About this study

Application of 3D printing guide plate in spinal minimally invasive and interventional surgeries

Read the detailed description

This study applies 3D-printed customized guide plate in assisting the accurate puncture in endoscopic spinal surgery, radiofrequency ablation of the medial branch of the dorsal ramus or sensory ganglion or joint, disc coblation nucleoplasty, etc. in patients with low back pain, lumbosacral radicular pain, joint pain, perineal pain and pelvic pain. This technique can shorten reduce the intra-operative radiation, and do not affect the surgical outcome.

This study involved lumbar disc herniation (LDH), lumbar spinal stenosis (LCS), radiculopathy, facet joint disorder syndrome, ischemic pain of the lower extremity, cancer pain, etc.. Spinal minimally invasive and interventional surgeries are effective treatments for these disease. Needle Puncture is the key technology in spinal minimally invasive and interventional surgeries.

In the past when there were no customized guides, the surgeons would place the needle according to his/her previous experience under the guidance of C-arm fluoroscopy or CT. If the position of the needles is not satisfactory, repeated procedure will be performed. This would lead to an increase in the duration of surgery and intra-operative radiation, which is detrimental to both the surgeon and the patient. This problem could be well solved by applying the 3D printing guide plate.

The key processes for the 3D printing guide plate procedure: the model of the spine or bone is established according to the patient's CT scan data to prepare the customized guide plate, then sterilize them for future use. The final position of needle is confirmed by C-arm fluoroscopy or CT.

Being tested
3D printing guide plate, Conventional guidance
Medical subject headings
Intervertebral Disc Displacement, Spinal Stenosis, Radiculopathy, Low Back Pain

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 3D printing guide plateOther

    3D-printed customized guide plate will be used to guide the puncture in the spinal minimally invasive and interventional surgeries. to help to reduce intra-operative radiation.

  • Conventional guidanceOther

    The surgeons would place the needle according to his/her previous experience under the guidance of C-arm fluoroscopy or CT.

Questions about this trial

What is this clinical trial studying?

A study testing 3D printing guide plate and Conventional guidance in people with Lumbar Disc Herniation and Lumbar Spinal Stenosis, run by Peking University Third Hospital at 1 site in China.

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 6 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 1 Nov 2022. 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 China. 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?

Results are not available in the source record.

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

Contact Shuiqing Li (+86 01082265690, bjfdfx@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

C-arm fluoroscopy times (time frame: Intraoperative). 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 1 Nov 2022.
