Brief Summary:
This pilot clinical trial studies beta-tricalcium phosphate bone graft in treating patients undergoing surgery for metastatic spine cancer. A bone graft may help healing and bone growth in patients undergoing surgery for spine cancer

Condition or disease Intervention/treatment Phase
Adult Spinal Cord Neoplasm Spinal Bone Metastases Spinal Cord Compression Procedure: musculoskeletal complications management/prevention Procedure: bone graft Procedure: quality-of-life assessment Other: questionnaire administration Phase 1

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.

Primary Outcome Measures :
  1. Achievement of durable posterolateral fusion [ Time Frame: Within 12 months ]
    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 :
  1. Achievement of posterolateral fusion [ Time Frame: Up to 12 months ]
  2. Occurrence of subsequent hardware failure [ Time Frame: Every 3 months for 12 months ]
  3. Requirement of additional treatment is for instability [ Time Frame: Within 12 months ]
  4. First documentation of posterolateral fusion [ Time Frame: Within 12 months ]
  5. 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 ]
