Study Description
Brief Summary:
The CopiOs Bone Void Filler (BVF) is a synthetic bone graft material consisting of calcium phosphate dehydrate within lyophilized type I bovine collagen that has been formed into pads of various sizes for surgical implantation. Pre-clinical animal studies suggest that the bone healing strength of CopiOs to be equivalent to autograft.

Condition or disease
Spinal Fusions

Detailed Description:
Purpose of the study is to evaluate the in-vivo use of CopiOs bone void filler in a single site trial, providing pre and post-operative evaluations of subjects undergoing spinal fusion with autogenous bone graft, in whom the CopiOs has been used as a bone void filler in the post-harvest iliac crest.

Study Population
CopiOs will be used to fill the bony deficit as a result of iliac crest autograft harvest during spinal fusion surgery.

Inclusion Criteria:

  • Patient is 18 years and older
  • Patient must be an appropriate candidate for iliac crest bone harvesting during a spinal fusion.
  • Patient must be skeletally mature.
  • Patient has signed an IRB approved Informed Consent and HIPAA compliant waiver.

Exclusion Criteria:

  • Patient is suffering from any co-morbidities that would excessively increase the risk of surgery, including but not limited to pulmonary or cardiac conditions.
  • Patient is pregnant.
  • Patient has a severe degenerative bone disease.
  • Patient has systemic conditions which would affect bone or wound healing.
  • Patient is unwilling or unable to follow postoperative instructions or cooperate in a follow-up program.
  • Patient is suffering from mental illness, alcohol abuse or drug abuse.
  • Patient has known allergies to bovine collagen.
  • Patient has a history of multiple allergies.
  • Patient has infection at the surgical site.
  • Significantly impaired vascularity proximal to surgical site.
  • Sites are in direct contact with articular space.
  • Sites where stresses on void will exceed the load strength of fixation hardware.
  • Patient has hypercalcemia.
