Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Indication for surgical instrumentation of the spine (Os Sacrum, L1-L5, Th1-Th12) without or with correction of a malposition.
  • Anatomical adaptation of the rod implant necessary.
  • The trial participant is able to give his/her consent.
  • Signed written declaration of consent after oral and written explanation.
  • Male and female patients aged 18 years and older.
  • Indication for a preoperative CT scan of the lumbar spine
  • Existence of a preoperative planning, which was created on the basis of 3D CT imaging

You may not qualify if:

  • Pregnant or breastfeeding women
  • Emergency situations
  • Other known clinically significant concomitant diseases (e.g. infections, tumors, co-existing arthrosis).
  • Known or suspected incompliance with the protocol, such as drug or alcohol abuse.
  • Inability of the patient to follow the study procedures, e.g., due to language problems, mental illness, dementia, etc.
  • There is no conventional surgical treatment that can be used if the MP cannot be used intraoperatively.
