FDA clears CORUS™ PCSS for multilevel circumferential cervical fusion procedures based mostly on outcomes from the potential, multicenter, randomized, managed FUSE Examine
PLEASANTON, Calif., July 11, 2024 /PRNewswire/ — Windfall Medical Expertise publicizes FDA Clearance of its CORUS™ Posterior Cervical Stabilization System (PCSS) for the remedy of as much as 3-level cervical Degenerative Disc Illness (DDD). The FDA clearance was based mostly on outcomes from the FUSE IDE examine, a potential, multicenter, randomized managed trial evaluating security and effectiveness of Circumferential Cervical Fusion (CCF) versus Anterior Cervical Discectomy and Fusion (ACDF) alone in high-risk cervical fusion sufferers.
The FUSE Examine was carried out at 18 U.S. websites throughout 13 states and enrolled 227 sufferers aged 18 to 80, with symptomatic cervical DDD at three contiguous ranges. The examine randomized topics to obtain ACDF, the present commonplace of care, or CCF (ACDF plus posterior cervical fusion with the corporate’s PCSS expertise). Interim evaluation was carried out on over 200 topics at 1 12 months follow-up and 100 sufferers at 2 years follow-up.
The interim evaluation demonstrated the prevalence of CCF within the examine’s main endpoint of fusion success, highlighting the profound advantages of tissue-sparing CCF over ACDF alone:
- Superior Fusion Success at 1 12 months: The examine’s main endpoint demonstrated a 44.3% greater composite fusion charge of CCF over ACDF (61.0% vs 16.7%, p<0.001) utilizing a strict definition of composite fusion. Fusion was deemed a hit if all three consecutive ranges demonstrated movement of lower than 2 levels on flexion-extension radiographs and steady bridging bone was exhibited throughout the endplates of all three segments on thin-slice CT scans. Outcomes had been reported by an unbiased core imaging lab and verified by a number of radiologists.
- Dramatic Distinction in Revision Charges: Throughout all ACDF topics adopted via examine completion, 22.8% (13/57) required subsequent surgical intervention (primarily on account of symptomatic nonunion), in comparison with 1.7% (1/59) within the CCF arm.
- Total Security Success at 2 years: The examine’s secondary endpoint measured total security success at 2 years utilizing a composite of fusion success, lack of subsequent surgical interventions, upkeep or enchancment in neurological success, and Neck Incapacity Index (NDI) enchancment. The CCF arm exhibited a superior composite total security success charge at 24 months in comparison with the ACDF arm (CCF=50.8%, ACDF=22.8%, p<0.002).
- No Enhance in procedure-related Opposed Occasions: 3-level CCF with PCSS demonstrated statistically decrease procedure-related opposed occasions than 3-level ACDF (p=0.005).
These findings underscore the transformative potential of CCF with the PCSS gadget in managing degenerative disc illness in high-risk cervical fusion sufferers. With minimal added operative morbidity, CCF delivers vital enchancment to long-term outcomes over the present commonplace of care. As such, outcomes from this pivotal FUSE examine characterize a consequential development that redefines the usual of look after sufferers with multilevel illness.
Dr. Pierce D. Nunley, MD, the Director of the Backbone Institute of Louisiana and a Principal Investigator within the FUSE Examine, commented on the importance of the findings, stating, “The outcomes from this examine present very compelling proof for using circumferential cervical fusion with PCSS over the usual ACDF remedy for multilevel cervical degenerative disc illness. CCF sufferers had considerably greater fusion charges and better enhancements in patient-reported signs and total high quality of life. Moreover, the Secondary Surgical Intervention (SSI) charges show the sturdiness of CCF with PCSS: only one.7% of CCF topics (1/59) who accomplished the examine required SSI, in comparison with 22.8% of ACDF topics (13/57). This examine ought to trigger spine surgeons and payors to re-examine their most well-liked method to treating 3-level cervical DDD.”
Jeff Smith, Chief Govt Officer of Windfall Medical Expertise, remarked, “The findings from the FUSE examine mark a milestone in spinal surgical procedure. These outcomes unequivocally show that 3-level CCF with CORUS PCSS has superior efficacy for spinal fusion and that 3-level ACDF fusion charges are unacceptably low. The excessive charges of 3-level ACDF failures and reoperation underscore how these sufferers want extra to heal correctly and obtain optimistic outcomes. The power of this scientific proof means that CCF with CORUS PCSS ought to develop into the brand new commonplace of look after multilevel fusion sufferers.”

The FUSE Scientific Examine goals to redefine the usual of look after this prevalent situation via rigorous scientific inquiry and progressive remedy approaches. https://clinicaltrials.gov/examine/NCT04229017
Indications for Use:
CORUS™ Posterior Cervical Stabilization System (PCSS) is posterior spinal instrumentation with built-in screw fixation meant to offer immobilization and stabilization of spinal segments.
CORUS PCSS is positioned via a posterior surgical method in as much as 3 consecutive ranges of the cervical spine (C3-C7) and achieves bilateral aspect fixation by spanning the aspect interspace at every stage with factors of fixation at every finish of the assemble.
CORUS PCSS is meant as an adjunct to posterior cervical fusion (PCF) and is just meant for use together with an anterior cervical discectomy and fusion (ACDF) on the similar stage(s).
CORUS PCSS is indicated for skeletally mature sufferers with degenerative disc illness (DDD). DDD is outlined as radiculopathy and/or myelopathy, neck and/or arm ache of discogenic origin as confirmed by radiographic research.
CORUS PCSS is for use with autogenous bone and/or allogenic bone graft.
