Primary Outcome Measures:
  • Achievement of durable posterolateral fusion [ Time Frame: Within 12 months ] [ Designated as safety issue: No ]
    Measured from x-ray and/or computed tomography (CT) scans. Standard criteria of determining fusion is visualization of continuous trabeculating bone bridging the transverse processes and facets on AP and lateral x-rays or when there is < 2 degree angular motion and < 2mm of translation on standing flexion and extension radiographs.

Secondary Outcome Measures:
  • Achievement of posterolateral fusion [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
  • Occurrence of subsequent hardware failure [ Time Frame: Every 3 months for 12 months ] [ Designated as safety issue: No ]
  • Requirement of additional treatment is for instability [ Time Frame: Within 12 months ] [ Designated as safety issue: No ]
  • First documentation of posterolateral fusion [ Time Frame: Within 12 months ] [ Designated as safety issue: No ]
  • Occurrence of pain or disability experienced after surgery that is related to spinal metastasis or is a consequence of the resulting treatment [ Time Frame: Every 3 months for 12 months ] [ Designated as safety issue: No ]

Detailed Description:
OBJECTIVES: I. To determine if Chronos (beta-tricalcium phosphate bone graft) will form a posterolateral fusion mass in patients undergoing fusion surgery for spine cancer within 12 months. II. To evaluate quality of life following the use of ChronOS as measured by (a) pain (or lack of pain) associated with pseudoarthrosis and (b) the need for additional treatment for instability as a result of hardware failure. OUTLINE: Patients undergo placement of beta-tricalcium phosphate bone graft strips posterolaterally during surgery. After completion of study treatment, patients are followed up at 1 month and then every 3 months for 1 year.

Genders Eligible for Study:   Both

Inclusion Criteria:

  • All patients undergoing surgery for spinal decompression for tatic spine cancer who require bone substitute for a posterolateral spinal fusion
  • Patients may or may not have posterolateral instrumentation

Exclusion Criteria:

  • Status-post previous fusion with allogeneic bone graft
