NCT00635843

Brief Summary

The purpose of this clinical trial is to assess the safety and effectiveness of the MAVERICK™ Total Disc Replacement as a method of treating patients with lumbar degenerative disc disease at one level from L4-S1, with overall success being the primary endpoint of the clinical trial. The primary objective is to show non-inferiority of the investigational device to the control treatment. If non-inferiority is established, superiority will be examined.

Study Arms (2)

MAVERICK™ Disc

EXPERIMENTAL
Device: MAVERICK™ Disc

Fusion

ACTIVE COMPARATOR
Device: LT-CAGE® Lumbar Tapered Fusion Device and INFUSE® Bone Graft

Interventions

The MAVERICK™ disc is a spinal arthroplasty system and is intended to replace a damaged disc in the lumbar spine. It is a permanent implant used to maintain motion at the treated level and is inserted using an anterior surgical approach.

Also known as: MAVERICK™
MAVERICK™ Disc

The control is the treatment with LT-CAGE® Lumbar Tapered Fusion Device and INFUSE® Bone Graft. It is commercially available for anterior lumbar spine interbody fusion procedures.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Has DDD as noted by back pain of discogenic origin, with or without leg pain, with degeneration of the disc confirmed by patient history
  • Has 1 or more of the following documented by CT, MRI, or plain x-rays: modic changes, high intensity zones in the annulus, loss of disc height, decreased hydration of the disc
  • Has documented annular pathology
  • Has single-level symptomatic degenerative involvement from L4-S1 requiring surgical treatment
  • Has intact facet joints at the involved vertebral levels documented by CT and/or MRI
  • Has preop Oswestry score≥30
  • Has preop back pain score ≥20
  • Age 18 to 70 yrs who are skeletally, mature, inclusive
  • Has not responded to non-operative treatment for 6 mos
  • If child-bearing potential, patient is non-pregnant, non-nursing, and agrees not to become pregnant for 1 yr after surgery
  • Is willing and able to comply with the study plan and sign the Patient Informed Consent Form

You may not qualify if:

  • Has primary diagnosis of a spinal disorder other than DDD at involved level
  • Had previous posterior lumbar spinal fusion surgical procedure at involved level
  • Had prior posterior lumbar surgery resulting in significant muscle/ligament morbidity, not including facet saving techniques
  • Had previous anterior lumbar spinal surgery at involved level
  • Requires spinal fusion and/or arthroplasty at more than 1 lumbar level
  • Has severe pathology of facet joints of involved vertebral bodies
  • Has any posterior element insufficiency
  • Has spondylolisthesis
  • Has spinal canal stenosis
  • Has rotatory scoliosis at involved level
  • Level treated has fractures secondary to trauma
  • Has any of the following that may be associated with a diagnosis of osteoporosis (if Yes, a DEXA Scan is required): Postmenopausal Non-Black female over 60 yrs of age and weighs less than 140 pounds; Postmenopausal female that has sustained a non-traumatic hip, spine or wrist fracture; Male over the age of 60 that has sustained a non-traumatic hip or spine fracture. If level of BMD is -3.5 or lower or -2.5 or lower with vertebral crush fracture, the patient is excluded
  • Has fever (temp \> 101°F oral) at time of surgery
  • Has a condition that requires postop medications that interfere with fusion, such as steroids or prolonged use of non-steroidal anti-inflammatory drugs, excluding routine perioperative, non-steroidal anti-inflammatory drugs. Does not include low dose aspirin for prophylactic anticoagulation
