“…Several nation-wide registration systems for spinal surgery have been established in Sweden (Swespine) (Strömqvist and Jönsson 1993;Jansson et al 2003Jansson et al , 2004Jansson et al , 2005Öhrn et al 2011;Strömqvist et al 2013;Fritzell et al 2015), in Norway (NORspine) (Solberg et al 2013;Fredø et al 2014;Grotle et al 2014), in Switzerland (SWISSspine) (Schluessmann et al 2009;Aghayev et al 2012;Hübschle et al 2014), in Turkey (Utku et al 2010) and United Kingdom (Breakwell et al 2015). Except Swespine since 1992, they have a relatively shorter history.…”

Spinal disorders affect mainly older people and cause pain, paralysis and/or deformities of the trunk and/or extremities, which could eventually disturb locomotive functions. For ensuring safe and high-quality treatment of spinal disorders, in 1987, the Tohoku University Spine Society (TUSS) was established by orthopedic departments in Tohoku University School of Medicine and its affiliated hospitals in and around Miyagi Prefecture. All spine surgeries have been enrolled in the TUSS Spine Registry since 1988. Using the data from this registration system between 1988 and 2012, we demonstrate here the longitudinal changes in surgical trends for spinal disorders in Japan that has rushed into the most advanced "aging society" in the world. In total, data on 56,744 surgeries were retrieved. The number of spinal surgeries has annually increased approximately 4-fold. There was a particular increase among patients aged ≥ 70 years and those aged ≥ 80 years, with a 20-to 90-fold increase. Nearly 90% of the spinal operations were performed for degenerative disorders, with their number increasing approximately 5-fold from 705 to 3,448. The most common disease for surgery was lumbar spinal stenosis (LSS) (35.9%), followed by lumbar disc herniation (27.7%) and cervical myelopathy (19.8%). In 2012, approximately half of the patients with LSS and cervical myelopathy were ≥ 70 years of age. In conclusion, the number of spinal operations markedly increased during the 25-year period, particularly among older patients. As Japan has a notably aged population, the present study could provide a near-future model for countries with aging population.

“…A complete documentation of a gold standard procedure like fusion in a national registry would need additional and substantial administrative and financial efforts, which were considered even less feasible. A cost-effective solution to this weakness is, e.g., a cross-registry comparison that has recently been undertaken for lumbar TDA in the SWISSspine and anterior interbody fusion in the Spine Tango registry [38]. A within registry benchmarking is also possible as this has been shown for lumbar TDA in the SWISSspine registry [39].…”

Background The Swiss Federal Office of Public Health demanded a nationwide HTA-registry for cervical total disc arthroplasty (TDA), to decide about its reimbursement. The goal of the SWISSspine registry is to generate evidence about the safety and efficiency of cervical TDA. Materials and methods Three hundred thirty-two cases treated between 3.2005 and 6.2006 who were eligible for 5 years follow-ups were included in the study. Follow-up rates for 3-6 months, 1, 2 and 5 years were 84.6, 74.4, 50.6 and 64.8 %, respectively. Outcome measures were neck and arm pain, medication, quality of life, intraoperative and postoperative complication and revision rates. In addition, segmental mobility, ossification, adjacent and distant segment degeneration were analyzed at the 5-year follow-up. Results There was significant, clinically relevant and lasting reduction of neck (preop/postop 60/21 VAS points) and arm pain (preop/postop VAS 67/17) and a consequently decreased analgesics consumption and quality of life improvement (preop/postop 0.39/0.82 EQ-5D points) until the 5-year follow-up. The rates for intraoperative and early postoperative complications were 0.6 and 7.2 %, respectively. In 0.6 % an early and in 3.9 % a late revision surgery was performed. At the 5-year follow-up, the average range of motion of the mobile segments (88.2 %) was 10.2°. In 40.7 % of the patients osteophytes at least potentially affecting range of motion were seen. Conclusions Cervical TDA appeared as safe and efficient in long-term pain alleviation, consequent reduction of pain killer consumption and in improvement of quality of life. The improvement is stable over the 5 years postoperative period. The vast majority of treated segments remained mobile after 5 years, although 40.7 % of patients showed osteophytes.

“…3 The true comparator for the lumbar TDR is regarded to be anterior lumbar interbody fusion (ALIF) due to the similar surgical approach to the vertebral column and the solely anterior rigid or dynamic stabilization of the respective spinal segments. 4 New generation disc implants attempt to better mimic the viscoelastic function of the natural discs with potentially more patient benefits in comparison to the "hard" first generation disc implants. They have been developed and introduced into clinical practice in recent years.…”

“…5 Comparative effectiveness studies of different fusion types and TDRs are extremely rare today. 4 Randomized clinical trials (RCT) comparing fusion and TDR are rare and have a high administrative burden. 2 Wei et al found six such RCTs in their meta-analysis, whereas only two trials used ALIF as comparator.…”

“…17 A recent matched comparison of pain alleviation of all lumbar TDRs in the SWISSspine registry with ALIF cases from the Spine Tango registry showed similar results. 4 The 5-year results of 248 lumbar TDRs in the SWISSspine registry showed significant and longlasting back and leg pain relief from 7.2 and 5.5 Visual Analog Scale (VAS) points preoperative to 2.8 and 2.2 points postoperative at the fifth postoperative year. 13 It should be noted that the implants used in this study were implanted in the years 2005 and 2006 and still represent the first generation of lumbar disc arthroplasties.…”
