Abandoned techniques in spine surgery

Abstract

In spine surgery, certain surgical techniques and devices are currently in marked decline or have been completely abandoned. Although used in thousands of patients, such treatments failed to demonstrate durable and sound effectiveness, and sometimes associate inacceptable morbidity. Chemopapain injections, percutaneous discectomy, laser discectomy or antiadhesion gels are examples of abandoned therapies. Some other techniques are in frank decline like implantation of interspinous devices or lumbar disc prosthesis. In general, a technique is abandoned due to inefficacy, excessive associated morbidity, substituted by another more efficacious and less aggressive technique, end of commercialization, or usage prohibition. In the last decades, a great commercial pressure plus an increasing social demand have managed to convince many spine surgeons to indicate treatments not sufficiently supported by scientific evidence nor consolidated over time, many of which are eventually abandoned.
