Abandoned techniques in spine surgery.

Area of Science:

• Spine surgery
• Surgical technique evaluation
• Medical device assessment

Background:

• Several surgical techniques and devices in spine surgery have been abandoned or are declining.
• These treatments, despite widespread use, often lacked durable effectiveness and carried unacceptable morbidity.
• Examples include chemopapain injections, percutaneous/laser discectomy, and antiadhesion gels.

Purpose of the Study:

• To analyze the reasons behind the abandonment and decline of specific spine surgery techniques.
• To highlight the importance of evidence-based practice in spinal interventions.
• To discuss the impact of commercial pressure and social demand on surgical technique adoption.

Main Methods:

• Review of historical trends in spine surgery interventions.
• Analysis of factors contributing to technique abandonment (inefficacy, morbidity, commercialization).
• Examination of the role of scientific evidence versus market influence.

Main Results:

• Techniques like chemopapain injections and interspinous devices have been abandoned or declined due to poor outcomes.
• Reasons for abandonment include inefficacy, high morbidity, and replacement by superior alternatives.
• Commercial pressure has led to the adoption of inadequately supported treatments.

Conclusions:

• Spine surgery techniques require rigorous evaluation for efficacy and safety.
• Evidence-based medicine is crucial to prevent the adoption of ineffective or harmful procedures.
• Surgeons must critically assess new techniques, resisting commercial pressures in favor of patient well-being.
