入选标准
- •Cervical disc disease defined as: intractable radiculopathy and/or myelopathy with at least one of the following items producing symptomatic nerve root and/or spinal cord compression which is documented by diagnostic imaging procedures:
- •herniated disc;
- •osteophyte formation;
- •decreased disc height;
- •thickening of ligamentous tissue;
- •disc degeneration; and/or
- •facet joint degeneration.
- •Has preoperative Neck Disability Index score >= 30;
- •C2-C3 disc to C7-Tl disc level(s) of involvement.
- •One or two adjacent levels requiring fusion;
- •No previous surgical intervention at the involved fusion level(s);
- •Unresponsive to nonoperative treatment for approximately six weeks or has the presence of progressive symptoms or signs of nerve root or spinal cord compression in face of continued nonoperative management;
- •Age > 18 years at time of surgery;
- •Is female of child-bearing potential, who is not pregnant or nursing, and who agrees to not get pregnant for 1 year following surgery;
- •Willingness to comply with study plan and sign the consent form.
排除标准
- •Has cervical spinal condition requiring surgical treatment other than symptomatic cervical disc disease at the involved level(s).
- •Has been previously diagnosed with osteopenia, osteoporosis, or osteomalacia to a degree that anterior plating would be contraindicated.
- •Has presence of spinal metastases.
- •Has overt or active bacterial infection, either local or systemic.
- •Has fever (temperature > 101°F oral) at the time of surgery.
- •Has a documented titanium alloy allergy or intolerance.
- •Is mentally incompetent. If questionable, obtain psychiatric consult.
- •Is a prisoner.
- •Is an alcohol and/or drug abuser as defined by currently undergoing treatment for alcohol and/or drug usage.
- •Has received drugs which may interfere with bone metabolism within two weeks prior to the planned date of spinal fusion surgery (e.g., steroids or methotrexate), excluding routine perioperative anti-inflammatory drugs.
- •Has a history of autoimmune disease (Systemic Lupus Erythematosus or Dermatomyositis).
- •Has a history of exposure to injectable collagen implants.
- •Has a history of hypersensitivity to protein pharmaceuticals (monoclonal antibodies or gamma globulins) or collagen.
- •Has received treatment with an investigational therapy within 28 days prior to implantation surgery or such treatment is planned during the 16 weeks following rhBMP-2/ACS implantation.
- •Has received any previous exposure to any/all BMP's of either human or animal extraction.
- •Has a history of allergy to bovine products or a history of anaphylaxis.
- •Has history of endocrine or metabolic disorder known to affect osteogenesis (e.g., Paget's disease, renal osteodystrophy, Ehlers- Danlos syndrome, or osteogenesis imperfecta).
- •Has a condition which requires postoperative medications that interfere with fusion, such as steroids, excluding routine perioperative anti-inflammatory drugs.
结局指标
主要结局
Neurological Status
时间窗: 24 month
Neurological status will be assessed preoperatively and postoperatively using a comprehensive neurological status scale.
Pain/Disability Status
时间窗: 24 month
The self-administered Neck Disability Index will be used. Success for each individual patient will be defined as pain/disability improvement postoperatively according to the following definition: Preoperative Score - Postoperative Score \>= 15
Fusion
时间窗: 24 month
Fusion is defined as: * No evidence of motion as defined by: less than 4° difference in angular motion between flexion and extension as seen on the lateral flexion/extension radiographs. * No radiolucency greater than 2mm of thickness covering more than 50% of superior or inferior graft surface. * Evidence of bridging trabecular bone.
次要结局
- Patient Satisfaction(24 month)
- Hip (Donor Site) Pain(24 month)
- Patient Global Perceived Effect(24 month)
- Time to fusion(24 month)
- General Health Status (SF-36)(24 month)
- Pain Status (neck pain, arm pain)(24 month)
