Founded in 2008 by Steve Courtney, MD, and David Freehill, Eminent Spine’s product designs combine the spine surgeon’s medical expertise with an engineer’s design and manufacturing experience. The study included 158 patients who received 174 plates. The study demonstrates the Eminent Spine PEEK cervical cages are medically necessary for obtaining fusion. Here are five things to know about the white paper:
1. No patients needed a reoperation and there was no screw back-out, breakage, twister malrotation, twister popped off or plate breakage. The King Cobra can be used as an adjunct device to supplement anterior cervical fixation, according to the white paper, and the plate consists of titanium. The Copperhead PEEK cage system has multiple footprints to better fit the individual patient’s anatomy.
2. No patients reported Copperhead migration and there were no cage subsidence, migrations, fracture or collapse. The implant’s surface has a “teeth” pattern designed for good interdigitation with the bone immediately during surgery. There is not a titanium coating spray on the surface, which would increase implant cost.
“As we move fast forward in a cost conscious era, it is important to identify implants that are effective and minimize complications, especially in regard to revision surgery,” according to the white paper. “Eminent Spine’s system[s] decrease the cost of implant, not increase them.”
3. Among all patients who underwent surgery, there were no reports of dysphasia, infection or iliac crest morbidity. “The clinical based evidence paper utilizing Eminent Spine’s technique and implants provides overwhelming proof and evidence that PEEK cervical cages are not experimental and investigational,” according to the white paper. The paper continues to urge other spine surgeons and groups to share their personal data to validate efficacy and safety of their implants. “If we do not, no one will and spine surgeons will be forced to practice guideline medicine.”
4. The operating room time for King Cobra patients was 45 minutes to 230 minutes; 120 minutes on average. According to a study published in the Evidence-Based Spine-Care Journal, the average length of stay for patients after anterior cervical fusion was increased with older age, female patients and those with complications. Among the study’s 103 patients, the average length of stay was 1.98 days.
5. Estimated blood loss per patient was 12 cc to 400 cc; 100 cc on average. The patients treated include those who were smokers, had diabetes, previous pseudoarthrosis and HIV patients.
