C1-C2 Intra-articular Screw Fixation for Atlantoaxial Subluxation Due to Rheumatoid Arthritis

Abstract

We read with interest the article “C1-C2 Intra-articular Screw Fixation for Atlantoaxial Subluxation Due to Rheumatoid Arthritis” (www.orthosupersite.com/view.asp?rID=37205) in the March 2009 issue of ORTHOPEDICS. The authors present a technique for the treatment of rheumatoid arthritis affecting the craniovertebral junction. They introduce an intra-articular spacer in the form of a screw and subsequently perform a posterior fixation by one of several available methods.

It is surprising that the authors could not locate any of our several published articles mentioning the use of intra-articular spacers. We have used intra-articular spacers in the treatment of basilar invagination, mobile and irreducible atlantoaxial dislocation, and rheumatoid arthritis.1-13 We first published the use of intra-articular spacers for rheumatoid arthritis-related craniovertebral instability in 2004.6,9 We did our first case of rheumatoid arthritis in November 2001.12 Over the years, we have used stainless steel, acrylic, and titanium spacers. We also reported the use of spiked titanium spacers that can stabilize the region by themselves so posterior fixation can be entirely avoided.

At best, the authors’ spacer is a modification of the spacer we described. The authors have unjustifiably not included our references on our technique of atlantoaxial fixation as well, despite the fact that they have used them in their patients.14,15

It is clear that the authors wish to make their spacer commercial and have deliberately avoided our publications. The present publication is against all scientific norms and a violation of the authenticity of published work.

We disagree with Professor Goel that our intra-articular screw fixation is an imitation of his procedure.

Our intra-articular screw fixation procedure was first published globally titled “C1-C2 Intra-articular Screw Fixation for Atlantoaxial Posterior Stabilization,” in the journal Spine in 2000.1 Furthermore, we presented this procedure at the 30th Annual Meeting of the Cervical Spine Research Society in Miami Beach, Florida, December 6, 2002.2

Our first case was a patient with rheumatoid arthritis in February 1995, and a preliminary report of our first series was published by a Japanese paper in 1996.3 The present article reports clinical results of patients with rheumatoid arthritis an average of 5 years and 1 month postoperatively.

Therefore, our idea came before the work of Professor Goel. Our only regret is that we did not confirm Professor Goel’s series of papers in 2004.
