入选标准

  • Has degenerative disc disease as noted by back pain of discogenic origin with degeneration of the disc confirmed by radiographic studies.
  • Has no greater than Grade 1 spondylolisthesis utilizing Meyerding's Classification (Meyerding HW, 1932.)
  • Has single level symptomatic degenerative involvement from L2 to S
  • Is between the ages of 18 and 65, inclusive, at the time of surgery.
  • Is willing to comply with the study plan and sign the Patient Informed Consent Form.
  • Has not responded to conservative treatment for a period of 5 months.
  • If of child-bearing potential, subject is non-pregnant (documented by a negative Pregnancy test within 72 hours of surgery), non-nursing female who agrees to use adequate contraception for 16 weeks following surgery

排除标准

  • Has spinal condition other than symptomatic degenerative disc disease at the involved surgical level.
  • Had previous anterior surgical procedures at the involved spinal level.
  • Has a condition which requires postoperative medications that interfere with fusion such as steroids or nonsteroidal anti-inflammatory drugs. (This does not include low dose aspirin for prophylactic anticoagulation.)
  • Has osteopenia, osteoporosis, or osteomalacia to a degree that spinal instrumentation would be contraindicated.
  • Has circulatory problems, such as thrombophlebitis, lymphedema, or vascular deficiency at the implant site.
  • Has symptomatic cardiac disease.
  • Has presence of active malignancy or history of cancer in the past 5 years.
  • Has overt or active infection.
  • Is obese, i.e., weight greater than 40% over ideal for their age and height.
  • Has fever (temperature > 101°F oral).
  • Has local inflammatory signs indicative of infection.
  • Has a documented metal allergy or intolerance.
  • Is involved in a worker's compensation or unresolved spinal litigation case.
  • Is mentally incompetent (either documented or in the opinion of the investigator).
  • Has psychogenic magnification of pain (in the opinion of the investigator).
  • Is a prisoner.
  • Is pregnant.
  • Is an alcohol and/or substance abuser.
  • Requires bone growth stimulation in the lumbar spine.
  • Is a tobacco user at the time of surgery.
  • Patient 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).
  • Patient has a history of autoimmune disease (systemic lupus erythematosus or dermatomyositis).
  • The subject has a history of exposure to injectable collagen implants.
  • Patient's history includes hypersensitivity to protein pharmaceuticals (monoclonal antibodies or gamma globulins) or collagen.
  • Patient 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.
  • Patient has received any previous exposure to BMP.
  • The patient requires allograft or bone substitute as part of treatment.
  • Patient has history of endocrine or metabolic disorder known to affect osteogenesis (e.g. Paget's disease, renal osteodystrophy, Ehlers-Danlos syndrome, or osteogenesis imperfecta).
  • Patient in the physician's opinion, would not be a good candidate for this surgical procedure.
