Minuteman® G5 Interspinous-Interlaminar Fusion/Decompression

Minuteman® is a minimally invasive spinal stabilization device implanted between the spinous processes to help restore alignment, maintain spacing, and reduce pressure on affected nerves. Performed through a small lateral incision using image guidance, the procedure is designed to provide structural support and decrease pain associated with lumbar instability or nerve compression. For many patients, Minuteman® can improve mobility, reduce discomfort, and help restore daily function without the need for traditional open surgery.

Quick facts

  • Setting: Outpatient, image-guided
  • Time: ~45–75 minutes
  • Anesthesia: Local with sedation
  • Incision: Small lateral approach
  • Recovery: Same day; activity restrictions for several weeks

Who it helps

  • Pain from lumbar instability or spondylolisthesis (selected grades)
  • Neurogenic claudication from foraminal compromise
  • Patients who have not improved with conservative care

How it works

Through a small incision, your provider positions the Minuteman® implant between spinous processes to stabilize the segment and maintain space for nerves. Bone graft may be added to promote fusion.

What to expect

  • Before: Imaging confirms candidacy; medication review
  • During: Small incision, fluoroscopic guidance, device placement
  • After: Soreness common; avoid bending/twisting/lifting as instructed; follow-up imaging as needed

Benefits & risks

  • Benefits: Small incision, less tissue disruption than open surgery, stabilization with potential decompression
  • Risks: Infection, bleeding, implant-related issues, non-union, nerve irritation; not appropriate for all anatomies

Is it right for me? (Checklist)

  • ✅ Diagnosed segmental instability or stenosis correlating with symptoms
  • ✅ Failed conservative therapies
  • ✅ Able to follow post-procedure restrictions
