UNNECESSARY SPINAL SURGERY
A PROSPECTIVE 1-YEAR STUDY OF ONE SURGEON'S EXPERIENCE
- Background: There are marked disparities in the frequency of spinal surgery performed within the United States over time, as well as across different geographic areas. One possible source of these disparities is the criteria for surgery.
- Methods: During a one-year period [November 2009-October 2010], the senior author, a neurosurgeon, saw 274 patients for cervical and lumbar spinal, office consultations. A patient was assigned to the "unnecessary surgery" group if they were told they needed spinal surgery by another surgeon, but exhibited pain alone without neurological deficits and without significant abnormal radiographic findings [dynamic X-rays, MR scans, and/or CT scans].
- Results: Of the 274 consults, 45 patients were told they needed surgery by outside surgeons, although their neurological and radiographic findings were not abnormal. An additional 2 patients were told they needed lumbar operations, when in fact the findings indicated a cervical operation was necessary. These 47 patients included 21 [23.1%] of 91 patients with cervical complaints, and 26 [14.2%] of 183 patients with lumbar complaints. The 21 planned cervical operations included 1-4 level anterior diskectomy/fusion [18 patients], laminectomies/fusions [2 patients], and a posterior cervical diskectomy [1 patient]. The 26 planned lumbar operations involved single/multilevel posterior lumbar interbody fusions: 1-level [13 patients], 2-levels [7 patients], 3-levels [3 patients], 4-levels [2 patients], and 5-levels [1 patient]. In 29 patients there were one or more overlapping comorbidities.
- Conclusions: During a one-year period, 47 [17.2%] of 274 spinal consultations seen by a single neurosurgeon were scheduled for "unnecessary surgery".
SOME COMMENTS BY READERS:
I have been practicing spinal surgery in Japan since 1980..... Through the communication with friends practicing neurosurgery in the US and with information from journals and meetings, I have noticed many different points in the rate and method of spinal surgery in the US and the other countries including Japan. As pointed out by the author, "unnecessary" spinal surgery was 17.2% in spinal consultation for the second opinion and overlapping comorbidities are as many as 29 out of 47 (62%). Significant increase of the rate of spinal surgery is attributed mainly to the development of diagnostic tools and operative techniques and implants in addition to increasing aged population in most countries [ (HERE & HERE) ]. However, the situation in the US seems to be a little bit different because of unusually high rate of spinal surgery. I am afraid that "unnecessary" spinal surgery and also "oversurgery" may be related to the money-oriented society which will subsequently jack up the medical costs and increase the rate of malpractice insurance. -Dr. Hiroshi Nakagawa.

Experienced and respected spinal surgeons regularly debate in conference forums how to manage specific cases. Disagreement on what to do, when to do it, and how to do it occurs more frequently than consensus. These debates highlight the deficiencies in our knowledge and understanding of degenerative, inflammatory, and mechanical spinal pathology. It is not surprising that the author came to a different conclusion in almost a fifth of the cases and it could be that a portion of these patients really could be managed with or without surgery. However, that cannot be true for all. The real message here is that there are surgeons recommending procedures without identifying the causative factor. Most of these procedures involved fusion which is more aggressive both biologically and economically as compared to nonoperative management or simple decompressions. Fusion was recommended for all of the lumbar procedures and half of these procedures were multilevel. The evidence supporting multilevel lumbar fusion for axial pain is very weak and even if the authors missed some cases of facet arthropathy this entity does not require a multilevel fusion. -Dr. Vincent C. Traynelis, Rush University Medical Center, Chicago, IL
This series includes psychiatric patients, cases without radiological precision and a predominance of "fusions" justified essentially on the notion of "instability" whose criteria are not established. The results of this kind of surgical procedure are poor with a significant morbidity leading to a therapeutic and financial higher bid. This article challenges: either the surgeons are inefficient or they are driven by commercialism. The first assumption seems unlikely considering that their technicality has been validated by various examinations and competitions. The second assumption can be retained. The US spent approximately $2.2 trillion on health care in 2007. Health care costs doubled from 1996 to 2006. The incidence of spinal fusion procedures increased from 60,973 cases in 1993 to 350,754 cases in 2007. -Gilbert Dechambenoit . Health Economist, Boulogne, France
Unnecessary --- A strong 'statement' - particularly if coming from one professional criticizing another. Although, I fundamentally agree with the principles addressed by the author, I question the validity of the methodology employed to justify such. Let's face it, we (Neurosurgeons) collectively do far too much spine surgery. The most challenging aspect of the 'unnecessary spine surgery discussion', however, is the clarification of the definition of 'unnecessary'. Unfortunately, what is 'unnecessary' to some, may be 'necessary' to others. -Dr. Edward Benzel. Chairman, Department of Neurosurgery, Cleveland Clinic
This paper is interesting in that virtually every neurosurgeon has had similar experiences to a greater or lesser degree. There are three reasons for unnecessary spinal fusions: greed, ignorance and stupidity. To illustrate this are situations that I have come across in my 46 years in practice. The big problem is greed. I hate to say it but most neurosurgeons want to do spine surgery because, at this time, it is lucrative. What is the solution - and there will be one. Either we solve the problem or the government will. I suggest that every hospital doing spine fusions establish a review committee to which the chart on every patient to be scheduled for fusion is reviewed to be sure that appropriate criteria are met. I suspect that this will reduce spine fusions by 20% or more. If we continue to ignore the problem then the government will step in, in a global fashion, by severely cutting the reimbursement for spinal fusion to the point that it will not pay to do that operation. Or worse, we will all be employees of the hospital or government. -Dr. Harold D. Portnoy. Director, The Hydrocephalus Clinic, St. Joseph Mercy, Pontiac, MI
