Clinical Investigation of MONTAGE in Adults With Spinal Deformity Undergoing Pedicle Subtraction Osteotomy

Ankylosing Spondylitis Clinical Trial

Official title: A Prospective, Multicenter, Randomized, Controlled Clinical Investigation of MONTAGE in Adults With Spinal Deformity Undergoing Pedicle Subtraction Osteotomy

Status Terminated

Clinical Trial Summary

This study evaluates the difference in postoperative bleeding between two study groups, FDA cleared MONTAGE Settable Resorbable Hemostatic Bone Putty and standard of care (no bone hemostat) during pedicle subtraction osteotomy procedures.

Clinical Trial Description

Pedicle Subtraction osteotomy (PSO) is a surgical option for treating several spinal deformities. It has been utilized in alignment disorders of the fused spine, in the lumbar spine to treat large sagittal deformities and in patients with ankylosing spondylitis with thoracolumbar kyphotic deformity.

PSO typically results in substantial loss of blood (as much as 2L) with a significant portion of the loss likely occurring at the osteotomy surfaces post-surgically. The control of peri-operative blood loss is considered a critical issue by spine surgeons. A variety of methods have been proposed for the reduction of blood loss during or immediately after spine surgery, including preoperative use of erythropoietin, autologous blood, cell salvage, intra-operative controlled hypotension, and the use of anti-fibrinolytic drugs. Bone hemostats have traditionally not been part of the standard of care to promote hemostasis probably because most traditional options (e.g., bone wax) are nonabsorbable and thus might interfere with fusion at the osteotomy site.

MONTAGE is a settable (hardening) bioabsorbable polymer and hydroxyapatite/beta tricalcium phosphate based putty, used in the control of bleeding from bone during spine, orthopedic, craniomaxillofacial, thoracic and other surgical procedures, and has been FDA cleared. ;
