About this study

Official title: Evaluation of Safety and Efficency of Custom-made Corpectomy Implants: UNiD 3D VBR

Multicenter study allowing to include the first sixty patients implanted with a custom-made corpectomy implant (UNiD 3D VBR): 30 patient implanted in cervical region and 30 patients implanted in thoracolumbar region.

The main objective is to confirm feasibilty and safety of patient-specific implants for one or multi-level corpectomy and fusion.

This study was approved in March 2016 allowing to include retrospectivley all patients since the first implantation in January 2015 and prospectively all patients after the approval.

Read the detailed description

Anterior cervical corpectomy with fusion (ACCF) has been demonstrated as a good alternative to anterior cervical discectomy and fusion (ACDF) to treat cervical spondylotic myelopathy (CSM). However, the use of vertebral body replacement (VBR) cages is technically demanding, especially to adjust the size of the cage to the defect without compromising the endplate integrity increasing the risk of subsidence. Beside recent studies advocating the interest of the shape, size and design of an implant to achieve fusion and stability in cervical spinal diseases indications, 3D printing offering rapid and patient-specific manufacturing has emerged over the past years. Several materials and technologies can be used and clinical and radiological data are still sparse.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Quantification and description of implant-related adverse events

    To confirm the safety of the surgery with patient specfic implant (UNiD 3D VBR). To quantify and describe adverse events or revision surgeries occuring during follow-up

    Measured: 12 months

Secondary outcomes (9)
  1. Fusion status

    Radiological assessment of bony fusion

    Measured: 6, 12, 24 months

  2. Length of surgery

    Surgeon questionnaire will be used to quantify surgery's length

    Measured: During surgery

  3. Surgical metrics

    Surgeon questionnaire will be used to describe the surgery

    Measured: During surgery

  4. Quality of life

    mJOA: Modified Japanese Orthopaedic Association Score

    Measured: preoperatively and 6,12, and 24 months postoperation

  5. Quality of life

    EMS: European Myelopathy Score

    Measured: preoperatively and 6,12, and 24 months postoperation

  6. Pain

    Visual Analog Score

    Measured: preoperatively and 6,12, and 24 months postoperation

  7. Disability

    Neck disability index

    Measured: preoperatively and 6,12, and 24 months postoperation

  8. Variation of radiological vertebral heights

    Xrays assessment of segmental height operated

    Measured: 6,12, 24 months

  9. Variation of radiological vertebral angulation

    Xrays assessment of C2C7 angle and corpectomy angles

    Measured: 6,12, 24 months postoperativley

Questions about this trial

What is this clinical trial studying?

An observational study of Spinal Cord Compression and Spondylosis, run by Medicrea International at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Quantification and description of implant-related adverse events (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 May 2023.
