleotomy with discoscopy. 7 years' experience and results]

Area of Science:

• Orthopaedic Surgery
• Minimally Invasive Spine Procedures

Background:

• Percutaneous nucleotomy was pioneered in Japan in 1975.
• The University of Zürich introduced this technique in 1979 for lumbar disc herniation.
• Instrumental improvements and arthroscopic visualization (discoscopy) were implemented in 1982 for enhanced precision.

Observation:

• The study involved 75 patients undergoing percutaneous nucleotomy between 1979 and 1986.
• The procedure focused on the removal of nucleus pulposus under direct visual control.
• Refinements included improved instruments and the use of arthroscopes.

Findings:

• A significant clinical success rate was observed, with 65% of patients (48 out of 75) achieving excellent or good results.
• The 7-year experience with this surgical approach demonstrated its efficacy.

Implications:

• Percutaneous nucleotomy, particularly when enhanced with arthroscopic visualization, represents a valuable treatment for lumbar disc herniation.
• The findings support the long-term viability and effectiveness of this minimally invasive surgical technique.
• Further research can explore long-term outcomes and comparisons with other spinal interventions.
