This rapid assessment concerns the clinical effectiveness and the efficiency of innovative surgical technologies proposed for the treatment of degenerative spinal conditions: interspinous spacers and pedicle screw systems. These techniques are presented as an alternative to decompression surgery (laminectomy or discectomy) and/or fusion surgery. Currently, none of these implants are officially reimbursed in Belgium. However, in practice, a specific reimbursement can be obtained for some elements of the pedicle screw systems (cords and pedicle screws). This report follows the standard methodology of HTA reports of the KCE, without deeply considering patient issues, ethical issues and organisational issues.
