Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study looks at a special putty called Fibergraft used in spine surgery to help bones grow together. About 80 adults with back pain or nerve problems from spine issues will get this putty during surgery. Doctors will check how well the bones heal using CT scans and ask patients about their recovery. The goal is to see if this material works well without needing extra bone from elsewhere.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults ≥ 18 years old * Diagnosed with the following lumbar spine disorders: foraminal nerve root compression, isthmic spondylolisthesis, and short-segment (1-2 levels) deformity. * Undergone primary surgery of ALIF or XLIF using titanium cages filled with standalone Fibergraft and with the following criteria fulfilled (ie, the index surgery): * ALIF (up to 2 levels) as either standalone (ie, no posterior procedure) or as an anterior first procedure with posterior procedure as a second procedure. * XLIF (up to 2 levels) as an anterior first procedure with posterior procedure as a second procedure. * Consenting to have CT scans taken to allow assessment of fusion status at 12-24 months post index surgery * This criterion is applicable to patients who have not undergone revision surgery. * For patients who have undergone revision surgery due to any reason other than nonunion, which typically occurs within 1 year of the index surgery, this criterion is only applicable if it is possible to obtain the CT scan within 12-24 months of the index surgery. If no CT scan can be taken during this window, the patient does not need to undergo the CT scan; in such cases, the CT scan that has been taken as part of the standard of care before the revision surgery will be retrospectively retrieved to assess the fusion status at the time of the revision surgery. * This criterion is not applicable to patients who underwent revision surgery due to nonunion, which typically occurs 1 year after the index surgery; these patients do not need to undergo the CT scan. In such cases, the CT scan that has been taken as part of the standard of care before the revision surgery will also be retrospectively retrieved to assess and grade the fusion status at the time of the revision surgery. * Ability to provide informed consent according to the IRB/EC defined and approved procedures Exclusion Criteria: * Revision surgery * Standalone XLIF * Posterior lumbar interbody fusion * Diagnosis of fractures, malignancies, ankylosing spondylitis, or acute cauda equina syndrome * Diagnosis of Parkinson's disease * Body mass index \> 35kg/m2
