Study Arms (2)

3D printing guide plate group

EXPERIMENTAL

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

Other: 3D printing guide plate

Conventional guidance group

ACTIVE COMPARATOR

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

Other: Conventional guidance

Interventions

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.

3D printing guide plate group

Eligibility Criteria

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

You may qualify if:

  • Age ≥18 years old,
  • Pain lasting ≥12 weeks,
  • The previous failure of conservative management such as physiotherapy, exercise therapy, or analgesic medications,
  • Pain intensity≥4 out of 10 on the numerical rating scale (NRS),
  • Availability of computed tomography/magnetic resonance imaging findings of pathology concordant with the side and level of their clinical features,
  • Agree with spinal minimally invasive and interventional surgery treatments, including endoscopic spinal surgery, radiofrequency treatment of the medial branch of the dorsal ramus or nerve root or sensory ganglion or joint, disc coblation nucleoplasty, etc.

You may not qualify if:

  • Patient refusal to participate in the study,
  • Pregnant or nursing
  • Allergies to local anesthetics, contrast dyes or steroids
  • Significant anatomic deformity (either congenital or acquired) making it difficult to access the foramen as evidenced by computed tomography/magnetic resonance imaging
  • Patients with platelet dysfunction, bleeding disorder or continuing anticoagulant treatment
  • Steroid injection within the previous 12 weeks,
  • Systemic infection,
  • Injection site infection,
  • Unstable medical or psychiatric condition
