US SPINE FUSION SURGERY DATA
A 2025 analysis of the PearlDiver all-payer claims database identified 1.2 million cervical spine surgeries performed between 2010 and 2022. Surgeons performed anterior cervical discectomy and fusion( ACDF) most often, accounting for 61.6 % of all cases( 774,913 surgeries), followed by decompressiononly procedures( 21.1 %), posterior cervical instrumented fusion( 14.0 %), and cervical disc arthroplasty( 3.4 %). Although ACDF continues to provide excellent clinical outcomes and remains a safe and effective treatment for many patients, surgical practice is changing. The annual number of ACDF procedures declined by nearly 15 %, while the use of alternative procedures, such as posterior cervical foraminotomy and cervical disc arthroplasty, has increased. One reason for the shift is that achieving successful fusion becomes more difficult as surgical complexity increases, particularly when multiple vertebral levels require treatment. Although ACDF remains highly effective, its limitations become more apparent in these complex cases. As a result, the growing cervical spine surgery market is expanding beyond ACDF alone, with increasing use of posterior and motion-preserving procedures that complement or, in some cases, replace traditional fusion. Similar trends appear in lumbar spine surgery. A 2026 cross-sectional study analyzed more than five million lumbar fusion admissions in the United States between 2002 and 2023. The study found that the age-adjusted rate of inpatient lumbar fusion increased from 60.1 per 100,000 population in 2002( 148,823 admissions) to 80.0 per 100,000 in 2023( 273,235 admissions). Surgeons increasingly used more complex procedures, especially combined anterior-posterior fusion techniques. Because spinal fusion is performed so frequently, even modest failure rates can create a substantial clinical and economic burden. Despite its widespread use, our understanding of outcomes after multilevel fusion remains limited, as much of the available evidence comes from a relatively small number of studies and relatively short follow-up times and qualitative measures. This highlights the need for high-quality clinical trials that provide the strongest evidence for evaluating treatment effectiveness.
Fusion grows more challenging
Patients undergoing single-level fusion surgery generally have excellent outcomes. Fusion rates exceeding 90 % are commonly achieved, and most patients experience significant improvements in pain, neurological function, and quality of life. However,
