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

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.

Exclusion criteria

* Status-post previous fusion with allogeneic bone graft

Design outcomes

Primary

MeasureTime frameDescription
Achievement of durable posterolateral fusionWithin 12 monthsMeasured 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

MeasureTime frame
Requirement of additional treatment is for instabilityWithin 12 months
Achievement of posterolateral fusionUp to 12 months
Occurrence of subsequent hardware failureEvery 3 months for 12 months
First documentation of posterolateral fusionWithin 12 months
Occurrence of pain or disability experienced after surgery that is related to spinal metastasis or is a consequence of the resulting treatmentEvery 3 months for 12 months
